Update: Stomatal biology of CAM plants
Plant Physiology: Updates, Plant Science Research Weekly, Research Blog0 Comments
/
Crassulacean acid metabolism (CAM) plants open their stomata at night, decreasing water loss and increasing water-use efficiency as well as drought tolerance. Males and Griffiths review the stomatal biology of CAM plants as compared to C3 plants. For example, CAM stomata are relatively insensitive to…
1135 Arabidopsis genomes reveal global pattern of polymorphism
Plant Science Research Weekly, ResearchThere are many accessions of Arabidopsis thaliana beyond the ecotypes predominantly used in research laboratories. In this article, The 1001 Genomes Consortium describe a resource based on whole-genome sequencing of 1,135 A. thaliana genomes from Europe, North Africa, and North America. This data…
Allelic diversity underlying flowering-time adaptation in maize landraces ($)
Plant Science Research Weekly, ResearchLandraces are native varieties that have been selected for adaptation to their native environment, and as such they provide a wealth of largely unexplored genetic potential. Romero Navarro et al. used a new approach called F-one association mapping (FOAM) in combination with genome-wide association strategy…
Review: Winter and summer dormancy: similar adaptive strategies?
Plant Science Research Weekly, ResearchDormancy (growth arrest) is a state by which seeds and plants can survive harsh conditions. Seasonal dormancy is a strategy to survive seasonally unfavorable conditions. Plants can display winter and summer dormancy. Although woody species are the main study systems for winter dormancy, herbaceous species…
Review: Mycorrhizal ecology and evolution: the past, present and the future
Plant Science Research Weekly, ResearchThere are about 50,000 fungal species that form mycorrhizal associations with about 250,000 plant species. These associations significantly increase plant productivity by increasing nutrient uptake, particularly nitrogen and phosphorus, although with a considerable carbon cost to plants. Van der Heijden…
Review: Isoprene research – 60 years later, the biology is still enigmatic ($)
Plant Science Research Weekly, ResearchSixty years ago, the first report of isoprene (C5H8; 2-methyl-1,3-butadiene) emissions from plants was published. Isoprenes are the largest source of non-methane hydrocarbons in Earth’s atmosphere; furthermore, isoprene is reactive in atmospheric chemistry and can be converted into a variety of harmful…
Contrasting phytochrome responses in wild plants
Plant Science Research Weekly, ResearchShade avoidance syndrome (SAS) is a growth pattern in which stem and petiole elongation is stimulated in plants exposed to vegetative shade, as revealed through a low ratio of red to far-red light perceived by phytochrome; red light is absorbed by chlorophyll, leading to a far-red enrichment in light…
Review: Seed Coating: Science or Marketing Spin? ($)
Plant Science Research Weekly, ResearchTo meet the Sustainable Development Goal 2, Zero hunger, degraded ecosystems should be brought under cultivation with quality seeds that have good germination and produce healthy seedling for vigorous plant population establishment. Seed technologies like seed coating with inoculants, germination promoters,…
Response of US crops to elevated temperatures
Plant Science Research Weekly, ResearchClimate change could affect agricultural productivity by increasing the number of days with temperatures above 30°C that staple crops like soybean, maize and wheat will experience during a given growing season. Schauberger et al. used nine statistical models to assess future threats to US crops. They…
