This Commentary, written by Emily Larson, is from the October issue of Plant Physiology. The spatial and temporal accumulation of auxins promotes and regulates polarized, gravitropic, and phototropic growth in plants. The proteins involved in initiating and maintaining the auxin gradients have been studied and remain active areas of research in the hormonal regulation of … Read more
Our understandings of the forces that have shaped Earth and the forces that have shaped life on Earth have common roots. Charles Darwin was famously inspired by the work of early geologists such as Charles Lyell, who proposed that Earth was subject to slow but gradual change. This idea recurs in Darwin’s insights about evolution … Read more
Chemical genetics is a powerful complement to conventional genetics. Rather than knocking out gene functions, protein (or other) functions can be perturbed through the addition of small molecules. One advantage is that several related proteins can be affected at the same time, avoiding the difficulties that come from genetic redundancy. Another is that treatment regimes … Read more
When is a flower not a flower? When it’s an inflorescence (cue laughter). Plants in the family Asteraceae produce inflorescences that look like single flowers, but are actually made up of hundreds of individual flowers. In many species, their are two types of flowers. The ray flowers (also known as ray florets) produce an elongated … Read more
The final major symposium of the Plant Biology 2016 conference was organized by ASPB President Richard Dixon and covered various aspects of specialized metabolism in plants (note that the term specialized metabolism has largely supplanted the older term secondary metabolism, which carries with it an implication that it is not as important as primary metabolism; … Read more
