Comparative Analysis of Chloroplast Genome Sequences and Phylogeny in Three <i>Macadamia integrifolia</i> Cultivars.

ABSTRACT: Background/Objectives: Macadamia integrifolia is a valuable subtropical fruit tree, yet genomic studies on its cultivars are limited. This study aims to elucidate the chloroplast genome features, variations, and phylogenetic relationships of three main cultivars ('Guilin No. 1', 'Nanya No. 1', 'Qian'ao No. 1') to support germplasm identification and breeding. Methods: chloroplast genomes of three M. integrifolia cultivars from Guangxi, Guangdong, and Guizhou were sequenced using Illumina technology, followed by assembly, annotation, and comparative analyses of structure, repeats, and codon usage. Phylogenetic relationships were reconstructed using complete genome sequences. Results: The three chloroplast genomes displayed typical quadripartite structures,
