“…Moreover, an sHSP influences pectin depolymerization in tomato fruit ripening [63]. In a proteome-wide study, eight HSP genes were associated with tomato fruit development and ripening [64], demonstrating that HSP genes indeed participate in tomato fruit ripening [65]. Stress is a well-known stimulus that triggers the induction of sHSPs [62].…”

Background In a previous study, the early ripening of Kyoho grape following H2O2 treatment was explored at the physiological level, but the mechanism by which H2O2 promotes ripening at the molecular level is unclear. To reveal the molecular mechanism, RNA-sequencing analysis was conducted on the different developmental stages of Kyoho berry treated with H2O2. Results In the comparison of treatment and control groups, 406 genes were up-regulated and 683 were down-regulated. Time course sequencing (TCseq) analysis showed that the expression patterns of most of the genes were similar between the treatment and control, except for some genes related to chlorophyll binding and photosynthesis. Differential expression analysis and the weighted gene co-expression network were used to screen significantly differentially expressed genes and hub genes associated with oxidative stress (heat shock protein, HSP), cell wall deacetylation (GDSL esterase/lipase, GDSL), cell wall degradation (xyloglucan endotransglucosylase/ hydrolase, XTH), and photosynthesis (chlorophyll a-b binding protein, CAB1). Gene expression was verified with RT-qPCR, and the results were largely consistent with those of RNA sequencing. Conclusions The RNA-sequencing analysis indicated that H2O2 treatment promoted the early ripening of Kyoho berry by affecting the expression levels of HSP, GDSL, XTH, and CAB1 and- photosynthesis- pathways.

“…This is especially problematic for the highly duplicated CI proteins (Table 1), although RNAi experiments have been performed. The RNAi of a CI sHSP in tomato was reported to decrease sucrose and fructose content of ripening fruits by an unknown mechanism (Zhang et al , 2018). Suppression of CI or CII sHSPs in A. thaliana by RNAi showed that these sHSPs were required for recovery from a severe heat stress (10 h at 45°C) and have independent functions (McLoughlin et al , 2016).…”

Plant small heat shock proteins – evolutionary and functional diversity

2020

Small heat shock proteins (sHSPs) are an ubiquitous protein family found in archaea, bacteria and eukaryotes. In plants, as in other organisms, sHSPs are upregulated by stress and are proposed to act as molecular chaperones to protect other proteins from stressinduced damage. sHSPs share an 'a-crystallin domain' with a b-sandwich structure and a diverse N-terminal domain. Although sHSPs are 12-25 kDa polypeptides, most assemble into oligomers with ≥ 12 subunits. Plant sHSPs are particularly diverse and numerous; some species have as many as 40 sHSPs. In angiosperms this diversity comprises ≥ 11 sHSP classes encoding proteins targeted to the cytosol, nucleus, endoplasmic reticulum, chloroplasts, mitochondria and peroxisomes. The sHSPs underwent a lineage-specific gene expansion, diversifying early in land plant evolution, potentially in response to stress in the terrestrial environment, and expanded again in seed plants and again in angiosperms. Understanding the structure and evolution of plant sHSPs has progressed, and a model for their chaperone activity has been proposed. However, how the chaperone model applies to diverse sHSPs and what processes sHSPs protect are far from understood. As more plant genomes and transcriptomes become available, it will be possible to explore theories of the evolutionary pressures driving sHSP diversification.

“…Their antistress functions are diverse (Gorovits et al, 2007) and various organisms, including plants, can also produce these types of response proteins under stress (Chivasa et al, 2006). In tomato ( Solanum lycopersicum ), sHSPs can regulate the changes in soluble sugar content in postharvest fruits and maintain the stable state of reactive oxygen species, thus improving the ability of tomato fruits to respond to stress (Zhang et al, 2018). However, the type of signalling pathways that sHSPs are involved in to facilitate resistance to stress in plants is still unknown.…”

Strawberry (Fragaria × ananassa) is an important economic plant widely cultivated all over the world (Giampieri et al., 2017).Anthracnose causes up to 80% of plant death in nurseries and over 50% of yield loss in strawberry fields (Sreenivasaprasad & Talhinhas, 2005). Three Colletotrichum species have been reported as causal agents of strawberry anthracnose: Colletotrichum gloeosporioides and Colletotrichum fragariae frequently infect strawberry leaves, stems, and roots, while Colletotrichum acutatum often causes strawberry fruit rot (Denoyes-Rothan et al., 2003;Peres et al., 2005). However, many studies have indicated that C. gloeosporioides is the most prevalent agent of strawberry anthracnose in China, whereas C. acutatum and C. fragariae cause anthracnose to a lesser extent (
