A chloroplast phylogeny of Arisaema (Araceae) illustrates Tertiary floristic links between Asia, North America, and East Africa [PDF]
, 2004 The evolution of Arisaema is reconstructed, based on combined sequences (2048 aligned bases) from the chloroplast trnL intron, trnL-trnF spacer, and rpl20-rps12 spacer obtained for species from all 11 sections, including sectional type species and ...

Can DNA from wet, temperate soils be used for palaeoecological reconstruction?
Journal of Quaternary Science, EarlyView.ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

Functional specialization amongst the Arabidopsis Toc159 family of chloroplast protein import receptors [PDF]
, 2004 The initial stages of preprotein import into chloroplasts are mediated by the receptor GTPase Toc159. In Arabidopsis thaliana, Toc159 is encoded by a small gene family: atTOC159, atTOC132, atTOC120, and atTOC90.

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security
Journal of the Science of Food and Agriculture, EarlyView.Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Proton gradients and proton-dependent transport processes in the chloroplast
Frontiers in Plant Science, 2016 Proton gradients are fundamental to chloroplast function. Across thylakoid membranes, the light induced proton gradient is essential for ATP synthesis.

Chloroplast RNA polymerases: Role in chloroplast biogenesis
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2015 Plastid genes are transcribed by two types of RNA polymerase in angiosperms: the bacterial type plastid-encoded RNA polymerase (PEP) and one (RPOTp in monocots) or two (RPOTp and RPOTmp in dicots) nuclear-encoded RNA polymerase(s) (NEP). PEP is a bacterial-type multisubunit enzyme composed of core subunits (coded for by the plastid rpoA, rpoB, rpoC1 ...
