Crop Ecology and Plant Breeding for Disease Resistance

Mutagenesis in Plant Breeding for Disease and Pest Resistance

Plant hormone interactions: innovative targets for crop breeding and management.

Here we highlight how both the root and shoot environment impact on whole plant hormone balance, particularly under stresses such as soil drying, and relate hormone ratios and relative abundances to processes influencing plant performance and yield under both mild and more severe stress. We discuss evidence (i) that abscisic acid (ABA) and ethylene act antagonistically on grain-filling rate amo...

Plant breeding: Induced mutation technology for crop improvement

present forms of life are the product of three factors: • mutation, the fundamental source of heritable variation, • environmental factors, which influence the selection of those mutations that survive and reproduce, and • time, during which the genotype and environment constantly interact and evolutionary change is realized. Genetic variation found in nature does not represent the original spe...

Molecular Breeding Strategy and Challenges Towards Improvement of Blast Disease Resistance in Rice Crop

Rice is a staple and most important security food crop consumed by almost half of the world's population. More rice production is needed due to the rapid population growth in the world. Rice blast caused by the fungus, Magnaporthe oryzae is one of the most destructive diseases of this crop in different part of the world. Breakdown of blast resistance is the major cause of yield instability in s...
