In planta haploid embryo induction is a powerful plant breeding tool, but is limited to very few crops. Two recent studies by Wang et al. and Lv et al. report seed-based haploid systems that produce paternal haploid embryos by engineering CENTROMERIC HISTONE H3 (CENH3). Together with recent translation of maize maternal haploid induction ability into wheat and rice, this extends our collection of haploid inducer lines.
在植物中，单倍体胚胎诱导是一种强大的植物育种工具，但仅限于极少数作物。王等人和吕等人最近的两项研究报告了基于种子的单倍体系统，该系统通过对着丝粒组蛋白H3（CENH3）进行工程改造来产生父本单倍体胚胎。再加上最近将玉米母本单倍体诱导能力转移到小麦和水稻中，这扩展了我们的单倍体诱导系库。
