摘要

甘薯(Ipomoea batatas L.)易受根结线虫(RKN)Meloidogyne incognita的感染,导致这种全球重要块茎作物的产量显著下降。此前,转录组分析显示,易受 RKN 感染和抗 RKN 感染的甘薯栽培品种根部的基因表达存在差异,这为确定参与保护免受 RKN 感染的基因提供了可能性。此外,还发现了一些性状特异性基因和/或反应特异性基因,包括由节蛋白-26-样内在蛋白(NIP)基因编码的 RKN 感染反应性水汽蛋白。因此,本研究调查了 NIP 基因在易感甘薯和抗性甘薯栽培品种对 RKN 感染的防御反应中的作用。通过比较甘薯与其近缘种牵牛花的核苷酸序列,发现一组 NIP 基因可分为四个不同的直向同源组。这四个组包含几个独特的基因,这些基因在甘薯根中的表达在 RKN 感染后发生了变化。这些结果表明,NIP 基因可能在保护甘薯根系免受 RKN 感染方面发挥潜在作用。

Differential expression of sweetpotato nodulin 26-like intrinsic protein (NIP) genes in response to infection with the root knot nematode

Sweetpotato (Ipomoea batatas L.) is susceptible to infection by the root knot nematode (RKN) Meloidogyne incognita, which results in significant reductions in the yield of this important tuber crop worldwide. Previously, transcriptome analysis revealed differential gene expression between the roots of RKN-susceptible and -resistant sweetpotato cultivars after RKN infection, raising the possibility of identifying the genes involved in protection against RKN infection. A number of trait-specific and/or response-specific genes were also identified, including RKN infection-responsive aquaporin protein encoded by the nodulin-26-like intrinsic protein (NIP) gene. Therefore, in this study, we investigated the role of NIP genes in the defense response to RKN infection in susceptible and resistant sweetpotato cultivars. A comparison of the nucleotide sequences of sweetpotato with those of its closely related species, morning glory, revealed a group of NIP genes that could be categorized into four different ortholog groups. These four groups contained several unique genes that showed changes in expression in sweetpotato roots after RKN infection. These results indicate that NIP genes could have a potential role in protecting sweetpotato roots from RKN infection.

期刊介绍: Plant Biotechnology Reports publishes original, peer-reviewed articles dealing with all aspects of fundamental and applied research in the field of plant biotechnology, which includes molecular biology, genetics, biochemistry, cell and tissue culture, production of secondary metabolites, metabolic engineering, genomics, proteomics, and metabolomics. Plant Biotechnology Reports emphasizes studies on plants indigenous to the Asia-Pacific region and studies related to commercialization of plant biotechnology. Plant Biotechnology Reports does not exclude studies on lower plants including algae and cyanobacteria if studies are carried out within the aspects described above.
