“…Meanwhile, in nutrient starvations conditions SnRK1.1 phosphorylates ATG1 and ATG6 to induce autophagy ( Chen et al, 2017 ; Pu et al, 2017 ; Soto-Burgos and Bassham, 2017 ; Huang et al, 2019 ). Moreover, PI3K interacts with V-ATPase (vacuolar H + -ATPase) to activate stomatal acidification, which leads to stomatal closure and delayed leaf senescence, and also alleviates leaf senescence under jasmonate treatment ( Liu et al, 2016a , b ).…”

Leaf senescence is an evolutionarily acquired process and it is critical for plant fitness. During senescence, macromolecules and nutrients are disassembled and relocated to actively growing organs. Plant leaf senescence process can be triggered by developmental cues and environmental factors, proper regulation of this process is essential to improve crop yield. Protein kinases are enzymes that modify their substrates activities by changing the conformation, stability, and localization of those proteins, to play a crucial role in the leaf senescence process. Impressive progress has been made in understanding the role of different protein kinases in leaf senescence recently. This review focuses on the recent progresses in plant leaf senescence-related kinases. We summarize the current understanding of the function of kinases on senescence signal perception and transduction, to help us better understand how the orderly senescence degeneration process is regulated by kinases, and how the kinase functions in the intricate integration of environmental signals and leaf age information.

“…In addition, PI3K is involved in regulating phytohormone-mediated cellular activities. Examples include the promotion of ethylene biosynthesis to accelerate flower senescence in transgenic Nicotiana tabacum [130], the regulation of GA-stimulated α-amylase secretion in barley (Hordeum vulgare) [131], and the delay of methyl JA (MeJA)-induced leaf senescence in Arabidopsis [132,133]. Ethylene, GA, and MeJA are all reported to play regulatory roles during salt stress [134][135][136][137].…”

High salinity threatens crop production by harming plants and interfering with their development. Plant cells respond to salt stress in various ways, all of which involve multiple components such as proteins, peptides, lipids, sugars, and phytohormones. Phospholipids, important components of bio-membranes, are small amphoteric molecular compounds. These have attracted significant attention in recent years due to the regulatory effect they have on cellular activity. Over the past few decades, genetic and biochemical analyses have partly revealed that phospholipids regulate salt stress response by participating in salt stress signal transduction. In this review, we summarize the generation and metabolism of phospholipid phosphatidic acid (PA), phosphoinositides (PIs), phosphatidylserine (PS), phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylglycerol (PG), as well as the regulatory role each phospholipid plays in the salt stress response. We also discuss the possible regulatory role based on how they act during other cellular activities.
