突变体fon7，37%的小穗表现出花器官数量增加，尤其是雄蕊和雌蕊。组织学分析显示子房的数量取决于柱头数量：两个或三个柱头的小穗仅包含一个子房，而四个柱头的小穗有两个子房。

2023年1月5日 · A single nucleotide polymorphism (G to A) was discovered at the intron splicing donor site of FON7, which caused the skipping of the entire sixth exon in the mutant, resulting in the deletion of 144 bp. Furthermore, the T-DNA-tagged line displayed the same floral organ number phenotype as the fon7 mutant.

snp指数的计算证实os08g0299000是调控花器官数量的候选基因，命名为floral organ number7（fon7）。 在 FON7 的内含子剪接供体位点发现单核苷酸多态性（G 到 A），导致突变体中整个第六外显子的跳跃，导致 144 bp 的缺失。

Furthermore, the T-DNA-tagged line displayed the same floral organ number phenotype as the fon7 mutant ...

Sequence comparison revealed that full-length FON7 cDNA contains eight exons in the wild-type but lacks the entire exon 6 in the mutant (Fig 4 c). Consequently, the FON7 protein is predicted to...

2023年1月5日 · Genetic and MutMap analyses revealed that floral organ number is controlled by a single recessive gene located between the 8.0 and 20.0 Mb region on chromosome 8 and a single nucleotide polymorphism was discovered at the intron splicing donor site of FON7, which caused the skipping of the entire sixth exon in the mutant.

FON7 (Os08g0299000) encodes a member of the mediator of ErbB2-driven cell motility protein (MEMO1) family. A total of 62 genes in 47 organisms, including human, animals, and plants, were found to encode MEMO1 proteins, 80% of which occurred in plant species.
