Xylella fastidiosa is a fastidious, xylem-limited bacterium that causes a range of economically important plant diseases. Here we report the complete genome sequence of X. fastidiosa clone 9a5c, which causes citrus variegated chlorosis--a serious disease of orange trees. The genome comprises a 52.7% GC-rich 2,679,305-base-pair (bp) circular chromosome and(More)
Despite the intense interest in the metabolic regulation and evolution of the ATP-producing pathways, the long standing question of why most multicellular microorganisms metabolize glucose by respiration rather than fermentation remains unanswered. One such microorganism is the cellulolytic fungus Trichoderma reesei (Hypocrea jecorina). Using EST analysis(More)
Human growth hormone was expressed in transgenic tobacco seeds using the monocot tissue-specific promoter from sorghum γ-kafirin seed storage protein gene. During tobacco seed ripening, the expressed hormone was directed to the endoplasmic reticulum by a signal peptide from a Coix prolamin and was secreted into the apoplastic space, where it accounted for(More)
Oxygen is essential for the survival of obligatorily aerobic eukaryotic microorganisms, such as the multicellular fungus Trichoderma reesei. However, the molecular basis for the inability of such cells to survive for extended periods under anoxic conditions is not fully understood. Using cDNA microarray analysis, we show that changes in oxygen availability(More)
The filamentous fungus Trichoderma reesei is adapted to nutrient-poor environments, in which it uses extracellular cellulases to obtain glucose from the available cellulose biomass. We have isolated and characterized Trhxt1, a putative glucose transporter gene, as judged by the glucose accumulation phenotype of a DeltaTrhxt1 mutant. This gene is repressed(More)
