A newly developed on-line visual ferrograph(OLVF) gives a new way for engine wear state monitoring. However, the reliability of on-line wear debris image processing is challenged in both monitoring ship engines and the Caterpillar bench test, which wer

重力反应是植物对环境的一种适应现象。生长素参与植物环境适应与发育调控的过程,重力反应过程的核心之一是在重力反应器官形成生长素的浓度梯度,诱导下游基因的差异表达。生长素的合成、代谢、极性运输及信号转导在此过程中发挥了关键作用。该文以拟南芥和水稻的研究为基础,综述了近几年对生长素调控植株重力反应的分子机理的研究进展,并对该领域未来的研究进行展望。
生长素参与植物生长发育的各个阶段,如胚胎发生、发育,营养器官发生与形态建成,极性与轴向的建立,维管组织分化,生殖器官的发育等。虽然生长素在植物的各组织器官和细胞中发挥着重要的作用,植物内源生长素的生物合成却是在特异的组织——细胞快速分裂的幼嫩组织中完成的,然后通过韧皮部或受严格控制的细胞—细胞运输系统运送至植物各个部分。生长素的极性运输导致其积累在某些局部组织和细胞内,形成特定梯度分布。生长素对植
水下绞车是进行海洋环境监测和立体剖面测量的重要设备,介绍了水下绞车的国内外发展现状,提供了一种无人值守式水下绞车装置的结构及相关参数计算。
Phytohormone salicylic acid (SA) plays important roles in plant responses to environmental stress. However, knowledge about the molecular mechanisms for SA affecting the stomatal movements is limited.
Suaeda salsa L. is a halophytic species that is well adapted to high salinity. In order to understand its salt tolerance mechanism, we examined the growth and vacuolar H+-ATPase (V-ATPase) response to
Asr (abscisic acid, stress, ripening induced) genes are typically upregulated by a wide range of factors, including drought, cold, salt, abscisic acid (ABA) and injury; in addition to plant responses
Magnetic parameters and element contents were determined in core NJ008 collected from the uppermost ca. 40 cm in a steel company in southwest Nanjing. The results showed that magnetic susceptibility (
The influence of soil moisture on Asian monsoon simulation/prediction was less studied, partly due to a lack of available and reliable soil moisture datasets. In this study, we firstly compare several
