Summary
Jasmonate hormones regulate plant processes, with recent discoveries highlighting plasma membrane proteins crucial for JA transport, defense, and endocytosis. This review explores these vital PM-localized proteins in plant signaling.
Area of Science:
- Plant biology
- Molecular biology
- Biochemistry
Background:
- Jasmonate (JA) is a critical plant hormone regulating development and stress responses.
- JA biosynthesis and signaling primarily occur in organelles, not the plasma membrane (PM).
- Emerging evidence links PM proteins to the JA pathway.
Purpose of the Study:
- To review recent advancements in understanding the role of PM-localized proteins in the JA pathway.
- To summarize the functions of these proteins in JA transport, defense, and endocytosis.
- To highlight the significance of the PM in JA signaling.
Main Methods:
- Literature review of recent scientific publications.
- Analysis of studies reporting PM proteins involved in JA signaling.
- Synthesis of findings on protein functions in JA transportation, defense, and endocytosis.
Main Results:
- Several PM proteins are identified as key players in JA-related processes.
- These proteins facilitate JA transportation across the plasma membrane.
- PM proteins are involved in JA-mediated defense responses and endocytosis.
Conclusions:
- The plasma membrane is an important site for JA signaling.
- PM-localized proteins play diverse and critical roles in JA hormone action.
- Further research into these PM proteins will enhance understanding of plant hormone regulation.

01:25cAMP-dependent Protein Kinase Pathways
7.2K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

5.9K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

01:07MAPK Signaling Cascades
6.9K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

01:20The JAK-STAT Signaling Pathway
10.0K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which...
