Phytophthora infestans: The notorious plant destroyer is a master manipulator

FEATURED FIGURE CAPTION:  Live imaging of Phytophthora infestans (magenta) growing on Nicotiana benthamiana cells (cyan). Cells that are colonized by the pathogen show increased numbers of vesicles (bright cyan dots) compared to cells that haven’t been colonized yet. Petre, Contreras, et al. investigate how the microbe responsible for the Irish potato famine manipulates plant cell […]

Exploring the evolution of immunity responses in Brassicaceae

Winkelmüller, Entila, Anver et al. uncover the considerable variation in gene expression patterns in closely related Brassicaceae species during pattern triggered immunity. Plant Cell  By Thomas M. Winkelmüller, Frederickson D. Entila, Shajahan Anver, and Kenichi Tsuda  Background: Plants are surrounded by many microorganisms. To react to these microbes, plants have evolved receptors to sense conserved […]

Radical Information – Daily Stress and When the Light is Just Too Strong…

Haber et al. developed an automated microplate system to continuously monitor levels of reactive oxygen species in planta. Plant Cell. https://doi.org/10.1093/plcell/koab068. By Zechariah Haber and Shilo Rosenwasser, The Robert H. Smith Institute of Plant Sciences and Genetics in Agriculture, The Hebrew University of Jerusalem Background: As sessile organisms, plants must continually sense and adapt to […]

A multiply-interlocked regulatory loop in seasonal leaf senescence

Wang et al. identify autumn senescence-associated genes and transcription factors in Populus and demonstrate a regulatory role for alternative splicing. The Plant Cell. (2021) https://doi.org/10.1093/plcell/koab046 By Hou-Ling Wang, Yi Zhang, Hongwei Guo and Zhonghai Li, Beijing Forestry University and Southern University of Science and Technology Background: Leaf senescence is one of the most common developmental […]

Look at those red, ripe, and yummy strawberries; Thanks FaRIF!

By Carmen Martín-Pizarro and David Posé, Instituto de Hortofruticultura Subtropical y Mediterránea (IHSM), Universidad de Málaga-Consejo Superior de Investigaciones Científicas. Background: Strawberry (Fragaria ´ ananassa) is one of the most important fruit crops worldwide, with a unique flavor and aroma and a high nutritional value that are acquired as the fruits ripen. During ripening, fruits […]

Membrane Insertion of Plastidic β-barrel Proteins

Gross et al. describe how plastidic β-barrel proteins are inserted into the outer envelopes of plastids. The Plant Cell (2021) https://doi.org/10.1093/plcell/koab052 By Nicole Spies, Lucia Gross, and Enrico Schleiff Background: Due to their endosymbiotic origin, chloroplasts possess both an outer and inner envelope membrane. 95% of all chloroplasts proteins are translated in the cytosol and […]

Translational Recoding Corrects Frameshift Mutations in Chloroplasts

Malinova et al. provide genetic and biochemical evidence for ribosomal frameshifting in chloroplasts. Plant Cell https://doi.org/10.1093/plcell/koab050 By Irina Malinova and Stephan Greiner Background: Translational recoding or ribosomal frameshifting – a process when ribosomes either omit nucleotide(s) or move back along the mRNA template during protein synthesis – is typical for the bacteria. Chloroplasts (photosynthetic plant […]

A Rosy Scenario for Flower Opening

Cheng et al. explore how ethylene promotes the asymmetric growth of petal bases to promote flower opening in rose. The Plant Cell (2021) https://doi.org/10.1093/plcell/koab031  By Chengchen Xia, Junping Gao, and Nan Ma  Background: Flowers are unique structures in angiosperms that are used for reproduction. Proper flower opening is crucial for attracting pollinators and is pivotal […]

Genomes losing balance – what is the consequence?

Shi et al. (2021). Plant Cell. Gene expression in diploid aneuploids and polyploids. Plant Cell. https://doi.org/10.1093/plcell/koab030 By Xiaowen Shi and James A. Birchler Division of Biological Sciences, University of Missouri, Columbia, MO 65211 Background: A change in the number of chromosomes can cause problems with growth, development, and function in an organism. One famous example […]
