Agronomic traits

  • American scientists describe a new approach to using CRISPR to improve biological nitrogen fixation (BNF) and yield in rice. The authors used gene editing to target the breakdown of apigenin, a flavone that induces BNF. Gene-edited rice showed increased apigenin root exudation and biofilm formation. This favoured the enrichment of diazotrophic bacteria recruitment. In addition, modified rice plants displayed increased grain yield when grown at limiting soil nitrogen conditions.

Reviews

  • A review in Plant Communications discusses CRISPR solutions to control crop drought and salinity stress. First, it updates plant responses to these abiotic stresses at the morphological, physiological, and molecular levels. Next, it highlights recent advances in CRISPR-based tools and their use to understand the multi-level nature of plant adaptations to drought and salinity stress. Finally, the authors suggest how the integration of CRISPR tools with modern breeding approaches can be used to engineer resistance.
  • Another review by scientists in South Africa discusses CRISPR-Cas-based tools for the targeted control of plant viruses. The study outlines strategies for delivering CRISPR-Cas reagents to plant cells and provides an overview of recent advances in engineered CRISPR-based resistance against DNA and RNA viruses in plants. Finally, the authors provide insight into the limitations and challenges that CRISPR-Cas technology currently faces.
  • "Genome Editing Technologies for Crop Improvement" is the title of a new book, edited by Kaijun Zhao, Rukmini Mishra, and Raj Kumar Joshi and published by Springer. In 19 chapters, the book discusses general information on the recently emerged new biotechnology of genome editing, practical methods for constructing primary vectors for plant genome editing, and the current application of genome editing tools in the genetic improvement of different crops.
