Differential expression for rice-gall midge interaction

ABSTRACT: We exposed Kavya rice seedlings to different gall midge biotypes, GMB1 and GMB4M, which exhibit incompatible and compatible interactions, respectively. Expression study in Kavya seedlings using pooled samples of stem meristematic tissues 24, 48, 96, and 120 hr after GMB1 and GMB4M infestation when compared with uninfested control. Three replicates each condition.

The Asian rice gall midge [Orseolia oryzae (Wood-Mason)] is an important rice pest causing an annual average yield loss of about US $80 million in India. Rice varieties possess several discrete resistance (R) genes conferring resistance against the pest in two distinct ways, i.e., with (HR+ type) or without (HR- type) the expression of hypersensitive reaction (HR). The aim of the present work is to understand the molecular basis of compatible and incompatible (HR- type) rice gall midge interacti ...[more]

Expression data from plant tissues during incompatible interaction between the rice host and its major pest, the Asian rice gall midge

Project description:During an incompatible or compatible interaction between rice (Oryza sativa) and the Asian rice gall midge (Orseolia oryzae), a lot of genetic reprogamming occurs in the plant host We used microarray to know the changes occuring in the resistant host (indica rice variety RP2068-18-3-5) when challenged by avirulent biotype of gall midge (GMB 1). During this incompatible interaction the resistance in the host is manifested by a hypersenstive response. Using microarray data, we identified distinct classes of up- and down-regulated genes during this process. Tissues from the stem region (feeding site of insect larvae) of the plants that were exposed to gall midge, were taken for RNA extraction and hybridization on Affymetric microarrays. For control, tissues were taken from the corresponding region of plants that were not exposed to gall midge.

Photoreceptor control of shoot meristem activity and leaf initiation

Project description:When Arabidopsis seedlings are grown in the dark, their shoot meristem remains in a repressed state and does not develop leaves. The tight control of leaf development by light provides the opportunity to analyse a fundamental plant developmental process in its very early stages. We have observed that activation of photoreceptors in dark-grown seedlings leads to a rapid and dramatic increase in mitotic activity in and around the shoot meristem. Cotyledons also exhibit an induction of cell cycle activity by light, but this consists of endoreduplication and occurs later. Many other processes take place upon induction by light, including the development of the photosynthetic apparatus and the synthesis of sunscreens, but these processes are expected to take place in both the leaf primordia and the cotyledons. We have used this information to carry out a whole transcriptome analysis of shoot meristem activation and early stages of leaf development by light. For this we dissected the shoot apical regions from seedlings grown in the dark or 1, 2, 6, 24, 48 or 72 h after transfer to light. We also dissected cotyledons from equivalent seedlings grown in the dark or 1 or 6 h after transfer to light. From these samples we obtained RNA used for hybridisations against the ATH1 GenChip. 16 samples were used in this experiment.

Transcript profiling of auxin/cytokinin crosstalk in the Arabidopsis primary root apex

Project description:AtIPT8/pga22 seedlings (gain-of-function mutant in Ws background; Sun et al. 2003, Plant Physiology 131, pp167-176) were grown on vertical plates for 7 days in LD. The seedlings were then incubated directly on the plate with medium containing 5 uM 17-beta-estradiol (for induction of the IPT8 gene) or 5 uM trans-zeatin for 12 and 24 h. 5 mm primary root tips were harvested from the seedlings and pooled for microarray analysis. Total RNA was isolated from the samples with the RNeasy Plant Mini Kit from Qiagen. 14 samples were used in this experiment.

Nuclear gene expression in response to chloroplast division inhibition

Project description:The aim of this investigation is to analyse the effect on nuclear gene expression of inhibition of chloroplast division. Transgenic Arabidopsis lines (Ler) were generated that contained a chemically inducible promoter (XVE) upstream of AtMinD1. AtMinD1 encodes a product involved in chloroplast division; overexpression of AtMinD1 leads to chloroplast division inhibition. 6 samples were used in this experiment. Three treatments were performed: Treatment 1: Empty vector control seedlings (transformed with PER-10 only) were sown onto lehle, sprayed at 13 days old with 2uM 17-B-estradiol (inducer) and harvested 24 hours later. Treatment 2: Seeds were sown on lehle containing inducer and sprayed every 24 hours with 2uM inducer until harvested at 14 days old. Treatment 3: Seeds were sown on lehle plates, sprayed at 13 days old with 2uM inducer and harvested 24 hours later. For all three treatments, seedlings were grown in constant light conditions, and tissue was harvested from 14-day-old seedlings (4 rosette leaves) and snap frozen in liquid nitrogen before RNA preparation.

Cross-species Detection in Barley1 GeneChip Array

Project description:This study was conducted to evaluate the efficiency of cross-species detection in Barley1 GeneChip array. We hybridized cRNA derived from first leaves of barley green seedlings (as a control), as well as the same stage of seedling leaf from representative genotypes of wheat, oat, rice, maize, and sorghum. Ten to twenty seedlings for each species were harvested and pooled for RNA preparation, labeling, and hybridization. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Rico Caldo. The equivalent experiment is BB1 at PLEXdb.] species: Barley(2-replications); species: Wheat(2-replications); species: Oat(2-replications); species: Sorghum(2-replications); species: Corn(2-replications); species: Rice(2-replications)

Expression data from 7-day-old Arabidopsis emf2 mutant, rescued emf2 mutant harboring 35S::BoEMF2.1, WT Columbia ecotype and WT harboring 35S::BoEMF2.1 named transWT

Project description:Arabidopsis emf2 mutants bypass vegetative development and flowering upon seed germination. We introduced a broccoli BoEMF2.1 gene into emf2 mutants and obtained rescued emf2 plants that harbored 35S::BoEMF2.1. We found that BoEMF2.1 can partially rescue the phenotype of emf2 to that of WT. We used microarrays to study the global program of gene expression and to identify genes misexpressed in the Arabidopsis emf2 mutant that had been rescued by 35S::BoEMF2.1. 7-day-old seedlings of WT, transWT, emf2 and rescued emf2 Arabidopsis were used for RNA extraction and hybridization on Affymetrix microarrays.

Expression data from aerial parts of 14-day-old wild-type and GFP-TIE1-15 Arabidopsis seedlings

Project description:TIE1 regulates leaf development by repressing leaf differentiation because the semi-dominant mutant tie1-D by activation tagging displays small and hyponastic leaves and the differentiation of leaf epidermal cells is delayed in the tie1-D mutant, whereas disruption of TIE1 causes epinastic leaves with early differentiated epidermal cells. We used microarrays to investigate the molecular base underpinning the phenotypes of TIE1-overexpressing plants. Aerial parts of 14-day-old seedlings from wild-type and GFP-TIE1-15 were collected for RNA extraction and hybridization on Affymetrix microarrays.
