Plant sex and the evolution of plant defenses against herbivores.
Despite the importance of plant-herbivore interactions to the ecology and evolution of terrestrial ecosystems, the evolutionary factors contributing to variation in plant defenses against herbivores remain unresolved. We used a comparative phylogenetic approach to examine a previously untested hypothesis (Recombination-Mating System Hypothesis) that posits that reduced sexual reproduction limit...
متن کاملNonhost resistance and nonspecific plant defenses.
In the past year, most of the advances in our understanding of nonhost resistance to plant pathogens have been incremental. Highlights include the discovery of a general bacterial elicitor of plant defenses, the description of more similarities between the hypersensitive response and animal programmed cell death, and a growing appreciation of the cell wall as the site of initiation and expressi...
متن کاملTimely plant defenses protect against caterpillar herbivory.
A s sessile, photosynthetic organisms, plants benefit greatly from a circadian clock that adjusts their overall metabolism in anticipation of the highly predictable arrival of sunrise and sunset. Thus, it is not surprising that about one-third of all plant genes show evidence of circadian regulation in their expression patterns (1, 2). However, closer examination of this diurnally regulated tra...
متن کاملMicroarray analysis of gene expression in medicinal plant research.
Expression profiling analysis offers great opportunities for the identification of novel molecular targets, drug discovery, development, and validation. The beauty of microarray analysis of gene expression is that it can be used to screen the expression of tens of thousands of genes in parallel and to identify appropriate molecular targets for therapeutic intervention. Toward identifying novel ...
متن کاملCoordinated plant defense responses in Arabidopsis revealed by microarray analysis.
Disease resistance is associated with a plant defense response that involves an integrated set of signal transduction pathways. Changes in the expression patterns of 2,375 selected genes were examined simultaneously by cDNA microarray analysis in Arabidopsis thaliana after inoculation with an incompatible fungal pathogen Alternaria brassicicola or treatment with the defense-related signaling mo...
