Understanding these PGRs and their roles has given modern agriculture new tools to fight diseases and pests, reduce the build-up of resistance to fungicidal and insecticidal active ingredients and enhance crop tolerance to a wide range of abiotic stresses, such as wet, dry, cold and hot.

With the natural origin of the raw materials and the small particle size, we have ensured maximum absorption and accumulation of vital nutrients in stock, which contributes to the systemic action of the product. (panamin.bg)

Plant immunity to insect herbivores. (notulaebiologicae.ro)

Corynespora cassiicola , as a necrotrophic phytopathogenic ascomycetous fungus, can infect hundreds of species of plants and rarely causes human diseases. (biomedcentral.com)

The triggered immunity involves considerable increases in the endogenous levels of SA and its conjugates prior to the induction of pathogenesis-related (PR) proteins and the onset of local and systemic acquired resistance [ 8 ]. (researchsquare.com)
OsALD1 proteins predominantly localized at the chloroplast in the plant cells. (ppjonline.org)

Jim , you say that my hydroponic plants can become more disease resistant and recover from other diseases that are already attacking them? (plain2growsystems.com)

Reactive oxygen intermediates mediate a systemic signal network in the establishment of plant immunity. (springer.com)

To further elucidate temperature-resilient immunity, I measured SA hormone levels in representative accessions and found very low SA levels in both representative temperature-sensitive and temperature-resilient accessions. (wlu.ca)

The Antimicrobial Resistance (AMR) Challenge was a yearlong effort by the U.S. government to accelerate the fight against AMR. (cdc.gov)
Doing so will avoid unnecessary use of antibiotics, which leads to increased adverse effects of medication and facilitates the development of antimicrobial resistance. (medscape.com)

Salicylates are hormones found in almost all plants. (plain2growsystems.com)
compiles information on how recruitment of plant metabolites and hormones act as signals and regulators in AM symbiosis and may be therefore regarded as targets of plant breeding, also focusing on the variations in host response to AM symbiosis. (plantae.org)
Plant hormones are frequently modified by glycosylation, hydroxylation, methylation and other conjugations, and these modifications can alter the hormone's activity and stability (Wang et al. (plantae.org)

Regulatory non-coding RNAs: a new frontier in regulation of plant biology. (mabjournal.com)
WRKY transcription factors, as one of the largest transcription factor families, play important roles in regulation of many plant processes, including drought stress response. (biomedcentral.com)

The resistance to X. perforans race T3 in tomato can be classified into two types, hypersensitive response (HR) and field resistance. (frontiersin.org)

The WRKY70 transcription factor: a node of convergence for jasmonate-mediated and salicylate-mediated signals in plant defense. (notulaebiologicae.ro)

2019). Investigating UGT functions is enabled and facilitated by the availability of plant genome sequences and the development of large-scale methods for data-gathering and analysis. (plantae.org)

LSCs are highly proliferative cells that stimulate tumor initiation, migration, EMT, and drug resistance. (bvsalud.org)

The roles of reactive oxygen species in plant cells. (chinaagrisci.com)

We are interested in how local resistance and systemic acquired resistance are regulated in plants. (ubc.ca)

The first response of the plant in its struggle for survival due to abiotic and biotic stress is the production of one of the main phytohormones - silicic acid. (panamin.bg)

Induced systemic resistance by beneficial microbes. (nature.com)

The plant microbiota consists of a multitude of microorganisms that can affect plant health and fitness. (nature.com)
