Transcriptional activation of rice CINNAMOYL-CoA REDUCTASE 10 by OsNAC5, contributes to drought tolerance by modulating lignin accumulation in roots

Seung Woon Bang et al.

Summary: Research has shown that the rice gene OsCCR10 is directly activated by the transcription factor OsNAC5, mediating drought tolerance through lignin accumulation. Overexpression of OsCCR10 in transgenic rice plants results in improved drought tolerance and higher lignin content, while knockout mutants exhibit reduced lignin accumulation and drought tolerance. Transgenic rice plants with root-preferential overexpression of OsCCR10 also show higher grain yield under field drought conditions, indicating the importance of lignin biosynthesis in drought tolerance.

GABA-mediated inhibition of cadmium uptake and accumulation in apples

Yuxing Li et al.

Summary: GABA plays an important role in alleviating heavy metal cadmium (Cd) toxicity in apple seedlings. Exogenous GABA reduces the net Cd2+ fluxes in apple roots, decreases Cd content, and inhibits the expression of Cd uptake and transport-related genes. Additionally, it increases amino acid content in apple roots under Cd stress. Transgenic apple roots overexpressing MdGAD1 show lower Cd accumulation, reduced Cd uptake, and lower expression of transport-related genes.

Polyamines Metabolism Interacts with γ-Aminobutyric Acid, Proline and Nitrogen Metabolisms to Affect Drought Tolerance of Creeping Bentgrass

Meng Tan et al.

Summary: Due to global warming and climate change, drought poses a serious threat to horticultural crop cultivation. The study found that pretreatment with spermine (Spm) significantly improved drought tolerance in creeping bentgrass. The Spm pretreatment increased the accumulation of endogenous PAs, enhanced PAs metabolism, improved GABA and nitrogen metabolism, and regulated the TCA cycle, contributing to better drought tolerance. The study provides a comprehensive understanding of PAs interaction with other metabolic pathways in regulating drought tolerance in grass species.

Exogenous γ-aminobutyric acid (GABA)-induced signaling events and field performance associated with mitigation of drought stress in Phaseolus vulgaris L

Hany G. Abd El-Gawad et al.

Summary: Limited information is available to support the potential role of GABA signaling in alleviating water-deficit stress in snap bean plants under semiarid conditions. This study investigates the impact of exogenous GABA application on drought stress alleviation and field performance improvements in snap bean plants subjected to different irrigation levels. Results indicate that GABA application, especially at 2 mM, partially mitigates the effects of drought stress by improving growth, water status, membrane integrity, osmotic adjustment, antioxidant defense, and nutrient acquisition, leading to increased pod yield and quality attributes.
