Leaf senescence in plants is a coordinated process that involves remobilization of nutrients from senescing leaves to sink tissues. The molecular events associated with nutrient remobilization are however not well understood. In this study the tobacco system with a source-sink relationship between differen...
To extend the shelf life of freshly harvested vegetables and cut flowers, a maize homeobox gene Knotted1 ( kn1 ) was placed under the control of a wound-inducible promoter win3.12 from hybrid poplar ( Populus trichocarpa × P. deltoides ) and introduced into tobacco plants ( Nicotiana tabacum...
Leaf senescence is a crucial trait that has a significant impact on crop quality and yield. Previous studies have demonstrated that light is a key factor in modulating the senescence process. However, the precise mechanism by which plants sense light and control senescence remains largely unknown, ...
Molecular Aspect of Leaf Senescence Senescence is the last stage of leaf development and one type of programmed cell death that occurs in plants. The relationships among senescence programs t... E Himelblau,B Quirino,YS Noh,... - 《Trends in Plant Science》 被引量: 1205发表: 2000年 Molecu...
A knowledge of how chloroplast to nucleus signalling is altered during senescence, particularly in relation to redox and hormone signalling pathways, will provide novel insights that can be incorporated into breeding strategies aimed at enhancing productivity by prolonging the lifespan of leaves. 展开 ...
Leaf is an important photosynthetic organ in rice, and its senescence is initiated by the endogenous genetic and developmental signals and the external environmental stress. Regulation of leaf senescence is a very complicated and delicate process in plants. NAD (nicotinamide adenine dinucleotide), a co...
Senescence is an important developmental process that leads to the cell death through highly regulated genetically controlled processes in plants. Biotic and abiotic Oxidative stresses can also artificially induce senescence and increase the production of reactive oxygen species (ROS) specifically in chloropl...
The sequence of events and the signals that regulate the remobilization of nitrogen (N) reserves during senescence induced by N starvation were studied in leaf 3, the last fully expanded leaf, in 17-day-old wheat ( Triticum aestivum L.) plants. The first event observed was a rapid decrease...
