Auxin‐Producing Pseudomonas Recruited by Root Flavonoids Increases Rice Rhizosheath Formation through the Bacterial Histidine Kinase Under Soil Drying

open access: yesAdvanced Science, EarlyView.
Drought is a major cause of crop losses across agricultural regions. Rhizosheath formation enhances plant resistance to drought. Polyploids may tolerate stress more effectively through increased interactions with bacteria. However, the contributions of tetraploid rice associated microbiota to rhizosheath formation under soil drying remain unclear ...

Drought-Tolerant Corn Hybrids Yield More in Drought-Stressed Environments with No Penalty in Non-stressed Environments [PDF]

open access: yesFrontiers in Plant Science, 2016
The potential benefit of drought-tolerant (DT) corn (Zea mays L.) hybrids may depend on drought intensity, duration, crop growth stage (timing), and the array of drought tolerance mechanisms present in selected hybrids. We hypothesized that corn hybrids containing DT traits would produce more consistent yields compared to non-DT hybrids in the presence

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa

open access: yesAdvanced Science, EarlyView.
Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

Non-contacting techniques for plant drought stress detection [PDF]

open access: yes, 2008
Plant drought stress indicators such as crop water stress index (CWSI), plant motion in the form of covariance of top-projected canopy area (COV_TPCA), leaf water content represented as equivalent water thickness (EWT), and their threshold values for ...

Potential of elite maize composites for drought tolerance in stress and non-drought stress environments

open access: yesAfrican Crop Science Journal, 2002
(Received 11 December, 1999; accepted 11 November, 2001) ABSTRACT Drought stress is a major factor limiting the productivity of maize (Zea mays L.) in West and Central Africa. This study was conducted to assess drought tolerance/susceptibility in nine early maturing maize composites, including five drought tolerant selections.

TaPPR13, a Pentatricopeptide Repeat Protein Gene Activated by TaBZR2, Confers Drought Stress Tolerance by Enhancing the Antioxidant Defense System and Promoting Retrograde Signaling in Wheat (Triticum aestivum)

open access: yesAdvanced Science, EarlyView.
TaPPR13, a PPR protein family gene in wheat is activated by TaBZR2 to enhance drought stress tolerance and photosynthetic capacity. It achieves this by interacting with TaAOR1 and TaSIG5 to improve antioxidant defense and regulate chloroplast gene expression. Abstract The wheat (Triticum aestivum) brassinazole‐resistant 2 (TaBZR2) gene is identified as

Development and Breeding of Herbicide‐Resistant Sorghum for Effective Cereal‐Legume Intercropping

open access: yesAdvanced Science, EarlyView.
This study identified two SbALS mutations (A93T and S624N) conferring robust herbicide resistance in sorghum, facilitating efficient weed control. Structural analysis revealed that imazamox resistance is mediated by disrupted herbicide binding. Furthermore, 126 imazamox resistant soybean varieties are screened for sorghum‐soybean intercropping ...
