Here, we present the first complete chloroplast genome of (154,018 bp), which exhibits a typical quadripartite structure, including an LSC (83,966 bp), SSC (18,910 bp), and two IRs (25,571 bp each). A total of 133 genes were annotated, with 114 unique genes and 19 duplicated in the IRs. .Phylogenetic analyses based on complete chloroplast genomes of 13 species strongly supported as sister to (BS = 100%, PP = 1.0), challenging earlier studies that suggested a sister relationship with based on partial plastid sequences. Overall, this study provides a critical genomic resource for advancing research on the taxonomy, evolution, and medicinal breeding of .

Linnaeus 1753 is a herbaceous perennial medicinal plant of the family Scrophulariaceae, native throughout eastern and central North America. In this study, the first complete chloroplast genome of was reported and phylogenetic analysis was conducted with other 11 species from Scrophulariaceae. The chloroplast genome was 152,414 bp with 132 genes and includes a large single-copy (LSC) region (83,583 bp), a small single-copy (SSC) region (17,925 bp), and a pair of inverted repeat (IRs) regions (25,453 bp).

Introduction: Rice is mainly consumed by half of the world's population. The imminent climate change and population growth expected in the next 30 years will outpace the current rice production capacity, posing risks to food and nutrition security in developing nations. One simplified approach to address this challenge is to improve photosynthetic capacity by increasing chlorophyll content in leaves and stems.

Background: Advances in DNA sequencing technology have led to a rapid increase in the number of species with organelle genomes and even complete nuclear genomes being sequenced. Thousands of plastid genomes from across all major clades of land plants are now available, and one of the surprising findings is the recurring event of complete or functional loss of genes involved in cyclic electron transport during photosynthesis - the ndh genes that encode subunits of the chloroplast NADH dehydrogenase-like (NDH) complex. Gene loss in non-photosynthetic, heterotrophic plants may be expected, but the increasing number of losses being discovered in autotrophic plants questions the role and potential dispensability of the ndh genes and the entire NDH complex.
