24-hour herbivory exposure of VHb-expressing Populus tremula x Populus tremuloides

Project description:The expression of stress-related genes induced by feeding of chestnut moth larvae (Conistra vaccinii L.) was studied with Vitreoscilla hemoglobin-expressing (VHb) and non-transgenic hybrid aspen lines (Populus tremula x P. tremuloides). Besides the herbivore-injured leaves (L1), cDNA microarray analyses were conducted using uninjured leaves of hybrid aspen lines positioned above (A) and below (B) the herbivory exposed leaves. Two-condition experiment, control vs. herbivory exposure. Two hybrid aspen lines: non-transgenic V617 and VHb expressing V617 /45. Of each plant, three leaf types were analysed: the injured/uninjured leaf (L1) and nonorthostichous leaf positioned above (A) and below (B). Biological replicates: 3. On each array, two samples representing L1, A or B leaf type of control and herbivory treatment of either V617 or V617/45 line. line V617: wt_A_rep1-3, wt_B_rep1-3, wt_L1_rep1-3 line V617/45: VHb_A_rep1-3, VHb_B_rep1-3, VHb_L1_rep1-3 leaf type A: wt_A_rep1-3, VHb_A_rep1-3 leaf type B: wt_B_rep1-3, VHb_B_rep1-4 leaf type L1: wt_L1_rep1-3, VHb_L1_rep1-5

Thermospermine-induced transcriptomic changes in Populus stem

Project description:Thermospermine-induced transcriptomic changes were explored in Populus tremula x P. tremuloides. Transgenic hybrid aspen plants expressing 35S::POPACAULIS5 were compared to wild-type hybrid aspen under the influence of PGRs and depleted from PGRs.

Expression of seaweed genes induced by perwinkle grazing

Project description:The aim of this study was to elucidate changes in gene expression related to the induced anti-herbivory response in the brown seaweed Fucus vesiculosus. Microarray hybridizations were used to identify genes differentially expressed in response to grazing by the periwinkle Littorina obtusata. This study shows that modifications in gene expression occur simultaneously to a reduced palatability and that defence induction entails reallocation of resources from primary to secondary metabolism with down-regulation of photosynthesis.

Hepatic BCL6 and plasma triglycerides regulate sexual dimorphism in tissue tolerance [set 2]

Project description:Hepatic gene expression shows sexual dimorphism. Here, we investigated the role of BCL6 in establishing sexual dimorphism in hepatic gene expression and created Bcl6Flox/Flox,Alb-Cre mice and performed RNAseq from livers of 4- and 8-week-old male and female Ctrl and BCL6 liver knock-out mice.

Grazing-induced expression of seaweed genes

Project description:The aim of this study was to elucidate which changes in gene expression are related to the induced anti-herbivory response in the brown seaweed Fucus vesiculosus. Microarray hybridizations were used to identify genes differentially expressed in response to grazing by the isopod Idotea baltica. This study shows that modifications in gene expression occur simultaneously to a reduced palatability and that defence induction entails reallocation of resources from primary to secondary metabolism with down-regulation of photosynthesis and degradation of storage compounds. Total RNA of Fucus vesiculosus pieces that were or were not previously grazed by Idotea baltica for 15 and 18 days (3 biological replicates each) was hybridized against pooled RNA from 4 F. vesiculosus pieces that were collected before onset of grazing (day 0).
