Chromosomal and Genetic Variations

Chromosomal and Genetic Variations is a research topic within Plant Science. Science Explorer counts 41k research works in it since 1950. 9.9% of them reached the world's top 10% most cited for their field and year.

This cluster of papers explores the evolution of plant genomes, with a focus on polyploidy, transposable elements, small RNAs, and the role of repetitive elements. It investigates the impact of genome duplication on genetic diversity, speciation, and epigenetic regulation, shedding light on the evolutionary significance of these processes in plants.
