In 1993, Mark Chase and 41 coauthors published phylogenetic analyses of two very large data sets of nucleotide sequences of the chloroplast gene rbcL, which encodes the large subunit of ribulose 1,5-bisphosphate carboxylase. Their paper was important for several reasons. These analyses were (and still are) among the largest ever attempted using parsimony. The assembly of such a large number of ...

background: saffron (crocus sativus l.) is a common but very expensive herbal medicine. as an important traditional medicine, it has an outstanding effect in treating irregular and painful menstruation. recently, the over-demand tendency of saffron results in an unusual phenomenon in the medicinal markets. adulterants and saffron-like substitutes are intentionally mixed into medicinal markets a...

Plastids are usually uni-parentally inherited and genetic recombination between these organelles is seldom observed. The genus Pseudo-nitzschia, a globally relevant marine diatom, features bi-parental plastid inheritance in the course of sexual reproduction. This observation inspired the recombination detection we pursued in this paper over a ~1,400-nucleotide-long region of the plastidial rbcL...

How AAA+ chaperones conformationally remodel specific target proteins in an ATP-dependent manner is not well understood. Here, we investigated the mechanism of the AAA+ protein Rubisco activase (Rca) in metabolic repair of the photosynthetic enzyme Rubisco, a complex of eight large (RbcL) and eight small (RbcS) subunits containing eight catalytic sites. Rubisco is prone to inhibition by tight-b...

Data is presented in support of a phylogenetic reconstruction of the species-rich early-divergent angiosperm genus Goniothalamus (Annonaceae) (Tang et al., Mol. Phylogenetic Evol., 2015) [1], inferred using chloroplast DNA (cpDNA) sequences. The data includes a list of primers for amplification and sequencing for nine cpDNA regions: atpB-rbcL, matK, ndhF, psbA-trnH, psbM-trnD, rbcL, trnL-F, trn...

We examine rate heterogeneity among evolutionary lineages of the grass family at two plasmid loci, ndhF and rbcL, and we introduce a method to determine whether patterns of rate heterogeneity are correlated between loci. We show both that rates of synonymous evolution are heterogeneous among grass lineages and that are heterogeneity is correlated between loci at synonymous sites. At nonsynonymo...
