xylella造句

• Scientists are mapping the genome of the Xylella fastidiosa bacterium, testing natural substances that discourage the sharpshooter from feeding and examining how changes to nutrient levels can boost a vine's resistance.
• The extensive rhizomes help prevent erosion by stabilizing streambanks . " A . douglasiana " is susceptible to infection by " Xylella fastidiosa " which causes Pierce's disease.
• So though the diseases caused by xylella can be severe _ in California, vineyards lose tens of millions of dollars each year to the bacterium _ little was known about the biology of this bug.
• Last July, a Brazilian consortium organized and financed by the foundation became the first anywhere to decode the genome of a plant pathogen, Xylella fastidiosa, an insect-borne bacteria that infests oranges.
• But researchers said xylella's completion was worth a bit of hoopla as it marks not only the revelation of a new genome, but the entry of a surprising new player in a field dominated by developed nations.
• Pierce's disease is caused by Xylella fastidiosa, a bacterium that infects the tissue which carries water from a plant's roots to its leaves, and whose genome was unravelled by researchers in Brazil earlier this year.
• In fact xylella's sequence is small, a mere one-thousandth the size of the human genome, and 24 bacteria ( not causing plant disease ) had already beat it to the finish line with little fanfare in their respective countries.
• It has also been studied in gram-negative species found in soil such as " Pseudomonas stutzeri ", " Acinetobacter baylyi ", and gram-negative plant pathogens such as " Ralstonia solanacearum " and " Xylella fastidiosa ".
• A microbial plant parasite, " Xylella fastidiosa ", is carried by this species, and is linked to many plant diseases, including phoney peach disease in the southern United States, oleander leaf scorch and Pierce's disease in California, and citrus X disease ( citrus variegated chlorosis ) in Brazil.
• Though other genome-sequencing efforts _ for example, in humans or the laboratory staple fruit fly _ have attracted more attention, the Brazilian target, an odd little bacterium known as Xylella fastidiosa, distinguishes itself as the first to be decoded of the countless nasty species that together cost farmers and foresters many billions of dollars each year.
• He participates in two consortia coordinated by FAPESP, a science foundation in the State of S . Paulo, and the Ludwig Institute for Cancer Research ( LICR ) : the sequencing of the Xylella fastidiosa genome, the first phytopathogen whose genome was completely sequenced, and the FAPESP / LICR Human Cancer Genome Project, that studied the gene expression in human neoplastic tissues, and generated one of the largest contributions of gene expression to public databases.
