Functionally different PIN proteins control auxin flux during bulbil development in Agave tequilana [PDF]

, 2015
In Agave tequilana, reproductive failure or inadequate flower development stimulates the formation of vegetative bulbils at the bracteoles, ensuring survival in a hostile environment.

SMXL3 controls multiple aspects of Arabidopsis development via EAR motif‐dependent and ‐independent functions

The Plant Journal, Volume 125, Issue 5, March 2026.
SUMMARY SMAX1‐LIKE (SMXL) proteins, previously linked to strigolactone and karrikin signalling, play diverse and partially redundant roles in plant development. The divergent SMXL4 superclade—comprising SMXL3, SMXL4 and SMXL5—is not subject to strigolactone‐ or karrikin‐dependent proteolysis.

ZIFL1.1 transporter modulates polar auxin transport by stabilizing membrane abundance of multiple PINs inArabidopsisroot tip [PDF]

, 2013
Cell-to-cell directional flow of the phytohormone auxin is primarily established by polar localization of the PIN auxin transporters, a process tightly regulated at multiple levels by auxin itself.

Evidence for a Relationship between H⁺ Excretion and Auxin in Shoot Gravitropism [PDF]

Plant Physiology, 1983
The role of auxin and protons in the gravitropic response of the sunflower (Helianthus annuus L. cv Sungold) hypocotyl has been investigated. No physiological asymmetry in acid-growth capacity could be detected between the upper and lower surfaces of gravistimulated hypocotyls.

OsAux1 is required for nutritropism in rice roots

The Plant Journal, Volume 125, Issue 5, March 2026.
SUMMARY Nutritropism is a directional root growth response to nutrient gradients, and rice (Oryza sativa L.) roots show nutritropism toward sources containing ammonium. Here, we report characterization of an EMS‐mutagenized rice plant that shows a complete defect in nutritropism.

Auxin fluxes in the root apex co-regulate gravitropism and lateral root initiation [PDF]

, 2008
International audienceRoot architecture plays an important role in water and nutrient acquisition and in the ability of the plant to adapt to the soil. Lateral root development is the main determinant of the shape of the root system and is controlled by ...

High temperature attenuates the gravitropism of inflorescence stems by inducing SHOOT GRAVITROPISM 5 alternative splicing in Arabidopsis [PDF]

New Phytologist, 2015
Summary In higher plants, gravitropism proceeds through three sequential steps in the responding organs: perception of gravity signals, signal transduction and asymmetric cell elongation. Light and temperature also influence the gravitropic orientation of plant organs. A series of Arabidopsis shoot gravitropism (sgr) mutants has been shown to exhibit

Soybean Auxin Transporter PIN3 Regulates Nitrate Acquisition to Improve Nitrogen Use and Seed Traits

Advanced Science, Volume 13, Issue 12, 27 February 2026.
Xu et al. discovers that switching off auxin transporters in soybean, PIN3a and PIN3b, disrupts auxin flow; this triggers ARF‐STF3/4 signal cascade to activate the nitrate importer NPF2.13 and soil nitrogen acquisition. Multi‐year field trials show edited soybeans maintain yield with higher oil content, offering a potential genetic route to improve ...

Developmental biology of wood formation [PDF]

, 2003
The wood-forming vascular cambium is responsible for the production of a large part of the biomass on this planet. Yet, there is only limited knowledge on how cell proliferation and differentiation in the cambial meristem are regulated.

Functional characterization of NRT1/PTR FAMILY transporters: looking for a needle in a haystack

New Phytologist, Volume 249, Issue 3, Page 1124-1144, February 2026.
Summary NRT1/PTR FAMILY (NPF) transporters play crucial roles in plant physiology and development due to their involvement in nitrogen nutrition and their ability to transport multiple signaling molecules and metabolites. Whereas most eukaryotic and prokaryotic NPF orthologs are peptide transporters, most flowering plant NPF transport other substrates ...
