Maize Meristem Matters
Research, The Plant Cell, The Plant Cell: In a NutshellTsuda et al. explore the function of BLH transcription factors in maize meristems
Plants have specialized tissues at the tips of roots and shoots called meristems. Meristem cells are what keep the plant growing; they are undifferentiated cells that continue to divide, providing new cells for growth.…
Special Issue: Plant epigenomics
Plant Science Research WeeklyThe current issue of Genome Biology features a collection of review and research articles on the topic of plant epigenomics, with an overview editorial by Köhler and Springer. This collection "highlights advances in our understanding of the functions of epigenetic modifications, and the application…
Review: Exploiting induced and natural epigenetic variation for crop improvement
Plant Science Research WeeklyVariation provides the raw material for selection and improvement. Springer and Schmitz describe how natural and induced epigenetic variation supplements genetic variation. This review starts with a description of epigenetics, epigenomics (the genome-wide distribution of epigenetic information), and…
Speed breeding: a powerful tool to accelerate crop research and breeding
Plant Science Research WeeklyWatson and Ghosh et al. describe protocols to accelerate the lifecycle of several crop species using "speed breeding", which essentially involves extending the daylength to 22 hours with supplemental lighting. They describe methods and results from glasshouse and growth chamber speed breeding. In spite…
Fatty acids in arbuscular mycorrhizal fungi are synthesized by the host plant ($)
Plant Science Research Weekly, ResearchIn the symbiotic relationship between arbuscular mycorrhizal fungi and plants, the fungal partner greatly enhances the uptake of mineral nutrients (particularly phosphate), while in return it is supplied with organic carbon from the photosynthetic partner. Luginbuehl et al. investigated whether this…
The sequences of 1,504 mutants in the model rice variety Kitaake facilitate rapid functional genomic studies
Plant Science Research Weekly, ResearchLi et al. describe an important new genetic resource, a huge database of Kitaake rice mutants. Kitaake is a short-generation variety of Oryza sativa L. ssp. japonica well suited for genetic studies. The authors sequenced more than 1500 fast-neutron-induced mutants and identified more than 91,000 mutations…
Phenotyping Water Deficit Acclimation Responses
Plant Physiology, Plant Physiology: On The Inside, Research, Research BlogWater deficit (WD) is one of the main environmental stress factors affecting crops and global food security. Acclimation to WD, however, enables plants to maintain growth under unfavorable environmental conditions. To shed light on the molecular mechanisms underlying WD acclimation, Rymaszewski et al.…
ABA is Required for Cuticle Formation Independent of Water Stress
Blog, Plant Physiology, Plant Physiology: On The Inside, ResearchThe waxy cuticle, a key barrier to desiccation and pathogen entry, is a dynamic structure, the composition, area, permeability and thickness of which can change in response to environmental conditions. For example, water deficit in Arabidopsis (Arabidopsis thaliana) triggers an increase in the accumulation…
