Abstract:
... Zea mays ssp. parviglumis is the progenitor of maize and assume to have tolerance against various biotic and abiotic stresses. It grows without human intervention in Southern Mexico at the bank of Balsas river and maintains sufficient genetic diversity that can help in maize diversification and domestication of wild alleles. To develop the uniform near to homozygous line the maize inbred parent DI ...

Abstract:
... Interspecific hybridization with ‘Satputia’ (bisexual and cluster bearing) can be highly useful for the introgression of cluster bearing, high yield and gynoecism in sponge gourd (monoecious and solitary bearing). However, the occurrence of self-pollination in closed flowers and anthesis of two species at different time intervals creates hindrance in interspecific hybridization. The present invest ...

Abstract:
... Cellulose synthases (CesAs) are multi-subunit enzymes found on the plasma membrane of plant cells and play a pivotal role in cellulose production. The cotton fiber is mainly composed of cellulose, and the genetic relationships between CesA genes and cotton fiber yield and quality are not fully understood. Through a phylogenetic analysis, the CesA gene family in diploid Gossypium arboreum and Gossy ...
