“…Considering that MTL and PLD3 encode phospholipases, and that lipid treatments have been shown to produce HI (C. Jiang et al ., 2022), we could hypothesize putative roles for lipid homeostasis in MTL/PLD3 HI systems (Fig. 3b; Jacquier & Widiez, 2021).…”

SummaryIn planta haploid induction (HI), which reduces the chromosome number in the progeny after fertilization, has garnered increasing attention for its significant potential in crop breeding and genetic research. Despite the identification of several natural and synthetic HI systems in different plant species, the molecular and cellular mechanisms underlying these HI systems remain largely unknown. This review synthesizes the current understanding of HI systems in plants (with a focus on genes and molecular mechanisms involved), including the molecular and cellular interactions which orchestrate the HI process. As most HI systems can function across taxonomic boundaries, we particularly discuss the evidence for conserved mechanisms underlying the process. These include mechanisms involved in preserving chromosomal integrity, centromere function, gamete communication and/or fusion, and maintenance of karyogamy. While significant discoveries and advances on haploid inducer systems have arisen over the past decades, we underscore gaps in understanding and deliberate on directions for further research for a more comprehensive understanding of in vivo HI processes in plants.

“…Research on the maize in planta haploid induction system allowed the identification of 3 main molecular players: NOT-LIKE-DAD/MATRILINEAL/ZmPHOSPHOLIPASE-A1 ( NLD/MTL/ZmPLA1 ) ( Gilles, Khaled, et al 2017 ; Kelliher et al 2017 ; Liu et al 2017 ), DOMAIN OF UNKNOWN FUNCTION 679 MEMBRANE PROTEIN ( ZmDMP ) ( Zhong et al 2019 ), and PHOSPHOLIPASE D3 ( ZmPLD3 ) ( Li et al 2021 ). Although the mode of action of maize haploid induction remains elusive, both NLD/MTL/ZmPLA1 and ZmPLD3 relate to lipid homeostasis ( Gilles et al 2021 ; Jacquier and Widiez 2021 ), whereas ZmDMP pinpoints links between haploid induction and fertilization defects ( Jacquier et al 2020 , 2021 ). More precisely in Arabidopsis , the double mutant Atdmp8/9 induces haploid embryos ( Zhong et al 2020 ) and shows fertilization defects with preferential single fertilization of the central cell ( Takahashi et al 2018 ; Cyprys et al 2019 ).…”
