Abstract

In the framework of a gene flow assessment, we investigated the natural hybridization rate between (AADD genome) and (AA genome). The latter species, a diploid progenitor of , is spontaneously present in South Africa. Reciprocal crosses were performed without emasculation between and Neither examination of the morphological characteristics nor flow cytometry analysis of the 335 plants resulting from the × cross showed any hybrid features. Of the 148 plants produced from the × cross, three showed a hybrid phenotype, and their hybrid status was confirmed by SSR markers. Analysis of DNA content by flow cytometry and morphological traits clearly showed that two of these plants were triploid (AAD). The third plant had a flow cytometry DNA content slightly higher than In addition, its morphological characteristics (plant architecture, presence and size of petal spots, leaf shape) led us to conclude that this plant was AAAD thus resulting from fertilization with an unreduced AA gamete of the female parent. Fluorescent Hybridization (FISH) and meiotic behavior confirmed this hypothesis. To the best of our knowledge, this is the first description of such gametes in , and it opens new avenues in breeding programs. Furthermore, this plant material could provide a useful tool for studying the expression of genes duplicated in the A and D cotton genome.

摘要

在基因流评估的框架内，我们调查了 （AADD 基因组）和 （AA 基因组）之间的自然杂交率。后者是 的二倍体祖先，在南非自然存在。在 和 之间进行了无需去雄的回交。来自 × 杂交的 335 株植物的形态特征检查和流式细胞术分析均未显示任何杂种特征。来自 × 杂交的 148 株植物中，有三株表现出杂种表型，其杂种状态通过 SSR 标记得到证实。通过流式细胞术分析 DNA 含量和形态特征清楚地表明，其中两株是三倍体（AAD）。第三株植物的流式细胞术 DNA 含量略高于 。此外，其形态特征（植株结构、花瓣斑点的存在和大小、叶片形状）使我们得出结论，该植物是 AAAD，因此是由母本 的未减数 AA 配子受精产生的。荧光杂交（FISH）和减数分裂行为证实了这一假设。据我们所知，这是首次在 中描述此类配子，为育种计划开辟了新途径。此外，这种植物材料可为研究在 A 和 D 棉花基因组中重复的基因表达提供有用的工具。
