13 ERA-CAPS - Dimorphic fruits, seeds and seedlings as adaptation mechanisms to abiotic stress in unpredictable environments

SeedAdapt项目的目的是阐明一年生植物物种中与果实/种子相关的早期生活史性状作为非生物胁迫适应的分子机制。高等植物的传播单位--散生孢子，这里是果实和种子--支持着后代的分布和早期生活史。我们的项目将使用比较的方法来了解的二态性的水囊（果实/种子）综合征上产生的同一植物的一年生Aethionema物种（姐妹的所有核心拟南芥科，白菜科），并提供不同的适应作为一个休眠赌注对冲策略。Aethionema arabicum基因组的可用性将有助于我们的表观基因组，激素和转录组在敏感的发育过程中与非生物胁迫的比较研究。我们建议，调查水果，种子和幼苗性状多样性的监管基础是理想的整合新技术和互补的专业知识，以研究生态学，进化，种子工业和作物育种领域的最重要的。

The aim of the SeedAdapt project is to elucidate the molecular mechanisms of fruit/seed-related early-life history traits that evolved in annual plant species as adaptations to abiotic stresses. Higher plant dispersal units - diaspores, here: fruits and seeds - support the distribution and early life history of the progeny. Our project will use a comparative approach to understand the dimorphic diaspore (fruit/seed) syndromes produced on the same plant of annual Aethionema species (sister of all core Brassicaceae, cabbage family) and provide distinct adaptations as a dormancy bet-hedging strategy. The availibility of the Aethionema arabicum genome will facilitate our comparative investigation of the epigenomes, hormonomes and transcriptomes in relation to abiotic stress during sensitive developmental processes. We propose that investigating the regulatory basis of fruit, seed, and seedling trait diversity is ideal for integrating new technologies and complementary expertise in order to study a field with utmost importance in ecology, evolution, seed industry and crop breeding.
