Cytokinin hormones are important regulators of development and environmental responses
of plants that execute their action via the molecular machinery of signal perception and …

Cytokinins (CKs) are evolutionally old and highly conserved low-mass molecules that have
been identified in almost all known organisms. In plants, they evolved into an important …

Plant growth promoting rhizobacteria (PGPR) are diverse, naturally occurring bacteria that
establish a close association with plant roots and promote the growth and immunity of …

The flag leaf and grain belong to the source and sink, respectively, of cereals, and both have
a bearing on final yield. Premature leaf senescence significantly reduces the photosynthetic …

Crown roots constitute the majority of the rice (Oryza sativa) root system and play an
important role in rice growth and development. However, the molecular mechanism of crown …

Degradation of the plant hormone cytokinin is catalyzed by cytokinin oxidase/
dehydrogenase (CKX) enzymes. The A rabidopsis thaliana genome encodes seven CKX …

Key message Most known phytohormones regulate moss development. We present a
comprehensive view of the synthesis and signaling pathways for the most investigated of …

Cytokinin oxidase/dehydrogenase (CKX) irreversibly degrades cytokinin, regulates growth
and development, and helps plants to respond to environmental stress. Although the CKX …

Poaceae members shared a whole-genome duplication called rho. However, little is known
about the evolutionary pattern of the rho-derived duplicates among Poaceae lineages and …

Key message PpCKX1 localizes to vacuoles and is dominantly expressed in the stem cells.
PpCKX1 regulates developmental changes with increased growth of the rhizoid and …
