Transcription activator-like effectors（TALEs） are delivered by a type III secretion system（T3 SS） of Xanthomonas into plant nuclei to directly bind specific DNA sequences（TAL effector-binding elements, EBEs） on either strand of host target genes with an unique modular DNA-binding domain and to bidirectionally drive host gene transcription. The target genes in plants consist of host susceptibility（S） genes promoting disease（ETS） and resistance（R） genes triggering defense（ETI）. Here we generally summarized the discovery of TALEs in Xanthomonas species, their functions in bacterial pathogenicity in plants and their target genes in different host plants, and then focused on the newly revealed modes of protein action in triggering or suppressing plant defense.展开更多

The heterozygous populations and isogenic lines with homocaryotic alloplasmic genes were obtained by crossing and reciprocal crossing of cytoplasmic herbicide resistant plants with susceptive plants of foxtail millet. The characters of F1, F2, backcross and composite cross groups, and the growth and development of isogenic lines were compared. The cytoplasmic herbicide resistant gene slowed the development of seedling, delayed heading, and shortened the milking stage in the foxtail millet plant. Yield capacity and main agronomic characters were all affected by the cytoplasmic herbicide resistant gene in most of the backcross, composite cross, and F2 populations. However, there was stronger hybrid vigor in F1. The backcrosses, composite crosses, and F2 populations were widely separated and some of them had good characters similar to those of susceptive groups. The plant characters and development of foxtail millet were negatively affected by the cytoplasmic herbicide resistant gene. The authors proposed a method of using hybrid vigor to obtain high yield and avoid the negative effects of herbicide resistance cytoplasm in plant growth. The expected results could be obtained by selecting individuals in separate populations of fast developed seedlings, well-developed roots, and with capacities of early heading and fast milking. Guided by the principal mentioned above, many high yield lines and hybrid crosses of foxtail millet with herbicide resistant cytoplasm were obtained.展开更多
