Summary: This study investigates the effect of Rhizophagus irregularis on the expression of plasma membrane aquaporin isoforms in maize leaves under severe drought conditions. The findings show that the regulation of aquaporins by mycorrhiza is dependent on leaf position and is closely related to photosynthesis and stomatal response to drought. The results suggest that mycorrhiza protects the leaves from drought effects by preventing the down-regulation of aquaporins, leading to improved stomatal conductance and faster restoration of photosynthetic capability.

Summary: In this study, a member of the AP2/ERF transcription factor family, ZmEREBP60, was characterized in maize. ZmEREBP60 was found to be a positive regulator of plant drought response and regulates the expression of genes involved in H2O2 catabolism, water deprivation response, and abscisic acid signaling pathway.

Summary: The study identified an S-type anion channel ZmSLAC1 in maize guard cells that plays a crucial role in stomatal closure under drought stress, regulated by ZmCPK35 and ZmCPK37. Increasing the expression levels of ZmCPK35 and ZmCPK37 is a feasible approach to enhance maize drought tolerance and reduce yield loss under drought conditions.

Summary: A novel transcription factor gene ZmERF21 was identified to be closely associated with drought tolerance in maize seedlings, with overexpression leading to increased chlorophyll content and antioxidant enzyme activities. It may directly regulate the expression of genes related to hormone and Ca signaling to enhance drought tolerance in maize.

Summary: This study revealed that ZmNAC49 is induced by drought stress and overexpression can enhance stress tolerance in maize by reducing stomatal density. Additionally, ZmNAC49 directly binds to the promoter of ZmMUTE to suppress its expression, providing a mechanism for the enhanced drought tolerance observed.

Summary: In response to salt stress, plants regulate the expression of gene networks to survive and thrive. This study reveals that the ZmmiR169q/ZmNF-YA8 module plays a role in regulating the growth of maize taproots under salt stress, providing new insights into the molecular mechanism of plant development in response to salt stress.

Summary: The study aimed to identify maize hybrids with high and stable yields under different soil moisture regimes, conducting trials at seven test environments in two locations in India. Various methods including AMMI, GGE biplot, and MTSI were used to analyze the phenotypic stability of maize hybrids, with an emphasis on identifying genotypes with high stability and maximum yield potential. The methods employed were effective in identifying promising maize hybrids with high mean performance and greater phenotypic stability across different soil moisture conditions.

Summary: This study assessed the diversity among 22 maize inbreds using 18 microsatellite markers, and identified 187 alleles. The study found that the genetic diversity among maize inbreds is important for maize hybridization, and certain alleles have higher diversity. The study also identified markers that are most suitable for maize inbreds and can be used as parent materials for future hybrid maize breeding.

Summary: This study evaluated the impact of combined heat and water stress on maize yield and found that increasing water stress led to a decrease in yield. Organic soil amendments showed greater improvement in grain yield under the combined stress. Farmers are advised to grow drought-tolerant maize varieties WE5323 and ZM1523 with organic amendments in high-stress environments. The findings of this study could enhance food security strategies for low-income households in high-stress environments.
