Innovation, conservation, and repurposing of gene function in plant root cell type development (bioRxiv)

Roots have many specialized cells arranged in concentric circles that are functionally homologous among various plant species but with varying cell-type-specific developmental programs. To further understand these developmental programs, Kajala et al. performed TRAPseq (Translating Ribosome Affinity…

Metabolic labeling of RNAs uncovers hidden features and dynamics of the Arabidopsis transcriptome (Plant Cell)

The ability to directly sequence RNAs (RNA-seq) has revolutionized our understanding of gene expression, but it can miss or underestimate short-lived RNAs. Several methods have been developed to identify newly-synthesized mRNAs to provide a snapshot of transcription as it happens. Szabo present Neu-seq,…

An Improved Recombineering Toolset for Plants

Brumos and Zhao et al. developed an improved set of genetic tools to make precise sequence modifications in large DNA fragments and used them to tag hundreds of plant genes, including those involved in auxin production.
