Abstract

The expression of a KNOX class 1 gene OSH1 is induced by cytokinin during regeneration of shoots from callus in Oryza sativa L. (rice). This cytokinin-induced expression was enhanced by overexpression of homologues of cytokinin-signalling phosphorelay genes such as a histidine kinase gene OHK3, a phosphotransmitter gene OHP2 and a response regulator gene ORR1 in cultured cells. Regionally overlapped expression of these genes and OSH1 was observed in shoot apex. These results suggest that these cytokinin-signalling genes are positive regulators of the expression of OSH1, and mediate the OSH expression upon shoot regeneration from callus in rice.

细胞分裂素诱导的水稻芽再生愈伤组织中OSH1的表达。

细胞分裂素在水稻愈伤组织再生过程中诱导KNOX 1类基因OSH1的表达。这种细胞分裂素诱导的表达通过细胞分裂素信号磷酸化基因的同源物如组氨酸激酶基因OHK3、磷酸化递质基因OHP2和反应调节基因ORR1在培养细胞中过表达而增强。这些基因与OSH1在茎尖的表达存在区域重叠。这些结果表明，这些细胞分裂素信号基因是OSH1表达的正调控因子，并介导水稻愈伤组织再生过程中OSH1的表达。

期刊介绍： Plant Biotechnology is an international, open-access, and online journal, published every three months by the Japanese Society for Plant Biotechnology. The journal, first published in 1984 as the predecessor journal, “Plant Tissue Culture Letters” and became its present form in 1997 when the society name was renamed to Japanese Society for Plant Cell and Molecular Biology, publishes findings in the areas from basic- to application research of plant biotechnology. The aim of Plant Biotechnology is to publish original and high-impact papers, in the most rapid turnaround time for reviewing, on the plant biotechnology including tissue culture, production of specialized metabolites, transgenic technology, and genome editing technology, and also on the related research fields including molecular biology, cell biology, genetics, plant breeding, plant physiology and biochemistry, metabolic engineering, synthetic biology, and bioinformatics.
