Drought and salinity stress remodel Asian rice (Oryza sativa) leaf development through cell‐type‐specific regulatory programs

open access: yesNew Phytologist, EarlyView.
Osmotic stressors induce developmental and physiological changes in rice (Oryza sativa) seedlings, which are modulated by cell‐type‐specific gene expression and regulatory networks. We exposed plants to two levels of drought and salinity stress and measured the effects of these stressors on developing leaves by measuring physiological traits, ion ...

THE KEY ROLE OF PIN PROTEINS IN AUXIN TRANSPORT IN ARABIDOPSIS THALIANA ROOTS

open access: yesВавиловский журнал генетики и селекции, 2015
The phytohormone auxin is the key factor in plant morphogenesis. Being unevenly distributed in plant tissues, it forms gradients and concentration maxim а, according to which cells grow, divide, and differentiate. The family of PIN-FORMED (PIN) proteins,

The Slow Growth of Adventitious Roots in Tetraploid Hybrid Poplar (Populus simonii × P. nigra var. italica) May Be Caused by Endogenous Hormone-Mediated Meristem Shortening

open access: yesPlants
Polyploidization produces abundant phenotypic variation. Little is currently known about adventitious root (AR) development variation due to polyploidization.

The roads most traveled: genetic convergence in plant repeated evolution

open access: yesNew Phytologist, EarlyView.
Observation of a genotype–phenotype association in a focal lineage (magnifying lens) provides a starting point for predicting homolog reuse during repeated trait evolution. This review suggests that the likelihood that mutations in homologous genes contribute to similar phenotypes in other lineages depends on both mutational effect stability (MES) and ...

microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha

open access: yesNew Phytologist, EarlyView.
The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

Nodulation does not alter root hydraulic conductance in pea

open access: yesNew Phytologist, EarlyView.
Root hydraulic conductance (Kr) normalised by root dry mass (including nodules) under hydrated and drought conditions in Pisum sativum wild‐type (Frisson, Nod+), non‐nodulator (sym19, Nod−), and supernodulator (Psrdn1, Nod++).

Evaluation of a novel laser-system operating at 1940 nm for weed control and determining the influence of biological and operational factors. [PDF]

open access: yesPest Manag Sci
The control efficacy of a novel laser pulse system operating at 1940 nm was tested. The new system allows effective control of young weeds with 1.5 J. Targeting the plant stem is 53‐fold more energy‐efficient than the meristem. Species morphology and beam diameter significantly influence weed control efficacy. Abstract BACKGROUND This study evaluates a

Functional memory of drought affects leaf chemical defenses and microbial interactions in aspen

open access: yesNew Phytologist, EarlyView.
Experimental design of the common garden study. Summary Drought is an important driver of tree mortality, but its long‐term impacts on trait expression remain poorly understood. Leaves are a key interface at which trees respond to abiotic stress, and foliar traits such as chemical defenses and microbial communities may play a role in determining post ...

Linking drought strategy to climate‐of‐origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

open access: yesNew Phytologist, EarlyView.
Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

Coordination of drought‐adaptive root growth plasticity through auxin homeostasis by the ZmSPL12–ZmYUC5 module in maize

open access: yesNew Phytologist, EarlyView.
Proposed model of ZmSPL12‐mediated drought resistance through auxin regulation. Summary Climate change‐induced drought increasingly threatens global maize production. Drought‐adaptive root plasticity in maize depends on auxin signaling, yet how auxin homeostasis is dynamically tuned in response to water deficit remains unclear.
