JAs derive from polyunsaturated fatty acids, such as α-linolenic acid , through a complex series of metabolic reactions that take place sequentially in different compartments of the plant cell (e.g., chloroplast, peroxisome, cytosol). (botany.one)
Unlike our glandular bodies, each cell within a plant is able to produce its own hormones. (thedailygarden.us)
Here the central vacuoles volume expands as water enters the plant cell. (hightimes.com)
29. ………………… stimulates cell division in plants by inducing mitosis in root and shoot cells. (icseboards.com)
In vitro cultures provide several advantages when the plant cell tolerance to toxic elements is to be examined in experimental studies ( [12] , [9] ). (sisef.it)

I favor bioidenticals as they're identical to our own hormones. (damiva.com)
Climate change-related warming-induced shifts in leaf chemical traits favor nutrition of the specialist herbivore Battus polydamas archidamas. (mpg.de)

ABA is a stress hormone perceived by the soluble receptor PYR1 (encoded by Pyrabactin resistance 1 ) and its related PYR1- like and R egulatory C omponent of ABA R ecepto r proteins ( PYL/RCAR , PYLs for simplicity) 18 . (nature.com)
A common mechanism for plant hormone action is the breakdown or activation of DNA transcription proteins. (hightimes.com)

Plant hormones are chemical substances produced by plants and found in low concentrations in plants. (edumarz.com)

Other plant products may be used for the manufacture of commercially important rubber or biofuel. (wikipedia.org)
Name three important plant hormones. (getrevising.co.uk)
In these networks, phytohormones also play an important role. (nhbs.com)
Since we all want our plants to grow, phytohormones are pretty important. (thedailygarden.us)
Information regarding root growth and root canopy ratio is important as it gives us an understanding of the relationship between the aerial and subterranean parts of the plant, how they compete, and finally, offers us the possibility to ponder on cultural practices. (preprints.org)

These factors are both intrinsic (internal) and extrinsic (external) to the plant. (unseenpassage.com)

Increasing concentrations of Cd (0, 5, 50, and 250 µM) and Cu (0, 5, 50, 250 and 500 µM) were separately applied to evaluate the effect of metals on their absorption and accumulation in downy oak plants. (sisef.it)
Therefore, selection and/or breeding of suitable plant genotypes based on biomass production, accumulation potential, root traits, growth rate, environmental suitability and metal resilience are required for their use in the remediation of heavy metal contamination ( [29] ). (sisef.it)

This metabolic process has been partially described as a chemical, biochemical, enzymatic and genomic events. (floram.org)
