植物群落的组成和结构在气候变暖下发生了显著变化,尤其是在高海拔和寒冷地区。然而,由于植物群落结构变化和生态系统功能改变之间的联系非常复杂,气候变暖引起的植物群落组成和结构变化对高寒生态系统碳循环的影响及其机制尚不明确。群落加权的植物功能性状可以为我们全面理解植物群落和碳循环对气候变暖的响应提供重要的依据,因为植物功能性状直接反映了植物的生态策略,并与生态系统功能的变化密切相关。

SWI/SNF染色质重塑复合体通过利用ATP水解所产生的能量改变染色质的结构来调节基因转录。SWI/SNF染色质重塑复合体在酵母,哺乳动物和植物中都相当保守。酵母的SWI/SNF主要由8-14个亚基组成,而动物中的SWI/SNF复合体则由29个基因编码组装而成。在模式植物拟南芥中,编码SWI/SNF复合体的亚基的基因突变会导致一系列严重的发育异常表型。虽然人们认为典型的植物SWI/SNF复合物主要...
