Regulatory Networks during Developmental Phase Transitions and Abiotic Stresses

我实验室的研究重点是了解控制从胚胎发育到营养阶段过渡的分子机制。这一相变与休眠的打破和萌发的开始相一致。控制胚胎向营养阶段转变的机制知之甚少，尽管它们在世界范围内极大地影响作物产量。例如，现代农业中与种子休眠密切相关的一个问题是种子在收获前发芽（胎生），当时仍然附着在田间的母体植物上。这导致谷物质量下降和各种谷物的经济损失。因此，在不影响其他生长参数的情况下，在某些谷物品种中重新引入休眠有很大的兴趣。

Research in my laboratory focuses on understanding the molecular mechanisms that control the transition from the embryonic to the vegetative phase of development. This phase transition coincides with the break of dormancy and the onset of germination. The mechanisms controlling the embryonic-to-vegetative phase transition are poorly understood, despite the fact that they greatly affect crop yields worldwide. For instance, a problem in modern agriculture tightly linked to seed dormancy is pre-harvest sprouting of seeds (vivipary), when still attached to the mother plant in the field. This results in reduced grain quality and financial losses in a wide range of cereals. Therefore, there is great interest in reintroducing dormancy in certain cereal varieties without affecting other growth parameters.
