Divergent outcomes of genetic conflict on the UV sex chromosomes of Marchantia polymorpha and Ceratodon purpureus.

This study compares two plant species, Marchantia polymorpha and Ceratodon purpureus, and their genetic mechanisms for sexual dimorphism. The findings suggest that different species exhibit distinct ways of controlling sexual development, which emphasizes the need for further research in understanding the evolution of sexual dimorphism.

Genome-wide association study to identify novel loci and genes for Fusarium root rot resistance in sweet potato using genotyping-by-sequencing.

Scientists identified two SNP markers (LG3_22903756 and LG4_2449919) associated with Fusarium root rot resistance in sweet potatoes. These markers can be used to develop molecular markers for selecting resistant varieties and aid in functional analysis of candidate genes.
