vasinfectum by directional selection only in few years,mRNA differential display method was used to study the differently expressed cDNAs between susceptible cotton variety(Tianjiu63) and its resistant descendants obtained by directional selection in disease plot in this study.

To better understand the population dynamics of the pathogens at disease nursery and field, we studied the pathogens population at two disease nurseries located in Shanghang and Jiangle counties and their nearby fields with virulence analysis based on CO39 near isogenic lines (CO39 NILs) and DNA fingerprint patterns defined by a repetitive element (Pot-2) based polymerase chain reaction (rep-PCR).
