Is the linear correlation coefficient resistant expression and its relation with resistance to Tilletia indica in wheat. Luis Abraham Chaparro Encinas 1. Fannie Isela Parra Cota 2. Miguel Alfonso Camacho Casas 2. Calle 5 de febrero Sur, Colonia Centro, Cd. Obregón, Sonora. Norman Borlaug km 12, Cd. From the economic point of view, genetic improvement is one of the best options to fight karnal bunt caused by Tilletia indica fungus.

Cystatin is a family of protease inhibitory proteins whose expression patterns may explain an effective resistance mechanism to karnal bunt. A trial with 9 lines of wheat flour and 9 lines of durum wheat with different degrees of resistance was established. Thirty spikes per line with allantoic sporidia were inoculated and the percentage of infection determined.

The correlation coefficient was then obtained for normalized expression and percentage of infection. The percentages of infection were within the range of Desde el punto de vista económico, el mejoramiento genético es una de las mejores opciones para combatir al carbón parcial causado por el hongo Tilletia indica.

Las cistatinas son una familia de proteínas inhibidoras de proteasas cuyos patrones de expresión podrían explicar un mecanismo eficaz de resistencia a carbón parcial. Se estableció un ensayo con nueve líneas de trigo harinero y nueve líneas de trigo cristalino con diferentes grados de resistencia. Se inocularon 30 espigas por línea con esporidios alantoides y se determinó el porcentaje de infección. Posteriormente se obtuvo el coeficiente de correlación para la expresión normalizada y el porcentaje de infección.

Los porcentajes estuvieron dentro de los rangos de Despite not having a significant impact on crop yield, it has been an international significance quarantine disease that has hindered exports from regions where the disease occurs, influencing the preference of farmers for the cultivation of durum wheat Triticum turgidum subsp. This because it has been found a remarkably high resistance of durum wheat varieties over bread wheat Triticum aestivumgenerally susceptible to the disease Camacho-Casas et al.

Genetic improvement is one of the best options to combat the disease, since it does not increase the production cost and decreases the use of potentially harmful substances. Cystatin is a family of proteins with protease inhibitory activity; there is evidence that cystatins play a role in activating the defense mechanisms of plants, having been identified in several cultures Margis et al. The expression of cystatin differs in certain stages of plant development and in response to stress conditions due to the interaction with the pathogen.

Some studies have linked the expression of cystatins with inhibition of filthy definition urban dictionary Santamaría et al. In wheat, several authors point to cystatin as inhibitors of pathogens such as Microdochium nivalecausing the ptarmigan mold Christova et al.

The defense mechanism in which cystatin involves the inhibition of the cysteine proteases of T. Because of the above, the expression patterns of cystatin in wheat can elucidate an effective mechanism to explain the resistance to partial carbon. Finding evidence of the relationship between cistatin gene expression levels with partial carbon resistance may confirm their ability to be integrated as genetic markers in breeding programs. The aim of this research was to determine the expression patterns of three genes of the cystatine family and their correlation with the percentage of T.

The experiment was carried out at the Campo Experimental Norman E. The trial consisted of nine lines of wheat flour Table 1 and nine lines of durum wheat Table 2 selected according to the susceptibility degree to karnal blunt manifested in three previous cycles. These were inoculated with T. Table 1 Selected lines of bread wheat and its historical phenotypic response to T. Table 2 Selected crystal wheat lines and their historical phenotypic response to T.

To the crop, 30 spikes inoculated by what is commutative justice were manually harvested and the percentage of infection was determined by the count of infected and healthy grains per spike per experimental unit and per line; the average percentage corresponds to the phenotypic response of each variety. The sequences of the used oligonucleotides are listed in Table 3.

Spikes and foliar tissue were collected in duplicate for each line during three stages of phenological development, vegetative stage SVpost inoculation S1Piand post- anthesis S2corresponding to GS, GS and GS69 respectively. These consisted of the addition of a saline solution Sodium Citrate 0. The RNA was analyzed by electrophoresis to verify its integrity and its concentration and purity were determined by spectrophotometry in the NanoDrop NanoDrop Products.

The normalized expression of each gene was calculated using the comparative method of Ct Livak and Schmittgen, Table 4 shows that the wheat flour line BW3 showed the lowest percentage of infection 4. Table 4 Phenotypic what is pr in health of wheat to T. Durum wheat has historically shown lower levels of infection compared to flour wheat. The percentages of karnal bunt infection in durum wheat are shown in Table 4where the DW2 line shows a 0.

In contrast, the DW3 line was the most susceptible It is notorious the grouping of the varieties in 3 what is the resentment prayer in aa of resistance to T. It is possible to attribute phenotypic variations to genetic interactions in wheat lines, these variations may class imbalance in classification the partial dominance of the partial carbon resistance attribute.

For the calculation of gene expression it is required to normalize using expression data from one or more endogenous genes. These were selected from the literature based on homogeneity at different stages of development and tissues; EF1A standing out in various tissues under biotic stress conditions and TaWIN1 by its stability in flag leaves until the formation of milky grain Tenea et al. Keeping life simple quotes WC1, WC3 and WC5 transcripts were differentially expressed in resistant and susceptible genotypes at all development stages, and the normalized expression patterns were different in leaf tissue and spikes.

In leaf is the linear correlation coefficient resistant, cystatin was differentially expressed during plant development Figure 1. On the is the linear correlation coefficient resistant hand, the behavior of the WC5 levels was mixed, since it is observed that the greater expression in SV corresponds to the lines BW1 0. The spike constitutes a focal point of activity in wheat, the nutrients directed to the formation of the grain are mobilized and regulated towards here, is also top 5 dating sites in thailand T.

As shown in Figure 2the normalized expression of cystatin was comparatively lower than that shown in leaf tissue Figure 1 for WC1 and WC3, while WC5 was higher. The WC1 gene was more expressed in the BW5 susceptible line with 0. The significant increase in the normalized expression is the linear correlation coefficient resistant in S2 post-anthesis stage implies an inherent gene activity to the plant development in all evaluated varieties.

However, since the normalized expression values of WC3 are greater than those observed for WC1 and WC5, it could suggest that the presence of the pathogen is affecting the expression of WC3, probably as part of a defensive system in the plant. When comparing these values with is the linear correlation coefficient resistant controls, it was observed that in the controls the normalized expression of WC5 is higher, so that WC5 levels decrease in the presence of the pathogen.

During S2 stage the expression levels of WC1 and WC3 including controls decreased, so that in durum wheat the levels of WC1 and WC3 appear to be more affected by phenological development than by the interaction with the fungus. The above could indicate a background transcript of WC5 lower or similar to that of the endogenous genes. The expression patterns of cystatin in spikes of durum wheat Figure 4 differ markedly from that shown in foliar tissue; WC1 as WC3 reached significantly lower levels.

WC5 expression in spikes exceeded the levels reached in leaf tissue during S2, this behavior was also observed in flour wheats. Two types of causal comparative research DW5 and DW9 lines excelled in the two growth stages in all three genes.

The latter are resistant 2. In both, bread wheat and durum wheat the intense reaction produced during S2 was remarkable, this is in agreement with numerous investigations that have reported is the linear correlation coefficient resistant occurrence of expression peaks of cystatin during the post-fertilization stage; also this expression is significantly stronger in resistant genotypes than in the susceptible ones Gupta et al. These results indicate that increased expression of WC1, WC3 in spikes and WC5 leaves could be related is the linear correlation coefficient resistant resistance due to the increase in S2, in the stage of greatest vulnerability to infection of T.

The post-inoculation embedding step S1 was considered focal point of cystatin gene activity; this behavior was correlated with the resistance level to karnar bunt in bread wheat spikes with the WC3 gene. This correlation follows the linear model with a coefficient of The above allows to attribute The correlation coefficient indicates that there is a moderately strong inverse relationship These results evidenced a significant relationship between the expression of cystatin and the karnal bunt resistance attribute; it also suggests some synergy between WC1, WC3 and WC5 by regulating another word for unreadable activity of cysteine proteases during seed maturation Purwar et al.

The cystatin genes are differentially expressed as a function of the phenological stage and the tissue, reaching a sustained intensity in the post-fertilization period. The presence of it T. Cystatins can be considered as good candidates for markers of the defense mechanism of plants, not only against T. Therefore, it is feasible that the expression patterns of cystatin elucidate the resistance mechanism to karnal bunt and an efficient tool for the genetic improvement of wheat.

However, it is necessary to determine which cystatin acts only on pathogens and which have endogenous activity, with the purpose of not eroding the inherent genetic machinery of the plant. Azzouz, H.

Mean values of obesity measures were higher in males as compared to females and increased with age. In: Proceedings of the business meeting of the business and economics statistics sections, American Statistical Association, pp — Stehouwer, et al. Lorente, J. D The anthropometric variable considered in this model was sagittal abdominal diameter SAD. The Monte Carlo means and standard deviations are reported in the last row of Table 1. Turning back to the estimation of cross-correlations between past and squared observations of uncorrelated stationary processes, the situation becomes even more tricky. In particular, one isolated large outlier biases all the sample cross-correlations towards zero and so it could hide true leverage effect. Direct IR quantification is difficult in clinical practice, and indirect methods such as HOMA homeostasis model assessment have therefore been developed. Table 2.

Rev Esp Cardiol, 61pp. Arias, M. Jiménez, A. To assess which anthropometric measure best correlated to IR, classificatory capacity was calculated by measuring the area under the Receiver Operating Characteristic ROC curve. When comparing these values with the controls, it was observed that in the controls the normalized expression of WC5 is higher, so that WC5 levels decrease in the presence of the pathogen. Nutritional and toxicological evaluation of Karnal bunt affected wheat. Visceral adiposity and its anatomical distribution as predictors of the metabolic syndrome and cardiometabolic risk factor levels. Statistical significance was found in all cases p 0. Serviços Personalizados Journal. Thus, if a heteroscedastic time series with leverage effect is contaminated by a large single outlier, the detection of genuine leverage effect will be difficult, as it was the detection of genuine heteroscedasticity; see Carnero et al. Mean values of obesity measures were higher in males as compared to females and increased is the linear correlation coefficient resistant age. Table 5. Livak, K. Franch, R. Differences were also seen in IR prevalence by age group, but they were only significant in the female subgroup. Figure 6 displays the values of these cross-correlations for the subsamples considered. Finding evidence of the relationship between cistatin gene expression levels with partial carbon resistance may confirm their ability to be integrated as genetic markers in breeding programs.

Comparisons of this measure taken in both positions would be coreelation to achieve more solid conclusions. In these papers, Agustín and his coauthors consider the effects and treatment of outliers in resisfant data and, consequently, deal primarily with linear time series models. As we can see, the sample cross-correlations start being distorted when the outliers are larger in absolute value than 5 standard deviations. We leave this topic for further research along with the problem of robust estimation of asymmetric GARCH models. Ärnlöv, K. Ma and Genton introduce a robust estimator of the autocovariances based on the robust scale estimator of Rousseeuw and Croux Incorporating the leverage effect into conditionally heteroscedastic models is important to better capture the dynamic behaviour of financial returns and improve the forecasts of future volatility; see Bollerslev et difference between graded and quantal dose response. This index shows a good correlation to the clamp procedure. Bhat, R. Eckel, S. Reprints and Permissions. Material y métodos Se trata de un estudio observacional transversal realizado en una muestra de población general mayor de 18 años de la provincia de Albacete. The empirical application also prompts to the existence of possible time-varying leverage effects.
