“…Plant growth is driven by the process of cell division, coupled with subsequent cellular elongation and differentiation (Beemster et al, 2003;Jakoby and Schnittger, 2004). Cell division plays a role both in the developmental processes that create plant architecture and in the modulation of plant growth rates in response to the environment (Cockcroft et al, 2000;Beemster et al, 2002;De Veylder et al, 2011;Polyn et al, 2015).…”

These physiological phenomena were confirmed at the molecular level. Two genes (CS-ACS1G and CS-ACS2) which encode a key enzyme in the ethylene biosynthesis pathway, 1-aminocyclopropane-1-carboxylic acid (ACC) synthase, were identified as being related to sex expression in cucumber plants. The CS-ACS1G gene, which exists in gynoecious cucumber plants but not in monoecious cucumber plants, was closely linked to the F gene (Trebitsh et al., 1997 Monoecious cucumber (Cucumis sativus L.) produces male and female flowers on the same plant, but application of ethylene promotes expression of female flowers. In the early bisexual stage, all flower buds contain primordia for both stamens and pistils and sexual differences are established by the selective arrest of sexual organ primordia. The expression of six cell cycle-related genes [Cs Cyclin A (CsCycA), CsCycB, CsCycD3; 1, CsCycD3; 2, Cs Cyclin-dependent kinase A CsCDKA), and CsCDKB] was analyzed in male and female flower buds to investigate cell cycle activity in sexual organs. CsCycA was expressed specifically in the area containing arrested stamen primordia (ACASP) in female flower buds, but was barely detected in male flower buds. Expression of the other five genes was detected in the ACASP but not in pistils of female flower buds. Expression of all six genes was elevated transiently following the application of 2-chloroethylphosphonic acid (ethephon), an ethylene-releasing agent, to the shoot apices. The correlation of expression of these genes with the formation of female flowers suggests they play a role in the arrest of stamens of female flowers in monoecious cucumber plants.

“…G1 and G2 are two phases during which the cell determines whether it will go into the following S phase or M phase. The mechanism for cell cycle control is highly conserved among different organisms, and the major regulators of the plant cell cycle have been identified, including cyclin-dependent kinases (CDKs), cyclins, CDK-inhibitory proteins, the WEE kinase and components of the RB/ E2F/DP pathway [16][17][18]. In Arabidopsis, two classes of CDKs and 49 cyclins have been identified.…”

“…CDKs and cyclins can form kinase complexes, which phosphorylate various substrates, leading to the progression of the cell cycle. All the components of the cell cycle progression may be regulated at various levels and by different developmental or environmental factors [17,18]. Plant hormones, including auxin, cytokinin, brassinosteroids, gibberellin and abscisic acid, also affect the cell cycle and cell division [18].…”

“…Thus, there exist many cell-cycle variants with considerable deviations from the prototypical organization of the cell cycle with its four phases, G1-, S-, G2-, and M-phase, in the context of a multicellular organism (1,2). Very common in both animal and plant species are endoreplication cycles, also called endoreduplication, in which M-phase is skipped but cells repeatedly progress through S-phase (3)(4)(5)(6).…”

One of the predominant cell-cycle programs found in mature tissues is endoreplication, also known as endoreduplication, that leads to cellular polyploidy. A key question for the understanding of endoreplication cycles is how oscillating levels of cyclindependent kinase activity are generated that control repeated rounds of DNA replication. The APC/C performs a pivotal function in the mitotic cell cycle by promoting anaphase and paving the road for a new round of DNA replication. However, using marker lines and plants in which APC/C components are knocked down, we show here that outgrowing and endoreplicating Arabidopsis leaf hairs display no or very little APC/C activity. Instead we find that RBX1-containing Cullin-RING E3 ubiquitin-Ligases (CRLs) are of central importance for the progression through endoreplication cycles; in particular, we have identified CULLIN4 as a major regulator of endoreplication in Arabidopsis trichomes. We have incorporated our findings into a bio-mathematical simulation presenting a robust two-step model of endoreplication control with one type of cyclindependent kinase inhibitor function for entry and a CRL-dependent oscillation of cyclin-dependent kinase activity via degradation of a second type of CDK inhibitor during endoreplication cycles.cell cycle | endoreduplication | CDK inhibitor | cell differentiation | protein degradation
