Diversity and host association of the tropical tree endophyte Lasiodiplodia theobromae revealed using simple sequence repeat markers

Abstract: Lasiodiplodia theobromae is a cosmopolitan fungus with a worldwide distribution in the tropics and subtropics, where it causes shoot blight and dieback of trees and shrubs and imparts blue stain in timber In this study, eight simple sequence repeat (SSR) markers were used to evaluate the genetic diversity and gene flow between populations of L theobromae The relationships between isolates from different hosts were considered using three populations from different tree species in Venezuela (VEN) and the relationships between isolates from different geographical origins included populations from VEN, South Africa (RSA) and Mexico (MEX) A small number of predominant genotypes were encountered in the VEN and RSA populations and thus genotypic diversity was low There was no evidence of host specificity for isolates of L theobromae and there was very high gene flow between populations from different hosts Geographical isolation existed between populations of the pathogen from different regions, with unique alleles fixed in the different populations Gene flow was, however, less restricted between isolates from MEX and the other populations, consistent with MEX as a common source of seed in both VEN and RSA Genetic analysis suggested predominantly clonal reproduction with some genotypes widely distributed within a region The broad host range of L theobromae and the lack of evidence for host specialization, coupled with its endophytic nature and the common appearance of symptoms only after harvest, is likely to hinder disease management strategies

Measurement of the Inclusive Jet Cross Section in pp Collisions at √s= 7 TeV

Abstract: The inclusive jet cross section is measured in pp collisions with a center-of-mass energy of 7 TeV at the LHC using the CMS experiment. The data sample corresponds to an integrated luminosity of 34 inverse picobarns. The measurement is made for jet transverse momenta in the range 18-1100 GeV and for absolute values of rapidity less than 3. The measured cross section extends to the highest values of jet pT ever observed and, within the experimental and theoretical uncertainties, is generally in agreement with next-to-leading-order perturbative QCD predictions.
