Recent advances in crop transformation technologies | Nature Plants

Agriculture is experiencing a technological inflection point in its history, while also facing unprecedented challenges posed by human population growth and global climate changes. Key advancements in precise genome editing and new methods for rapid generation of bioengineered crops promise to both revolutionize the speed and breadth of breeding programmes and increase our ability to feed and sustain human population growth. Although genome editing enables targeted and specific modifications of DNA sequences, several existing barriers prevent the widespread adoption of editing technologies for basic and applied research in established and emerging crop species. Inefficient methods for the transformation and regeneration of recalcitrant species and the genotype dependency of the transformation process remain major hurdles. These limitations are frequent in monocotyledonous crops, which alone provide most of the calories consumed by human populations. Somatic embryogenesis and de novo induction of meristems — pluripotent groups of stem cells responsible for plant developmental plasticity — are essential strategies to quickly generate transformed plants. Here we review recent discoveries that are rapidly advancing nuclear transformation technologies and promise to overcome the obstacles that have so far impeded the widespread adoption of genome editing in crop species. This Perspective reviews recent advances in crop transformation technologies that promise to lead to the widespread adoption of genome editing in crop species.

7 ways CRISPR gene editing could transform food – Genetic Literacy Project

Here are some of the ways scientists are using CRISPR to create healthier, more appealing, and more resilient foods — putting us closer to a future in which every person not only has access to the healthy foods they need, but actually wants to eat those foods, too.

CRISPR-pedia: Everything you need to know about gene-editing our way to a lower-carbon, more productive farming future – Genetic Literacy Project

The world population is growing. At the same time, climate change is making it more difficult to grow many important food crops. So, researchers and farmers need to figure out how to adapt agriculture to changing, and sometimes increasingly harsh environmental conditions.

CRISPR is revolutionizing agriculture but modifying fruit remains challenging. Here’s how scientists are working to overcome that barrier – Genetic Literacy Project

One of the major advantages of CRISPR-CAS-edited crops over the classic genetically modified (GM) crops is that the former does not contain any foreign DNA, making them indistinguishable from those developed by conventional plant breeding.

CRISPR is 10: A decade of gene editing refinements presents new ways to address ‘ agricultural diseases thought to be incurable – Genetic Literacy Project

Because CRISPR applications promise so many benefits, we are impatient to see them realized. Indeed, we may complain that the development of CRISPR therapies is too slow.

Prospective UK precision breeding bill could unshackle gene editing from outdated GMO regulations – Genetic Literacy Project

“There is a huge body of scientific evidence that modern genetic manipulation tools, whether that’s CRISPR-Cas9 gene editing or other methodologies, are frankly safer than the methodologies that have historically been used for the last hundred years,” said Neil Ward

CRISPR gene-edited rice could help soil bacteria produce nitrogen fertilizer. Here’s how it works – Genetic Literacy Project

Researchers have used CRISPR to engineer rice that encourages soil bacteria to fix nitrogen, which is required for their growth. The findings may reduce the amount of nitrogen fertilizers needed to grow cereal crops, save farmers in the United States billions of dollars annually, and benefit the environment by reducing nitrogen pollution.

Orange and grapefruit growers devastated by citrus diseases have new hope: CRISPR gene editing – Genetic Literacy Project

In the past few decades, two bacterial diseases — Huanglongbing (HLB) and citrus canker— have decimated the Florida citrus industry by killing millions of trees, costing the state billions in lost revenue, and reducing production by 80%.
