| Summary: | Leucine-Rich Repeats Extensins (LRX) are a type of cell wall protein that participate in the formation of the plant cell wall and play a crucial role in plant growth and development. However, the study of LRX genes in Cucurbitaceae has not been reported. Here, 40 LRX genes were identified from seven cucurbit species in the Cucurbitaceae database, including cucumber (Cucumis sativus), wax gourd (Benincasa hispida), watermelon (Citrullus lanatus), pumpkin (Cucurbita maxima), moschata pumpkin (Cucurbita moschata), bottle gourd (Lagenaria siceraria), and melon (Cucumis melon). These LRX genes were divided into two subfamilies: LRX, controlling vegetative growth, and PEX, controlling reproductive growth. The gene structure, domain, and motif were relatively conserved, indicating that genes within each subfamily have similar functions. The differences in the number of LRX genes among the seven cucurbit species indicate the presence of gene loss or duplication events during evolution. Analysis of cis-regulatory elements showed that these LRX genes may be involved in plant growth and development, phytohormone response, and biotic and abiotic stress responses. In addition, the expression pattern of CsLRX genes in different tissues of cucumber and its expression analysis under salt stress and drought stress were detected by real-time quantitative PCR (qRT-PCR). The results showed that CsLRX genes showed organ-specific expression pattern in cucumber and responded to adversity stress. In summary, the results of the study provide a reference for further understanding the role of these genes in cell wall formation and the growth and development of Cucurbitaceae crops. |
