Plant genomes in contrast to animal genomes don’t contain regulatory elements, or so was I led to believe. Now a new study “Two deeply conserved non-coding sequences control PLETHORA1/2 expression and coordinate embryo and root development” shows that plants also have those gene regulatory elements.

Sweet duplication
Sweet duplication Some flowers have a specific hollow outgrowth wherein they store their nectar, a so called nectar spur. How these evolved is often a mystery. Now Colombian researchers show in the journal Annals of Botany that it might be the result of a gene duplication. Flowers of Tropaeolum longifolium can only be divided inContinue reading “Sweet duplication”
Nighttime chills
Dampening the effects of nighttime chills Plants respond strongly to cold during the day. While night time chilling only gets a mild response. Now researchers from the University of Galsgow show in the New Phytologist how alternative splicing of REVEILLE2 dampens the effect of nighttime chill. The circadian clock regulates many aspects of a plantContinue reading “Nighttime chills”
Double break
Double break One of a seedlings first reactions to salt is stepping on the break. Now researchers from Scotland and Italia show in the New Phytologist how the protein HDC1 is regulating how hard the plant is pressing this break. To make sure that stress genes are not accidentally turned on they are decorated byContinue reading “Double break”
