About this Research Topic
With the rapid development of sequencing technologies, especially the application of high-throughput sequencing, the whole genome sequences of chloroplasts and mitochondria could be obtained both efficiently and accurately. This offers a valuable opportunity for the analysis and exploitation of a broad range of organelle genomes. Plant organelle genomes possess unique structures and features, which are typically small and monoplex. For example, the chloroplast genome is relatively small but encodes numerous genes related to photosynthesis. While the mitochondrial genome is relatively large with many genes related to processes included, such as energy metabolism and apoptosis, suggesting that these organelles play an important role in plant growth and development, as well as in responding to environmental changes. Although the organelle genome is somewhat genetically autonomous, it also falls under the regulation of the nuclear genome. Numerous repetitive sequences and non-coding regions in the organelle genomes make the task of researching organelle genomes uniquely challenging and rewarding.
Despite the remarkable advancement in plant organelle genome research, the numerous aspects still require further exploration. For instance, the inheritance and variation patterns of organelle genomes need to be further investigated. In addition, the development and potential application of molecular markers grounded on organelle genomes need enhancement. Moreover, our comprehension of the functions of some obscure genes in organelle genomes is shallow, the interaction mechanism between organelle genomes and nuclear genomes remains unresolved, and organelle genome editing technology is still nascent and subject to further improvements and optimization.
The aim of this research topic is to delve into how to leverage the unique structural and genetic properties of chloroplast/mitochondrial genomes for advancing their applications in the realms of plant evolution and breeding. We welcome the submission of original research articles, reviews, and mini-reviews related to, but not limited to, the following topics:
• Development and application of molecular markers based on organelle genomes.
• Pan-organelle genome research.
• Research into organelle genome editing.
• Research into the functional genes of organelle genomes.
