| description | PLAC8 is a cysteine-rich protein that serves as a central mediator of tumor evolution in mammals. PLAC8 motif-containing proteins widely distribute in fungi, algae, higher plants and animals that have been described to be implicated in fruit size, cell number and the transport of heavy metals such as cadmium or zinc. In tomatoes, <i>FW2.2</i> is a PLAC8 motif-containing gene that negatively controls fruit size by regulating cell division and expansion in the carpel ovary during fruit development. However, despite <i>FW2.2</i>, other <i>FWL (FW2.2-Like)</i> genes in tomatoes have not been investigated. In this study, we identified the 21 <i>SlFWL</i> genes, including <i>FW2.2</i>, examined their expression profiles under various abiotic adversity-related conditions. The <i>SlFWL</i> gene structures and motif compositions are conserved, indicating that tomato <i>SlFWL</i> genes may have similar roles. Cis-acting element analysis revealed that the <i>SlFWL</i> genes may participate in light and abiotic stress responses, and they also interacted with a variety of phytohormone-responsive proteins and plant development elements. Phylogenetic analyses were performed on five additional plant species, including <i>Arabidopsis</i>, pepper, soybean, rice and maize, these genes were classified into five subfamilies. Based on the results of collinearity analyses, the <i>SlFWL</i> genes have a tighter homologous evolutionary relationship with soybean, and these orthologous <i>FWL</i> gene pairs might have the common ancestor. Expression profiling of <i>SlFWL</i> genes show that they were all responsive to abiotic stresses, each subgroup of genes exhibited a different expression trend. Our findings provide a strong foundation for investigating the function and abiotic stress responses of the <i>SlFWL</i> family genes. |
