Plant growth and development are extremely adaptable to changes in the external environment, including nutrient status, light quality and intensity, and temperature. Thanks to their developmental plasticity, plants can also initiate new organs from differentiated tissue following wounding, to the benefit…

The energetically costly tendency of the carbon fixing enzyme RuBisCO to, every now and then, fix oxygen instead of carbon dioxide has led to the evolution of various carbon concentrating mechanisms in plants and algae. One such mechanism, Crassulacean acid metabolism (CAM), involves primary CO2 fixation…

Aphids are highly destructive insect pests—in addition to robbing plants of sugar-rich phloem sap, they carry viruses that can be deadly to the plant. To reach the phloem sap, aphids must penetrate the plasma membrane of sieve elements. Mature sieve elements, which are virtually empty, translocate…

A hallmark of xylem development is the deposition of secondary cell wall material in specific patterns (reviewed in Patrick et al, 2007). These cell wall deposits structurally reinforce the xylem to withstand negative pressure during water transport and differ in different xylem cell types. While it…

We all know that DNA is the stable nucleic acid, in comparison to its flighty, unstable cousin RNA, right? Well, unusual things happen when metabolic processes require DNA to unwind from its stable, redundant double-helical form. For example, during transcription, the RNA that exits RNA polymerase can…

Folates are soluble B9 vitamins with essential functions in all kingdoms of life—both in organisms that produce these vitamins de novo (fungi, plants, and most microorganisms) and in those that do not (animals). As essential cofactors in one-carbon transfers, different folate species mediate the biosynthesis…

Sabeeha Merchant, Editor-in-Chief of The Plant Cell, recently spent a week in China meeting with Chinese scientists at SIPPE  (Shanghai Institute of Plant Physiology and Ecology) and FAFU (Fujian Agriculturlal and Forstry University) to learn about their research. She emphasized the power of technology…
