Plant genes affected by Solanum tuberosum and Colorado potato beetle interaction

ABSTRACT: Potato leaves From Solanum tuberosum var. Kennebec will be wounded and oral secretions from 4th instar CPB will be isolated and added to the plants as described by Kruzmane et al (2002, Physiol. Plantarum 115:577-584). The leaf from the 6th node of the potato plant will be wounded or wounded and treated with oral secretions from CPB. Unwounded leaves from node 1-5 of the wounded and wounded plus oral secretions plants will be harvested as systemic material. The leaves will be harvested after 4 hrs and RNA will be isolated. 4 hrs was chosen because this represents a time when early and late induced genes should both be present. In addition, the leaf from the 6th node will be subjected to feeding by CPB that have been raised on potato leaves and starved for 16 hrs immediately prior to infestation. Insects will be allowed to feed for 1 hr and the leaves will be harvested after 3 additional hrs. An additional set of plants will be used to infest the leaf on the 6th node for 4 hrs. Leaves from the 6th node will be collected from uninfested plants after 4 hrs as a control. Three sets of 6-12 plants will be used for each sample. Keywords: Direct comparison

Potato virus Y infection hinders potato defence response and renders plants more vulnerable to Colorado potato beetle attack

Project description:In the present study molecular interactions between potato plants, Colorado potato beetle (CPB) larvae and Potato virus YNTN (PVYNTN) were investigated by analyzing gene expression in potato leaves. mRNA samples of secondary PVYNTN-infected (CPB_PVY) and healthy potato plants (CPB_H) cultivar Igor and of RNAi coi1-silenced (CPB_coi1) and non-transformed (CPB_NT) potato plants cultivar Desiree collected 24 h post CPB infestation and respective control non-infested samples (CONT_PVY, CONT_H, CONT_coi1, CONT_NT).

Small RNAs deep sequencing from sweet potato in wounding stress

Project description:Plant microRNAs (miRNAs) have emerged as important regulators in developmental processes and stress responses in plants. To identify the wound-responsive miRNAs in the leaves of sweet potato, small RNA deep sequencing was conducted on unwounded and wounded leaves (30 min). Total RNAs were isolated for library construction and analyzed by RNA-sequencing via Illumina Genome Analyzer IIx platform. About 16 million total reads were obtained for each sample.

Effect of two potato viruses, PLRV and PVY, on potato gene expression in Russet Burbank

Project description:Potato plants (cv. Russet Burbank) were grown as in vitro plantlets, and transplanted into 12-cm pots in Sunshine Mix #2 (peat/perlite mix) supplemented with slow release fertilizer (Osmocoat) in the greenhouse. The experiment was conducted in the summer of 2004 at Moscow, ID. Plantings were staggered to facilitate collection of volatiles and leaf samples during a short harvest window for all times of all treatments. Infectious Green Peach Aphids were raised on PLRV-infected potato plants; test plants were infected by placing 10 infectious aphids on a leaf in a clip cage for 48 h. The control plants for PLRV were similarly treated with aphids that had been raised on uninfected potato plants. A local isolate of PVYO was inoculated mechanically using purified virus (5 ìg ml-1) in buffer (50 mM Na2HPO4, 20 mM Na2SO3 pH 7.0) lightly rubbed onto a leaf previously dusted with carborundum. Control plants for PVY were treated in the same manner using buffer without PVY. The RNA samples were made from systemically affected leaves, excluding the actual leaves inoculated by aphids or that received the mechanical infection. Leaf volatiles were concurrently collected from equivalent plants; aliquots of frozen leaf samples were sent for metabolite analysis prior to RNA extraction. Leaf harvests were made 1, 3, 7, 14, and 28 d post-inoculation. Keywords: Direct comparison

Current injection and distal wound response in Arabidopsis thaliana

Current injection and distal wound response in Arabidopsis thaliana

Project description:These data represent two experiments, one on wounding leaves and one based on injecting current into leaves. We first analyzed transcript levels in leaf 13 when leaf 8 was wounded. Transcripts levels in leaf 8 were then analyzed after current injection. Sample handling and normalisations were identical between experiments. Leaf 8 was wounded with forceps. 1 h later, leaf 13 was harvested. Unwounded leaf 13 was used for controls. For current injected (40 ?A, 10 s) versus non-current injected leaves, samples were harvested 1h after current injection. Non-current injected leaves used as control. In each case leaf 8 was used.

oligosaccharide treatment - 24 hpt-Effect of oligosaccharide treatments on gene expression.

Project description:ra10-03_eliciteur - oligosaccharide treatment - 24 hpt - Do the treatments modify gene expression in a way that can give us a hint as to their use in crop protection? What is the effect of the adjuvant on gene expression? - 6,5-week-old arabidopsis plants grown in short-day photoperiod were spray-treated with water, an adjuvant or oligosaccharides in the adjuvant (10 plants per condition, 4 replicates per condition). 6 hrs, 24 hrs and 48 hrs after the treatment, samples were taken (2 7mm diameter leaf disks per plant, from medium-aged leaves), frozen in liquid nitrogen, and later on total RNA was extracted.

12plex_pea_2013_02_g -Water stress and seed filling in pea

Project description:12plex_pea_2013_02 - 12plex_pea_2013_02_g - What is the effect of a moderate water stress on seed filling (reserve accumulation) and nitrogen remobilisation in pea (Pisum sativum) - Pea plants (genotype Cameor) were subjected to a moderate water stress at the beggining of the seed filling period (12 Days After Pollination) of the second flowering node for a period of 8 days. Samples were collected from Well Watered (WW) plants at the beginning of the stress imposition (point A, T=0), and from Water-Stressed (WS) and WW control plants at the end of the drought period (point B, T=+8). Samples named SEED consisted of seeds from the pod of the second flowering node (seed-WW-A, seed-WW-B and Seed-WS-B). Samples named LEAF consisted of the leaves and stem sections from the two vegetative nodes below the first flowering node (leaf-WW-A, Leaf-WW-B and Leaf-WS-B). Each sample consited of a pool of 3 individual plants and 4 repetitions per condition were carried out.
