Potato virus Y induced changes in the gene expression of potato (Solanum tuberosum L.)

Quantitative Gene Expression of Peroxidase, Polyphenoloxidase and Catalase as Molecular Markers for Resistance against <i>Ralstonia solanacearum</i>

“…It is thought that this allows H 2 O 2 to accumulate, resulting in antimicrobial activity through strengthening of the plant cell wall, activation of defense genes, hypersensitive cell death and a subsequent halt to pathogen infection [41]. In contrast, in susceptible hosts increases in host catalase activity have been observed by Havelda & Maule, [42] Kuzniak & Sklodowska, [43] and Pompe-Novaka et al, [44], exogenously applied catalase can result in decreased hypersensitive cell death [45] and increased penetration by pathogens of normally resistant hosts (Borden & Higgins, [46] and Abel et al, [47].…”

Association of the transcriptional response of soybean plants with soybean mosaic virus systemic infection

“…Transcripts encoding auxin-repressed protein were downregulated significantly in potato plants infected with potato virus Y at 7 days p.i. (Pompe-Novak et al, 2005). In rice plants infected with rice dwarf virus, the expression of a gibberellin-biosynthetic enzyme, ent-kaurene oxidase, was repressed, leading to the appearance of dwarf phenotype Itoh et al, 2004;Zhu et al, 2005).…”

“…Systemic infections of plant viruses result from the complex molecular interplay between the host plant and the invading virus (Maule et al, 2000;Golem & Culver, 2003;Whitham et al, 2003;Pompe-Novak et al, 2005). The magnitude of physiological and phenotypic changes in the host during viral infection suggests the involvement of a large number of host genes (Golem & Culver, 2003;Whitham et al, 2006).…”

“…Dissecting the plant gene-expression network that occurs in response to virus infection should assist in a better understanding of the infection process and ultimately in the control of plant viruses. To achieve this, microarray technology has been adopted to profile global gene expression of the host (mainly model plant species) infected with several positive-sense RNA viruses (Golem & Culver, 2003;Whitham et al, 2003;Ishihara et al, 2004;Marathe et al, 2004;Pompe-Novak et al, 2005;Senthil et al, 2005;Dardick, 2007;Shimizu et al, 2007;Yang et al, 2007).…”

Estudio de la interacción entre naranjo amargo y el virus de la tristeza de los cítricos

“…En distintos estudios se ha observado que el desarrollo de la sintomatología va asociado con una represión de los genes relacionados con la pared celular (Shimizu et al, 2007;Yang et al, 2007;Babu et al, 2008). La clorosis característica de las hojas con el síndrome de SY podría ser debida en parte a una reducción en esta etapa de la expresión de genes relacionados con el metabolismo de los azucares e indirectamente con la fotosíntesis (Técsi et al, 1994(Técsi et al, , 1996Maule et al, 2002;Pompe-Novak et al, 2005;Espinoza et al, 2007;Babu et al, 2008).…”
