Knockdown of MLO genes reduces susceptibility to powdery mildew in grapevine

TL;DR: The knockdown through RNA interference of VvMLO6, 7, 11 and 13 seemed to be important for PM resistance, whereas a role for Vv MLO11 does not seem likely and the knockdown of V vMLO7 in combination with V v MLO6 and VVMLO11 reduced PM severity up to 77%.
Journal ArticleDOI

Evaluation of transgenic tomato plants ectopically expressing the rice Osmyb4 gene

TL;DR: Transgenic tomato plants overexpressing Osmyb4 acquired a higher tolerance to drought stress and to virus disease, however, the transgenic plants did not appear to be more cold tolerant than the WT, in any tested condition.
Journal ArticleDOI

Antisense reduction of thylakoidal ascorbate peroxidase in Arabidopsis enhances paraquat-induced photooxidative stress and nitric oxide-induced cell death.

TL;DR: In this paper, the production and characterization of Arabidopsis plants containing a transgene in which the tAPX is inserted in antisense orientation, is described, and the results suggest that tAPx, besides the known ROS scavenging role, is also involved in the fine changes of H2O2 concentration during signaling events.
Journal ArticleDOI

Optimizing Escherichia coli as a protein expression platform to produce Mycobacterium tuberculosis immunogenic proteins

TL;DR: The goal of purifying large quantities of soluble antigens effective in generating immunological response against M. tuberculosis by a robust, controlled, scalable and economically feasible production process is reached.
Journal ArticleDOI

Efficient heat-shock removal of the selectable marker gene in genetically modified grapevine

TL;DR: A system for marker gene removal after selection of transgenic plants has been tested in grapevine based on a binary vector containing a heat-shock-inducible promoter which activates a recombinase to produce the excision of a FRT-flanked box.
