Significance: Reactive oxygen species (ROS), important signaling molecules in plants, are
involved in developmental control and stress adaptation. ROS production can trigger broad …

Species often include multiple ecotypes that are adapted to different environments.
However, it is unclear how ecotypes arise and how their distinctive combinations of adaptive …

Plants with altered microRNA metabolism have pleiotropic developmental defects, but direct
evidence for microRNAs regulating specific aspects of plant morphogenesis has been …

Plants grown under dense canopies perceive through the phytochrome system a reduction
in the ratio of red to far-red light as a warning of competition, and this triggers a series of …

Plant microRNAs (miRNAs) affect only a small number of targets with high sequence
complementarity, while animal miRNAs usually have hundreds of targets with limited …

Most plant microRNAs (miRNAs) have perfect or near-perfect complementarity with their
targets. This is consistent with their primary mode of action being cleavage of target mRNAs …

The plant hormones abscisic acid (ABA), jasmonic acid (JA), and ethylene are involved in
diverse plant processes, including the regulation of gene expression during adaptive …

The timing of the induction of flowering determines to a large extent the reproductive
success of plants. Plants integrate diverse environmental and endogenous signals to ensure …

Stomatal pores, formed by two surrounding guard cells in the epidermis of plant leaves,
allow influx of atmospheric carbon dioxide in exchange for transpirational water loss …

Wounding plant tissues initiates large-scale changes in transcription coupled to growth
arrest, allowing resource diversion for defense. These processes are mediated in large part …
