Abstract

Plastid inheritance in angiosperms is presumed to be largely maternal, with the potential to inherit plastids biparentally estimated for about 20% of species. In , maternal, paternal and biparental inheritance has been reported; however, these studies were limited in the number of crosses and progeny examined. To improve the understanding of plastid transmission in the progeny of 45 interspecific crosses were analyzed in the three subgenera: and Plastid types were assessed following restriction digestion of PCR amplified plastid DNA in hybrid embryos, cotyledons and leaves at different developmental stages. Clade-specific patterns of inheritance were detected such that hybrid progeny from subgenera and predominantly inherited paternal plastids with occasional incidences of maternal inheritance, whereas subgenus showed predominantly maternal and biparental inheritance. Biparental plastid inheritance was also detected in some hybrids from subgenus Heteroplasmy due to biparental inheritance was restricted to hybrid cotyledons and first leaves with a single parental plastid type detectable in mature plants. This indicates that in , plastid retention at later stages of plant development may not reflect the plastid inheritance patterns in embryos. exhibits diverse patterns of plastid inheritance, providing an excellent system to investigate underlying mechanisms in angiosperms.

摘要

被子植物的质体遗传通常被认为是母系遗传,但约有 20%的物种可能存在双亲遗传。在 中,曾报道过母系、父系和双亲遗传;然而,这些研究在交叉和后代的数量上受到限制。为了更好地理解 中的质体传递,对来自 45 个种间杂交的后代进行了分析,这些杂交种来自三个亚属: 和 。在杂种胚胎、子叶和叶片的不同发育阶段,通过聚合酶链反应(PCR)扩增的质体 DNA 的限制性消化来评估质体类型。检测到了具有特定进化枝特征的遗传模式,即来自 和 亚属的杂种后代主要遗传父系质体,偶尔出现母系遗传,而 亚属则主要表现出母系和双亲遗传。在来自 亚属的一些杂种中也检测到了双亲质体遗传,这是由于双亲遗传仅限于杂种子叶和第一片真叶,在成熟植物中可检测到单一亲本质体类型。这表明,在 中,植物发育后期的质体保留可能无法反映胚胎中的质体遗传模式。 表现出多样化的质体遗传模式,为研究被子植物中潜在机制提供了一个极好的系统。
