Whole-Genome Sequencing of Acer catalpifolium Reveals Evolutionary History of Endangered Species.

ABSTRACT: Acer catalpifolium is an endangered species restricted to remote localities of West China. Understanding the genomic content and evolution of A. catalpifolium is essential to conservation efforts of this rare and ecologically valuable plant. Here, we report a high-quality genome of A. catalpifolium consisting of ∼654 Mbp and ∼35,132 protein-coding genes. We detected 969 positively selected genes in two Acer genomes compared with four other eudicots, 65 of which were transcription factors. We hypothesize that these positively selected mutations in transcription factors might affect their function and thus contribute to A. catalpifolium's decline-type population. We also identified 179 significantly expanded gene families compared with 12 other eudicots, some of which are involved in stress
