[Evaluation of pre-harvest sprouting resistance of wheat varieties from different ecological regions.].

The pre-harvest sprouting (PHS) resistance of 137 wheat varieties from different regions was evaluated and the relative germination index (RGI) was calculated. The relationships between PHS and grain quality traits, amylase activity and related gene expression level of these varieties were analyzed. The results showed that wheat varieties from the middle and lower reaches of Yangtze River Valley winter wheat region had the lowest RGI value and the highest ratio of resistant pre-harvest sprouting wheat varieties, followed by the varieties from the upper reach of Yangtze River Valley winter wheat region and from the Yellow and Huai River Valley.

Transcriptomic analysis of resistant and susceptible cabbage lines reveals differential expressions and candidate genes involved in cabbage early responses to black rot.

Cabbage ( var) is one of the most important cruciferous leafy vegetable crops and is widely cultivated all over the world. Its yield and quality are often affected by diseases such as cabbage black rot. 2R is a cabbage line that is newly resistant to black rot, which was created by radiation mutagenesis and backcross transfer.
