Abstract:

Most plant chloroplast genomes are double-stranded circular DNA with a conserved tetrad structure, non-recombination, haploid, uniparental inheritance, moderate evolutionary rate, and highly conserved sequence and structure, and may provide useful information for the evolution of plants. Due to abundant tea germplasm resources, their complex origin, evolution and classification remain largely elusive, resulting in hindering their efficient protection and innovative utilization. In recent, the rapid development of chloroplast genome sequencing technologies has been greatly promoted and being changed into the third-generation sequencing. About 33 sequenced chloroplast genomes from tea plants have been published on NCBI, and the gene types and gene sequence characteristics of chloroplast genomes in tea plants have been partially revealed, and used in the study of classification, identification, origin, evolution, and albino mechanism for tea plants. However, many chloroplast genomes of tea resources remain undeciphered. While reviewing the origin, inheritance, and basic characteristics of plant chloroplast genomes, the paper focused on the review of the sequencing technology, genomic features, gene types, and gene sequences of the published chloroplast genomes from tea plants. The paper briefly presented the application status of tea plant chloroplast genome and finally, and discussed the future application and development direction of tea plant chloroplast genomes.
