Genome-Wide Identification of GASA Gene Family in Ten Cucurbitaceae Species and Expression Analysis in Cucumber

Gibberellic acid-stimulated in Arabidopsis (GASA), a unique small molecular protein of plants, plays an essential role plant growth and development. The GASA family genes have been identified studied many plants. However, the identification gene Cucurbitaceae species has not reported yet. Therefore, this study, based on available genome information species, 10 including cucumber (Cucumis sativus), watermelon (Citrullus lanatus), melon melo), pumpkin (Cucurbita moschata), wax gourd (Benincasa hispida), sponge (Luffa cylindrica), bottle (Lagenaria siceraria), bitter (Momordica charantia), chayote (Sechium edule), snake (Trichosanthes anguina) were with bioinformatics methods. To understand functions genes, expression pattern analysis different tissues stress responses also analyzed. results showed that total 114 which divided into three subfamilies. Synteny among cucumber, rice nine colinear 12 six genes. cis-acting elements implied contained cis-elements associated hormone response. Tissue-specific revealed only CsaV3_2G029490 was lowly or expressed all tissues, CsaV3_3G041480 highly other seven tissue-specific patterns. Furthermore, exhibited degrees regulatory response under GA, abiotic biotic stresses. Two CsaV3_3G042060 CsaV3_3G041480, differentially multiple stresses, indicated these two play important roles development cucumber.
