Gel-to-Solution Transition of Sulfhydryl Self-Assembled Peptide Hydrogels Undergoing Oxidative Modulation.

The design of self-assembling biomaterials needs to take into consideration the timing and location of the self-assembly process. In recent decades, the principal strategy has been to control the peptide self-assembly under specific conditions to enable its functional performance. However, few studies have explored the responsive elimination of functional self-assembled peptide hydrogels after their function has been performed.

Thioethers as Dichotomous Electrophiles for Site-Selective Silylation via C-S Bond Cleavage.

The development of aryl alkyl sulfides as dichotomous electrophiles for site-selective silylation via C-S bond cleavage has been achieved. Iron-catalyzed selective cleavage of C(aryl)-S bonds can occur in the presence of β-diketimine ligands, and the cleavage of C(alkyl)-S bonds can be achieved by t-BuONa without the use of transition metals, resulting in the corresponding silylated products in moderate to excellent yields. Mechanistic studies suggest that Fe-Si species may undergo metathesis reactions during the cleavage of C(aryl)-S bonds, while silyl radicals are involved during the cleavage of C(alkyl)-S bonds.

Transcriptome analysis and identification of genes associated with leaf crude protein content in foxtail millet [ (L.) P. Beauv.].

Spruce spider mite is a primary insect pest of Chinese chestnut in China and seriously influences its yield and quality. However, the current management against this mite is costly and poorly effective. In previous research, we bred several foxtail millet materials for interplanting with chestnut tree, and found that they had high levels of crude protein (CP) in leaves and attracted spruce spider mite to feed on the leaves, thereby reducing chestnut damage.

Transcriptome analysis and mining of genes related to shade tolerance in foxtail millet ( (L.) P. Beauv.).

A stereo interplanting system with foxtail millet beneath chestnut trees is an effective planting method to raise the utilization of land in chestnut orchards, increase yields and improve quality of chestnut nuts. Consequently, exploration of genes involved in shade tolerance response in foxtail millet and breeding shade-tolerant varieties have become urgent issues. In this study, RNA-seq of leaf samples from two shade-tolerant varieties and three shade-intolerant varieties of foxtail millet at the booting stage was performed.

Transcriptome analysis and characterization of genes associated to leaf tannin content in foxtail millet [Setaria italica (L.) P. Beauv.].

Background: Chinese chestnut is an economically important tree species whose yield and quality are seriously affected by red spider attack. Tannins is one of the most important class secondary metabolites in plants, and is closely associated with plant defense mechanisms against insect and herbivory. In our previous studies, it was revealed that several low-tannin foxtail millet varieties growing under the Chinese chestnut trees could attract red spiders to feed on their leaves and protect the chestnut trees from the infestation of red spiders, meanwhile, the growth and yield of foxtail millet plants themselves were not greatly affected.
