The Relationship between AGAMOUS and Cytokinin Signaling in the Establishment of Carpeloid Features

Plants, 2021
Gynoecium development is dependent on gene regulation and hormonal pathway interactions. The phytohormones auxin and cytokinin are involved in many developmental programs, where cytokinin is normally important for cell division and meristem activity ...

Cytokinins

YAKUGAKU ZASSHI, 1994
Cytokinins which promote cell division and cell differentiation of plants are structurally classified into two groups: purine-type cytokinins and phenylurea-type cytokinins. Structural modification of the two types led a potent cytokinin, N-(2-chloro-4-pyridyl)-N'-phenylurea (forchlorfenuron). Structure-activity relationship was discussed.

Fluorescent reporter lines for auxin and cytokinin signalling in barley (Hordeum vulgare). [PDF]

PLoS ONE, 2018
The phytohormones auxin and cytokinin control development and maintenance of plant meristems and stem cell systems. Fluorescent protein reporter lines that monitor phytohormone controlled gene expression programmes have been widely used to study ...

Identification and characterization of the first cytokinin glycosyltransferase from rice

Rice, 2019
Background Cytokinins are one of the five major hormones families in plants and are important for their normal growth and environmental adaptability. In plants, cytokinins are mostly present as glycosides in plants, and their glycosylation modifications ...

ACAULIS5 Is Required for Cytokinin Accumulation and Function During Secondary Growth of Populus Trees

Frontiers in Plant Science, 2020
In the primary root and young hypocotyl of Arabidopsis, ACAULIS5 promotes translation of SUPPRESSOR OF ACAULIS51 (SAC51) and thereby inhibits cytokinin biosynthesis and vascular cell division.

Histone Modification Complex JMJ704‐HDA709 Negatively Regulates Salinity Tolerance in Rice

Advanced Science, EarlyView.
This study reveals that the rice histone demethylase JMJ704 interacts with HDA709―a H3K9ac deacetylase characterized herein―to form a chromatin‐modifying complex. Under salt stress, OsWRKY72 recruits this complex through interaction with JMJ704 to target loci, repressing the expression of oxidative stress and salt‐responsive genes via removal of ...

Characterization of a cytokinin-binding protein locus in Mycobacterium tuberculosis

Journal of Bacteriology
Cytokinins are adenine-based hormones that have been well-characterized in plants but are also made by bacteria, including the human-exclusive pathogen Mycobacterium tuberculosis. Like plants, M.

A B-ARR-mediated cytokinin transcriptional network directs hormone cross-regulation and shoot development

Nature Communications, 2018
Cytokinin fulfills its diverse roles in planta through a series of transcriptional responses. We identify the in vivo DNA binding site profiles for three genetically redundant type-B ARABIDOPSIS RESPONSE REGULATORS (B-ARRs): ARR1, ARR10, and ARR12.

Epidermal METTL1‐Mediated m7G Modification Drives Psoriatic Inflammation by Stabilizing Bdkrb1 and Orchestrating Neutrophil Recruitment

Advanced Science, EarlyView.
This study unveils an unrecognized pro‐inflammatory epitranscriptomic checkpoint in psoriasis. By installing m7G modifications on the 5′ UTR of Bdkrb1 mRNA, METTL1 enhances receptor stability to orchestrate keratinocyte‐driven neutrophil recruitment via p38 MAPK signaling.

Nodulating Legumes Are Distinguished by a Sensitivity to Cytokinin in the Root Cortex Leading to Pseudonodule Development

Frontiers in Plant Science, 2019
Root nodule symbiosis (RNS) is a feature confined to a single clade of plants, the Fabids. Among Fabids capable of RNS, legumes form root cortex-based nodules in symbioses with rhizobia, while actinorhizal species form lateral root-based nodules with ...
