Seeds are involved in the transmission of microorganisms from one plant generation to the next and consequently act as reservoirs for the plant microbiota. The driving processes influencing seed microbiota assemblage have not been yet deciphered because of confounding factors related to environmental location, agricultural practices and host genoty...
1. Seed longevity, the maintenance of viability during dry storage, is a crucial factor to preserve plant genetic resources and seed vigor. Inference of a temporal gene-regulatory network of seed maturation identified auxin signaling as a putative mechanism to induce longevity-related genes. 2. Using auxin-response sensors and tryptophan-dependent ...
Les caprins sont une espèce à reproduction saisonnée. C’est la sécrétion de mélatonine, qui dépend des variations de la durée du jour au cours de l’année, qui régule ces périodes d’activité et de repos sexuels. Chez les boucs de centre d’insémination, la qualité et la quantité de semence dépendent du rythme photopériodique auquel ils sont soumis. A...
Male gamete biology shows specific features in birds that contribute to the reproductive strategy of flying animals adapted to highly variable environmental conditions. In this paper, we review the main characteristics of bird sperm, their selection and storage in the highly specialized female oviduct, specific features of polyspermic fertilization...
