Xanthomonas translucens is a group of gram‐negative bacteria that can cause important diseases in cereal crops and forage grasses. Different pathovars have been defined according to their host ranges, and molecular and biochemical characteristics. Pathovars have been placed into two major groups: translucens and graminis. The translucens group contains the pathovars causing bacterial leaf streak (BLS) on cereal crops such as wheat, barley, triticale, rye, and oat. In recent years, BLS has re‐emerged as a major problem for many wheat‐ and barley‐producing areas worldwide. The biology of the pathogens and the host–pathogen interactions in cereal BLS diseases were poorly understood. However, recent genome sequence data have provided an insight into the bacterial phylogeny and identification and pathogenicity/virulence. Furthermore, identification of sources of resistance to BLS and mapping of the resistance genes have been initiated.

Xanthomonas translucens的translucens组：复杂且重要的病原体，导致谷物上的细菌叶片出现条纹。

半透明黄单胞菌是一组革兰氏阴性细菌，可以在谷物作物和牧草中引起重要疾病。根据其寄主范围以及分子和生化特征定义了不同的病原体。探伤者被分为两大类：半透明和白痴。半透明的糖类包含引起小麦，大麦，黑小麦，黑麦和燕麦等谷物作物上细菌叶条纹（BLS）的病原菌。近年来，对于世界上许多小麦和大麦产区，BLS再次成为一个主要问题。人们对谷物BLS疾病中病原体的生物学和宿主-病原体之间的相互作用了解甚少。然而，最近的基因组序列数据提供了对细菌系统发育和鉴定以及致病性/毒力的见解。此外，
