Since 1999, various forward-and reverse-genetic approaches have uncovered nearly 200
genes required for symbiotic nitrogen fixation (SNF) in legumes. These discoveries …

Senescence is an age-dependent process, ultimately leading to plant death, that in annual
crop plants overlaps with the reproductive stage of development. Research on the molecular …

The central dogma (CD) of molecular biology is the transfer of genetic information from DNA
to RNA to protein. Major CD processes governing genetic flow include the cell cycle, DNA …

Developmental age is a strong determinant of stress responses in plants. Differential
susceptibility to various environmental stresses is widely observed at both the organ and …

Leaf senescence represents the final stage of leaf growth and development, and its onset
and progression are strictly regulated; however, the underlying regulatory mechanisms …

During droughts, leaves are predicted to act as 'hydraulic fuses' by shedding when plants
reach critically low water potential (Ψplant), thereby slowing water loss, stabilizing Ψplant …

Reactive oxygen species (ROS) are unstable reactive molecules that are toxic to cells.
Regulation of ROS homeostasis is crucial to protect cells from dysfunction, senescence, and …

Leaf senescence–the coordinated, active process leading to the organized dismantling of
cellular components to remobilize resources–is a fundamental aspect of plant life. Its tight …

The study of senescence in plants is complicated by diverse levels of temporal and spatial
dynamics as well as the impact of external biotic and abiotic factors and crop plant …

In this study, field-grown wheat (Triticum aestivum L.) was treated with normal (Nn) and
excessive (Ne) levels of fertilizer N. Results showed that Ne depressed the activity of …
