Scientists find that common floral compounds become more toxic to butterflies at higher temperatures, complicating projections of climate change impacts.
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...
They almost literally bite. Glochidiate trichomes in some species of Loasa contain nanocrystalline apatite-cellulose composite, similar to the material found in teeth.
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...
