Genome Analysis of Multi- and Extensively-Drug-Resistant Tuberculosis from KwaZulu-Natal, South Africa
Analysis of polymorphisms among the strains shows that well-known mutations are observed that are correlated with resistance to isoniazid, rifampicin, kanamycin, ofloxacin, ethambutol, and pyrazinamide, supporting the theory that this represents a case of clonal expansion. Expand
Microarray analysis of genes preferentially expressed in differentiating xylem of loblolly pine (Pinus taeda)
This work compared transcript profiles of differentiating loblolly pine xylem with needles, megagametophytes, and embryos to understand the molecular basis for temporal and spatial regulation of xylogenesis and the effect of the expression of individual genes on physical and chemical properties of wood.

Simple sequence repeat markers useful for sorghum downy mildew (Peronosclerospora sorghi) and related species
This is the first attempt to extensively develop SSR markers from Peronosclerospora genomic DNA and can be readily used to distinguish isolates within several species of the oomycetes that cause downy mildew diseases. Expand
Genetic diversity and pathotype determination of Colletotrichum sublineolum isolates causing anthracnose in sorghum
Amplified fragment length polymorphism (AFLP) based genetic diversity was analyzed for 232 Colletotrichum sublineolum isolates collected between 2002 and 2004 from three geographically distinctExpand
Purification and cloning of an arabinogalactan-protein from xylem of loblolly pine
An arabinogalactan-protein was purified from differentiating xylem of loblolly pine and the N-terminal sequence used to identify a cDNA clone, which hypothesized to contain a GPI (glycosylphosphatidylinositol) anchor site. Expand
Characterization and genetic distance analysis of isolates of Peronosclerospora sorghi using AFLP fingerprinting.
PCR-based methods including amplification from RAPD primers and two systems of automated AFLP analysis have been used to detect DNA-level genetic variation among 14 isolates including metalaxyl-resistant and susceptible isolates, as well as representatives of common pathotypes 1 and 3 and a new pathotype.

cDNAs induced by ozone from Atriplex canescens (saltbush) and their response to sulfur dioxide and water‐deficit
Data indicate that woody plant genes associated with cell wall protein production and whose expression is induced by several stress factors may be responding to common oxidative stress pathways. Expand
In vitro regeneration of fourwing saltbush [Atriplex canescens (Pursh) Nutt.].
The successful production of plantlets using both leaf-disc and axillary-bud methods demonstrates that this important range species can be mass propagated in vitro. Expand
Hormonal and developmental regulation of two arabinogalactan-proteins in xylem of loblolly pine (Pinus taeda)
The results indicate that PtX3H6 and PtX14A9 are differently regulated during seedling development and that these differences may be mediated by different hormonal signaling. Expand
Sequences upstream and downstream of two xylem-specific pine genes influence their expression.
The identification of regulatory elements conferring high levels of expression in differentiating pine xylem will be valuable for genetic engineering of wood properties and will contribute to ourExpand
