In plants, excessive water loss causes drought stress and induces early senescence. In this study, we isolated a rice (Oryza sativa) mutant, designated as early senescence1 (es1), which exhibits early leaf senescence. The es1-1 leaves undergo water loss at the seedling stage (as reflected by...
Plants have developed sophisticated gene networks of ROS generation and scavenging systems. However, ROS regulation is still poorly understood. Here, we report that mutations in the Arabidopsis CPR5/OLD1 gene may cause early senescence through deregulation of the cellular redox balance. Genetic ...
High temperature promotes early senescence in primary leaves of sunflower (Helianthus annuus L.) plants High temperature affects numerous biochemical and physiological traits in plants. Primary leaves of sunflower (Helianthus annuus L.) were collected from pl... DL Habap,DL Matal,MolinaE,... - ...
Senescence is the final stage of leaf growth and development. Many different physiological activities occur during this process. A comprehensive metabolomics analysis of tobacco middle leaves at 5 different developmental stages was implemented through mu
Leaf senescence is an internally programmed degeneration phase in the life span of leaf. During growth and development, plants have both stress-induced and age-related senescence. From seedling to maturity, leaves are the main source of photosynthesis. At maturity stage, leaf cells undergo drastic ...
This study used a rice leaf early senescence mutant (osled) and its wild type (WT) to compare their main phenotypic and agronomic traits at different growth stages as well as some physiological characteristics. The results showed the osled plants exhibited leaf early senescence initiating from ...
Programmed cell death: A way of life for plants. Highlights a few examples of programmed cell death in plants. Mechanism and function of the process in plants; Two distinct processes of senescence in plan... Greenberg,Jean,T. - 《Proceedings of the National Academy of Sciences of the United...
When entering the booting stage, early senescence was apparent, and the leaves exhibited chlorosis. At the late stage of flowering, whole mutant leaves became tan, as if they had been Discussion Many LMMs have been identified in plants, and these have been widely applied to the study of key...
ERF, a member of the APETALA2/ERF family, is a plant-specific TF with a variety of functions, including biotic and abiotic stress responses, as well as the regulation of hormone biosynthesis and fruit development, ripening, and senescence [40,41,42]. Recent studies have confirmed the involvem...
