Cloning of a peroxidase gene from cassava with potential as a molecular marker for resistance to bacterial blight BABT
Pereira,Luiz Filipe; Goodwin,Paul H.; Erickson,Larry.
Cassava bacterial blight (CBB), caused by Xanthomonas axonopodis pv. manihotis, is considered one of the most important bacterial diseases of cassava (Manihot esculenta Crantz). In order to characterize the cassava genes involved in resistance to this disease, a genomic clone of a cationic peroxidase gene, MEPX1, was isolated by PCR from cassava cultivar MCOL 22. The DNA sequence of MEPX1 showed high homology with other plant peroxidase genes and contained a large intron typical of peroxidase genes. The predicted translation product showed a heme-ligand motif, also a characteristic of peroxidases, as well as phosphorylation, myristoylation and glycosylation sites. The amino acid sequence had 75 % homology with two Arabidopsis thaliana peroxidases. A...

Establishment of an in vitro system for studies on the induced resistance of cotton to Xanthomonas campestris pv. malvacearum PAB
KOBAYASHI,ADILSON KENJI; VIEIRA,LUIZ GONZAGA ESTEVES.
An in vitro system for studying the resistance response of cotton (Gossypium hirsutum L.) to Xanthomonas campestris pv. malvacearum was investigated. Cell suspension cultures, established from hypocotyl-derived callus of cotton cultivar 101-102B, were treated with bacterial extracellular polysaccharides (EPS) extracted from the incompatible race 18 of X. campestris pv. malvacearum. EPS at 600 mug/mL caused pronounced darkening of the suspension cultures, as indicative of cell death, 48 hours after incubation. Protein electrophoresis analysis of the time course of EPS-treated cells showed differential accumulation of several protein bands after 12-24 hours. The time course of protein accumulation and cell death was consistent with an elicitor-mediated...

Frequência e severidade de doenças da soja nos Estados do Rio Grande do Sul e Santa Catarina. Repositório Alice
LEHMAN, P. S.; MACHADO, C. C.; TARRAGO, M. T..
Nos Estados do Rio Grande do Sul e Santa Catarina foi observado um total de 104 lavouras durante um ciclo completo, em quatro epocas diferentes, onde se notou doenca em 100% das lavouras. As doencas que ocorreram mais frequentemente foram: crestamento bacteriano (Pseudomonas glycinea Coerper), mancha marrom (Septoria glycines Hemmi) e antracnose (Colletotrichum dematium var. truncata (Schw) Von Arx.), observadas respectivamente em 73, 65 e 57% das lavouras. A mancha-em-reboleira, causada principalmente por Rhizoctonia solani Khun, e frequentemente interagido com Fusarium oxysporum, tambem causou perdas severas nas regioes de producao mais importantes, especialmente na regiao do planalto. O mildio [Peronospora manshurica (Naoum) Syd.], detectado pela...

Green propolis ethanolic extract in bean plant protection against bacterial diseases Ciência Rural
Jaski,Jonas Marcelo; Telaxka,Fabio Junior; Moura,Gabriela Silva; Franzener,Gilmar.
ABSTRACT: The aim of this study was to evaluate the ethanolic extract of green propolis (EEP) in the protection of common bean plants against two main bacterial cultures, bacterial blight (Xanthomonas axonopodis pv. phaseoli) and wildfire (Pseudomonas syringae pv. tabaci). Experiments on antimicrobial activity were performed, inducing phytoalexins, defense-related enzymes, and disease severity, under concentrations of 0, 0.5, 1.0, 2.5, and 5.0%. The EEP presented antimicrobial activity on both phytobacteria, causing a decrease in their development. It has also promoted a linear accumulation of phaseolin in bean hypocotyls according to the EEP concentration used. There was a reduction in the lesion area, which was caused by bacterial blight on bean leaves...

Marker-assited screening of cotton cultivars for bacterial blight resistance gene. Repositório Alice
FAUSTINE, C.; HOFFMANN, L. V.; LUKONGE, E.; TIBAZARWA, F. I..
Bacterial blight or leaf blight is a common disease of cotton in almost all cotton growing countries, including Tanzania. Bacterial blight is caused by infection of plants with the bacteria (Xanthomonas axonopodis pv. malvacearum) and the use of resistant cultivars is the most effective long-term strategy to manage the disease. The strategy starts with identification of resistant individuals, which can be identified either phenotypically by inoculation or by use of molecular markers linked to genes that confer resistance. The B12 gene is known to confer a high level of resistance to all Xanthomonas axonopodis pv. malvacearum races found in USA and Africa. Four Brazilian and three local cultivars were screened for the presence of SSR (CIR246) and SNP...

Study on the Effect of Different Urea Fertilizer Rates and Plant Populations on the Severity of Bacterial Blight (BB) of Rice JARTS
Myint, Si Si; Nyunt, Khin Maung; Ko, Hla Ko; Thein, Maung Maung.
To study the effect of different urea fertilizer rates and plant populations on disease severity of bacterial blight of rice and yield lasses related to disease, the experiments including three plant populations (110000, 150000, 190000) and five urea fertilizer rates (0,56 lb, 112 lb, 168 lb and 224 lb per acre) were conducted at Central Agriculture Research Institute farm in 1999 and 2000 rainy seasons. Manawthukha was used as a test variety that is susceptible to bacterial blight of rice. The disease severity could be increased by the application of urea. Although urea 112 lb per acre gave moderate disease severity than without urea, its yield is highest. The higher disease severity also showed the related effect of plant population of 150000 and above....

Bacterial blight (BB), caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the most serious diseases of rice in all major rice-growing areas of Thailand. The most effective approach to control BB is the use of resistant varieties which is economically feasible, an environmental-friendly control method and easy for farmers to handle. However, the selection pressure from the usage of resistant cultivars may result in mutation of the pathogen population to overcome the resistance genes. A feasible method to solve this problem is by pyramiding multiple resistance genes, which are board spectrum, into susceptible rice varieties. The aims of this research were to identify the effectiveness of board spectrum BB resistance genes and to better understand the...

The most effective approach to control BB is the use of resistant varieties. However, the selection pressure from the usage of resistant cultivars may result in mutation of the pathogen population to overcome the resistance genes. Therefore, using genetic resources conferring different resistance genes are more advantage in rice improvement. The aim of this research was to survey and screen BB resistance genes in Thai local rice varieties from the National Rice Seed Storage Laboratory for Genetic Resources to gain more genetic diversity for resistance. In this study, the Thai Local rice...

水稻抗白葉枯病基因表現蛋白質之多白胺酸重復(LRR)的分布及胺基酸組成 Taiwan Agricultural Research Institute

[[abstract]]目前已知多白胺酸重複 (leucine-rich repeat, LRR) 為生物體抗病基因蛋白質序列 上的特有序列,因此本研究針對水稻所有已定序之Xa基因,自NCBI (National Center for Biotechnology Information) 及KOME (Knowledge-based Oryza Molecular Biological Encyclopedia) 公共資料庫內擷取出它們已知的CDS (coding domain sequence) 與全 長cDNA 序列,將其轉譯的蛋白質序列利用Pfam 蛋白質家族資料庫尋找出各LRR 片段,發現僅在Xa1、Xa21 及Xa26 基因之表現蛋白質結構中發現LRR 存在。進而 利用生物資訊與統計方法,進行不同Xa 基因蛋白質之LRR 序列的分布及胺基酸組成 之比較分析。結果顯示,Xa1 之LRR 在蛋白質序列中鬆散分布於NB-ARC (nucleotidebinding adaptor shared by APAF-1, R proteins, and CED-4) 區域序列之後,而Xa21 及 Xa26 之LRR 則密集分布在NB-ARC 或P-kinase (protein-kinase) 區域序列之前。Xa1 的蛋白質序列中靠近NB-ARC 區域序列的前一、二個LRR 似乎較遠離其他LRR,但 Xa21 和Xa26 的蛋白質之LRR 區域結構並未有如此現象。三個Xa 基因表現蛋白質之 LRR 序列的胺基酸組成皆以親水性胺基酸為最多且其中以白胺酸 (leucine) 出現頻 率最高,其次為不帶電荷之絲胺酸 (serine)。Xa1 蛋白質之LRR 在某些胺基酸的出現 頻率相異於Xa21...
