Genome-wide Identification of U-box Genes and Protein Ubiquitination under PEG-induced Drought Stress in Potato.

Physiol Plant 2021 Jun 10. Epub 2021 Jun 10.

Gansu Provincial Key Laboratory of Aridland Crop Science, Gansu Agricultural University, Lanzhou, People's Republic of China.

Protein ubiquitination is one of the most important post-translational modifications in eukaryotic cells, and it is involved in a variety of biological processes, including abiotic stress response. The ubiquitination modification is highly specific, which depends on the accurate recognition of substrate proteins by ubiquitin ligase. Plant U-box (PUB) proteins are a class of ubiquitin ligases, multiple members of which have shown to participate in water-deficit stress in Arabidopsis and rice. Read More

Gene Expression Profile of the Human Colorectal Carcinoma LoVo Cells Treated With Sporamin and Thapsigargin.

Front Oncol 2021 25;11:621462. Epub 2021 May 25.

School of Public Health, Capital Medical University (CMU), Beijing, China.

Sporamin, a proteinase inhibitor isolated from the sweet potato (), has shown promising anticancer effect against colorectal cancer (CRC) and but its mechanisms of action are poorly understood. In the present study, high throughput RNA sequencing (RNA-seq) technology was applied to explore the transcriptomic changes induced by sporamin in the presence of thapsigargin (TG), a non-12-O-tetradecanolphorbol-13-acetate type cancer promoter, in the LoVo human CRC cells. Cellular total RNA was extracted from the cells after they were treated with vehicle (CTL), 1 μM of thapsigargin (TG), or 1 μM of TG plus 30 μM of sporamin (TGSP) for 24 h. Read More

Rheological behaviors and physicochemical changes of doughs reconstituted from potato starch with different sizes and gluten.

Food Res Int 2021 Jul 11;145:110397. Epub 2021 May 11.

Institute of Food Science and Technology, Chinese Academy of Agricultural Sciences, Key Laboratory of Agro-Products Processing, Ministry of Agriculture and Rural Affairs, Beijing 100193, PR China. Electronic address:

The effects of different sizes of potato starch on the rheological and physiochemical properties of model doughs were investigated. Compared with those of model dough prepared from original starch, the strengths of model doughs prepared from fractionated starch were higher, which indicates that fractionated starch can positively influence the properties of doughs. Additionally, the model dough prepared using large size starch granules had higher storage modulus (G'), loss modulus (G''), and composite modulus (|G*|) values compared to those of other types of dough; it also had the highest elasticity, viscosity, and strength.

Department of Earth and Planetary Sciences, Weizmann Institute of Science, Rehovot, Israel.

Extensive use of nanomaterials in agriculture will inevitably lead to their release to the environment in significant loads. Thus, understanding the fate of nanoparticles in the soil-plant environment, and potential presence and consequent implication of nanoparticles in food and feed products, is required. We study plant uptake of gold nanoparticles from soil, and their distribution, translocation and speciation (in terms of particle size change and release of ionic Au) in the different plant tissues of four important crops (potato, radish, carrot and lettuce).

Research Institute for Bioscience Products & Fine Chemicals, Ajinomoto Co., Inc., 1-1, Suzuki-cho, Kawasaki-ku, Kawasaki, 210-8681, Japan.

RNA-based pesticides exert their function by suppressing the expression of an essential gene in the target pest through RNA interference caused by double-stranded RNA (dsRNA). Here, we selected target genes for growth suppression of the solanaceous crop pests ladybird beetle (Henosepilachna vigintioctopunctata) and Colorado potato beetle (Leptinotarsa decemlineata)-the death-associated inhibitor of apoptosis protein 1 gene (diap1), and an orthologous gene of the COPI coatomer protein complex (copI), respectively. We constructed a cost-competitive overproduction system for dsRNA using Corynebacterium glutamicum as a host bacterium. Read More

ACS Omega 2021 Jun 19;6(21):13847-13857. Epub 2021 May 19.

Department of Chemical Engineering (ENTEG), University of Groningen, Nijenborgh 4, 9747 AG Groningen, The Netherlands.

Oxidized starch can be efficiently prepared using HO as an oxidant and iron(III) tetrasulfophthalocyanine (FePcS) as a catalyst, with properties in the same range as those for commercial oxidized starches prepared using NaOCl. Herein, we performed an in-depth study on the oxidation of potato starch focusing on the mode of operation of this green catalytic system and its fate as the reaction progresses. At optimum batch reaction conditions (HO/FePcS molar ratio of 6000, 50 °C, and pH 10), a high product yield (91 wt %) was obtained with substantial degrees of substitution (DS of 1. Read More

Effects of preceding crops and nitrogen fertilizer on the productivity and quality of malting barley in tropical environment.

Heliyon 2021 May 24;7(5):e07093. Epub 2021 May 24.

Kulumsa Agricultural Research Center, Ethiopian Institute of Agricultural Research, P.O.Box 489, Kulumsa, Ethiopia.

The growing demand for malt has generated interest for improving productivity through sustainable means such as cropping sequences with malting barley along with optimum nitrogen (N) fertilization. Cropping sequence has many benefits for optimum yield and quality, but knowledge of rotational effects of preceding crops on malting barley is still limited. Thus, this study was conducted to determine the effects of legume and non-legume preceding crops, and N fertilization on productivity and quality of malting barley grown the following year in two locations in the southeastern highland of Ethiopia.
