A team deciphers complicated mechanism underlying genetic diversity.
Movies such as 'X-Men,' 'Fantastic Four,' and 'The Guardians,' which showcase vibrant mutant heroes, have captivated global audiences. Recently, a high-throughput genetic screening of meiotic crossover rate mutants ingarnered the interest of the academic community by unraveling a century-old mystery in the life sciences.
Meiosis and crossover play pivotal roles in biodiversity and have significant implications in breeding where the selection and cultivation of superior traits in crops occur. Typically, most animal and plant species exhibit a minimum of one and a maximum of three crossovers per a pair of homologous chromosomes. The ability to control the number of these crossovers could lead to cultivating crops with specific desired traits.
POSTECH Professor Kyuha Choi stated,"Applying this research to agriculture will enable us to rapidly accumulate beneficial traits, thereby reducing breeding time." He expressed optimism by saying,"We hope this research will contribute to the breeding of new varieties and identification of useful natural variations responsible for desirable traits such as disease and environmental stress resistance, improved productivity, and high-value production.
Scientists have challenged the common assumption that genetic diversity of a species is a key indicator of extinction risk. The scientists demonstrate that there is no simple relationship between ...
