Comprehensive characterization of nutritional components in sweetpotato (Ipomoea batatas [L]. Lam.) during long-term post-harvest storage.

To uncover the variation patterns of the nutritional components in sweetpotato storage roots during long-term storage comprehensively, the general nutrients, phytochemicals, and starch properties of nine sweetpotato varieties with different flesh colors were quantified and analyzed by chemical and physical techniques. During the storage, the starch content decreased firstly and then increased, with sugar content the opposite. The crude protein content and the total dietary fiber content both increased continuously.

Construction of high-density genetic map based on SLAF-seq and QTL analysis of major traits in sweetpotato [Ipomoea batatas (L.) Lam.].

Sweetpotato, Ipomoea batatas (L.) Lam., is an important worldwide crop used as feed, food, and fuel.

Resequencing of sweetpotato germplasm resources reveals key loci associated with multiple agronomic traits.

Sweetpotato is an important crop that exhibits hexaploidy and high heterozygosity, which limits gene mining for important agronomic traits. Here, 314 sweetpotato germplasm resources were deeply resequenced, and 4 599 509 SNPs and 846 654 InDels were generated, among which 196 124 SNPs were nonsynonymous and 9690 InDels were frameshifted. Based on the Indels, genome-wide marker primers were designed, and 3219 of 40 366 primer pairs were selected to construct the core InDel marker set.

Comparative Analysis of Salt Responsive MicroRNAs in Two Sweetpotato [ (L.) Lam.] Cultivars With Different Salt Stress Resistance.

Sweetpotato [ (L.) Lam.] is an important food, vegetable and economic crop, but its productivity is remarkably affected by soil salinity.

Synthesis and Characterization of Flower-like Carbon-encapsulated Fe-C Nanoparticles for Application as Adsorbing Material.

Carbon-encapsulated Fe-C (Fe-C@C) nanoparticles with a divergently flower-like morphology were successfully synthesized for application as an adsorbing material by using freeze-drying and chemical vapor deposition (CVD) methods. The Fe metallic source was first loaded onto a sodium chloride (NaCl) supporter via freeze-drying to obtain the Fe/NaCl composite powder. Then, Fe-C@C nanoparticles were synthesized in the temperature range of 300⁻450 °C via CVD of acetylene in the Fe/NaCl composite powder using Fe nanoparticles as catalysts and NaCl as supporters.

Identification and diversity of functional centromere satellites in the wild rice species Oryza brachyantha.

The centromere is a key chromosomal component for sister chromatid cohesion and is the site for kinetochore assembly and spindle fiber attachment, allowing each sister chromatid to faithfully segregate to each daughter cell during cell division. It is not clear what types of sequences act as functional centromeres and how centromere sequences are organized in Oryza brachyantha, an FF genome species. In this study, we found that the three classes of centromere-specific CentO-F satellites (CentO-F1, CentO-F2, and CentOF3) in O.

(4-Hydroxy-phen-yl)methanaminium 2-(4-sulfanylphen-yl)acetate.

In the title mol-ecular salt, C(7)H(10)NO(+)·C(8)H(7)O(2)S(-), the crystal structure is stabilized by inter-molecular N-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds.

Diaqua-bis[2-(4-bromo-phen-yl)acetato]bis-(N,N-dimethyl-pyridin-4-amine)copper(II).

In the title compound, [Cu(C(8)H(6)BrO(2))(2)(C(7)H(10)N(2))(2)(H(2)O)(2)], the Cu(II) atom (site symmetry ) adopts a Jahn-Teller-distorted trans-CuN(2)O(4) octa-hedral coordination, with the aqua O atoms in axially extended sites. An intra-molecular O-H⋯O hydrogen bond helps to establish the conformation and an inter-molecular O-H⋯O hydrogen bond is seen in the crystal packing.
