Shifting DNA markings
Markings on the DNA help plant cells ‘remember’. Who they are. In what developmental stage they are. Their environment. Now a new study in Communications Biology by Chinese researchers shows that during the early stages of embryo development these DNA marks shift frequently.
Hooked hairs
Sometimes when you look closely at something, you see something new. That is what a group of American researchers found when they looked closely at bean seedlings. In Science Advances they report about the up until now unknown hooked hairs on these seedlings.
Closing the trap
Carnivorous sundews actively capture their prey. But in contrast to the related Venus flytraps, sundews are not responding to touch or other mechanical stimulants. Now Chinese researchers show that a small peptide, glutathione, likely released by the captured fly, signals for the trap to close.
