Example sentences for: root-knot
How can you use “root-knot” in a sentence? Here are some example sentences to help you improve your vocabulary:
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.
The generation of expressed sequence tags (ESTs) by single-pass random sequencing of cDNA libraries is a powerful tool for rapid gene transcript identification in metazoans [ 14 15 16 17 ] including parasitic nematodes of humans and animals [ 18 19 20 21 22 23 ] . High-throughput projects on two dozen nematode species have now brought the total number of publicly available roundworm ESTs to nearly 400,000, with half the sequences coming from parasites [ 24 25 26 27 ] . As a part of these efforts, EST sequencing from plant parasitic nematodes is in progress [ 28 ] and pilot EST datasets from the root-knot nematode M. incognita and the cyst nematodes Globodera rostochiensis and G. pallida second-stage larvae have recently been analyzed [ 29 30 ] .
Both basic understanding of root-knot nematode biology and applied research toward new means of nematode control are now beginning to benefit from the rapid identification of transcribed genes in the species.
It is possible that root-knot nematodes have adapted a portion of Nod factor biology to the induction of feeding sites, rather than nodules, in plants.
MI00244.cl, for example, had homology to 47 ESTs in our collection from other Tylenchida species including root-knot nematodes M. javanica, M. hapla and M. arenaria , cyst nematodes H. glycines and G. rostochiensis , and the lesion nematode Pratylenchus penetrans with E-values from 7e-78 to 3e-05.
