2014年2月17日 · Degradation of the plant hormone cytokinin is catalyzed by cytokinin oxidase/dehydrogenase (CKX) enzymes. The Arabidopsis thaliana genome encodes seven CKX proteins which differ in subcellular localization and substrate specificity.

细胞分裂素类激素对于植物的生长发育是不可或缺的。细胞分裂素氧化酶/脱氢酶 (ckx) 有助于调节内源性细胞分裂素水平的动态平衡。然而，人们对烟草的ckx基因( ntckxs )知之甚少。计算机分析用于分离、表征和阐明 15 个ntckx基因的系统发育关系。

2024年4月1日 · The role of CKX genes encoding cytokinin oxidase/dehydrogenase in determining plant resistance to abiotic stress factors and their yield was analyzed. The molecular genetic ways of regulating the activity of CKX genes are characterized.

2004年8月27日 · Increased enzyme activity causes drastic abnormalities in the growth and development of the CKX overexpressing plants, highlighting the fundamental role of CKX in the control of cytokinin levels. Sequence and biochemical analysis has shown that CKX is a flavoenzyme that belongs to a class of oxidoreductases that encompasses oxidases and ...

2024年10月1日 · This comprehensive study provides information on the identification and characterization of CKX genes in pigeonpea. A genome-wide analysis identified 18 CKX genes, each with distinct structure, expression patterns, and possible diverse functions. Domain analysis revealed the presence of the sequences including FAD and CK-Binding domain, and ...

2014年7月22日 · Cytokinin oxidases (CKXs) are the mostwidely recognized enzymes regulating cellular cytokinin level in plants. It has been well documented that cellular CKX levels are associated with morphogenetic responses in plants.

Degradation of the plant hormone cytokinin is catalyzed by cytokinin oxidase/dehydrogenase (CKX) enzymes. The Arabidopsis thaliana genome encodes seven CKX proteins which differ in subcellular localization and substrate specificity.

细胞分裂素氧化酶/脱氢酶（CKXs）参与各种生理过程，包括细胞分裂素（CKs）分解代谢，根系结构和对植物中非生物胁迫的响应。 苜蓿（紫花苜蓿）是一种广泛种植的草料，经常受到高盐度的威胁，而CKXs缓解苜蓿盐分胁迫的潜在作用却缺乏关注。 在这项研究中，我们从苜蓿MsCKX（MK177192）中分离出CKX基因，并通过在拟南芥中过表达来鉴定其生物学功能。 MsCKX与其他豆科植物的CKX具有很高的序列同一性，尤其是Medi藜苜蓿（Medicago …

In this study, we comprehensively examined the expression patterns and functions of the CKX s in rice by using CRISPR/Cas9 technology to construct mutants of all 11 genes. The results revealed that the ckx single-mutants and higher-order ckx4 ckx9 mutant lines showed functional overlaps and sub-functionalization.

Cytokinins have opposing actions in shoot and root growth-actions shown to involve cytokinin dehydrogenase (CKX), the enzyme that inactivates cytokinin. We revise and provide unambiguous names for the CKX gene family members in wheat, based on the most recently released wheat genome database, IWGSC RefSeq v1.0 & v2.0.
