WebThe downregulation of cytokinin biosynthesis genes in the presence of high nitrate was not observed in nlp1 and nlp4 (NIN-Like proteins) mutants, defective in the NLP transcription factors, which mediate nitrate-dependent regulation of gene expression. Moreover, these mutants did not show nitrate-dependent decrease in iP content.
WebApr 30, 2024 · Cytokinin is an important regulator of symbiotic nodule development. Recently, KNOTTED1-LIKE HOMEOBOX 3 transcription factor (TF) was shown to regulate symbiotic nodule development possibly via the activation of cytokinin biosynthesis genes. However, the direct interaction between the KNOX3 TF and its target genes has not … WebThe effects of auxin and cytokinin on the mRNA of every AtIPT in roots were examined by RT-PCR. AtIPT5 and AtIPT7 were upregulated by auxin, suggesting an auxin regulation of cytokinin biosynthesis. All the genes for ATP/ADP isopentenyltransferases that were detectable in roots were downregulated by cytokinin, indicating a feedback regulation.
