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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
Yang et al. use haploid induction, genomic and transcriptomic sequencing to explore gene expression changes across the genome when the chromosome arm was varied in haploid maize. By Hua Yang, James Birchler, University of Missouri-Columbia Background: The phenotypic consequences of the addition or subtraction of part of a chromosome is more severe than changing the […]
