Web(Inducer lines), is unique to maize (Hu et al, 2016; Kelliher et al, 2024). There are two approaches for in vivo haploid induction in maize resulting in paternal or maternal haploids respectively (Rober et al, 2005; Zhang et al, 2008). In maternal haploids, the genomes originate exclusively from the seed parent plant. Haploid induction WebFeb 23, 2024 · Since the number of haploids cannot be explained just by semigamous zygotes, and based on the detection of aneuploidies in selfed ecs1 ecs2 double mutants, the authors suggest chromosome elimination as an additional source mechanism (Figure 1B), but further research will be needed to clarify the haploid production mechanisms.
