Promoters of many G2/M phase-specific genes in plants contain mitosis-specific activator (MSA) elements, which act as G2/M phase-specific enhancers and bind with R1R2R3-Myb transcription factors. A least three R1R2R3-Myb proteins are expressed in tobacco (Nicotiana tabacum). To examine the genome-wi...

Temporal and spatial regulation of cell division is central for generating multicellular organs with predictable sizes and shapes. However, it remains largely unclear how genes with mitotic functions are transcriptionally regulated during organogenesis in plants. Here, we showed that a group of R1R2...

R1R2R3-Myb proteins represent an evolutionarily conserved class of Myb family proteins important for cell cycle regulation and differentiation in eukaryotic cells. In plants, this class of Myb proteins are believed to play important roles in cell cycle regulation through transcriptional regulation o...

Tobacco BY-2 cells can be highly synchronized by treatment with an inhibitor of DNA synthesis, aphidicolin. For comprehensive understanding of cell cycle-regulated gene expression in tobacco, microarray analysis was conducted in synchronized cultures of BY-2 cells. Cells were treated with aphidicoli...

Ripening is an important stage of fruit development to determine its quality as a diet. A tomato (Solanum lycopersicum) MADS-box transcription factor, RIPENING INHIBITOR (RIN), has been believed to serve as a regulator of ripening lying upstream of ethylene-dependent and ethylene-independent pathway...

Higher-order chromosome structure is assumed to control various DNA-templated reactions in eukaryotes. Meiotic chromosomes implement developed structures called M-bM-^@M-^\axesM-bM-^@M-^] and M-bM-^@M-^\loopsM-bM-^@M-^]; both are suggested to tether each other, activating Spo11 to catalyze meiotic D...

The tomato MADS-box FRUITFULL (FUL) homologs, FUL1 and FUL2, interact with the main ripening regulator RIPENING INHIBITOR (RIN). To clarify their role in fruit ripening, we generated FUL1/FUL2-suppressed transgenic lines by RNAi. We found that five transgenic lines bearing fruits that did not ripen ...
