Genome-wide Association Analysis Tracks Bacterial Leaf Blight Resistance Loci In Rice Diverse Germplasm
Rice - Tập 10 - Trang 1-17 - 2017
Christine Jade Dilla-Ermita, Erwin Tandayu, Venice Margarette Juanillas, Jeffrey Detras, Dennis Nicuh Lozada, Maria Stefanie Dwiyanti, Casiana Vera Cruz, Edwige Gaby Nkouaya Mbanjo, Edna Ardales, Maria Genaleen Diaz, Merlyn Mendioro, Michael J. Thomson, Tobias Kretzschmar
A range of resistance loci against different races of Xanthomonas oryzae pv. oryzae (Xoo), the pathogen causing bacterial blight (BB) disease of rice, have been discovered and characterized. Several have been deployed in modern varieties, however, due to rapid evolution of Xoo, a number have already become ineffective. The continuous “arms race” between Xoo and rice makes it imperative to discover...... hiện toàn bộ
Osa-miR162a fine-tunes rice resistance to Magnaporthe oryzae and Yield
Rice - Tập 13 - Trang 1-13 - 2020

MicroRNAs (miRNAs) play essential roles in rice immunity against Magnaporthe oryzae, the causative agent of rice blast disease. Here we demonstrate that Osa-miR162a fine-tunes rice immunity against M. oryzae and yield traits. Overexpression of Osa-miR162a enhances rice resistance to M. oryzae accompanying enhanced induction of defense-related genes and accumulation of hydrogen peroxide (H2O2). In ...... hiện toàn bộ
Transcriptome profiling of the spl5 mutant reveals that SPL5 has a negative role in the biosynthesis of serotonin for rice disease resistance
Rice - Tập 8 - Trang 1-10 - 2015
Bin Jin, Xinru Zhou, Baolin Jiang, Zhimin Gu, Pinghua Zhang, Qian Qian, Xifeng Chen, Bojun Ma
Rice mutant, spl5 (spotted leaf 5), has spontaneous hypersensitive-like lesions on its leaves and shows enhanced resistance to pathogens, indicating that SPL5 plays a role in programmed cell death (PCD) and disease resistance. To understand the molecular mechanism of SPL5 gene, we investigated the transcriptome profiles of the spl5 mutant leaves with few lesions (FL) and leaves with many lesions (...... hiện toàn bộ
Mapping quantitative trait loci responsible for resistance to Bakanae disease in rice
Rice - Tập 9 - Trang 1-10 - 2016
R. Abdul Fiyaz, Ashutosh K. Yadav, S. Gopala Krishnan, Ranjith K. Ellur, Bishnu M. Bashyal, Nitasha Grover, Prolay K. Bhowmick, M. Nagarajan, K. K. Vinod, Nagendra K. Singh, Kumble V. Prabhu, Ashok K. Singh
Bakanae or foot rot disease caused by Fusarium fujikuroi [teleomorph: Gibberella fujikuroi (Sawada) Ito] is emerging as a serious disease in rice. The disease causes both quantitative and qualitative losses to the grains under the field conditions. Breeding for resistance to Bakanae disease is a promising strategy to manage this emerging disease. In this study, we used a population of 168 F14 reco...... hiện toàn bộ
Natural Diversity in Stomatal Features of Cultivated and Wild Oryza Species
Rice - Tập 13 - Trang 1-20 - 2020

Stomata in rice control a number of physiological processes by regulating gas and water exchange between the atmosphere and plant tissues. The impact of the structural diversity of these micropores on its conductance level is an important area to explore before introducing stomatal traits into any breeding program in order to increase photosynthesis and crop yield. Therefore, an intensive measurem...... hiện toàn bộ
Identification of Novel QTL Conferring Sheath Blight Resistance in Two Weedy Rice Mapping Populations
Rice - Tập 13 - Trang 1-10 - 2020
David M. Goad, Yulin Jia, Andrew Gibbons, Yan Liu, David Gealy, Ana L. Caicedo, Kenneth M. Olsen
Rice sheath blight (ShB) disease, caused by the pathogenic fungus Rhizoctonia solani, causes significant yield losses globally. US weedy rice populations, which are de-domesticated forms of indica and aus cultivated rice, appear to be more resistant to ShB than local japonica cultivated rice. We mapped quantitative trait loci (QTL) associated with ShB resistance using two F8 recombinant inbred lin...... hiện toàn bộ
Cấu trúc quy định upstream của các gen lúa: Tóm tắt cơ sở cho phân tích so sánh quy định mạng lưới trên toàn bộ chi và khai thác alen Dịch bởi AI
Rice - Tập 8 - Trang 1-21 - 2015
Benildo G de los Reyes, Bijayalaxmi Mohanty, Song Joong Yun, Myoung-Ryoul Park, Dong-Yup Lee
Việc phân tích cấu trúc quy định upstream của các gen lúa và các protein điều tiết tương ứng của chúng là cốt lõi của sinh học mạng lưới và các ứng dụng của nó trong sinh học chức năng so sánh. Với các nguồn tài nguyên sinh học so sánh về gen trong chi Oryza đang phát triển nhanh chóng, việc thiết lập một chú thích genome tham chiếu xác định các yếu tố cis và các yếu tố trans-acting khác nhau, kết...... hiện toàn bộ

TAL Effectors with Avirulence Activity in African Strains of Xanthomonas oryzae pv. oryzae
Rice - Tập 15 - Trang 1-13 - 2022
Marlène Lachaux, Emilie Thomas, Adam J. Bogdanove, Boris Szurek, Mathilde Hutin
Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial leaf blight, a devastating disease of rice. Among the type-3 effectors secreted by Xoo to support pathogen virulence, the Transcription Activator-Like Effector (TALE) family plays a critical role. Some TALEs are major virulence factors that activate susceptibility (S) genes, overexpression of which contributes to disease development. Host incomp...... hiện toàn bộ
Mutations in the microRNA172 binding site of SUPERNUMERARY BRACT (SNB) suppress internode elongation in rice
Rice - Tập 12 - Trang 1-14 - 2019
Hyeonso Ji, Chang-deok Han, Gang-Seob Lee, Ki-Hong Jung, Do-Yu Kang, Jun Oh, Hyoja Oh, Kyeong-Seong Cheon, Song Lim Kim, Inchan Choi, Jeongho Baek, Kyung-Hwan Kim
Internode elongation is an important agronomic trait in rice that determines culm length, which is related to lodging, panicle exsertion, and biomass. sui4 (shortened uppermost internode 4) mutants show reduced internode length and a dwarf phenotype due to shortened internodes; the uppermost internode is particularly severely affected. The present study was performed to identify the molecular natu...... hiện toàn bộ
