Plant Biology Turning Over a New Leaf
In plant development, the growing shoot changes from a juvenile, or reproductively incompetent state, to an adult state. Mechanisms governing this change were examined by Berardini et al., who found that a protein termed squint, a chaperone-like protein, was involved. In mutants lacking squint protein, leaves exhibited adult properties early, but flowering time was unaffected. It was surprising that the mutant plants expressed elevated levels of another heat shock chaperone protein, Hsp90, but the response of seedlings to heat shock was not affected.
