Plastid Sulfate Transporters Open Doors To Abiotic Stress Resistance

Climate change is causing more extreme weather patterns and increasing challenges for agriculture. The unusually dry European summer of 2018 caused an 8% drop in cereal production (source: https://ec.europa.eu/info/sites/info/files/food-farming-fisheries/farming/documents/short-term-outlook-autumn-2018_en.pdf).…

A Bridge Between Kingdoms: Introduction of a Golden Gate-based Tool Kit for Cyanobacteria

One goal of synthetic biology is to build artificial pathways for bioengineering of high value compounds. To this end, pathways are not only split into individual reactions, but the expression of one enzyme is also split into individual parts (e.g., promotors, ribosomal binding sites, coding sequences,…

Epigenetic regulation of mRNA polyadenylation site selection

The transcription of many genes is regulated through alternative splicing, with over 60 percent of genes in Arabidopsis thaliana producing more than one mRNA [1]. The most common forms of alternative splicing are intron retention and the use of alternative polyadenylation sites that result in transcripts…

Diverse strategies coping with winter in barley and its relatives

The Poaceae is one of the largest plant families in angiosperms, containing more than 12,000 grass species, which are classified into two major clades: PACMAD (Panicoideae, Arundinoideae, Chloridoideae, Micrairoideae, Aristidoideae and Danthonioideae) and BOP (Bambusoideae, Oryzoideae and Pooideae) (Fig.…

Salicylic acid, senescence, and heterosis

For a number of crops agricultural yields have been boosted by the phenomenon of heterosis or hybrid vigour, where a hybrid outperforms either parent. Understanding the various mechanisms by which heterosis arises may facilitate the breeding of hybrids with increased vigour for further crop varieties…

Roles of the clock in controlling starch metabolism

Author: Masanori Izumi Affiliation: Frontier Research Institute for Interdisciplinary Sciences, Tohoku University, Sendai 980–8578, Japan Plants are photoautotrophs that grow via photosynthetic energy production. Under irradiation, chloroplasts in the plant’s green tissues convert light energy…

Sequencing Plant Transcriptomes at Single-Cell Resolution Allows Unprecedented Characterization of Genetic and Developmental Cellular Processes

Jose M Celedon 1 1 Michael Smith Laboratories, The University of British Columbia, 2185 East Mall, Vancouver, BC V6T 1Z4, Canada. Transcriptomic studies in plants usually involve anonymous survey-style methods, where whole organs or tissues are homogenized, and each cell’s contribution to transcript…

Two pathways for trafficking the borate receptor BOR1

Polar localization of plasma membrane proteins is an important way cells regulate signaling pathways, transport across membranes, and growth. Polarization has obvious cellular effects, but localization of membrane components also contributes significantly to processes such as tip growth in root hairs…

Prohibitin shuttles between mitochondria and the nucleus to control genome stability during the cell cycle

The prohibitin (PHB) protein family is highly conserved from prokaryotes to eukaryotes (Van Aken et al., 2010). Initially identified as a tumor suppressor in rat liver, PHBs in animals are localized in various cell compartments, including mitochondria, nuclei, and plasma membranes, and function as scaffold…
