Since they come from the same progenitor gene, they often have related biochemical functions. A collection of genes, usually but not necessarily situated together, that have either a common or associated function or have similar nucleotide sequences. 33, 18701874. Figure6 Analysis of the expression patterns of the selected CaCYP genes in different abiotic stresses. Partial Localization of Three Gene Clusters. doi:10.1016/j.molp.2020.06.009, Dos Reis, M. V., Rouhana, L. V., Sadeque, A., Koga, L., Clough, S. J., Calla, B., et al. A gene family is a set of several similar genes, formed by duplication of a single original gene, that generally have similar biochemical functions. MNB1a is a DNA-binding protein of maize that contains a unique DNA-binding domain, designated the Dof domain, and its gene belongs to a multigene family. A multigene family is a member of a family of related proteins encoded by a set of similar genes. Genetics. The positions of exons within the coding sequence can be used to infer common ancestry. doi:10.1007/s12042-008-9022-1, Nelson, D., Werck-Reichhart, D. (2011). The .gov means its official. The first P450 X-ray crystal structure was obtained from bacterial P450cam (Poulos etal., 1985). From: Molecular Medical Microbiology (Second Edition), 2015 Related terms: View all Topics Front Immunol. 43, 23252335. 2021 Sep 27;38(10):4077-4094. doi: 10.1093/molbev/msab182. Figure3 Collinearity analysis of the P450 family in pepper. The A-type subfamily contained the CYP71 clan, which included most of the P450 genes. Members of the CYP74 clan were involved in the metabolism of oxygen and lipids, including JA, which played a role in cellular signaling and defense (Wasternack and Feussner, 2018). Disclaimer. MEME SUITE: tools for motif discovery and searching. 146, 238248. The close linkage of the genes in a family appears to be a consequence of the fact that their ocntrol and evolutionary mechanisms may only operate on tandemly linked genes. Natl. When the gene is needed in large amounts. Each of the genes has two introns located at conserved sites within the mature peptide-coding regions.

To further explore the function and expression pattern of CaCYP genes, we analyzed the RNA-seq data of pepper leaves treated with four hormones, including methyl jasmonate (MeJA), salicylic acid (SA), ethylene (ET), and abscisic acid (ABA) (Lee etal., 2020) (Figure8; Supplementary Figure6). 24, 109120.

This burst of gene duplication likely contributed to adaptation to specific ecological niches and speciation. In Arabidopsis, the A type includes the CYP71 subfamily, and the non-A type has eight different subfamilies, namely, CYP51, CYP72, CYP710, CYP711, CYP74, CYP85, CYP86, and CYP97 (Bak etal., 2011). Federal government websites often end in .gov or .mil. Food Saf. Unauthorized use of these marks is strictly prohibited. Structure, map position, and evolution of two newly diverged mouse Ig VH gene families. CaCYP250 and CaCYP251 were also a pair of tandem duplicated genes. This site needs JavaScript to work properly. CYP86s catalyzed the oxidation of fatty acids to a variety of oxidation derivatives, and they produced a wide range of precursors to form waterproof biopolymers, such as cutin and suberin, which are essential for water transport or prevention of water loss. Figure2 Phylogenetic tree of P450 genes from Arabidopsis, pepper, tomato, and potato. The expression map showed that pepper CaCYP genes had strong tissue specificity in the roots and flowers, especially in the CYP71, CYP72, CYP85, and CYP86 clans. 1866, 141154. 8. doi:10.3389/fpls.2017.01519, Tian, X., Ruan, J. X., Huang, J. Q., Yang, C. Q., Fang, X., Chen, Z. W., et al. Some of the most interesting genetic systems under the investigation today are known or potential informational multigene families. doi:10.1042/bst0341206, Guttikonda, S. K., Trupti, J., Bisht, N. C., Chen, H., An, Y. Q., Pandey, S., et al. Collinearity analysis showed that CaCYP77 had four pairs of homologous genes and CaCYP325 had three pairs of homologous genes between pepper and tomato. In this study, we identified 478 P450 genes in pepper from the pepper genome. In the CYP74 clan, six CaCYP genes (66.7% of the total CYP74 clan) were related to the pericarp development before the fruit mature stage. In the CYP85 clan, eight genes were related to cold treatment, 13 genes were related to heat treatment, and seven genes had high expression levels in D-mannitol treatment and NaCl treatment. The similarity can be either for the entire sequence or partial limited to specific domains. your institution. The number of tandem duplicated genes was different on each chromosome and 17, 5, 20, 15, 5, 7, 14, 3, 3, 10, 2, and 5 pairs of tandem duplicated genes were distributed on chromosomes from 1 to 12 (Supplementary Table3). Careers. CM334) seedlings in a growth room at 24C 1C with a 16-h light and an 8-h dark photoperiod. At the same time, it has been reported that CYP86s have had a positive regulatory effect on the plant immune system and a strong defense against pathogens (Wang etal., 2020a). A haploid model. lation dynamics of gene lineages within a multigene family is If so, just upload it to PowerShow.com. CaCYP95, CaCYP30, CaCYP275, CaCYP83, CaCYP51, CaCYP81, and CaCYP332 were related to pericarp development. In this study, we used the bioinformatics methods to analyze the number, chromosomal localization, replication events, phylogeny, and gene expression as well as provided a panoramic view of the P450 gene family in pepper. Complex Multigene Family . Embo. (2017). Molec. doi:10.1105/tpc.021345, Bozak, K. R., Yu, H., Sirevg, R., Christoffersen, R. E. (1990). Arabidopsis Book 9, e0144. OSCA1 channel is a hyperosmolarity-induced Ca2 + channel identified by using Ca 2 + imaging forward genetics approach in Arabidopsis. 1, Reviews3003. Anal Biochem 132:613, Fluhr R, Moses P, Morelli G, Coruzzi G, Chua N-H (1986) Expression dynamics of the pea rbcS multigene family and organ distribution of the transcripts. In addition to evolving new functions, the latter mode of evolution generates a new multigene family whose members are preadapted to interact with those of the old family. This phenomenon has also been observed in pepper, where the expression patterns of the duplicated CaCYP gene pairs were different and had different functions. doi:10.1007/s11101-006-9015-3, Nelson, D. R. (2009). In addition, a total of 16 genes in the CYP72 clan were associated with cold treatment, and most of the remaining genes were expressed under the other three abiotic stresses. doi:10.1073/pnas.1306373110, Krishnamurthy, P., Vishal, B., Ho, W. J., Lok, F. C. J., Lee, F. S. M., Kumar, P. P. (2020). The phylogenetic tree included multiple plant species and was constructed using MEGA 11 with the NJ method, and the selected model was the Poisson model with 1,000 bootstrap replications (Kumar etal., 2016). The results showed that in the CYP71 clan, some genes, such as CaCYP57, CaCYP63, CaCYP186, CaCYP113, and CaCYP461, showed high expression at placenta development before the fruit mature stage [at stage 1, stage 2, stage 3, and mature green (MG)], and some genes, such as CaCYP40, CaCYP78, CaCYP175, CaCYP240, CaCYP315, and CaCYP352, showed high expression at pericarp development before the fruit mature stage (at stage 1, stage 2, stage 3, and MG) (Figure5; Supplementary Figure4).
