Patterns of protein synthesis in the budding yeast cell cycle: variable or constant?

Proteins are the principal macromolecular constituent of proliferating cells, and protein synthesis is viewed as a primary metric of cell growth. While there are celebrated examples of proteins whose levels are periodic in the cell cycle (e.g.

Isolation of High-Molecular-Weight (HMW ) DNA from Fusarium oxysporum for Long-Read Sequencing.

In many instances Fusarium oxysporum genomes are complex and challenging to assemble mainly due to the increased number of repetitive elements and variable numbers of supernumerary chromosomes, which are primarily associated with pathogenicity. Hence, to obtain the accurate F. oxysporum genome assembly and high-resolution sequence information, protocols for versatile, reliable, and high recovery of high-quality DNA for diverse sequencing platforms are instrumental.

Genome analysis of multi- and extensively-drug-resistant tuberculosis from KwaZulu-Natal, South Africa.

The KZN strain family of Mycobacterium tuberculosis is a highly virulent strain endemic to the KwaZulu-Natal region of South Africa, which has recently experienced an outbreak of extensively-drug resistant tuberculosis. To investigate the causes and evolution of drug-resistance, we determined the DNA sequences of several clinical isolates--one drug-susceptible, one multi-drug resistant, and nine extensively drug-resistant--using whole-genome sequencing. Analysis of polymorphisms among the strains is consistent with the drug-susceptibility profiles, in that well-known mutations are observed that are correlated with resistance to isoniazid, rifampicin, kanamycin, ofloxacin, ethambutol, and pyrazinamide.

Simple sequence repeat markers useful for sorghum downy mildew (Peronosclerospora sorghi) and related species.

Background: A recent outbreak of sorghum downy mildew in Texas has led to the discovery of both metalaxyl resistance and a new pathotype in the causal organism, Peronosclerospora sorghi. These observations and the difficulty in resolving among phylogenetically related downy mildew pathogens dramatically point out the need for simply scored markers in order to differentiate among isolates and species, and to study the population structure within these obligate oomycetes. Here we present the initial results from the use of a biotin capture method to discover, clone and develop PCR primers that permit the use of simple sequence repeats (microsatellites) to detect differences at the DNA level.

Characterization and genetic distance analysis of isolates of Peronosclerospora sorghi using AFLP fingerprinting.

Sorghum downy mildew, caused by the obligate oomycete Peronosclerospora sorghi, has been controlled through the use of resistant cultivars and seed treatment with metalaxyl. A recent outbreak in fields planted with treated seed revealed the presence of a metalaxyl-resistant variant. Here, 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.
