Insights into the genetic bases of differential organ size in cacti flowers: a case study in two contrasting species

This study integrates cellular and molecular data related with the development of differential organ size in Cactaceae. We found that a prolonged period of cell proliferation and expansion in D. speciosus tepals in contrast with D. eichlamii tepals seems to correlate with its final size, while transcriptome analyses point to several DEGs that should be further investigated through gene expression analyses as well as other reverse genetics approaches.
