That orange seed you just spit out? Grow a tree 2020-02-25T05:00:00Z Today, apomictic reproduction has been confirmed in more than 400 plant species but no staple crops. ‘Game changer.’ Scientists are genetically engineering crops to clone themselves 2023-05-17T04:00:00Z Anna Koltunow of the University of Queensland is developing apomictic varieties of sorghum and cowpea, important crops for farmers in sub-Saharan Africa. ‘Game changer.’ Scientists are genetically engineering crops to clone themselves 2023-05-17T04:00:00Z Like most plants, the apomictic rice now under development still needs pollen to fertilize its endosperm—the seed tissue that provides sustenance for the developing embryo. ‘Game changer.’ Scientists are genetically engineering crops to clone themselves 2023-05-17T04:00:00Z There’s a palpable “sense of excitement” in the field, says Mary Gehring, a molecular biologist at the Whitehead Institute and the Massachusetts Institute of Technology who studies development in apomictic plants. ‘Game changer.’ Scientists are genetically engineering crops to clone themselves 2023-05-17T04:00:00Z Many naturally apomictic plants instead create gametes through mitosis, with no change in the chromosome count. ‘Game changer.’ Scientists are genetically engineering crops to clone themselves 2023-05-17T04:00:00Z Gehring’s team recently received funding to try to engineer plants that develop endosperm without being fertilized, a feat that some naturally apomictic plants are capable of. ‘Game changer.’ Scientists are genetically engineering crops to clone themselves 2023-05-17T04:00:00Z If the team is successful, future apomictic crop varieties wouldn’t rely on pollen at all—enabling them to produce bountiful seeds even during heat waves. ‘Game changer.’ Scientists are genetically engineering crops to clone themselves 2023-05-17T04:00:00Z Famoso notes that some countries, especially in Asia, that have resisted genetically modified foods may not want to import apomictic rice. ‘Game changer.’ Scientists are genetically engineering crops to clone themselves 2023-05-17T04:00:00Z |
