Progress in chloroplast genome analysis of herbage

Chloroplasts of plant is an important organelle of photosynthesis and energy conversion and its also an important carrier of female genetic information. Chloroplast genome information is valuable in revealing the evolution of species, hybrids, evolution, species identification and other aspects. With the rapid development of plant chloroplast genome research, researches in herbage chloroplast genome are also executed by leaps and bounds whereas some herbage have not been studied indepth and only limited in the chloroplast genome sequences. As the importance of chloroplast genome research, the recent relevant information was collected and the latest research progress was summarized in this field from several aspects including isolation of chloroplast DNA, purification, sequencing to understand more about chloroplast DNA purification and the research of status, future trends and prospects of forage chloroplast genome.
