“…We identified 658 CYCB genes in 24 angiosperms. Consistent with previous studies [6,23,24], the plant CYCB genes could be separated into three groups, with all species having the fewest members in Group 3. We observed that the expansion and shrinkage of CYCB members occurred in terms of copy-number within B. napus accessions and among angiosperm species, corresponding with previous studies [24][25][26].…”

Cyclin B (CYCB) is a regulatory subunit of cyclin-dependent kinase (CDK), the concentration of which fluctuates to regulate cell cycle progression. Extensive studies have been performed on cyclins in numerous species, yet the evolutionary relationships and biological functions of the CYCB family genes in Brassica napus remain unclear. In this study, we identified 299 CYCB genes in 11 B. napus accessions. Phylogenetic analysis suggests that CYCB genes could be divided into three subfamilies in angiosperms and that the CYCB3 subfamily members may be a newer group that evolved in eudicots. The expansion of BnaCYCB genes underwent segmental duplication and purifying selection in genomes, and a number of drought-responsive and light-responsive cis-elements were found in their promoter regions. Additionally, expression analysis revealed that BnaCYCBs were strongly expressed in the developing seed and silique pericarp, as confirmed by the obviously reduced seed size of the mutant cycb3;1 in Arabidopsis thaliana compared with Col-0. This study provides a comprehensive evolutionary analysis of CYCB genes as well as insight into the biological function of CYCB genes in B. napus.

“…Since the first plant cyclin gene was cloned in soybean [ 16 ], more cyclins have been found in various plants [ 11 , 12 ]. A previous study indicates that plant cyclins can be classified into 10 groups, but there are only eight ancestral genes in the most recent common ancestor (MRCA) of extant green plants [ 17 ]. Forty-nine cyclins have been identified in the Arabidopsis thaliana genome, which were assigned to A-, B-, C-, D-, H-, L-, T-, U-, SDS-, and J18-type.…”

Cyclins, together with highly conserved cyclin-dependent kinases (CDKs), play an important role in the process of cell cycle in plants, but less is known about the functions of cyclins in legume plants, especially Medicago truncatula. Our genome-wide analysis identified 58, 103, and 51 cyclin members in the M. truncatula, Glycine max, and Phaseolus vulgaris genomes. Phylogenetic analysis suggested that these cyclins could be classified into 10 types, and the CycB-like types (CycBL1-BL8) were the specific subgroups in M. truncatula, which was one reason for the expansion of the B-type in M. truncatula. All putative cyclin genes were mapped onto their own chromosomes of each genome, and 9 segmental duplication gene pairs involving 20 genes were identified in M. truncatula cyclins. Determined by quantitative real-time PCR, the expression profiling suggested that 57 cyclins in M. truncatula were differentially expressed in 9 different tissues, while a few genes were expressed in some specific tissues. Using the publicly available RNAseq data, the expression of Mtcyclins in the wild-type strain A17 and three nodule mutants during rhizobial infection showed that 23 cyclins were highly upregulated in the nodulation (Nod) factor-hypersensitive mutant sickle (skl) mutant after 12 h of rhizobium inoculation. Among these cyclins, six cyclin genes were also specifically expressed in roots and nodules, which might play specific roles in the various phases of Nod factor-mediated cell cycle activation and nodule development. Our results provide information about the cyclin gene family in legume plants, serving as a guide for further functional research on plant cyclins.

“…Angiosperms have undergone an extensive expansion of the cyclin family in comparison to yeast and mammals, containing for instance a total of 10 different cyclin families with more than 50 protein‐encoding cyclin genes in Arabidopsis (Wang et al , 2004 ; Jia et al , 2014 ). For most of these genes, functional information is still lacking.…”

B1‐type cyclins control microtubule organization during cell division in Arabidopsis

Flowering plants contain a large number of cyclin families, each containing multiple members, most of which have not been characterized to date. Here, we analyzed the role of the B1 subclass of mitotic cyclins in cell cycle control during Arabidopsis development. While we reveal CYCB1;5 to be a pseudogene, the remaining four members were found to be expressed in dividing cells. Mutant analyses showed a complex pattern of overlapping, developmentspecific requirements of B1-type cyclins with CYCB1;2 playing a central role. The double mutant cycb1;1 cycb1;2 is severely compromised in growth, yet viable beyond the seedling stage, hence representing a unique opportunity to study the function of B1-type cyclin activity at the organismic level. Immunolocalization of microtubules in cycb1;1 cycb1;2 and treating mutants with the microtubule drug oryzalin revealed a key role of B1-type cyclins in orchestrating mitotic microtubule networks. Subsequently, we identified the GAMMA-TUBULIN COMPLEX PROTEIN 3-INTERACTING PROTEIN 1 (GIP1/MOZART) as an in vitro substrate of B1-type cyclin complexes and further genetic analyses support a potential role in the regulation of GIP1 by CYCB1s.
