Original story from Texas Tech University (TX, USA).<\/a><\/p>\n

A research team has created gene-edited crops without using tissue culture. <\/strong><\/p>\n

A team of plant biotechnologists led by\u00a0Gunvant Patil<\/a>\u00a0at\u00a0Texas Tech University<\/a>\u00a0(TX, USA) has developed a groundbreaking method that could dramatically speed up the development of gene-edited crops. The method would allow scientists to bypass one of the most time-consuming and technically challenging steps in plant biotechnology \u2013 tissue culture.<\/p>\n

The study introduced a synthetic regeneration system that enables plants to grow new shoots directly from wounded tissue, eliminating the need for traditional lab-based regeneration steps that often take months and limit which crops can be bioengineered. This work was primarily carried out by graduate student\u00a0Arjun Ojha Kshetry<\/a>\u00a0in Texas Tech\u2019s\u00a0Institute of Genomics for Crop Abiotic Stress Tolerance<\/a>\u00a0(IGCAST).<\/p>\n

\u201cPlant regeneration has always been the bottleneck in biotechnology,\u201d shared Patil, senior author and associate professor in the IGCAST. \u201cOur approach unlocks the plant\u2019s own natural ability to regrow after injury, allowing us to directly induce new, gene-edited shoots without spending months in tissue culture. This could fundamentally change how we develop improved crops.\u201d<\/p>\n

In most genetic engineering methods, researchers must regenerate a whole plant from a single cell using precise nutrient and hormone combinations, a slow, expensive and often genotype-dependent process. Patil\u2019s team instead engineered a simple system that reactivates the plant\u2019s own wound-healing and regeneration pathways.<\/p>\n

\"BioTechniquesTaking root: the techniques growing genetically engineered plants<\/strong><\/a><\/p>\n

Genetically engineered plants aren\u2019t new, but the techniques being used to edit their genomes are becoming increasingly refined.<\/p>\n

By combining two powerful genes \u2013 WIND1, which triggers cells near a wound to reprogram themselves, and the isopentenyl transferase (IPT) gene, which produces natural plant hormones promoting new shoot growth \u2013 the team created a self-contained regeneration cascade. This system successfully generated gene-edited shoots in multiple crops, including tobacco, tomatoes and soybeans.<\/p>\n

\u201cThis system works like turning on a hidden switch in the plant,\u201d Patil explained. \u201cWhen we activate the wound-response genes, the plant essentially starts rebuilding itself, this time carrying the desired genetic changes.\u201d<\/p>\n

The new technique also integrates with CRISPR-based genome-editing tools, enabling precise gene modifications in a single step. The ability to generate transgenic, or gene-edited, plants directly on the parent plant could make crop improvement faster, cheaper and accessible to a wider range of species.<\/p>\n

\u201cThis is a significant step toward democratizing plant biotechnology,\u201d commented\u00a0Luis Herrera-Estrella<\/a>, a co-author, director of IGCAST and the President\u2019s Distinguished Professor of Plant Genomics at Texas Tech. \u201cBy reducing dependence on tissue culture and specialized lab facilities, this system could make genetic innovation possible for many more crops and research programs worldwide.\u201d<\/p>\n

The study demonstrated higher regeneration success rates in tobacco and tomatoes using the new system, outperforming many existing tissue culture-free transformation methods. Even in soybeans, a notoriously difficult species for genetic modification, the researchers achieved gene-editing with minimal reliance on conventional tissue culture.<\/p>\n

\u201cThe development of a tissue-culture-free transformation system represents a major leap forward for agricultural research,\u201d shared\u00a0Clint Krehbiel<\/a>, dean of the\u00a0Davis College of Agricultural Sciences & Natural Resources<\/a> at Texas Tech. \u201cThis breakthrough not only accelerates crop improvement but also demonstrates how our faculty and students are addressing some of the most pressing challenges in global food security and sustainable production.\u201d<\/p>\n

The research marks a major milestone in plant synthetic biology. Future work will focus on adapting this approach to other major food and energy crops, including cereals and legumes, and integrating it with precision genome editing technologies to accelerate breeding for global food security.<\/p>\n

\u201cOur ultimate goal is to develop a universal platform for plant transformation, one that cuts the time from discovery to improved crop variety by half or more,\u201d Patil concluded. \u201cThis has implications not only for research, but also for tackling real-world challenges like environmental resilience, disease resistance and improved nutrient use efficiency.\u201d<\/p>\n
