Chromosome morphology in the pasture legume Lotononis bainesii Baker and the related species Lotononis angolensis Welwitsch ex Baker.

Nodule morphology, symbiotic specificity and association with unusual rhizobia are distinguishing features of the genus Listia within the Southern African crotalarioid clade Lotononis s.l.

BACKGROUND AND AIMS The legume clade Lotononis sensu lato (s.l.; tribe Crotalarieae) comprises three genera: Listia, Leobordea and Lotononis sensu stricto (s.s.). Listia species are symbiotically specific and form lupinoid nodules with rhizobial species of Methylobacterium and Microvirga. This work investigated whether these symbiotic traits were confined to Listia by determining the ability of...

Characterization of pigmented methylotrophic bacteria which nodulate Lotononis bainesii.

Root nodule isolates from a shrubby legume, Lotononis bainesii, were characterized by 16S rRNA gene sequencing and morphologically by substrate utilization patterns. The symbiotic genome of these isolates was analysed by partial sequencing of the nifH gene. Based on the results of numerical taxonomy, the isolates formed a closely related cluster, showing no correspondence to any of the known rh...

The Peano-baker Series

Abstract. This note reviews the Peano-Baker series and its use to solve the general linear system of ODEs. The account is elementary and self-contained, and is meant as a pedagogic introduction to this approach, which is well known but usually treated as a folklore result or as a purely formal tool. Here, a simple convergence result is given, and two examples illustrate that the series can be u...

Rhizome Extract from Kaempferia parviflora Wall. ex. Baker Induces Apoptosis

Kaempferia parviflora Wall. ex. Baker is a member of the ginger family (Zingiberaceae). In folk medicine of Suriname and Southeast Asia, rhizome is used for treatment of swelling, wounds and diarrhea colic disorder, and as an aphrodisiac (Yenjai et al., 2004). Rhizomes of fingerroot or K. parviflora Wall. ex. Baker are used as food ingredients and made into wine (Nagahara et al., 2002). Alcohol...
