SEED HYDROPRIMING TECHNIQUE IN CEREAL CROPS: A REVIEW

Recent advances in molecular tool development for drought tolerance breeding in cereal crops: a review

Drought stress is one of the major yield constraints for cereal crops. Traditionally, for developing drought tolerant cultivars, selection either direct or indirect is practiced. Although this approach is effective, yet time consuming and labour intensive. Identification of drought related quantitative trait loci (QTLs) coupled with marker assisted selection has shown some positive results. Tra...

Cereal Seed Germination under Anoxia

The great majority of seeds from higher plants fail to germinate under anoxic conditions. While the metabolic pathways operating during the aerobic process of seed germination are well described, there is only limited evidence concerning metabolic pathways operating under conditions of limited oxygen availability. This is despite the importance of carbohydrate availability for plant tolerance t...

Genetic transformation of major cereal crops.

Of the more than 50,000 edible plant species in the world, at least 10,000 species are cereal grains. Three major cereal crops, rice (Oryza sativa), maize (Zea mays), and wheat (Triticum sp.), provide two-thirds of the world's food energy intake. Although crop yields have improved tremendously thanks to technological advances in the past 50 years, population increases and climate changes contin...

Relationships of cereal crops and other grasses.

The grass family includes some 10,000 species, and it encompasses tremendous morphological, physiological, ecological, and genetic diversity. The phylogeny of the family is becoming increasingly well understood. There were two major radiations of grasses, an early diversification leading to the subfamilies Pooideae, Bambusoideae, and Oryzoideae, and a later one leading to Panicoideae, Chloridoi...
