Awn is one of important traits during rice domestication. To understand the development of rice awn and the roles it played in rice domestication, we preliminary mapped a major QTL An-3 for awn development using chromosome segment substitution line CSSL138 developed by introgressed genomic fragments of long-awned Guangxi common wild rice (GXCWR, Oryza rufipogon Griff.) into genetic background of short-awned indica cultivar 93–11. An-3 was then fine mapped to a 7-kb region of chromosome 8. An epidermal patterning factor-like protein gene was identified as the single candidate gene corresponding to this QTL. An-3 was showed to be an allele of RAE2 and GAD1, and negatively regulated 1000-grains weight, grain length, and length–width ratio. Comparing with the coding sequences of An-3 from CSSL138, a 2- and 4-bp frameshift deletions in the second exon were identified in 93–11 and Nipponbare, respectively. Taken together, our results provide valuable natural variation in the alleles of An-3 between common wild rice and cultivated rice, which will be helpful in clarifying the mechanism of awn development and promoting the application of an-3 in genetic improvement of rice yield traits.

In this paper, thermo-sensitive polyelectrolyte complex nanoparticles assembled from chitosan-graftpoly(N-isopropylacrylamide) (CS-g-PNIPAM) and sodium alginate-graft-poly(N-isopropylacrylamide) (SA-g-PNIPAM)were prepared for entrapment and release of 5-fluorouracil (5-FU). The morphology and size of the nanoparticles wereobserved by transmission electron microscopy (TEM) and dynamic light scattering (DLS). The polyelectrolyte complexnanoparticles showed a narrow size distribution. The hydrogen bonding interactions between nanoparticles and5-FU, which was determined by fourier-transformed infrared spectroscopy (FTIR), increased drug loading. Glutaraldehyde,as a cross-linking agent, reinforced the nanoparticle structure and decreased the burst drug release. Whenchanging temperature, pH, or ionic strength, a sustained and controlled drug release was observed. The novel complexnanoparticles with environmentally sensitive properties are expected to be useful in the field of intelligent drugdelivery system.

Amino-modified Mg-MOF-74: Synthesis, characterization and CO₂ adsorption performance
Xiaoying Lin,Weipeng Zeng,Minyi Liu,Qinhua Zhong,Ting Su,Linzhu Gong,Yamin Liu 대한환경공학회 2023 Environmental Engineering Research Vol.28 No.1
Based on the solvothermal method to synthesize Mg-MOF-74, the amino-functionalized Mg-MOF-nNH₂ was prepared through addition of amino-containing ligands. Physicochemical properties of Mg-MOF-nNH₂ materials were well characterized by Powder X-ray diffraction (PXRD), Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), N₂ adsorption/desorption isotherms (BET). The adsorption properties of the resulting materials were studied for CO₂. In all the samples, the micropore volume of Mg-MOF-1/8NH₂ was 0.46 ㎤ g<SUP>−1</SUP> and the specific surface area was 924.19㎡ g<SUP>−1</SUP>, the highest CO₂ saturated adsorption capacity was 3.9 mmol g<SUP>−1</SUP>, and the dynamic adsorption capacity was 1.27 mmol g<SUP>−1</SUP>. The adsorption processes agreed well with the Langmuir isotherm and Avrami model.
