How does jasmonate signaling enable plants to adapt and survive?
Jasmonates (JAs) are a class of plant hormones that play essential roles in response to tissue wounding. They act on gene expression to slow down growth and to redirect metabolism towards producing defense molecules and repairing damage.
What are JAZ proteins?
Members of the family of JASMONATE ZIM-DOMAIN (JAZ) proteins are key regulators of the jasmonate (JA) hormonal response. The 12-member family is characterized by three conserved domains, an N-terminal domain, a TIFY-containing ZINC-FINGER EXPRESSED IN INFLORESCENCE MERISTEM domain, and a C-terminal Jas domain.
What is the role of salicylic acid in plant defense?
Highlights. Salicylic acid (SA) serves as a key hormone in plant innate immunity, including resistance in both local and systemic tissue upon biotic attacks, hypersensitive responses, and cell death.
How does acetylsalicylic acid affect plant growth?
Theory Behind Aspirin for Plant Growth The component helps boost the plant’s immune system, just like it does for us. A diluted solution of aspirin water for plants provides accelerated germination and some resistance to disease and pests. Aspirin in vegetable gardens has been shown to increase plant size and yield.
How does salicylic acid affect plant growth?
Salicylic acid increases the plant’s response to tolerance and resistance to various diseases affecting plants as it is found that increasing its internal concentration activates the protective role of pathogenic pathogens [6].
What is a natural source of salicylic acid?
White willow (Salix alba) is a natural source of salicylic acid.
What is the function of jasmonate signaling network in plant cells?

What is the opr3-independent pathway for jasmonate synthesis?
Chini A., Monte I., Zamarreño A.M., Hamberg M., Lassueur S., Reymond P., Weiss S., Stintzi A., Schaller A., Porzel A., et al. An OPR3-independent pathway uses 4,5-didehydrojasmonate for jasmonate synthesis.
What do we know about the JA signaling pathway?
Lipid-derived jasmonates (JAs) play a crucial role in a variety of plant development and defense mechanisms. In recent years, significant progress has been made toward understanding the JA signaling pathway.
What is the source of jasmonate?
Most jasmonates originate from the oxidation of linolenic acid (18:3) in a biosynthetic pathway analogous to the synthesis of animal prostaglandins from arachidonate 3, 9. The chloroplast membrane is a source for 18:3, which is converted in three steps to 12-oxophytodienoic acid (OPDA) in this organelle.
