Photosynthetic, antioxidant activities, and osmoregulatory responses in winter wheat differ during the stress and recovery periods under heat, drought, and combined stress

Chen Ru et al.

Summary: There will be longer and more intense periods of heat and drought stress in the future for terrestrial ecosystems. This study investigated the responses of wheat plants to heat and drought stress and their recovery after stress relief. The results showed that while most physiological processes were reversible after stress relief, some irreversible damage was caused by combined heat and drought stress.

Cowpea NAC1/NAC2 transcription factors improve growth and tolerance to drought and heat in transgenic cowpea through combined activation of photosynthetic and antioxidant mechanisms

Richa Srivastava et al.

Summary: NAC transcription factors play important roles in growth and stress responses in plants, but the conservation of function and regulatory targets varies between species, making them unsuitable for pulse engineering. In this study, overexpression of two native NAC genes (VuNAC1 and VuNAC2) in cowpea improved growth and conferred multiple abiotic stress tolerance. The transgenic plants showed increased leaf area, thicker stem, dense root system, early flowering, higher pod production, and greater seed weight. In contrast, suppression of VuNAC1/2 resulted in growth retardation and flower inhibition.

Expression of ZmNAGK in tobacco enhances heat stress tolerance via activation of antioxidant-associated defense

Weijuan Liu et al.

Summary: In this study, a maize gene (ZmNAGK) was identified to enhance the heat stress tolerance in plants. ZmNAGK expression was up-regulated in response to heat stress and localized in chloroplasts. Overexpression of ZmNAGK in tobacco increased heat tolerance by activating antioxidant defense signaling and regulating the expression of antioxidant-enzyme encoding genes and heat shock network genes.

Arabidopsis plants overexpressing additional copies of heat shock protein Hsp101 showed high heat tolerance and endo-gene silencing

Richa Babbar et al.

Summary: Hsp101 is essential for plant survival under heat stress. Transgenic Arabidopsis lines with extra copies of Hsp101 gene were generated using different methods. Arabidopsis plants transformed with rice Hsp101 cDNA driven by Arabidopsis Hsp101 promoter showed high heat tolerance, while those transformed with rice Hsp101 cDNA driven by CaMV35S promoter had a similar response to heat stress as wild type plants. The over-expressor lines of Hsp101 showed enhanced heat tolerance, while the under-expressor lines were overly heat sensitive.

Plant flavonoids: Classification, distribution, biosynthesis, and antioxidant activity

Nan Shen et al.

Summary: Flavonoids are natural polyphenol substances abundant in various plant-based foods. They have significant biological activities in both plants and humans, such as antioxidant, antimicrobial, and anti-inflammatory effects. However, research on their distribution, biosynthesis, and health benefits remains limited. Future opportunities in flavonoid research include biotechnology, therapeutic phytoproducts, and exploring dietary flavonoid bioavailability.

Systematic analysis of the non-specific lipid transfer protein gene family in Nicotiana tabacum reveal its potential roles in stress responses

Yongxia Yang et al.

Summary: This study systematically analyzed the gene structure, expression patterns, and function of the nsLTP family in plants. The results showed that different types of nsLTP genes have similar intron/exon patterns and conserved motifs. Purifying selection and segmental duplication played major roles in the expansion of this gene family. NtLTP family genes are involved in plant growth and development, and in response to abiotic and biotic stresses.

NtRAV4 negatively regulates drought tolerance in Nicotiana tabacum by enhancing antioxidant capacity and defence system

Yun Gao et al.

Summary: In this study, a new plant transcription factor NtRAV4 was discovered, which is involved in maintaining the steady state of plants under drought stress by enhancing antioxidant capacity and defense system. Knockout of NtRAV4 in tobacco plants resulted in increased drought tolerance and reduced levels of ROS, accompanied by higher antioxidant enzyme activities.

Growth and physio-biochemical responses of maize (Zea maysL.) to drought and heat stresses

Madiha Ayub et al.

Summary: The study indicates that drought stress predominates over heat stress, and the combination of drought and heat stress has significant adverse effects on maize growth and biochemical traits. Tolerant genotypes exhibit higher levels of proline, TSP, TSS, and TFAA content, making them suitable for breeding for adaptation to drought and heat under climate change.

A Lipid Transfer Protein has Antifungal and Antioxidant Activity and Suppresses Fusarium Head Blight Disease and DON Accumulation in Transgenic Wheat

John E. McLaughlin et al.

Summary: The study demonstrated that overexpression of the AtLTP4.4 gene in transgenic wheat significantly reduced the growth of Fusarium graminearum and decreased fungal lesion size. It also showed that the accumulation of DON was reduced in transgenic wheat plants overexpressing AtLTP4.4, possibly through the inhibition of oxidative stress.

Novel non-specific lipid-transfer protein (TdLTP4) isolated from durum wheat: Antimicrobial activities and anti-inflammatory properties in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages

Anis Ben Hsouna et al.

Summary: The study identified a novel gene TdLTP4 encoding an antifungal protein from wheat and demonstrated its antimicrobial properties against various pathogens, food-borne and spoilage bacteria, and fungi. The TdLTP4 fusion protein showed significant activity in inhibiting the production of inflammatory cytokines in LPS-stimulated macrophages through the modulation of iNOS and COX-2 expression. Overall, TdLTP4 has the potential to serve as a natural anti-inflammatory and antimicrobial agent for both food preservation and human health.

Differential variations in total flavonoid content and antioxidant enzymes activities in pea under different salt and drought stresses

Muhammad Farooq et al.

Summary: This study focused on evaluating the harmful effects of salt and drought stresses on three pea varieties, showing that high stress levels of both salt and drought led to a significant increase in total flavonoid content and enhanced activity of antioxidant enzymes in pea plants. Total flavonoid content and GPX showed a positive correlation with increased accumulation under salt and drought stress, indicating their main role in antioxidant activities.
