Suppression of the Gene Affects the Level of ROS Depending on Light and Cold.

The E3 ubiquitin-protein ligase HOS1 is an important integrator of temperature information and developmental processes. HOS1 is a negative regulator of plant cold tolerance, and silencing leads to increased cold tolerance. In the present work, we studied ROS levels in plants, in which the gene was silenced by disruption of the open reading frame via CRISPR/Cas9 technology.

Proteomic Analysis of Proteins Related to Defense Responses in Plants Transformed with the Oncogene.

During -plant interaction, the gene is transferred into the plant genome and is stably inherited in the plant's offspring. Among the numerous effects of on plant metabolism, including the activation of secondary metabolism, its effect on plant defense systems has not been sufficiently studied. In this work, we performed a proteomic analysis of -expressing plants with particular focus on defense proteins.

The rolB plant oncogene affects multiple signaling protein modules related to hormone signaling and plant defense.

The rolB plant oncogene of Agrobacterium rhizogenes perturbs many biochemical processes in transformed plant cells, thereby causing their neoplastic reprogramming. The oncogene renders the cells more tolerant to environmental stresses and herbicides and inhibits ROS elevation and programmed cell death. In the present work, we performed a proteomic analysis of Arabidopsis thaliana rolB-expressing callus line AtB-2, which represents a line with moderate expression of the oncogene.
