1Arabidopsis Coordinates the Diurnal Regulation of Carbon Allocation and Growth across a Wide Range of Photoperiods显示文摘在短光周期,植物在光更快积累淀粉并且降级它更慢慢地在夜里,保证他们的淀粉储备持续直到黎明。为了调查伴随,在预定生长变化, Arabidopsis 在光周期的一个范围被种并且在黎明和黄昏为插座生物资源,光合作用,呼吸,核糖体丰富,装载的 polysome,淀粉,和超过 40 代谢物分析。数据集合被用来在白天和夜里为生长率建模,并且识别与生长相关的代谢物。建模的生长率并且 polysome 装载在白天并且在在长光周期的夜里高,但是在短光周期在夜里减少了。核糖体丰富在所有光周期是类似的。淀粉的数量怎么在轻时期,夜里的长度,和维护费用积累了,被讨论交往在短光周期在夜里抑制生长,并且为优化核糖体使用改变策略。重要关联在在生长率和糖信号 trehalose 6 磷酸盐和氨基酸生合成中介 shikimate 的层次之间的白天和夜里被发现,识别象在协调生长与的一个网络的中心的这些代谢物日报在碳供应的变化。Ronan Sulpice Anna Flis Alexander A.

2Primary carbohydrate metabolism genes participate in heat-stress memory at the shoot apical meristem of Arabidopsis thaliana显示文摘In plants, the shoot apical meristem (SAM) is essential for the growth of aboveground organs. However, little is known about its molecular responses to abiotic stresses. Here, we show that the SAM of Arabidopsis thaliana displays an autonomous heat-stress (HS) memory of a previous non-lethal HS, allowing the SAM to regain growth after exposure to an otherwise lethal HS several days later. Using RNA sequencing, we identified genes participating in establishing the SAM's HS transcriptional memory, including the stem cell (SC) regulators CLAVATA1 (CLV1) and CLV3, HEAT SHOCK PROTEIN 17.6A (HSP17.6A), and the primary carbohydrate metabolism gene FRUCTOSE-BISPHOSPHATE ALDOLASE 6 (FBA6). We demonstrate that sugar availability is essential for survival of plants at high temperature. HEAT SHOCK TRANSCRIPTION FACTOR A2 (HSFA2A) directly regulates the expression of HSP17.6A and FBA6 by binding to the heat-shock elements in their promoters, indicating that HSFA2 is required for transcriptional activation of SAM memory genes. Collectively, these findings indicate that plants have evolved a sophisticated protection mechanism to maintain SCs and, hence, their capacity to re-initiate shoot growth after stress release.Justyna Jadwiga Olas Federico Apelt Maria Grazia Annunziata Sheeba John Sarah Isabel Richard Saurabh Gupta Friedrich Kragler Salma Balazadeh Bernd Mueller-Roeber 2021Molecular Plant2021,14,9:1
