CO2 and O2 as Drivers of Plant Macroevolution
Plant Physiology, Plant Physiology: On The InsideThe evolution of photosynthesis and, at a later point, the emergence of land plants resulted in substantial changes in the composition of Earth’s atmosphere. Plant colonization of the land in the early Paleozoic (more than 450 million years ago [mya]) was followed by a rapid drop in atmospheric [CO2],…
A Gene Affecting Chloroplast Size
Plant Physiology, Plant Physiology: On The InsideDuring leaf growth and development, chloroplast numbers increase to maximize photosynthetic capacity. In mesophyll cells, chloroplast division takes place primarily during cell expansion and increases plastid numbers from; 10 to 20 in leaf primordia to; 100 or more in mature mesophyll cells. Chloroplasts…
Acylsugar Metabolic Gene Network
Research, The Plant Cell, The Plant Cell: In a NutshellBy Sabyasachi Mandal
Department of Biology, Texas A&M University, College Station, USA
Background: Acylsugars are specialized metabolites secreted through the trichomes (plant hairs) of many plants in the nightshade family (Solanaceae). These compounds provide protection against herbivores…
Purple is the New Orange: Anthocyanin Regulation Coming Together in Carrot
Plant Physiology, Plant Physiology: News and Views, ResearchWestern cultivated carrot (Daucus carota subsp. sativus L) is broadly known for its orange pigmentation and accumulation of carotenoids, known as the carotene group (var. sativus). However, the eastern wild carrot (subsp. carota) originating from southwestern Asia over a century ago provides purple pigmentation…

Review: Exchange of small regulatory RNAs between plants and their pests (Plant Physiol)
Plant Science Research WeeklyTrans-species small RNAs are the latest class in the family of signals that move between plants and their attackers. Hudzik et al. review this topic, covering small RNAs that move from plant to pest and from pest to plant. The transmitted RNAs function by interfering with gene expression in the recipient.…
