Example sentences for: rostochiensis

How can you use “rostochiensis” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Following isolation from G. rostochiensis and H. glycines [ 5 ] , cellulases have been identified in M. incognita [ 6 ] , G. tabacum [ 68 ] , H. schachtii [ 69 ] , and P. penetrans [ 70 ] . Additional prokaryotic-like sequences identified in plant parasitic nematodes include other cell-wall-degrading enzymes such as xylanase [ 7 ] , pectate lyase [ 8 71 ] and polygalacturonase [ 72 ] , and evidence is accumulating that these sequences have been acquired by horizontal gene transfer [ 11 ] . The known Meloidogyne cellulase (MI00483.cl), potentially novel cellulases (MI00537.cl, MI01196.cl, MI01381.cl, MI01842.cl), and pectate lyase (MI00592.cl, MI00520.cl) were represented in the M. incognita EST clusters.

  • Another RKN gene also postulated to have been acquired by HGT, and which encodes polyglutamate synthetase, was previously identified in M. artiellia [ 23 ] . Significantly, hybridization data showed that this particular gene is absent from both the M. javanica and G. rostochiensis genomes [ 23 ] . We speculate that acquisition of this gene by M. artiellia is a recent HGT event (event 'c', Figure 1), and thus it is truly absent from the Meloidogyne genomes from which our datasets were derived.

  • Sixty-four ESTs had significant homology to the putative fatty-acid-binding protein Sec-2, confirming the abundant expression of this gene reported in L2 cDNA libraries from M. incognita [ 29 ] and the cyst nematodes G. rostochiensis and G. pallida cDNA [ 30 ] . Sec-2 is secreted by plant-parasitic nematodes at relatively high levels [ 34 ] . Several abundantly expressed genes are also horizontal gene transfer candidates (see below).

  • The most extensively studied HGT candidates are four genes encoding β-1,4-endoglucanase, initially identified in the cyst nematodes G. rostochiensis and H. glycines [ 18 19 ] . These four genes (NemaGene Contig IDs MI00537, MI01011, MI01381 and MI01842) [ 30 ] appear to define two sets of paralogs formed before divergence of the cyst and root-knot nematodes.

  • Use of SL1 by transcripts is estimated at 70% in C. elegans [ 60 ] , more than 80% in Ascaris lumbricoides [ 61 ] , and approximately 60% in G. rostochiensis (Ling Qin, personal communication).
