Fungal pathogens such as Botrytis cinerea can cause devastating losses to agricultural crops – ask any strawberry, grape, or tomato grower. To prevent these losses, plants can summon a variety of immune responses by recognizing specific molecules associated with pathogen attack and/or internal damage. Pathogen damage to host tissues can result in production of endogenous […]

Cyclins and cyclin-dependent protein kinases (CDKs) are critical regulators of cell cycle progression. Although CDK1 is essential for mitosis in animals and fungi, CDKA, the plant and algal ortholog of CDK1, is not essential for cell division in Arabidopsis (Nowack et al., 2012). By contrast, CDKB is a plant-specific CDK. The high level of whole-genome […]
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 of biological functions (Tanaka and Tanaka, 2007; Brzezowski, et al., […]
Carbon and nitrogen metabolism are intricately linked in all organisms and are tightly regulated to maintain growth, homeostasis, and other cellular activities. In plants and algae, photosynthesis provides both carbon skeletons and the reductant needed for assimilation of inorganic NO3¯ by nitrate reductase (NR). NR catalyzes the conversion of nitrate (NO3¯) to nitrite (NO2¯), which […]
IN BRIEF by Gregory Bertoni email@example.com Proper localization of proteins in the plasma membrane is critical for proper functioning of plant cells, but the underlying mechanisms are poorly understood (Łangowski et al, 2016). This is especially true for transporter proteins that move necessary nutrients into and out of cells and organelles. For example, proper polar […]
