Cytokinin response factors regulate PIN-FORMED auxin transporters [PDF]

, 2015
Auxin and cytokinin are key endogenous regulators of plant development. Although cytokinin-mediated modulation of auxin distribution is a developmentally crucial hormonal interaction, its molecular basis is largely unknown.

The tasiR‐ARF pathway in plants: origin, functions, and interplay of miR‐390, tasiRNAs and ARF3

Plant Biology, Volume 28, Issue 2, Page 328-344, March 2026.
Trans‐acting small interfering RNAs that silence a subset of Auxin Response Factors are crucial for plant growth, developmental timing, proper organ patterning, and coping with stress. Abstract Trans‐acting small interfering RNA (tasiRNAs) are a special type of endogenous small RNAs (sRNAs) found only in plants.

Origin and Development of Phloem and Xylem as Revealed in 3D Models of the Vascular Cylinder in Primary Roots of Oryza sativa L. cv. Hitomebore

Plants
Xylem and phloem are the defining features of vascular plants and are central to their evolutionary success. The origin and development of phloem and xylem within the vascular cylinder of rice primary roots (Oryza sativa L.) were investigated using ...

Spatiotemporal regulation of lateral root organogenesis in Arabidopsis by cytokinin [PDF]

, 2012
The architecture of a plant's root system, established postembryonically, results from both coordinated root growth and lateral root branching. The plant hormones auxin and cytokinin are central endogenous signaling molecules that regulate lateral root ...

The Arabidopsis ATP-BINDING CASSETTE Transporter ABCB21 Regulates Auxin Levels in Cotyledons, the Root Pericycle, and Leaves

Frontiers in Plant Science, 2019
The phytohormone auxin plays significant roles in regulating plant growth and development. In Arabidopsis, a subset of ATP-BINDING CASSETTE subfamily B (ABCB) transporters participate in polar movement of auxin by exclusion from and prevention of ...
