在自然界中,种子在土壤中萌发后,将迅速穿破土层获取光照进行光合作用等生理活动。此时,幼苗下胚轴或茎迅速伸长,双子叶植物的子叶闭合并形成弯钩,以克服出土的压力。幼苗出土见光后,下胚轴或茎的伸长受到抑制、弯钩打开、子叶张开、叶绿体发育完善并合成叶绿素,进行光合作用。土壤下的暗形态建成和见光后的光形态建成是大多数种子植物所必须经历的生长发育过程。
2024年1月24日,万建民院士领衔的南京农业大学和中国农业科学院作物科学研究所的科研团队合作在国际著名期刊The plant cell在线发表了题为“Rice LIKE EARLY STARVATION1 cooperates with FLOURY ENDOSPERM6 to modulate starch biosynthesis and endosperm development ”的研究...
Hydrogel is a macromolecular gel constructed of a network of cross-linked polymer chains. Hydrogels are class of materials that can be tuned toward the subjected stimuli and can be modified to imitate...
Forest production is strongly dependent on nutrient uptake; however, sustainable management of intensively managed plantations requires an improved understanding of this relationship when fertilizatio...
The Department of Energy, in conjunction with Massachusetts Institute of Technology and Texas A&M University, will conduct a biweekly webinar series aimed at providing a broad overview of nuclear wast...
A new type of cold spray coating, made from the metal tantalum and applied to the plasma-facing steel walls of fusion reactors, could lead to efficient, compact fusion reactors that are easy to repair...
Root development is important for normal plant growth and nutrient absorption. Studies have revealed the involvement of various factors in this complex process, improving our understanding of the rele...
RNA turnover is a general process that maintains appropriate mRNA abundance at the posttranscriptional level. Although long thought to be antagonistic to translation, discovery of the 5? to 3? cotrans...
The urgent need to replace fossil resource-based products is considerably increasing in the past few years, resulting in the search for more sustainable materials, with the aim of reducing the wastes ...
Thirty years of research have revealed the fundamental role of the ubiquitin–proteasome system in diverse aspects of cellular regulation in eukaryotes. The ubiquitin–protein ligases or E3s are central...

Background: As one of the most important modified products of rosin, rosin glyceride was widely used in many aspects. However, the preparation of rosin glyceride is always unfriendly due to the use of...
Wildland fires have been a rising problem on the worldwide level, generating ecological and economic losses. Specifically, between wildland fire types, uncontrolled fires are critical due to the poten...
Paclitaxel (PTX) is a complex diterpenoid anticancer drug whose separation from yew biomass poses a significant challenge. In this study, a new stationary phase comprising hydrogenated rosin (β-acrylo...
The purpose of this work is the synthesis of adipic acid ester and the study of the possibility of its use as a PVC plasticizer. The resulting butyl phenoxyethyl adipate was characterized by Fourier-t...
