Strigolactones spatially influence lateral root development through the cytokinin signaling network [PDF]

, 2015
Strigolactones are important rhizosphere signals that act as phytohormones and have multiple functions, including modulation of lateral root (LR) development.

Root tip excision‐induced exodermis lignification impacts lateral root emergence in Brachypodium distachyon

New Phytologist, EarlyView.
Summary The mechanisms controlling lateral root emergence in monocots, particularly the role of the exodermis, are poorly understood. We investigated how natural variation in the Brachypodium distachyon stress response shapes root system architecture by modulating cell wall dynamics.

The plant hormone ethylene restricts Arabidopsis growth via the epidermis [PDF]

, 2018
The gaseous hormone ethylene plays a key role in plant growth and development, and it is a major regulator of stress responses. It inhibits vegetative growth by restricting cell elongation, mainly through cross-talk with auxins.

Symbiosis‐associated UMAMIT transporters required for establishing efficient nitrogen fixation in Medicago truncatula

New Phytologist, EarlyView.
Summary To address a critical gap in understanding amino acid transport in legume–Rhizobium symbiosis, we investigated the role of symbiosis‐associated USUALLY MULTIPLE ACIDS MOVE IN AND OUT TRANSPORTERS (UMAMITs) in Medicago truncatula nodulation.

EARLY STARVATION 1 Is a Functionally Conserved Protein Promoting Gravitropic Responses in Plants by Forming Starch Granules

Frontiers in Plant Science, 2021
Starch granules in the endodermis of plant hypocotyls act as statoliths that promote hypocotyl negative gravitropism—the directional growth of hypocotyls against gravity—in the dark.

Strigolactones Regulate Sugar Allocation to Control Rice Tillering and Root Development via the OsSPL14‐OsSHR1‐OsSWEET16 Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT Strigolactones (SLs) are root‐to‐shoot phytohormones that regulate tillering (branching) and root development. Sugar, as an essential energy substance and signalling molecule, plays a fundamental role in the growth and development of plants. However, the molecular mechanisms by which SL directly regulates sugar allocation to control tillering ...

Cell‐Type‐Specific and Variety‐Specific Responses to Salt Stress in Wheat Root Revealed by Single‐Cell Transcriptomics

Plant Biotechnology Journal, EarlyView.
ABSTRACT Soil salinization threatens the yield and quality of wheat. Roots are critical for the salt stress response, yet their cell‐type‐specific mechanisms remain unclear. We conducted the first single‐nucleus RNA sequencing analysis of wheat root tips from salt‐sensitive (CS) and ‐tolerant (DK) varieties under salt stress, profiling 188 270 high ...

Mutation in the pssZ Gene Negatively Impacts Exopolysaccharide Synthesis, Surface Properties, and Symbiosis of Rhizobium leguminosarum bv. trifolii with Clover [PDF]

, 2018
Rhizobium leguminosarum bv. trifolii is a soil bacterium capable of establishing a nitrogen-fixing symbiosis with clover plants (Trifolium spp.). This bacterium secretes large amounts of acidic exopolysaccharide (EPS), which plays an essential role in ...

Enhanced CO2 Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient‐efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low‐nitrogen ...
