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...
متن کاملChromosome Number Variation in Iranian Populations of Acorus calamus
Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...
متن کاملNodule 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...
متن کاملKaryotype analysis and new chromosome number reports for nine Vicia species in Iran
This study concerns diploid chromosome numbers and karyotype analysis of nine species belonging to four sections (Vicilla, Cracca, Variegata and Anatropostylia) of the subgenus Vicilla of the genus Vicia (Fabaceae). The chromosome numbers of Vicia alpestris subsp. hypoleuca, V. aucheri, V. ciceroideae, V. gariensis, V. iranica, V. koeieana, V. rechingeri, V. sojakii and V. venulosa are reported...
