Absent daddy, but important father

TL;DR

This paper discusses the process of haploid embryo induction in plants, highlighting recent discoveries about maternal genome dominance and the role of haploid inducer lines in seed formation.

Contribution

It introduces new insights into the mechanisms of haploid embryo induction, expanding understanding of plant reproductive biology.

Findings

Haploid inducer lines can produce seeds with only maternal genomes.

Recent studies reveal new mechanisms behind haploid embryo formation.

Maternal genome dominance plays a key role in this process.

Abstract

Mixing maternal and paternal genomes is the base of plant sexual reproduction, but some so-called 'haploid inducer lines' lead to the formation of seeds bearing well-developed embryos with solely the maternal genome. A recent study adds a new piece to the puzzle of this enigmatic in planta haploid embryo induction process.
