Abstract

Rice is a major cereal crop and serves as staple food for a large part of the human population. Rice blast is a very important disease that attacks rice and is found in every region where rice is grown. Here we identified differentially expressed genes during different time intervals of the blast infection. Our results show that at 24 hpi almost half of the identified genes (174 of 224) are under expressed, then at 36 hpi only 26 genes out of 278 identified genes were down regulated. Then for 2nd, 4th and 6th day mostly differentially expressed genes remained up regulated. Also, the most significant gene ontology terms identified for these genes were diterpenoid metabolic process, diterpene phytoalexin metabolic process and phytoalexin metabolic process, isoprenoid metabolic process, terpenoid metabolic process and lipid metabolic process. This study has led to a more comprehensive data for understanding rice defense response.

水稻转录组学比较及稻瘟病感染靶基因的开发

大米是一种主要的谷类作物，是大部分人口的主食。稻瘟病是一种危害水稻的重要病害，在水稻生长的各个地区都有发生。在这里，我们确定了在不同时间间隔的胚感染差异表达的基因。我们的研究结果表明，在24 hpi时，几乎一半的鉴定基因(224个中的174个)是低表达的，而在36 hpi时，278个鉴定基因中只有26个基因是下调的。然后在第2、4和6天，大多数差异表达基因保持上调。这些基因最重要的基因本体术语是二萜代谢过程、二萜植物抗菌素代谢过程和植物抗菌素代谢过程、类异戊二烯代谢过程、萜类代谢过程和脂类代谢过程。本研究为了解水稻防御反应提供了更全面的数据。

期刊介绍： Agri Gene publishes papers that focus on the regulation, expression, function and evolution of genes in crop plants, farm animals, and agriculturally important insects and microorganisms. Agri Gene strives to be a diverse journal and topics in multiple fields will be considered for publication so long as their main focus is on agriculturally important organisms (plants, animals, insects, or microorganisms). Although not limited to the following, some examples of potential topics include: Gene discovery and characterization. Genetic markers to guide traditional breeding. Genetic effects of transposable elements. Evolutionary genetics, molecular evolution, population genetics, and phylogenetics. Profiling of gene expression and genetic variation. Biotechnology and crop or livestock improvement. Genetic improvement of biological control microorganisms. Genetic control of secondary metabolic pathways and metabolic enzymes of crop pathogens. Transcription analysis of beneficial or pest insect developmental stages Agri Gene encourages submission of novel manuscripts that present a reasonable level of analysis, functional relevance and/or mechanistic insight. Agri Gene also welcomes papers that have predominantly a descriptive component but improve the essential basis of knowledge for subsequent functional studies, or which provide important confirmation of recently published discoveries provided that the information is new.
