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.

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.

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 ...

Analytical Solution of the Proprio-Graviceptive equation for shoot gravitropism of plants
, 2012 We derive the analytical solutions to the second order generalised gravi-proprioceptive equation given in our recent paper [Bastien et al. 2012]. These equations show how plants adjust to the surrounding gravitation field and highlight the fact that the plant must be able to not only sense its local posture with respect to the gravitational field, but ...

Molecular genetic study on gravitropism and gravitropic growth habit of the Arabidopsis shoot
Molecular genetic study on gravitropism and gravitropic growth habit of the Arabidopsis shootGravitropic response is a control of growth direction with respect to thegravity vector. Gravity sensing process starts with downward movement ofamyloplasts in statocytes and subsequent physiological signaling is presumed toregulate auxin transport. Putative signaling components, Arabidopsis LAZY1(AtLAZY1) and ALTERED RESPONSE TO GRAVITY 1 (ARG1) are ...
