Bacterial epiphytes isolated from marine eukaryotes were screened for the production of quorum sensing inhibitory compounds (QSIs). Marine isolate KS8, identified as a Pseudoalteromonas sp., was found to display strong quorum sensing inhibitory (QSI) activity against acyl homoserine lactone (AHL)-based reporter strains Chromobacterium violaceum ATCC 12472 and CV026. KS8 supernatant significantl...

Flag leaves of KS8 sorghum (Sorghum bicolor (L.) Moench] are low in dhurrin (p-hydroxy-(S)-mandelonitrile-p-D-glucosidel content and thus in hydrocyanic acid potential (HCN-p), and they contain little (if any) leucoanthocyanidin (LAC). Comparable leaves of 'Colman' sorghum are intermediate in HCN-p and high in LAC. This study was conducted to investigate the inheritance of HCN-p and LAC in cros...

Seedlings of both KS8 and N32 sorghum [Sorghum bicolor (L.) Moench] were high in dhurrin [p-hydroxy-(S)-mandelonitrile-BD-glucoside] and thus in hydrocyanic acid potential (HCN-p), but the HCN-p of mature leaves from field-grown plants of KS8 was only about one-tenth as high as that of N32. A study of the inheritance of this large difference between KS8 and N32 revealed that a single major gene...

Tissue disruption caused by freezing and thawing may contribute to rapid enzymatic breakdown of dhurrin [p-hydroxy-(S)mandelonitrile-p-D-glucoside], the cyanogenic glucoside of sorghum [Sorghum bicolor (L.) Moench], but published reports arenot in agreement as to the effects of freezing on the hydrocyanic acid potential (HCN-p) of field-grown sorghum leaves. Theseeffects were investigated in a ...

The publication in 2001 by Adcock et al. [Adcock GJ, et al. (2001) Proc Natl Acad Sci USA 98(2):537-542] in PNAS reported the recovery of short mtDNA sequences from ancient Australians, including the 42,000-y-old Mungo Man [Willandra Lakes Hominid (WLH3)]. This landmark study in human ancient DNA suggested that an early modern human mitochondrial lineage emerged in Asia and that the theory of m...

BACKGROUND Human cutaneous infection caused by a homogeneous group of keratinophilic fungi called dermatophytes. These fungi are the most common infectious agents in humans that are free of any population and geographic area. Microsporum canis is a cause of dermatophytosis (Tinea) in recent years in Iran and atypical strain has been isolated in Iran. Its cases occur sporadically due to M. canis...
