| pathotypes and genetic relationship of worldwide collections of elsinoë spp. causing scab diseases of citrus. | two scab diseases are recognized currently on citrus: citrus scab, caused by elsinoë fawcettii, and sweet orange scab, caused by e. australis. because the two species cannot be reliably distinguished by morphological or cultural characteristics, host range and molecular methods must be used to identify isolates. four pathotypes of e. fawcettii and two of e. australis have been described to date based on host range. the host specificity and genetic relationships among 76 isolates from argentina, ... | 2009 | 19453232 |
