Auxins and environmental factors regulate root gravitropism

Biologia Plantarum
Roots are important for plant anchoring, water and nutrient absorption, and other physiological processes. Gravity is a primary determinant of the spatial distribution of plant roots in the soil.

Inclination not force is sensed by plants during shoot gravitropism [PDF]

, 2016
International audienceGravity perception plays a key role in how plants develop and adapt to environmental changes. However, more than a century after the pioneering work of Darwin, little is known on the sensing mechanism.

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 ...

The RGI1–BAK1 module acts as the main receptor–coreceptor pair for regulating primary root gravitropism and meristem activity in response to RGF1 peptide in Arabidopsis

Plant Signaling & Behavior, 2023
ROOT MERISTEM GROWTH FACTOR1 (RGF1) and its receptors RGF1 INSENSITIVEs (RGIs), a group of leucine-rich repeat receptor kinases, promote primary root meristem activity via a mitogen-activated protein kinase (MPK) signaling cascade and control root ...

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 ...

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.

Suppression of asymmetric acid efflux and gravitropism in maize roots treated with auxin transport inhibitors of sodium orthovanadate [PDF]

In gravitropically stimulated roots of maize (Zea mays L., hybrid WF9 x 38MS), there is more acid efflux on the rapidly growing upper side than on the slowly growing lower side.

Gradients of Aliveness and Engineering: A Taxonomy of Fungal Engineered Living Materials

Advanced Materials, Volume 38, Issue 5, 22 January 2026.
This paper explores the potential of fungal engineered living materials (ELMs), examining fungal biology and growth mechanisms, which underpin their development. It presents a classification framework based on aliveness, scaffold composition, and engineering degree. Unique properties such as self‐healing, biosensing, and bioremediation are highlighted,

Gravitropism in plants: Hydraulics and wall growth properties of responding cells [PDF]

Gravitropism is the asymmetrical alteration of plant growth in response to a change in the gravity vector, with the typical result that stems grow up and roots grow down.

Optimized Laboratory Maintenance and Functional Testing of Chara braunii

Current Protocols, Volume 6, Issue 1, January 2026.
Abstract Chara braunii is an emerging model species for studying plant evolution and development. Various members of the Chara genus have been used for pioneering studies of electrophysiology, cytoplasmic streaming, and cell biology. However, many studies have been limited by challenges, such as overgrowth with epiphytes or non‐continuous growth ...
