The Peach RGF/GLV Signaling Peptide pCTG134 Is Involved in a Regulatory Circuit That Sustains Auxin and Ethylene Actions [PDF]

, 2017
In vascular plants the cell-to-cell interactions coordinating morphogenetic and physiological processes are mediated, among others, by the action of hormones, among which also short mobile peptides were recognized to have roles as signals.

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 ...

Interplay of the two ancient metabolites auxin and MEcPP regulates adaptive growth. [PDF]

, 2018
The ancient morphoregulatory hormone auxin dynamically realigns dedicated cellular processes that shape plant growth under prevailing environmental conditions. However, the nature of the stress-responsive signal altering auxin homeostasis remains elusive.

Auxin Homeostasis in Arabidopsis Ovules Is Anther-Dependent at Maturation and Changes Dynamically upon Fertilization

Frontiers in Plant Science, 2017
The plant hormone auxin is a vital component for plant reproduction as it regulates the development of both male and female reproductive organs, including ovules and gynoecia.

The PIN-FORMED (PIN) protein family of auxin transporters [PDF]

, 2009
The PIN-FORMED (PIN) proteins are secondary transporters acting in the efflux of the plant signal molecule auxin from cells. They are asymmetrically localized within cells and their polarity determines the directionality of intercellular auxin flow.

Evolution and structural diversification of PILS putative auxin carriers in plants

Frontiers in Plant Science, 2012
The phytohormone auxin contributes to virtually every aspect of the plant development. The spatiotemporal distribution of auxin depends on a complex interplay between auxin metabolism and intercellular auxin transport.

Auxin-dependent cell cycle reactivation through transcriptional regulation of Arabidopsis E2Fa by lateral organ boundary proteins [PDF]

, 2011
Multicellular organisms depend on cell production, cell fate specification, and correct patterning to shape their adult body. In plants, auxin plays a prominent role in the timely coordination of these different cellular processes. A well-studied example

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.

Transcription of TIR1-controlled Genes Can be Regulated within 10 Minutes by an Auxin-induced Process. Can TIR1 be the Receptor?

Frontiers in Plant Science, 2016
ABP1 and TIR1/AFBs are known as auxin receptors. ABP1 is linked to auxin responses several of which are faster than ten minutes. TIR1 regulates auxin-induced transcription of early auxin genes also within minutes.

Auxin Signaling [PDF]

Plant Physiology, 2017
Auxin acts as a general co-ordinator of plant growth and development, transferring information over both long and short ranges. Auxin famously appears to be extraordinarily multi-functional, with different cells responding very differently to changes in auxin levels.
