Homeoprotein DNA-binding specificity
... "Our studies go a long way towards unraveling the mystery of how homeoproteins can find their target genes in vivo and, in addition, help pus to understand how the "address" of a gene in the nucleus contributes to its differential regulation."...Does tropical biodiversity increase as rainforest area expands during global warming?
...s the planet warms and decreases as it cools. The mystery is that even when global temperatures vary enormously, average temperatures in the tropics don't change much, so why do we see global temperature patterns reflected in tropical plant diversity?"
