Unlabelled: Maize kernel protein is deficient in sulfur-containing essential amino acid such as methionine. The gene encodes methionine-rich 18-kDa δ-zein in maize kernels. In this study, we sequenced full-length of gene (820 bp) among 10 maize inbreds, revealing 43 SNPs and 22 (average length-7.

- Maize oil is increasingly in demand for various industries, highlighting the need for sustainable production methods.
- Researchers evaluated 48 maize genotypes with different genetic traits across three locations to analyze their oil content and fatty acid profiles.
- Double-mutant genotypes showed significantly improved oil content and healthier fatty acid profiles compared to wild-types, suggesting they could provide health benefits and support maize breeding programs to meet market demands.
Popcorn is a specialty corn with worldwide popularity as a snack. Despite having great market demand, genetic improvement in popping quality is limited, which is caused by the limited germplasm utilization and narrow genetic base. An assortment of diverse germplasm, their effective characterization, and integration into popcorn breeding pipeline is the foundation for an efficient breeding program.

- Popcorn is a key crop for both India and the global economy, but breeding efforts are limited due to its narrow genetic diversity, necessitating imports.
- This study involved crossing various inbred strains with superior popcorn hybrids to evaluate traits like popping quality and grain yield across different regions in India, highlighting significant genetic variation.
- Results indicated specific genetic combinations that excelled in both popping quality and yield, suggesting future breeding strategies that combine beneficial traits to achieve sustainable popcorn production.
Article Synopsis
- * The study analyzed both wild and mutant alleles' expression in maize inbreds at various stages of kernel development, finding a 29.30% reduction in phytic acid in mutant inbreds, along with significantly higher levels of lysine, tryptophan, and provitamin-A.
- * Results highlighted positive correlations between phytic acid and transcript levels while showing negative correlations with nutrient levels, marking this as the first detailed study on these gene expressions in maize across different
Article Synopsis
- The embryo in maize plays a crucial role in determining kernel-oil content, which is directly linked to the calorific value of the maize kernel.* -
- A genetic study involving six generations of three maize crosses was conducted to analyze traits related to embryo size and weight, revealing significant interactions and the importance of dominance effects in trait inheritance.* -
- The results suggest a quantitative inheritance pattern for the traits studied, highlighting the potential for using breeding methods like heterosis to enhance embryo traits and, consequently, kernel-oil content in maize.*
