octoploid，英语单词，译为“八倍体”，译为“八倍体（的）”。 In this paper, the reciprocal cross was made between octoploid triticale and common wheat. 本文用八倍体小黑麦与普通小麦进行正反交。 We introduced the genome of Thinopyrum into common wheat, and formed the new intermediate type of octoploid Trititrigia. 在普通小麦的遗传背景下导入了偃麦草的染色体组而形成的新的中间类型八倍体小偃麦。
2024年9月12日 · 41 current phylogenetic evidence supports a single origin of wild octoploid species 7. The octoploid 42 strawberry genome has four subgenomes, A, B, C, and D, which originated from four different 43 diploid species. There is scientific consensus that F. vesca subsp. bracteata (renamed here F.
Origin and evolution of the octoploid strawberry genome
Cultivated strawberry emerged from the hybridization of two wild octoploid species, both descendants from the merger of four diploid progenitor species into a single nucleus more than 1 million years ago. Here we report a near-complete chromosome-scale assembly for cultivated octoploid strawberry (F …
Haplotype-resolved genomes of wild octoploid progenitors …
2023年8月3日 · Here we report haplotype-resolved genomes of two wild octoploids (Fragaria chiloensis and Fragaria virginiana), the progenitor species of cultivated strawberry. Substantial variation is identified...
Revisiting the origin of octoploid strawberry | Nature Genetics
2019年12月16日 · The cultivated strawberry (Fragaria × ananassa) is an octoploid, and the identity of its four subgenomes has long
Evolutionary Origins and Dynamics of Octoploid Strawberry …
Here, we use dense linkage maps generated with targeted sequence capture to improve the diploid strawberry (Fragaria vesca) reference genome and to disentangle the subgenomes of …
Frontiers | Genome Synteny Has Been Conserved Among the Octoploid …
2020年2月6日 · Using comparative genomics, we show that geographically diverse wild octoploids are effectively diploidized, nearly completely collinear, and retain strong macro-synteny with diploid progenitor species.
A roadmap for research in octoploid strawberry - PMC
The cultivated strawberry (Fragaria × ananassa) is an allo-octoploid species, originating nearly 300 years ago from wild progenitors from the Americas. Since that time the strawberry has become the most widely cultivated fruit crop in the world, ...
The origin and subgenome dynamics of the octoploid strawberries …
Identifying the diploid progenitors of the octoploid will illuminate the environment and potential selective forces experienced by each subgenome prior to their merger into a single genome. This legacy has shaped the genetic variation available for …
