PY - 2009 DA - 2009/03/16 TI - Population-specific gene expression in the plant pathogenic nematode Heterodera glycines exists prior to infection and during the onset of a resistant or susceptible reaction in the roots of the Glycine max genotype Peking JO - BMC Genomics SP - 111 VL - 10 IS - 1 AB - A single Glycine max (soybean) genotype (Peking) reacts differently to two different populations of Heterodera glycines (soybean cyst nematode) within the first twelve hours of infection during resistant (R) and susceptible (S) reactions. This suggested that H. glycines has population-specific gene expression signatures. A microarray analysis of 7539 probe sets representing 7431 transcripts on the Affymetrix® soybean GeneChip® were used to identify population-specific gene expression signatures in pre-infective second stage larva (pi-L2) prior to their infection of Peking. Other analyses focused on the i nfective L2 at 12 h ours post infection (i-L212h), and the i nfective sedentary stages at 3 d ays post infection (i-L23d) and 8 d ays post infection (i-L2/L38d).
