A look at the leaf anatomy of an unusual freshwater aquatic
The plant has a unique arrangement for carrying out C4 photosynthesis without the typical C4 anatomy.

New grapevine model better predicts whole-canopy gas exchange
Models considering only the maximum photosynthetic capacity for all leaves over-estimated net carbon dioxide exchange by nearly a third.
Complex interplay of responses when plants experience canopy shading
Plants react to both decreased red:far red ratio and decreased photosynthetically active radiation, and in different ways.
X-ray dose limits for microscopy lower than we thought
Subtle damage to hydrated tissue occurs at a far lower dosage than previously thought, and may be difficult to recognize.
Males become female when striped maples take a health hit
Above a certain trauma threshold, male trees had a high probability of becoming female, possibly in a bid to better their chances at reproduction.
European white oak hybrids can be well-identified with a small set of genetic markers
A limited set of SNPs identified the species of test trees with a high degree of accuracy, finding asymmetrical mixing among the three species.
Leaf trichomes may avoid water stress in part by impeding gall formation
Trichomes seem to help prevent the larger gall types that lead to greater water loss.
Botanists explore how mint makes a home for ants and mites
Domatia in a member of the mint family are caused by cell proliferation, not leaf rolling
Delayed aluminium exclusion in signal grass is energy-dependent
The mechanism requires a day or two from exposure to exclude the metal from the intracellular compartment.
