“…ZmPLA1/MATL/NLD genes have only been identified in monocots (Kelliher et al, 2017; Yao et al, 2018; Liu et al, 2019), while genes related to a second maize maternal haploid inducer gene, Zea may DOMAIN OF UNKNOWN FUNCTION 679 membrane protein ( ZmDMP ), have been identified in both monocots and dicots (Zhong et al, 2020). The utility of dmp pollen for HI was recently demonstrated in the model dicot plant Arabidopsis thaliana (Zhong et al, 2020) and two dicots crops Medicago truncatula (Wang et al, 2021b) and Solanum lycopersicon (tomato) (Zhong et al, 2021), but it is not known whether this approach can be translated to other dicot crops. Here, we developed a method to identify candidate DMP genes for HI in dicot crops and demonstrated DMP ‐mediated maternal HI in two easily transformed allotetraploid crops from different plant families that are also easy to hybridize, B. napus and N. tabacum .…”
