“…Metal pollution is a tremendous problem faced by the local government in southern Jiangxi Province.Molybdenum and cadmium are the main pollutants in the tailings in the process of mining, which pose hazardously threats to animals and public health. Heat shock proteins are molecular chaperones that are involved in many normal cellular processes and stress responses [16]. HSPs represent a highly conserved class of cytoprotective proteins specifically induced at the cellular level in response to one of several environmental stressors and protect cells against environmental stress [17][18][19].…”

Cadmium (Cd) and high dietary intake of molybdenum (Mo) can cause multiple-organ injury in animals, but the co-induced toxicity of Mo and Cd to spleen in ducks is not well understood. The aim of this study was to investigate the co-induced effects of Mo and Cd on the mRNA expression levels of inflammatory cytokines and heat shock proteins (HSPs) in duck spleens. Two hundred forty healthy 11-day-old ducks were randomly divided into six groups and treated with a commercial diet containing Mo or/and Cd. After being treated with Mo or/and Cd for 30, 60, 90, and 120 days, the mRNA expression levels of nuclear factor-kappa B (NF-κB), tumor necrosis factor-α (TNF-α), cyclooxygenase-2 (COX-2), HSP60, HSP70, and HSP90 were examined in duck spleens. Histopathology was examined in duck spleens at 120 days. The results indicated that the mRNA expression levels of HSPs were significantly upregulated in the co-induced groups (P < 0.01), while these decreased in the high dietary intake of Mo combined with Cd group at 120 days. Exposure to Mo or/and Cd upregulated the mRNA expression levels of NF-κB, COX-2, and TNF-α in the combination groups (P < 0.01). Furthermore, severe congestion, bleeding, splenic corpuscle structure fuzzy, wall thickness of sheath artery thickening, and oxyhematin were observed in the spleens of combination groups. Meanwhile, the organizational structure damage of the combined groups was more severe than that of the other groups. These results suggested that exposure to Mo or/and Cd might lead to tissue damage, and high expression of HSPs and inflammatory cytokines may play a role in the resistance of spleen toxicity induced by Mo or/and Cd. Interaction of Mo and Cd may have a synergistic effect on spleen toxicity.

“…They were mainly found in the inner parts of the cell, membranes, and organelles. When other studies in the literature were examined, it was found that Hsp families were mostly located in intracellular parts in eucalyptus (Çelik Altunoğlu, 2016) and poplar (Zhang et al, 2015;Yer et al, 2016;Yer et al, 2018). The results for watermelon Hsp proteins have parallels with the results of these studies.…”

“…In the ClasHsp, ClaHsp40, and ClaHsp70 families, exonsintrons were approximately equal, while very few introns were detected in ClaHsp100 and no introns were observed in the ClaHsp60 and ClaHsp90 families. When the other studies were examined, it was seen that the exon structure predominated in the sHsp, Hsp70, and Hsp100 genes of the Hsp families in the A. thaliana genome (Zhang et al, 2015). When the Hsp70 family in the eucalyptus genome was examined, it was found that there were an approximately equal number of exon-intron structures as in the watermelon Hsp70 family (Çelik Altunoğlu, 2016a).…”

Heat shock protein (Hsp) gene family members in the watermelon genome were identified and characterized by bioinformatics analysis. In addition, expression profiles of genes under combined drought and heat stress conditions were experimentally analyzed. In the watermelon genome, 39 genes belonging to the sHsp family, 101 genes belonging to the Hsp40 family, 23 genes belonging to the Hsp60 family, 12 genes belonging to the Hsp70 family, 6 genes belonging to the Hsp90 family, and 102 genes belonging to the Hsp100 family were found. It was also observed that the proteins in the same cluster in the phylogenetic trees had similar motif patterns. When the estimated 3-dimensional structures of the Hsp proteins were examined, it was determined that the α-helical structure was dominant in almost all families. The most orthologous relationship appeared to be between watermelon, soybean, and poplar in the ClaHsp gene families. For tissue-specific gene expression analysis under combined stress conditions, expression analysis of one representative Hsp gene each from root, stem, leaf, and shoot tissues was performed by real-time PCR. A significant increase was detected usually at 30 min in almost all tissues. This study provides extensive information for watermelon Hsps, and can enhance our knowledge about the relationships between Hsp genes and combined stresses.

“…With the complement of genome DNA sequencing project, Hsf family members had been identified in more than 20 plant species at genome-wide scale [7], including Oryza sativa L. [8], Pyrus bretschneideri [13], Sorghum bicolor [14] and Populus [15]. The maximum of Hsf genes among monocots is 56 which was identified in wheat, while the maximum of Hsf genes among dicots were found in soybean [4].…”

Background：Heat shock transcription factors (Hsfs) take part in many physiological and biochemical pathways in plants by regulating the expression of various stress-responsive genes, such as heat shock proteins (Hsps). With the development of rice genome re-sequencing projects, some researches had been carried out to identify Hsf gene family members in rice at the whole genomic scale. However, Hsfs in cultivated and wild rice genomes has not been fully studied and compared, although genetic diversity in cultivated rice is limited compared to wild rice. Results：In this research work, Hsfs genes were screened and evolutionally compared in the genomes of 6 wild rice and 1 cultivated rice varieties, including O. barthii, O. glumaepatula, O. meridionalis, O. nivara, O. punctate, O. rufipogon and O. sativa & Nipponbare. Total 22, 23, 24, 24, 25, 25 and 25 Hsf genes were identified in the tested 7 rice genomes, respectively. The different number of Hsf genes between wild and cultivated rice genotypes was due to dispersed duplication and whole genome duplication (WGD) events, reversely contributed to different stress-tolerant ability between wild and cultivated rice. The evolutional analysis on the Hsf genes confirmed that O. rufipogon was the immediate ancestral progenitors of O. sativa. The expression profile of Hsf genes in Nipponbare and O. rufipogon under different stage of salinity stress showed that 4 root Hsf genes, including HsfA3a, HsfA4d, HsfC2a and HsfC2b, were simultaneously up-regulated by salinity stress in cultivated rice and its ancestral progenitor, implying that these 4 Hsf genes played conserved roles in rice in response to salinity stress. However, a substantial number of Hsf genes were exclusively regulated only in Oryza rufipogon rice seedling, suggesting that some of genuine salinity stress tolerance genes might be missing in cultivated rice. Conclusion：The results of this study would give insight into the evolution and function of Hsf gene members in rice, and hint to the use of wild relative genes to improve rice performance.
