Broadening Gene Pool of Rice for Resistance to Biotic Stresses Through Wide Hybridization
Variability in the cultivated germplasm for economic traits such as resistance to rice tungro virus, sheathblight, yellow stem borer, drought and salt tolerance is limited. This necessitated search for the genes in secondary and tertiary gene pool of genus Oryza. Fortunately, wild species are an important reservoir ofuseful genes for resistance to major disease, pest and tolerance t...
متن کاملPlant responses to environmental stresses—from gene to biotechnology
Increasing global population, urbanization and industrialization are increasing the rate of conversion of arable land into wasteland. Supplying food to an ever-increasing population is one of the biggest challenges that agriculturalists and plant scientists are currently confronting. Environmental stresses make this situation even graver. Despite the induction of several tolerance mechanisms, s...
متن کاملAdaptations to Environmental Stresses.
Environmental stresses come in many forms, yet the most prevalent stresses have in common their effect on plant water status. The availability of water for its biological roles as solvent and transport medium, as electron donor in the Hill reaction, and as evaporative coolant is often impaired by environmental conditions. Although plant species vary in their sensitivity and response to the decr...
متن کاملEvaluation of Resistance to Fluoroquinolones and Its Relationship whit parC Gene Mutation in Klebsiella pneumoniae Clinical Isolates
Background & Objective: Klebsiella pneumoniae has received attention due to a wide range of diseases and antibiotic resistance.The resistance to fluoroquinolones in gram-negative bacteria is often due to chromosomal mutations in the gyr and par genes. This research aimed at investigating the pattern of fluoroquinolone resistance and its relation with a mutation in the parC gene among clinical i...
متن کاملAging causes decreased resistance to multiple stresses and a failure to activate specific stress response pathways
In this work, we examine the relationship between stress resistance and aging. We find that resistance to multiple types of stress peaks during early adulthood and then declines with age. To dissect the underlying mechanisms, we use C. elegans transcriptional reporter strains that measure the activation of different stress responses including: the heat shock response, mitochondrial unfolded pro...
