An Ion Channel Active in Plant Drought Response

Eisenach et al. discover A new ion channel of the plant vacuole helps plants react to drought https://doi.org/10.1105/tpc.17.00452 By Cornelia Eisenach Background: Stomata are small pores on plant surfaces that facilitate diffusion of CO2, O2 and water vapor between plant and atmosphere.  During drought, plants need to conserve water to avoid wilting and death. They […]

Photosynthesis in Desert Plants: It’s About Time

Boxall et al. investigate CAM photosynthesis in Kalanchoë fedtschenkoi The Plant Cell (2017). https://doi.org/10.1105/tpc.17.00301 Background: During photosynthesis, most plants use the enzyme Rubisco to capture CO2 during the day. Crassulacean acid metabolism (CAM) plants such as prickly pears, pineapples, and agaves use a more efficient enzyme, phosphoenolpyruvate carboxylase (PEPC), to capture CO2 at night, and […]

Keeping Walls on Track

Schneider et al. explore how secondary cell walls are made. The Plant Cell 2017.  https://doi.org/10.1105/tpc.17.00309 Background: Plant cells are surrounded by robust cell walls that function as dynamic extracellular skeletons and protect plants against their environment. The cell walls make up the bulk of biomass and are utilized in a range of industrial applications, including […]

To Grow or to Defend: That is the Question for Plant Central Metabolism

Fusari et al. perform GWAS to explore primary plant metabolism https://doi.org/10.1105/tpc.17.00232 By Corina M. Fusari and Rik Kooke Background: Primary metabolites such as sugars, organic acids, and amino acids are essential chemical compounds that drive plant growth and development by providing the carbon and energy needed for cell division, expansion, and maintenance and for the […]

How Meiotic Chromosomes Cluster into a “Bouquet”

Zhang et al. explore the behavior of chromosomes during meiosis. The Plant Cell (2017). https://doi.org/10.1105/tpc.17.00287 By Fanfan Zhang Background: In meiosis, plants, animals, and fungi reduce their chromosome numbers by half to form gametes (sperm and eggs) that can fuse to form a cell with a complete set of genetic material. During one stage of meiosis, […]

Space-Time Continuum of Gene Expression in Lateral Root Development

Walker et al. explore how the environment shapes root architecture. The Plant Cell 2017.  https://doi.org/10.1105/tpc.16.00961 By Liam Walker Background: To acquire nutrients and anchor themselves, plant roots spread both vertically and horizontally in soil. Plants typically have a primary root that grows vertically and lateral roots that arise from the primary root and grow horizontally. […]

Flowering Versus Runnering: A Very Important Decision in Strawberry

Tenreira et al. find a gene responsible for the differentiation of the stolon in strawberry. The Plant Cell 2017. https://doi.org/10.1105/tpc.16.00949 Asexual reproduction produces offspring that are genetically identical to the parents. This process takes many forms in flowering plants, including the production of tubers, rhizomes, corms, bulbs, and stolons. In strawberry, stolons , (also known […]

Light Helps Plants Cope with Phosphate Starvation

Liu et al. focus on transcriptional regulation of PHR1 expression. The Plant Cell 2017. https://doi.org/10.1105/tpc.17.00268 Phosphorus (P) is an essential micronutrient for plant growth, development, and metabolism. Phosphate (Pi), the major form of P used by plants, is highly immobile in most soils, making it one of the most limiting nutrients for crop productivity. The overuse […]
