Identification of Candidate Gene <i>SalT</i> and Designing Markers Involving in Salt Tolerance of Vietnamese Rice Landraces

International Letters of Natural Sciences (2017)

Khuất Hữu Trung Nguyen Truong Khoa Nguyen Thuy Diep Trần Thị Thu Thủy Dang Thi Thanh Ha

Rice ( Oryza sativa L.) is a principle crop with great economic importance in Vietnam, providing daily food for over 90 million people in this country. However, a large rice growing areas and rice production are being seriously affected by the threats of devastation from climate change. The need to develop salinity tolerance rice varieties to cope with adverse climate change is very imperative. In this study, based on the genome sequence databases of 36 Vietnamese rice landraces, we have identified 9 Vietnamese rice landraces carrying nine SalT candidate gene with the sequence similarity to O. sativa SalT (the published GenBank: Z25811.1) which have shown salinity tolerance are: Te Nuong, Khau mac buoc, Chan thom, Khau giang, Tan ngan, Nang thom cho dao, OM5629, Hom rau and Thom Lai). Amongst them, 4 rice landraces including Nang thom cho dao, OM5629, Hom rau and Thom lai have shown 2 fragments of deletion with 6 and 7 nucleotides which were most identical to the reference SalT gene. Two primers has been successfully designed to identify the SalT candidate gene in Vietnamese rice landraces. This study provides useful information of salinity tolerance of some Vietnamese rice landraces for breeding programs.

Objective: The study aimed to evaluate the effectiveness of the Clinical Decision Support System (CDSS) in dosage adjustment for inpatients with renal impairment at Thai Binh University Hospital. Subjects and methods: Medical records of inpatients treated at Thai Binh University Hospital were reviewed during the periods from 01/01/2022 to 30/11/2022 and from 01/12/2022 to 15/03/2023. Study design: a cross-sectional descriptive study. Results: Before the integration of CDSS, among 300 medical records, dose adjustment was required in 81.7% of medical records, which included 64.5% inappropriate dosage modification. There were 406 prescriptions requiring dose adjustment, accounting for 31.5% of the total prescriptions, and 52.7% of the total prescriptions had inappropriate dose adjustment. After the integration of CDSS, 320 alerts were recorded for 55 patients between December 1st, 2022, and March 15th, 2023. The alert cancellation proportion was 2.8%. Among the alerts that were overridden, 55.6% involved clinical pharmacist consultations. The combination of CDSS and clinical pharmacist consultations reduced the proportion of prescriptions and medical records having inappropriate dosage adjustments to 10.6% and 16.4%, respectively. Conclusion: CDSS had positive impacts on dosage adjustments in inpatients with renal insufficiency at Thai Binh Medical University Hospital.

Mai Như Phương Trần Thị Thu Thủy

Mục đích của nghiên cứu này nhằm xác định khả năng ức chế vi khuẩn Xanthomonas oryzae pv. oryzae (Xoo) trên đĩa petri và ảnh hưởng đến sự nảy mầm của hạt lúa bằng dịch trích từ cỏ cứt heo (Ageratum conyzoides L.). Phương pháp kháng sinh đồ được xác định bằng khuếch tán dịch trích vào môi trường Wakimoto chứa vi khuẩn Xoo với 5 lần lặp lại. Kết quả cho thấy, khả năng kháng khuẩn của các nghiệm thức không có sự khác biệt so với nghiệm thức đối chứng (nước vô trùng) với vùng ức chế từ 0 – 0,75 mm sau 96 giờ sau khi cấy. Do đó, dịch trích từ A. conyzoides L. ở các nồng độ khác nhau không có tác dụng kháng khuẩn trực tiếp đối với Xoo. Thử nghiệm ảnh hưởng đến sự nảy mầm của hạt lúa bằng dịch trích từ A. conyzoides L. cho thấy nghiệm thức dịch trích có chiều dài diệp tiêu tương đương nghiệm thức đối chứng (nước vô trùng) ở các thời điểm 48, 72 và 96 giờ sau xử lý. Về độ dài của rễ, tất cả các nghiệm thức dịch trích cũng giống như nghiệm thức đối chứng ở thời điểm 72 và 96 giờ sau xử lý. Vì vậy, có thể kết luận rằng, việc ngâm dịch trích A. conyzoides L. ở các nồng độ khác nhau không ảnh hưởng đến sự nảy mầm của hạt lúa. Ngoài ra, nồng độ cỏ cứt heo 2% với biện pháp ngâm hạt hay phun kết hợp giai đoạn 25 ngày sau khi gieo và 35 ngày sau khi gieo thể hiện giảm chiều dài vết bệnh ở thời điểm 7 ngày sau khi lây bệnh.

Isolation Process and Compound Identification of Agarwood Essential Oils from Aquilaria crassna Cultivated at Three Different Locations in Vietnam

Processes (2019)

Đinh Thị Thu Thủy Trần Thị Tuyến Trần Thị Thu Thủy Phạm Thị Hồng Minh Trần Quốc Toàn

Agarwood and agarwood essential oils are commodities with great commercial value. In Vietnam, the agarwood industry has been growing, with more than 10,000 ha of forest land reserved for the cultivation of Aquilaria crassna, an agarwood-producing tree. The aim of this study was to present a hydrodistillation process to recover agarwood essential oil and to compare chemical compositions of agarwood samples harvested from various locations in Vietnam. Three agarwood samples representing products from A. crassna trees cultivated in the provinces of Bac Giang and Khanh Hoa, and on the Phu Quoc island (Kien Giang province) of Vietnam were subjected to hydrodistillation, resulting in essential oil yields of 0.32%, 0.27%, and 0.25% (w/w), respectively. Using GC–MS analysis, a total of 44 volatile compounds were identified in the obtained oils. Most of the constituents were oxygenated sesquiterpenes and had been previously found in other agarwood oil samples. Notable compounds of other chemical classes were aromatics and fatty acids. The three oil samples showed a common volatile profile, which is characterized by the dominance of eremophilane, agarofurans, and eudesmane sesquiterpenes, while vetispirane and guaiane sesquiterpenes were found in smaller quantities. Desired compounds, such as neopetasane (7.47–8.29%), dihydrokaranone (2.63–3.59%), β-agarofuran (3.04–6.18%), and agarospirol (2.98–3.42%), were present in substantial quantities, suggesting that the essential oils could be commercialized as fragrant materials of high value.

Resequencing of 672 Native Rice Accessions to Explore Genetic Diversity and Trait Associations in Vietnam

Rice (2021)

Janet Higgins Bruno Santos Tran Dang Khanh Khuất Hữu Trung Tran Duy Duong

Abstract Background Vietnam possesses a vast diversity of rice landraces due to its geographical situation, latitudinal range, and a variety of ecosystems. This genetic diversity constitutes a highly valuable resource at a time when the highest rice production areas in the low-lying Mekong and Red River Deltas are enduring increasing threats from climate changes, particularly in rainfall and temperature patterns. Results We analysed 672 Vietnamese rice genomes, 616 newly sequenced, that encompass the range of rice varieties grown in the diverse ecosystems found throughout Vietnam. We described four Japonica and five Indica subpopulations within Vietnam likely adapted to the region of origin. We compared the population structure and genetic diversity of these Vietnamese rice genomes to the 3000 genomes of Asian cultivated rice. The named Indica-5 (I5) subpopulation was expanded in Vietnam and contained lowland Indica accessions, which had very low shared ancestry with accessions from any other subpopulation and were previously overlooked as admixtures. We scored phenotypic measurements for nineteen traits and identified 453 unique genotype-phenotype significant associations comprising twenty-one QTLs (quantitative trait loci). The strongest associations were observed for grain size traits, while weaker associations were observed for a range of characteristics, including panicle length, heading date and leaf width. Conclusions We showed how the rice diversity within Vietnam relates to the wider Asian rice diversity by using a number of approaches to provide a clear picture of the novel diversity present within Vietnam, mainly around the Indica-5 subpopulation. Our results highlight differences in genome composition and trait associations among traditional Vietnamese rice accessions, which are likely the product of adaption to multiple environmental conditions and regional preferences in a very diverse country. Our results highlighted traits and their associated genomic regions that are a potential source of novel loci and alleles to breed a new generation of low input sustainable and climate resilient rice.

Occurrence of Melibiose‐Containing Glycosphingolipids in a Sample of a Sponge‐Coral Association (Desmapsamma anchorata/Carijoa riisei)

Chemistry & Biodiversity (2018)

Еlena А. Santalova В. А. Денисенко Pavel S. Dmitrenok Dinh T. Ha Nguyễn Anh Hưng

In our research on biologically active compounds from Vietnamese marine invertebrates, rare melibiose-containing glycosphingolipids were found in a sample of a sponge-coral association (Desmapsamma anchorata/Carijoa riisei). Melibiosylceramides were analyzed as constituents of some multi-component RP-HPLC fractions, and the structures of 14 new (1b, 3b, 4a-4c, 6a-6c, 8b, 9a, 9b, 10b, 11a, 11b) and five known (2b, 5a-5c, 7b) natural compounds were elucidated using NMR, mass spectrometry, optical rotation, and chemical transformations. These α-d-Galp-(1→6)-β-d-Glcp-(1 ↔ 1)-ceramides (presumably sponge-derived compounds) were shown to contain phytosphingosine-type n-t17:0 (1), (6E)-n-t17:1 (2), i-t17:0 (3), n-t18:0 (4), (6E)-n-t18:1 (5), i-t18:0 (6), (6E)-i-t18:1 (7), i-t19:0 (8), (6E)-i-t19:1 (9), ai-t19:0 (10), and (6E)-ai-t19:1 (11) backbones N-acylated with saturated straight-chain (2R)-2-hydroxy C21 (a), C22 (b), and C23 (c) acids. Characteristic trends in the fragmentations of the terminal parts of tetraacetylated normal-chain and iso- and anteiso-branched sphingoid bases were observed using GC/MS. The total sum of melibiosylceramides and compound 5b caused a reduction in colony formation of human melanoma cells.

A novel finite element model in nonlocal transient analysis of viscoelastic functionally graded porous nanoplates resting on viscoelastic medium

Mathematical Methods in the Applied Sciences (2023)

Nguyen Thi Giang Trần Thị Thu Thủy Nguyen Thi Hai Van

The transient analysis of viscoelastic functionally graded porous (FGP) nanoplate resting on the viscoelastic medium using the finite element method (FEM) is studied in this work. The nanoplate is made from a material that varies in thickness and has mechanical qualities that change depending on the porosity. The whole of the mechanical system rests on a Pasternak medium, which is modeled in accordance with a Kelvin–Voigt viscoelastic model. The general plate motion balance equations are developed by the application of the higher‐order shear plate theory (HSDT) with a new inverse hyperbolic function, the nonlocal hypothesis, and Hamilton's principle. In order to develop a four‐node quadrilateral element, Lagrangian and Hermitian interpolation functions are used. These functions are employed to define the main variables that correspond to the in‐plane displacements and the transverse displacements, respectively. The direct integration method developed by Newmark is used to calculate the dynamic responses of the plate. The outcomes that were anticipated by the essay have been confirmed by reputable sources. The dynamic response characteristics of a viscoelastic FGP nanoplates that is placed on a viscoelastic medium are explored, and a number of factors that influence these features are discovered and explained.
