A selfish genetic element confers non-Mendelian inheritance in rice

Abstract: Selfish genetic elements are pervasive in eukaryote genomes, but their role remains controversial. We show that , a major quantitative genetic locus for hybrid male sterility between wild rice () and Asian cultivated rice (), contains two tightly linked genes [ () and ]. encodes a toxic genetic element that aborts pollen in a sporophytic manner, whereas encodes an antidote that protects pollen in a gametophytic manner. Pollens lacking are selectively eliminated, leading to segregation distortion in the progeny… Show more

“…To observe the subcellular localisation of OsPEX5 and OsOPR7, the coding region sequences of OsPEX5 and OsOPR7 were fused to the N‐terminus or C‐terminus of green fluorescent protein (GFP) in the pAN580–GFP vector (Yu et al ., ), respectively. The coding region sequences of OsPEX5 was also inserted into the N‐terminal of mCherry.…”

“…Our current work shows that many of these predicted drive genes are able to drive in the right genetic context. This work expands the rapidly growing number of bona fide drive genes identified in recent years [4,[16][17][18][33][34][35][36][37][38][39][40][41][42][43].…”

“…A growing body of evidence indicates that meiotic drive is pervasive in eukaryotes, and more drivers are identified each year. This includes the gamete-killing type of meiotic drivers described in this work (Bauer et al, 2012; Bravo Núñez et al, 2018; Bravo Núñez et al, 2020; Burt and Trivers 2006; Didion et al, 2015; Grognet et al, 2014; Hammond et al, 2012; Hu et al, 2017; Larracuente and Presgraves 2012; Long et al, 2008; Nuckolls et al, 2017; Pieper et al, 2018; Rhoades et al, 2019; Vogan et al, 2019; Xie et al, 2019; Yang et al, 2012; Yu et al, 2018), but also extends to other drivers that use completely different methods to gain a transmission advantage. For example, biased gene conversion favoring unbroken DNA during meiotic recombination is a form of meiotic drive tied to the mechanisms of double-strand break repair (Marais 2003).…”
