Summary: | Watermelon (
) as a crop with important economic value, is widely cultivated around the world. The heat shock protein 70 (HSP70) family in plant is indispensable under stress conditions. However, no comprehensive analysis of watermelon
family is reported to date. In this study, 12
genes were identified from watermelon, which were unevenly located in 7 out of 11 chromosomes and divided into three subfamilies. ClHSP70 proteins were predicted to be localized primarily in cytoplasm, chloroplast, and endoplasmic reticulum. Two pairs of segmental repeats and 1 pair of tandem repeats existed in
genes, and
underwent strong purification selection. There were many abscisic acid (ABA) and abiotic stress response elements in
promoters. Additionally, the transcriptional levels of
in roots, stems, true leaves, and cotyledons were also analyzed. Some of
genes were also strongly induced by ABA. Furthermore,
also had different degrees of response to drought and cold stress. The above data indicate that
may be participated in growth and development, signal transduction and abiotic stress response, laying a foundation for further analysis of the function of ClHSP70s in biological processes. |
