Vilarrasa-Blasi and coworkers described their impressive work on a huge barcoded Chlamydomonas collection, in which they screened almost 60,000 insertion mutants grown under a wide range of environmental and chemical stress conditions. The authors assessed genotype-phenotype specificity for almost…

Gramene (www.gramene.org) is a curated, open-source, integrated data resource for comparative functional genomics in crops and model plant species. It launched 20 years ago and has continually grown and expanded to incorporate new tools and resources. This update by Tello-Ruiz et al. describes its…

Cis-regulatory elements (CREs) are DNA sequences found near or within genic regions that drive proper gene expression in time and space. Thus, CREs play essential roles in the diversification of spatially distinct cell-types with specialized function in multicellular organisms. To identify CREs underlying…

Producing a genetically-modified or -edited plant requires two distinct processes: DNA modification, followed by regeneration of a plant from the edited cells. The first process has been greatly enhanced by CRISPR/Cas9, but the second has continued to present challenges. Here, Debernardi et al. demonstrate…

CRISPR-Cas is a revolutionary technology that has taken the science of genetic manipulation to higher levels by leaps and bounds. In spite of the ease with which it is used for genome editing, the present delivery methods are not without shortcomings; undesirable effects on non-target regions and…

This week’s announcement of the Nobel Prize in Chemistry being awarded to Emmanuelle Charpentier and Jennifer A. Doudna “for the development of a method for genome editing” comes as no surprise to many. CRISPR (clustered regularly interspaced short palindromic repeats)– Cas (CRISPR-associated…

Proteins’ sub-cellular localizations provide a wealth of information regarding their functional attributes. Protein localization in plant cells is usually done through genetically combining fluorescent proteins to the protein-of-interest. Now, Iwatate and colleagues report the successful localization…

The cell cycle requires a series of transitions from G1 to S, S to G2, G2 to M and M to G1 phases. Determining the cell cycle phase is critical for understanding the molecular events specific to a given stage of cell cycle. However, markers for identifying these cell cycle transitions in plants are not…
