Abstract

Rice blast, caused by the fungus Pyricularia oryzae L., is considered one of the main threats to world rice production. The development of resistant cultivars is one of the best and sustainable control alternatives. Plant breeding efforts have been accelerated by genetic mapping (linkage and associative) and marker assisted selection. On the other hand, genomic editing techniques, such as meganucleases (MNs), Zinc-finger nucleases (ZFNs), Transcription Activator–like Effector Nucleases (TALENs) and Clustered Regularly Interspaced Short Palindrome Repeats/CRISPR-associated protein 9 (CRISPR/Cas9), can be used to promote specific genetic modifications. Likewise, transgenics can also be used to manipulate specific genes. In this sense, this work aims to characterize rice blast and elucidate available biotechnological alternatives to accelerate the development of improved rice cultivars resistant to rice blast.

稻瘟病:提高遗传抗性的策略与挑战

稻瘟病是由稻瘟病真菌稻瘟病引起的，被认为是世界水稻生产的主要威胁之一。抗性品种的开发是最好的和可持续的防治选择之一。遗传作图(连锁和关联)和标记辅助选择加速了植物育种工作。另一方面，基因组编辑技术，如巨核酶(MNs)、锌指核酸酶(ZFNs)、转录激活物样效应物核酸酶(TALENs)和聚集规律间隔短回语重复序列/CRISPR相关蛋白9 (CRISPR/Cas9)，可用于促进特定的遗传修饰。同样，转基因也可以用来操纵特定的基因。从这个意义上说，本工作旨在研究稻瘟病的特性，并阐明可用的生物技术替代方案，以加速稻瘟病抗性改良水稻品种的开发。

期刊介绍： The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL. It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
