Abstract

Bamboo mosaic virus (BaMV) is a well-characterized virus and a model of virus-host interaction in plants. Here, we identified naturally occurring BaMV isolates from Fujian Province, China and furthermore describe a naturally occurring BaMV coinfection in bamboo (Bambusa xiashanensis) plants. Two different types of BaMV were identified, represented by isolates BaMV-XSNZHA7 (X7) and BaMV-XSNZHA10 (X10). The phylogenetic relationships between X7- and X10-like isolates and published BaMV isolates were determined based on genomic RNA and amino acid sequences. Three clusters were identified, indicating that BaMV is highly diverse. The in planta viral replication kinetics were determined for X7 and X10 in single infections and in an X7/X10 coinfection. The peak viral load during coinfection was significantly greater than that during single infection with either virus and contained a slightly higher proportion of X10 virus than X7, suggesting that X10-like viruses may have a fitness advantage when compared to X7-like viruses.
