With global temperatures rising, tolerance to heat is becoming increasingly important as a breeding target for crop plants, but it is a highly complex response that includes processes including plant cooling capacity, growth recovery, and maintenance of photosynthesis. Using Arabidopsis, Gao et al. developed…

Drawing on more than 15 years of improvements, Nakano et al. have released public websites and resources for data access, display, and analysis of plant small RNAs, from Arabidopsis to wheat and with many crops and model species represented. The tools can analyze, integrate and display the abundance…

This is a very interesting paper that provide a new, fast and easy protocol, with specific step-by-step instructions, for a trustworthy imaging with cellular resolution of fixed Arabidopsis ovules at different developmental stages. The authors combine two previously outlined techniques: clearing of fixed…

It’s known to all that plant biotechnology can enhance food security, but there are also inevitable disadvantages of these new approaches. At present, introducing DNA into a plant genome is slow and expensive. Recently, Doyle et al. developed a new method which claims to be simple, inexpensive, fast,…

Nothing beats being able see gene expression in real time and space. In recent years, plant biologists have made great strides in understanding plants by using the visual reporters GUS, green fluorescent protein (and other fluorescent proteins) and luciferase. Each of these requires either a substrate…

The ability to introduce base-specific changes through CRISPR/Cas9 gene editing has given scientists fantastic tools with which to understand and modify the genes that control plant development and physiology. New tools and refinements to this toolkit are being developed rapidly. In this new work, Decaestecker…

Multiple approaches like T-DNA insertion and small RNA- and CRISPR-Cas9 mediated gene silencing/knockdown are used to alter the expression of specific genes. This allows researchers to understand gene function during plant development or under any physiological condition. The most challenging task in…

The problem with gene expression profiling is that it preferentially reports on the more highly-expressed genes. Capture sequencing uses targeted sequence libraries to pull out transcripts from genes of interest, including lowly expressed genes, so that their signals aren’t overwhelmed. To explore…
