衰老是叶片生活史的最后阶段，植物将叶片中的营养物质重新分配到其他发育中的器官。最近的工作集中在了解基于网络的分子机制，该机制结合了各种环境信号和叶龄信息，涉及到一个复杂的过程，涉及多个途径的协调作用。在此，我们发现了一个新的参与叶片衰老调控的基因，命名为LSR1(Leaf Senthy Related 1)。功能缺失的Isr1-1突变体表现出延缓叶片衰老的表现，而LSR1过表达则加速了叶片衰老。LSR1编码一种脂转移蛋白，结果表明该蛋白定位于叶绿体和细胞间隙。LSR1基因可能通过脂类运输参与植物叶片衰老的调控。
Senescence is the final stage in the life history of a leaf, whereby plants relocate nutrients from leaves to other developing organs. Recent efforts have begun to focus on understanding the network-based molecular mechanism that incorporates various environmental signals and leaf age information and involves a complex process with the coordinated actions of multiple pathways. Here, we identified a novel participant, named LSR1 (Leaf Senescence Related 1), that involved in the regulation of leaf senescence. Loss-of-functionlsr1-1mutant showed delayed leaf senescence whereas the overexpression ofLSR1accelerated senescence. LSR1 encodes a lipid transfer protein, and the results show that the protein is located in chloroplast and intercellular space. The LSR1 may be involved in the regulation of leaf senescence by transporting lipids in plants.
