Radix Isatidis (Isatis indigotica Fort.) is one of the most important traditional Chinese medicine plants. However, there no suitable herbicide used for weed control in field during postemergence stage. To explore safety sulfonylurea nicosulfuron on seedlings and photosynthetic physiological response plant to herbicide, biological mass, leaf area, pigment content, rate, chlorophyll fluorescence characteristics, P700 parameters were analyzed 10 d after treatment at 5th stage this greenhouse...

Foxtail millet (Setaria italica L.) is cultivated around the world for human and animal consumption. There no suitable herbicide available weed control in foxtail fields during post-emergence stage. In this study, we investigated effect safety of tribenuron-methyl (TBM) on terms grain yield quality using a split-plot field design. Field experiments were conducted two varieties 2013 2014, i.e., high-yielding hybrid Zhangzagu 10 high-quality conventional Jingu 21. TBM treatments at 11.25 to 90...

YABBY genes are plant-specific transcription factors (TF) that function in plant growth and development. We investigated the functions of plants' stress tolerance by analyzing foxtail millet (Setaria italica) studying their on responses to different stresses. Eight were identified five chromosomes, which showed strong relationships with other monocot species. Phylogenetical SiYABs classified into four clades: FIL/YAB3, YAB2, INO, CRC. No member was YAB5 clade. Four conserved motifs...

Breeding of male-sterile lines has become the mainstream for heterosis utilization in foxtail millet, but genetic basis most used hybrid is still an area to be elucidated. In this study, a highly line Gao146A was investigated. Genetic analysis indicated that phenotype controlled by single recessive gene gene. Using F2 population derived from cross Gao146A/K103, one controlling male-sterility, tentatively named as ms1, which linked SSR marker b234 with distance 16.7 cM, mapped on chromosome...
