Gene family expansions and contractions
WebOct 6, 2024 · Gene family expansions and contractions in addition to genome inflation via long terminal repeat (LTR) retrotransposon insertions were implicated as an important driver of O. sinensis divergence. The insertion rate of LTR sequences into the O. sinensis genome peaked ~ 30–40 Mya, when the Tibetan Plateau rose rapidly. WebInfer gene family counts at all internal nodes (ancestral populations) of the phylogeny provided as input. By comparing different nodes in the phylogeny, the user will be able to tell along which branches gene families have contracted or expanded.
