Encodes1
The rice (Oryza sativa L.) Gn1a/OsCKX2 (Grain number 1a/Cytokinin oxidase 2) gene, which encodes a cytokinin oxidase, has been identified as a major quantitative trait locus contributing to grain number improvement in rice breeding practice. (scite.ai)
Degradation2
The operon codifies for genes involved in cytokinin synthesis and degradation (orf 4,5,6), in particular for an isopentenyl transferase, a cytokinin oxidase and a glutation-s transferase. (wikipedia.org)
It was supposed that the first three genes supply energy for the synthesis and degradation of cytokinin, performed by the last three genes of the operon: R. fascians can actually produce and degrade zeatin and isopentenil adenine. (wikipedia.org)
Zeatin3
Later, zeatin was identified as the first naturally occurring cytokinin in immature maize endosperm ( Letham, 1973 ), and turns out to be the abundant cytokinin in coconut milk. (bioone.org)
The most common class of cytokinins have isoprenoid side chains, including the most abundant cytokinin in Arabidopsis, trans-zeatin. (bioone.org)
The assay was also adapted for other substrates than N6-(2-isopentenyl)adenine, such as zeatin and the aromatic cytokinins, although an enzyme which degrades the latter compounds has not yet been identified. (nih.gov)
Adenine2
Naturally occurring cytokinins are adenine derivatives with distinct substitutions attached to the N6position of the adenine ring ( Figure 1 ). (bioone.org)
The compound cytokin oxidase (orf4) can also create adenine with a reactive nitrogen in position 6, which can react with other lateral chains, to form cytokininn-like compounds, more efficient in inducing plant tissue growth. (wikipedia.org)
Genes2
Plants tightly regulate the availability of GA by coordinating the activation and deactivation of multiple biosynthesis genes of GA in different tissues at various developmental stages [ 1 ]. (biomedcentral.com)
We also identified recurrent HBV integration events (in ≥ 4 HCCs) that were validated by RNA sequencing (RNA-seq) and Sanger sequencing at the known and putative cancer-related TERT, MLL4 and CCNE1 genes, which showed upregulated gene expression in tumor versus normal tissue. (scite.ai)
Gibberellin2
GmGA20OX ( Glyma.07g08950 ) and GmNFYA ( Glyma.02g47380 ), which encode gibberellin 20 oxidase and nuclear factor Y subunit A, were screened by transcriptome analysis from 40 samples of developing soybean seeds in cultivated and wild soybean. (biomedcentral.com)
At the same time, Bacillus amyloliquefaciens can produce gibberellin, indole acetic acid, cytokinin, abscisic acid, and other physiologically active substances and amino acids to reduce plant diseases and improve disease resistance, Promote crop growth, increase crop yield and improve quality.

Then came the rise of technological improvements to imaging and gene editing, such as computed tomography (CT) scanners which can create 3D reconstructions of internal plant structures without destroying tissue, and drones with laser scanners, depth sensors, and thermal imaging cameras to help improve crop breeding.

We provide evidence showing that Nal1 is richly expressed in vascular tissues and that mutation of this gene leads to significantly reduced polar auxin transport capacity. (scite.ai)
Leaf4
Since their discovery, cytokinins have been implicated to play a role in almost all aspects of plant growth and development, including cell division, shoot initiation and growth, leaf senescence, and photomorphogenic development ( Mok and Mok, 1994 ). (bioone.org)
Source is defined as tissues producing photosynthesis such as the upper three leaves, especially the flag leaf, sheath, and so on. (frontiersin.org)
Presence of R. fascians was also observed in intercellular spaces inside tissues (in leaf or galls) and even inside cell walls. (wikipedia.org)
To understand GA-DELLA signaling in perennial species, we created ten GA-insensitive transgenic grapevines carrying a DELLA mutant allele ( Vvgai1 ) in the background of Vitis vinifera 'Thompson Seedless' and conducted comprehensive analysis of their RNA expression profiles in the shoot, leaf and root tissues.
