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 …

Leaves provide energy for plants, and consequently for animals, through photosynthesis.
Despite their important functions, plant leaf developmental processes and their underlying …

The phytohormone cytokinin was originally discovered as a regulator of cell division. Later, it
was described to be involved in regulating numerous processes in plant growth and …

Leaf senescence is a natural phenomenon that occurs during the aging process of plants
and is influenced by various internal and external factors. These factors encompass plant …

Since its first identification in the 1950s as a regulator of cell division, cytokinin has been
linked to many physiological processes in plants, spanning growth and development and …

The cytokinins have been implicated in many facets of plant growth and development
including cell division and differentiation, shoot and root growth, apical dominance …

Cytokinins (CKs) are key phytohormones that not only regulate plant growth and
development but also mediate plant tolerance to drought stress. Recent advances in …

Among different abiotic stresses, drought stress is the leading cause of impaired plant
growth and low productivity worldwide. It is therefore essential to understand the process of …

Leaf senescence, the final stage of leaf development, is one of the adaptive mechanisms
formed by plants over a long period of evolution. Leaf senescence is accompanied by …

In this review, we summarize the results of experiments that lead to altered levels of
phytohormones in transgenic plants to improve plant productivity. The available data …
