Structural variation and evolution of chloroplast tRNAs in green algae.

ABSTRACT: As one of the important groups of the core Chlorophyta (Green algae), Chlorophyceae plays an important role in the evolution of plants. As a carrier of amino acids, tRNA plays an indispensable role in life activities. However, the structural variation of chloroplast tRNA and its evolutionary characteristics in Chlorophyta species have not been well studied. In this study, we analyzed the chloroplast genome tRNAs of 14 species in five categories in the green algae. We found that the number of chloroplasts tRNAs of Chlorophyceae is maintained between 28-32, and the length of the gene sequence ranges from 71 nt to 91 nt. There are 23-27 anticodon types of tRNAs, and some tRNAs have missing anticodons that are compensated for by other types of anticodo
