Inferred from mutant phenotype i. Ref.8. "Chloroplast small heat shock protein HSP21 interacts with plastid nucleoid protein pTAC5 and is essential for chloroplast development in Arabidopsis under heat stress." Zhong L., Zhou W., Wang H., Ding S., Lu Q., Wen X., Peng L., Zhang L., Lu C. Description. Encodes Hsp21, a chloroplast located small heat shock protein.

PDF | Acquired tolerance to heat stress is an increased resistance to elevated temperature following a prior exposure to heat. The maintenance of | Find, read and cite all the research you need 2019-12-17 · Arabidopsis seedlings were treated with high light (HL: 1,200 μmol m −2 s −1, leaf temperature: 22°C) for 0.5, 6, 12, 24, 48, and 72 h with corresponding growth light (GL: 60 μmol m −2 s −1, leaf temperature: 22°C) treatments as control. Here we show that Arabidopsis HSP21, a plastidial small heat shock protein that rapidly accumulates after heat stress and remains abundant during the thermomemory phase, is a crucial component of thermomemory. Sustained memory requires that HSP21 levels remain high.

Plant species such as the model organism Arabidopsis thaliana, have Description : Encodes Hsp21, a chloroplast located small heat shock protein. A structure model of Hsp21, obtained by homology modeling, single-particle electron microscopy, and lysine-specific chemical crosslinking, shows that the Hsp21 subunits are arranged in two hexameric discs, rotated by 25 degree in relation to each other. 2016-08-26 Using transgenic Arabidopsis thaliana plants that overexpress Hsp21 I found that Hsp21 improves the plant performance during concomitant heat and light stress and that Hsp21 undergoes conformational changes during stress. LifeSpan BioSciences currently sells 2 antibodies specific for Arabidopsis thaliana HSP21. and its downstream target gene HSP21 in Arabidopsis (Yu et al., 2012). In Arabidopsis, the involvement of tetrapyrrole in retrograde signaling was identified in gen-ome-uncoupled mutants (gun) that continuously express photosynthesis-associated nuclear genes (PhANG), includ-ing the light-harvesting complex of photosystem II (Lhcbs) Physiological evidence suggests that the small chloroplast heat‐shock protein 21 (HSP21) is involved in plant thermotolerance, but the molecular mechanism of its action remains largely unknown. Here, we have provided genetic and biochemical evidence that HSP21 is activated by the GUN5‐dependent retrograde signaling pathway, and stabilizes PSII by Recombinantly expressed Hsp21 from Arabidopsis thaliana (sequence as in UniProtKB P31170 with a start methionine replacing the first 44 amino acids, which are the transit sequence not part of the mature protein within the chloroplast47), and non‐dodecameric mutational variant Hsp21 V81A, were expressed and purified as previously described.21 Hsp21 protein labeled with 15N was obtained by growing the … Loss-of-function analyses in Arabidopsis indicate that HSP21 is essential for chloroplast development under heat stress through maintaining PEP function.
