Plants grown at high densities perceive a decrease in the red to far-red (R:FR) ratio of incoming
light, resulting from absorption of red light by canopy leaves and reflection of far-red light …

There have been significant advances in our understanding of the effects of UV-B radiation
on terrestrial ecosystems, especially in the description of mechanisms of plant response. A …

Plants ‘forage' for light in plant canopies using a variety of photosensory systems. Far-red
radiation (FR) reflected by neighbours is an early signal of competition that elicits anticipatory …

… CL substrates exposed to solar radiation consistently demonstrated a reduction in lignin
concentration, whereas biotically incubated CL substrates overall showed increased lignin …

… Leone, MM Keller & CL Ballaré, unpublished observations). These results suggest that
the effects of low R:FR inhibiting JA responses in Arabidopsis are mediated by a reduction in …

… for higher plants of lower latitudes (Ballaré et al.; 14 Searles et al. )… Adapted from Austin and
Ballaré.93 (C) CO2 evolution from … Adapted from Austin and Ballaré. (C) CO 2 evolution from …

… with negative phototropic responses to reflected FR radiation (Ballaré et al. 1992), can help
plants to direct their growth toward canopy gaps in patchy canopies (Ballaré et al. 1995b; …

Colorless phenylpropanoid derivatives are known to protect plants from ultraviolet (UV)
radiation, but their photoregulation and physiological roles under field conditions have not been …

Light signals perceived by specific plant photoreceptors such as phytochromes, cryptochromes
and phototropin play a central role controlling the physiology and development of weed …

For plants, the tradeoff between resource investment in defense and increased growth to out-compete
neighbors creates an allocation dilemma. How plants resolve this dilemma, at the …
