Aconitum offers bees more nectar to carry its toxic pollen
Male flowers of Aconitum protect their pollen by adding alkaloids. Without pollen as a reward, botanists asked how the flower compensated pollinators.

Defence signalling marker gene responses to hormonal elicitation differ between roots and shoots
Plants responses to environmental stresses are regulated by signalling hormones, such as jasmonic acid, salicylic acid, ethylene and abscisic acid. Plant scientists commonly use marker genes to study which signalling...

Biomineralised barbed botanics bite back!
They almost literally bite. Glochidiate trichomes in some species of Loasa contain nanocrystalline apatite-cellulose composite, similar to the material found in teeth.

Defoliation, tree growth and storage of C and N
Although lenga beech trees, completely defoliated by caterpillars of Ormiscodes amphimone, do not die, they show reduced growth for at least 2 years.

COR, nice one, Mr Microbe!
Although open stomata are necessary for plants to take up CO2 for photosynthesis, this also permits loss of precious water – by transpiration, the so-called necessary evil of photosynthesis. But, surely, nothing worse...
