Recently it has become clear that the sHSPs are polydisperse, meaning that more than one oligomeric state is found (Baldwin, 2011). HSP21 is a target of HsfA2 (ref. 52), a heat-inducible transcription factor that plays a crucial role for setting the thermomemory in Arabidopsis 25. It is also upregulated by HsfA1a/b 61 , indicating that heat-induced expression of HSP21 is under the control of multiple heat-associated transcription factors.

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.

The chloroplast-localized sHsp, named Hsp21 with reference to its monomeric size, has an N-terminal region that is some 40 amino acids longer compared to the cytosolic sHsps, and increases plant stress tolerance as shown by Arabidopsis thaliana plants which overexpress Hsp21.

Plant species such as the model organism Arabidopsis thaliana, have A Chloroplast Localized Small Heat Shock Protein, Hsp21. Importance of Hsp21 in stress protection of transgenic Arabidopsis thaliana, recombinant expression and characterization of oxidation-dependent conformational changes.

The Arabidopsis proteins RAR1 and SGT1 are required for the action of many R proteins, and display some structural similarity to HSP90 co‐chaperones. Each associates with HSP90 in plant cells. Our data suggest that (i) RPM1 is an HSP90 client protein; and (ii) RAR1 and SGT1 may function independently as HSP90 cofactors.

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. 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.

Here, we used a set of Arabidopsis mutants such as salicylic acid (SA) signaling mutants nonexpressor of pathogenesis-related gene 1 (npr1-1 and npr1-5) and heat-shock proteins (HSPs) mutants (hsp21 and hsp70-1) to understand the requirement of SA signaling and HSPs in elevated CO2-induced HS tolerance. We have also analyzed isolated Arabidopsis HSP21 protein, purified in large amounts as recombinant protein after overexpression in E. coli.

HSP21 and pTAC5 are required for chloroplast development under heat stress by maintaining plastid-encoded RNA polymerase function. Present a structure model of Arabidopsis thaliana Hsp21, obtained by homology modeling, single-particle electron microscopy, and lysine-specific chemical crosslinking.

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. We show that an Arabidopsis thaliana knockout mutant of HSP21 had an ivory phenotype under heat stress. Quantitative real-time RT-PCR, run-on transcription, RNA gel blot, and polysome association analyses demonstrated that HSP21 is involved in plastid- encoded RNA polymerase (PEP)–dependent transcription.
