Nuclear accumulation of DELLA proteins induces transcriptional reprogramming and is well known to suppress the gibberellin (GA) pathway. While DELLAs can negatively regulate GA, increased GA levels can also signal DELLA degradation. GA is a growth-regulating hormone that is also involved in inhibiting…

Pollen cells have a fascinating ability to transform from a small spherical cell to a very elongated shape known as the pollen tube (PT) during fertilization. Pollen cells must navigate through the female tissue, find an ovary, and burst to release the two sperm cell nuclei as well as the vegetative…

Plants have two major ways of dealing with drought stress. First, when water levels are low, the phytohormone abscisic acid (ABA) induces stomatal closure. Soon after, growth, flowering, and fruit development take a back seat to plant survival. This suppressed growth is mediated by decreased activity…

The C-terminal domain (CTD) of RNA polymerase II (Pol II) extends from the catalytic core and consists of repeats of a seven-amino acid motif. The CTD functions in the regulation of Pol II function and is subject to just about every protein modification you can think of, including methylation, acetylation,…

The assassin who injects a bead of poison by stabbing his victim with the tip of his umbrella has got nothing on plant pathogenic bacteria such as Pseudomonas syringae, which injects dozens of effector proteins into plant cells. These effectors act as tiny assassins to take out host defenses by diverse…

What do photosynthesis, neonatal jaundice, and a next-generation solar cell have in common? All involve tetrapyrroles, complex molecules with four linked pyrrole rings, each ring containing one nitrogen and four carbon atoms. Tetrapyrroles exist in either cyclic or linear form and have a wide variety…

The next generation of next-generation sequencing is upon us. Third-generation sequencing aims to provide long stretches of sequence – ultimately to the chromosome level – at bargain basement prices. Progress is being made toward those goals with the emergence of long-read sequencing techniques and…
