DOI: 10.1007/s00239-017-9792-x
Abstract: This study represents the most comprehensive plastome-wide comparison of nucleotide substitution rates across the three subfamilies of Fabaceae: Caesalpinioideae, Mimosoideae, and Papilionoideae. Caesalpinioid and mimosoid legumes have large, unrearranged plastomes compared with papilionoids, which exhibit… read more here.

DOI: 10.1007/s00239-019-09916-1
Abstract: Twenty-nine DNA regions of plastid origin have been previously identified in the mitochondrial genome of Cucurbita pepo (pumpkin; Cucurbitaceae). Four of these regions harbor homolog sequences of rbcL, matK, rpl20–rps12 and trnL–trnF, which are widely… read more here.

DOI: 10.1038/s41598-018-31938-w
Abstract: We generated a complete plastid genome (plastome) sequence for Lamprocapnos spectabilis, providing the first complete plastome from the subfamily Fumarioideae (Papaveraceae). The Lamprocapnos plastome shows large differences in size, structure, gene content, and substitution rates… read more here.

DOI: 10.1186/s12870-022-03515-x
Abstract: Background Comparative genomic analysis exhibits dynamic evolution of plastid genome (plastome) in the clusioid clade of Malpighiales, which comprise five families, including multiple inversions and gene losses. Little is known about the plastome evolution in… read more here.

DOI: 10.3389/fmolb.2021.626042
Abstract: Bivalves represent valuable taxonomic group for aging studies given their wide variation in longevity (from 1–2 to >500 years). It is well known that aging is associated to the maintenance of Reactive Oxygen Species homeostasis… read more here.

DOI: 10.3390/ijms24043808
Abstract: The Vanilloideae (vanilloids) is one of five subfamilies of Orchidaceae and is composed of fourteen genera and approximately 245 species. In this study, the six new chloroplast genomes (plastomes) of vanilloids (two Lecanorchis, two Pogonia,… read more here.
