The Plant Cell Is Accepting Applications for Assistant Features Editors

The Plant Cell has several openings for new Assistant Features Editors (AFEs) in 2020. AFEs provide a valuable service to the journal, our authors, and the scientific community. In return, AFEs receive experience in writing and communicating scientific findings to a wide audience, as well as networking and learning about the workings of The Plant […]

Exploring Pollen Patterns to Learn How Cells Create Distinct Domains

Lee et al. identify a protein involved in pollen aperture development and the formation of distinct membrane domains in microspores. https://doi.org/10.1105/tpc.18.00442  By Byung Ha Lee and Anna Dobritsa Background: Pollen grains are famous for their ability to develop various intricate patterns on their surfaces. One type of patterns common to the pollen grains of most plant […]

SUMO Aids Rapid Regulation of Hormone Responses

Srivastava et al. identify a mechanism for rapid regulation of jasmonic acid signaling. Plant Cell  https://doi.org/10.1105/tpc.18.00036 Background: The sessile nature of plants dictates that growth must be integrated with changes in the natural environment. Modulation of hormone signalling pathways plays a key role in this process. Jasmonic acid (JA) regulates a wide spectrum of plant […]

Chloroplasts can Import Folded Proteins

Ganesan et al. investigate protein import into chloroplasts The Plant Cell (2018).  By Iniyan Ganesan and Steven Theg Background: Chloroplasts are the green compartment in plant cells that carry out photosynthesis. Most plant proteins are made in the cytoplasm and many need to cross different cell membranes to reach their final cellular destination. Chloroplasts are […]

Programmed Cell Death in the Root Cap

Huysmans et al. identify cell death regulatory proteins in root cap cells. Plant Cell https://doi.org/10.1105/tpc.18.00293 Background: Some plants, such as giant sequoia trees, can grow into the “Largest Living Things on Earth.” Ironically, most of a tree’s biomass is actually not alive but is formed by persistent cell corpses called wood. Wood formation ends in […]

PGI1 is a Determinant of Seed Yield

Bahaji et al. identify an important player determining seed yield in Arabidopsis. https://doi.org/10.1105/tpc.18.00312 Background: Oilseeds are major sources of calories for human consumption and have a significant agricultural and industrial value. Seed number and weight are the two main components of seed yield. In plants, plastidial isoprenoid derived hormones (e.g. cytokinins [CKs] and gibberellins [GAs]) […]

Nectary Development in Petunia and Arabidopsis, a Sweet Story!

Morel et al. study the nectar-producing organs in flowers and identify major regulators of nectary size https://doi.org/10.1105/tpc.18.00425 By Patrice Morel and Michiel Vandenbussche Background: Nectaries are the organs that produce nectar, a sugary substance that motivates pollinators such as insects to visit flowers and subsequently pollinate them, thus ensuring the plant’s reproductive success. During evolution, […]
