Gundel, Pedro E. Ghersa, Claudio M. Elsevier; Basic and Applied Ecology; 13 1 ; Plant fitness is enhanced by resource allocation to seed number offspring number or weight offspring survival. Besides, there is a well known trade-off in resource allocation between both traits. Symbiotic interactions can influence plant resource allocation to reproduction, yet little research has been performed in this direction.

We studied the consequences of a grass—fungus symbiosis on the trade-off between seed number and weight, using Lolium multiflorum and the endophyte Neotyphodium occultans as our study system. In difference between symbiotic and non symbiotic relationship terms, we experimentally removed N. In evolutionary terms, we compared reproductive allocation between symbiotic vs.

All plants showed a negative association between seed number and weight, once standardized for total reproductive biomass. Under high nutrient availability, endophyte-symbiotic plants showed higher seed weight than non-symbiotic plants for any seed number. However, no differences were observed under low nutrient availability. Endophyte influence also varied according to L. Windows 11 cant connect to samsung tv results implied a higher plasticity in seed weight and lower plasticity in seed number for symbiotic plants.

Indeed, endophyte-symbiotic plants showed an overall lower slope in the association between seed number and total reproductive biomass than non-symbiotic plants. Our results suggest that N. We propose that symbiotic interactions may influence the evolution of seed number and weight trade-off. Gundel Trade-off between seed number and weight - Influence of a grass—endophyte symbiosis.
