Chronological colonization profile of P. cajani in root tissues of inoculated pigeonpea (cv. ICP 7119) seedlings grown in three different CO 2 conditions, ambient, 550 ppm and 700 ppm respectively. Absolute quantification of fungal DNA was determined in real time PCR assay using ITS sequences of 5.8S rDNA. Error bar represents the standard error of three biological replicationsat the 95% confidence interval.
