Abstract
Trichosanthes kirilowii Maxim. (TK) is a dioecious plant in the Cucurbitaceae for which different sexes have separate medicinal uses. In order to study the genes related to sex determination, transcriptome sequencing was performed on flower buds of male and female plants using the high-throughput sequencing technology. A total of 145,975 unigenes and 7110 DEGs were obtained. There were 6776 DEGs annotated to 1234 GO terms and enriched to 18 functional groups, including five biological processes related to sugar metabolism. KEGG pathway analysis indicated genes involved in hormone transduction, hormone synthesis and carbohydrate metabolism. Many DEGs of TK are involved in reproductive organ formation, hormone signal transduction and regulatory networks. Combining the results of GO, KEGG and qRT-PCR, 11 sex determining candidate genes of TK were selected, including MYB80, MYB108, CER1, CBL9, ABCB19, SERK1, HSP81-3, ACS9, SEP3, AUX1 and YUC6. The results provide a foundation for the study of sex differentiation in TK.

Structural basis for the oligomerization of the MADS domain transcription factor SEPALLATA3 in Arabidopsis. THE PLANT CELL 2014; 26:3603-15. [PMID: 25228343 PMCID: PMC4213154 DOI: 10.1105/tpc.114.127910] [Citation(s) in RCA: 64] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/21/2014] [Revised: 08/20/2014] [Accepted: 08/29/2014] [Indexed: 05/19/2023]
Abstract
In plants, MADS domain transcription factors act as central regulators of diverse developmental pathways. In Arabidopsis thaliana, one of the most central members of this family is SEPALLATA3 (SEP3), which is involved in many aspects of plant reproduction, including floral meristem and floral organ development. SEP3 has been shown to form homo and heterooligomeric complexes with other MADS domain transcription factors through its intervening (I) and keratin-like (K) domains. SEP3 function depends on its ability to form specific protein-protein complexes; however, the atomic level determinants of oligomerization are poorly understood. Here, we report the 2.5-Å crystal structure of a small portion of the intervening and the complete keratin-like domain of SEP3. The domains form two amphipathic alpha helices separated by a rigid kink, which prevents intramolecular association and presents separate dimerization and tetramerization interfaces comprising predominantly hydrophobic patches. Mutations to the tetramerization interface demonstrate the importance of highly conserved hydrophobic residues for tetramer stability. Atomic force microscopy was used to show SEP3-DNA interactions and the role of oligomerization in DNA binding and conformation. Based on these data, the oligomerization patterns of the larger family of MADS domain transcription factors can be predicted and manipulated based on the primary sequence.
