Both chitinase activity and protein level were found to be induced during senescence, as was the level of two other proteins immunologically related to β‐1,3‐glucanase and P4 pathogenesis‐related proteins of citrus and tomato, respectively. A high correlation between the advancement of senescence...
Leaf senescence, the last stage of leaf development, is a type of postmitotic senescence and is characterized by the functional transition from nutrient assimilation to nutrient remobilization which is essential for plants’ fitness. The initiation and progression of leaf senescence are regulated by a...
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
As the last stage of leaf development, the initiation and progression of leaf senescence are tightly controlled by genetic programing and coordinated by both internal and external factors. Plant hormone is one of the important internal factors that affect leaf senescence. It is widely acknowledged tha...
The influence of NaCl on senescence-related parameters (protein and chlorophyll concentrations, membrane permeability and chlorophyll fluorescence) was investigated in young and old leaves of five rice cultivars differing in salt resistance. NaCl hastened the naturally-occurring senescence of rice leaves whi...
Protein degradation and nitrogen remobilization during leaf senescence Leaf senescence, a type of programmed cell death, is a complex and highly regulated process that involves the degradation of macromolecules, including prot... J Liu,HW Yun,JJ Yang,... - 《Journal of Plant Biology》 被引量: ...
metabolic processes and catalytic activity, the numbers of SAGs were significantly larger than those of SDGs, suggesting an enhancement of catalytic activities during leaf senescence. SAGs related to protein tagging activities were enriched in ML and LL but not in UL leaves. Protein tagging could be...
WRKY53, a node of multiple layer during senescence, is involved in the onset of leaf senescence (Zentgraf and Doll, 2019). A mitogen-activated protein kinase kinase kinase MEKK1, a DNA binding protein, could bind to the promoter of WRKY53. In addition, it also interacts with WRKY53 and ...
rate. Besides, the mutant showed higher resistance toXanthomonas oryzaepv.Oryzaethan its wild type, coupled with up-regulation of four pathogenesis-related marker genes. Taken together, our results highlight Fd-GOGAT is associated with the regulation of leaf senescence and defense responses in rice....
The Remobilization of Nitrogen Related to Leaf Growth and Senescence in Rice Plants (Oryza sativa L.) Rice plants (Oryzae sativa L.) grown in a nutrient solution were fed with (15NH4)2SO4 during the 5 days of their young panicle formation.At the end of that... M Tadahiko,O Koji - ...
