Light serves as a crucial environmental cue which modulates plant growth and development, and which is controlled by multiple photoreceptors including the primary red light photoreceptor,phytochrome B(phyB). The signaling mechanism of phyB involves direct interactions with a group of basic helix-loop-helix(bHLH) transcription factors, PHYTOCHROME-INTERACTING FACTORS(PIFs), and the negative regulators of photomorphogenesis, COP1 and SPAs. H2 A.Z is an evolutionarily conserved H2 A variant which plays essential roles in transcriptional regulation. The replacement of H2 A with H2 A.Z is catalyzed by the SWR1 complex. Here, we show that the Pfr form of phyB physically interacts with the SWR1 complex subunits SWC6 and ARP6. phyB and ARP6 coregulate numerous genes in the same direction,some of which are associated with auxin biosynthesis and response including YUC9, which encodes a rate-limiting enzyme in the tryptophandependent auxin biosynthesis pathway. Moreover,phyB and HY5/HYH act to inhibit hypocotyl elongation partially through repression of auxin biosynthesis. Based on our findings and previous studies, we propose that phyB promotes H2 A.Z deposition at YUC9 to inhibit its expression through direct phyB-SWC6/ARP6 interactions,leading to repression of auxin biosynthesis, and thus inhibition of hypocotyl elongation in red light.

Light is an essential environmental signal perceived by a broad range of photoreceptors in plants. Among them, the red/far-red light receptor phytochromes function to promote photomorphogenesis, which is critical to the survival of seedlings after seeds germination. The basic-helix-loop-helix transcription factors phytochrome-interacting factors (PIFs) are the pivotal direct downstream components of phytochromes. H2A.Z is a highly conserved histone variant regulating gene transcription, and its incorporation into nucleosomes is catalyzed by SWI2/SNF2-related 1 complex, in which SWI2/SNF2-related 1 complex subunit 6 (SWC6) and actin-related protein 6 (ARP6) serve as core subunits. Here, we show that PIFs physically interact with SWC6 in vitro and in vivo, leading to the disassociation of HY5 from SWC6. SWC6 and ARP6 regulate hypocotyl elongation partly through PIFs in red light. PIFs and SWC6 coregulate the expression of auxin-responsive genes such as IAA6, IAA19, IAA20, and IAA29 and repress H2A.Z deposition at IAA6 and IAA19 in red light. Based on previous studies and our findings, we propose that PIFs inhibit photomorphogenesis, at least in part, through repression of H2A.Z deposition at auxin-responsive genes mediated by the interactions of PIFs with SWC6 and promotion of their expression in red light.

Using malononitrile as the raw material, a novel synthesis route of 2-amino-4,6-dimethoxypyrimidine(ADM) was put forward, in order to solve the instability in first step reaction of industrial synthesis. The influence of reactant ratio, temperature and time on product quality and yield was explored. The results showed that ADM was successfully prepared through acetyl chloride route, the yield was higher than that of industrial production process, and the process stability was good, with the product purity over 99%. Therefore, the new synthesis route is suitable for industrial production.

基于广义惠更斯-菲涅耳原理、交叉谱密度函数,利用修正Von Karmon谱模型以及ITU-R颁布的大气折射率结构常数模型,推导出部分相干高斯-谢尔光束在大气湍流中传输时的束宽及角扩展表达式,讨论并对比斜程和水平两种传输方式下天顶角、传输距离、湍流强度、相干长度等参数对光束束宽与角扩展的影响,同时分别从相对束宽和相对角扩展的角度分析各种参数对于光束抑制湍流能力的影响,并给予相应的物理解释。结果表明:当天顶角小于π/3时,光束在斜程传输时的光束扩展和角扩展量接近于垂直传输,所受湍流影响很小。传输距离大于1 km时,束宽和相对束宽随传输距离的增加而明显增加。光束相干长度越大,光束所受湍流影响越大,而束宽及角扩展会随之减小。
