2023年11月4日 · Here, we report that miR159, an evolutionarily conserved microRNA, plays an essential role in regulating cell division in rose (Rosa hybrida) petals by modulating cytokinin catabolism. We uncover...

Flight status, tracking, and historical data for CKX159 including scheduled, estimated, and actual departure and arrival times.

2023年10月18日 · Here, we report that miR159, an evolutionarily conserved microRNA, plays an essential role in regulating cell division in rose (Rosa hybrida) petals by modulating cytokinin catabolism. We uncovered that Cytokinin Oxidase/Dehydrogenase6 …

2023年11月4日 · We uncover that Cytokinin Oxidase/Dehydrogenase6 (CKX6) is a target of miR159 in petals. Knocking down miR159 levels results in the accumulation of CKX6 transcripts and earlier cytokinin clearance, leading to a shortened cell division period and smaller petals.

2019年12月23日 · 前期研究结果表明，植物CKX基因家族各成员具有时空表达特异性，不同家族成员可能在不同器官及不同发育阶段对调控细胞分裂素稳态平衡发挥特定的作用（Song et al., 2012, 2015; Jameson & Song, 2016）。

We uncover that Cytokinin Oxidase/ Dehydrogenase6 (CKX6 ) is a target of miR159 in petals. Knocking down miR159 levels results in the accumulation of CKX6 transcripts and earlier cytokinin...

细胞分裂素氧化酶/脱氢酶 (ckx) 不可逆地降解细胞分裂素，调节生长发育，帮助植物应对环境胁迫。虽然ckx基因已在各种植物中得到很好的表征，但它在大豆中的作用仍然难以捉摸。

OsCKX4 is predominantly expressed in leaf blades and roots. It is the dominant CKX, preferentially expressed in the shoot base where crown root primordia are produced, underlining its role in root initiation. OsCKX4 is induced by exogenous auxin and cytokinin in the roots.

本研究根据水稻、拟南芥、玉米等植物中的研究成果，将植物细胞分裂素代谢过程中的关键基因——细胞分裂素氧化/脱氢酶(ckx)作为小麦籽粒产量的功能候选基因，通过遗传作图、基因多样性研究、表达分析等途径分析了ckx基因与小麦产量及其构成因素间可能 ...
