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.

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.

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.

Measuring root system traits of wheat in 2D images to parameterize 3D root architecture models [PDF]

, 2018
Background and aimsThe main difficulty in the use of 3D root architecture models is correct parameterization. We evaluated distributions of the root traits inter-branch distance, branching angle and axial root trajectories from contrasting experimental ...

SGR1, SGR2, and SGR3: Novel Genetic Loci Involved in Shoot Gravitropism in Arabidopsis thaliana [PDF]

Plant Physiology, 1996
In higher plants shoots show a negative gravitropic response but little is known about its mechanism. To elucidate this phenomenon, we have isolated a number of mutants with abnormal shoot gravitropic responses in Arabidopsis thaliana. Here we describe mainly three mutants: sgr1-1, sgr2-1, and sgr3-1 (shoot gravitropism).

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 ...

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 ...

Underground roots monitor aboveground environment by sensing stem-piped light

Communicative & Integrative Biology, 2016
Light is a critical environmental cue for plant growth and development. Plants actively monitor surrounding environments by sensing changes in light wavelength and intensity.

Peptide signaling at the intersection of growth, nutrient sensing, and stress responses

The Plant Journal, Volume 125, Issue 4, February 2026.
SUMMARY Plant endogenous peptides emerge as central regulators of multiple aspects of plant physiology. They are secreted from cells and perceived by plasma membrane localized receptors, which activate downstream signaling pathways to regulate growth and development. In addition, endogenous peptides coordinate physiology with their environment.

Beyond dwarfism: Green Revolution gene Rht-D1b orchestrates tiller angle and canopy architecture in wheat

Crop Journal
The Green Revolution genes Rht-B1b and Rht-D1b encode truncated DELLA proteins that confer gibberellin (GA)-insensitive semi-dwarfism in wheat. Their roles in reducing plant height and enhancing lodging resistance are well established, but their ...
