BACKGROUND AND AIMS Competition drives self-thinning (density-dependent mortality) in crowded plant populations. Facilitative interactions have been shown to affect many processes in plant populations and communities, but their effects on self-thinning trajectories have not been investigated. METHODS Using an individual-based 'zone-of-influence' model, we studied the potential effects of the ...
Abiotic stresses elicit complex cellular responses. This complexity made many believe for a long time that tolerance to abiotic stresses cannot be experimentally manipulated. Fortunately, this contention has proven wrong in recent years. Considered once to be an arduous task, genetic engineering for increasing tolerance to abiotic stresses has been achieved to an extent. This change has come du...
Over 13% of all genes in the Arabidopsis thaliana genome encode for proteins classified as having a completely unknown function, with the function of >30% of the Arabidopsis proteome poorly characterized. Although empirical data in the form of mRNA and proteome profiling experiments suggest that many of these proteins play an important role in different biological processes, their functional ch...
The development of stress-tolerant crops is an increasingly important goal of current crop breeding. A higher abiotic stress tolerance could increase the probability of introgression of genes from crops to wild relatives. This is particularly relevant to the discussion on the risks of new GM crops that may be engineered to increase abiotic stress resistance. We investigated abiotic stress QTL i...
Abiotic stresses such as drought, salt, high temperature, chemical toxicity and oxidative stress are considered serious to agriculture and adversely affect the growth and reproduction of crops. Production of transgenic rice was studied utilizing Agrobacterium-mediated strain EHA105 and p6-ubi vector. This vector contains spectinomycin resistance gene as bacterial selectable marker, hygromycin...
Abiotic stress is one of the main problems affecting agricultural losses, and understanding the mechanisms behind plant tolerance and stress response will help us to develop new means of strengthening fruitful agronomy. The mechanisms of plant stress response are complex. Data obtained by experimental procedures are sometimes contradictory, depending on the species, strength, and timing applied...
Abiotic stress conditions such as drought, heat, or salinity cause extensive losses to agricultural production worldwide. Progress in generating transgenic crops with enhanced tolerance to abiotic stresses has nevertheless been slow. The complex field environment with its heterogenic conditions, abiotic stress combinations, and global climatic changes are but a few of the challenges facing mode...
