Dual role of the histone variant H2A.Z in regulation of stress-response genes

/
Histones are protein complexes around which genomic DNA is wrapped; post-translational modifications to histone proteins and alterations of histone protein composition affect transcription. H2A.Z is a widely conserved variant form of histone H2A that has been implicated in various forms of transcriptional…

Spotlight: The fate of the world’s plants

/
In 2016, Kew Gardens released a report “The State of the World’s Plants”, which includes estimates of the total number of plant species on Earth and the percentage of those facing extinction.  Pimm and Raven delve into those numbers and offer the opinion that many species will be lost before they…

Method: Microphenotron, a miniaturized robotic phenotyping platform

/
High-throughput screening greatly extends the number of individuals that can be screened, so is particularly crucial for genetic or chemical genetic approaches.  Burrell et al. report on a miniaturized robotic phenotyping platform, “Microphenotron” designed for chemical genetic screening. Seeds…

Review: Using mustard genomes to explore the genetic basis of evolutionary change ($)

/
Brassicaceae is one of the largest angiosperm families and provides many opportunities for studies of evolution. Of course, its most famous species, Arabidopsis thaliana is an important resource, but Brassicaceae also includes the very interesting Brassica crops (cabbage, turnip) that demonstrate the…

Review: Plant sex determination

/
Most angiosperms are hermaphrodites and produce flowers that have both male (stamens / sperm) and female (carpels / egg) parts. Pannell reviews the developmental and genetic programs that lead to these “perfect” flowers, as well as those that underlie reproductive structure development in dioecious…

Review: Progeny responses to maternal vs progeny environmental cues

/
The range of responses an individual could display is a contribution of the inheritance of gene variants that determine such responses and the environments experienced by the individual itself and prior generations (nongenetic inheritance). In this review, we discuss recent empirical data to help us…

Review: Methods of cell-specific hormone analysis ($)

/
Plant hormones are active at very small quantities and often act differently in different cell types. Various methods, primarily involving mass spectrometry and sensors, have been developed to identify and quantify hormones with cellular-level precision. Novák et al. review these methods and discuss…
