Evolutionary history of plant microRNAs.
microRNAs (miRNAs) are short noncoding regulatory genes that perform important roles in plant development and physiology. With the increasing power of next generation sequencing technologies and the development of bioinformatic tools, there has been a dramatic increase in the number of studies surveying the miRNAomes of plant species, which has led to an explosion in the number of described miR...
متن کاملOrigin, Biogenesis, and Activity of Plant MicroRNAs
MicroRNAs (miRNAs) are key posttranscriptional regulators of eukaryotic gene expression. Plants use highly conserved as well as more recently evolved, species-specific miRNAs to control a vast array of biological processes. This Review discusses current advances in our understanding of the origin, biogenesis, and mode of action of plant miRNAs and draws comparisons with their metazoan counterpa...
متن کاملThe evolutionary-developmental analysis of plant microRNAs.
MicroRNAs (miRNAs) control many important aspects of plant development, suggesting these molecules may also have played key roles in the evolution of developmental processes in plants. However, evolutionary-developmental (evo-devo) studies of miRNAs have been held back by technical difficulties in gene identification. To help solve this problem, we have developed a two-step procedure for the ef...
متن کاملPlant polyploidy and the evolutionary ecology of plant/animal interactions
Until recently almost nothing was known about the effects of plant polyploidy on interactions with herbivores and pollinators. Studies of the saxifrage Heuchera grossulariifolia throughout its geographical range in the US northern Rockies have shown that autopolyploidy has probably arisen multiple times within this species since the end of the Pleistocene. Tetraploids from those different origi...
متن کاملThe role of microRNAs and phytohormones in plant immune system
The plant-pathogen interaction is a multifactor process that may lead to resistance or susceptible responses of plant to pathogens. During the arms race between plant and pathogens, various biochemical, molecular and physiological events are triggered in plant cells such as ROS signaling, hormone activation and gene expression reprogramming. In plants, microRNAs (miRNAs) are key post-transcript...
