  • The use of synthetic oligonucleotides could shed light on the mechanism of stimulation of immunity by DNA, which might be a promising tool for crop protection and plant disease management," conclude Toum and colleagues. (botany.one)
  • To date, work on induction of plant systemic resistance has shown that inducing plant system resistance work has important implications for basic and applied research. (wikipedia.org)
  • Induction of immunity in A. thaliana by IMT504 and 2006 has similarities with that elicited by other MAMPs, such as flagellin, since both ssODNs promoted stomatal closure, inhibited root elongation and induced the transcription of defence genes. (botany.one)
  • As a positive regulator of plant immunity, E3 ligase SAUL1 is guarded by NLR protein SOC3. (ubc.ca)
  • This increased host vulnerability at higher temperatures is due to downregulated expression of CALMODULIN BINDING PROTEIN 60-LIKE G (CBP60g) and SYSTEMIC ACQUIRED RESISTANCE DEFICIENT 1 (SARD1), which encode master regulators of SA production. (wlu.ca)
  • Barbara was among the first plant scientists to use molecular biology-based approaches to understand evolutionary processes in plants, and she has worked to advance understanding of plant molecular systematics and population genetics. (aspb.org)

  • With its main components calcium and magnesium carbonate, it enables the release of CO2 to accelerate photosynthesis and to have a beneficial effect on the pH level of plants and soil. (panamin.bg)
  • Silicic acid - Si(OH)4, is taken from the soil through the root system and transported through the xylem to the plant parts, where it condenses in the form of silica gel. (panamin.bg)
  • Terpenes in particular play an important role in plant immuno-defense systems, acting both directly as a primary defense and indirectly as communication molecules as we will see later. (cannabissciencetech.com)
  • Unlike animals, plants are immobile but do have the capacity to send warning signals from one part of the plant to another, or even from one plant to another through gaseous cues and molecules (Figure 2). (omexcanada.com)
  • To produce 1 molecule of CO2, the plant consumes 100 molecules of water. (panamin.bg)
  • Leading the study was Michael Kolomiets , Ph.D., professor of plant pathology and microbiology at Texas A&M University's College of Agriculture and Life Sciences. (farm-d.org)
  • OsALD1 mRNA was strongly transcribed in the infected leaves of rice plants by Magnaporthe oryzae , the rice blast fungus. (ppjonline.org)
  • Yes, scientists are now studying whether or not they can turn edible plants into mRNA vaccine factories. (mymedicalfreedom.org)
  • Meaning, they actually use the cytoplasm in the plant to produce the mRNA ," Kingston explained. (mymedicalfreedom.org)
  • In simpler terms, Kingston explained, "they're basically putting the mRNA into the plants. (mymedicalfreedom.org)

  • There has been a lot of work on immunity in mammals, no doubt because humans are mammals. (botany.one)
  • Limited information is available on other systemic effects reported in humans and is associated with high-level benzene exposure. (cdc.gov)
  • 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)
  • In this work we found that ssODNs IMT504 and 2006, previously shown to activate immunity in mammalian cells, can protect A. thaliana from Botrytis cinerea and from Pst DC3000, but not from crucifer-infecting tobacco mosaic virus (TMV-Cg). (botany.one)
  • If beneficial fungi - which often reside on roots for the life of a plant - cause plants to produce jasmonic acid all the time, he said, "I was always wondering, how is it possible that the fungi also promote growth? (farm-d.org)
