- Affymetrix Rice Genome Array (rice)
Description
The aim of this study was to minimize the number of candidate genes responsible for salt tolerance between a pair of rice varieties (CSR27 and MI48) with contrasting level of salt tolerance by bulked segregant analysis of their recombinant inbred lines. Microarray analysis of RNA extracted from the tolerant and susceptible parents without and with stress showed 798 and 2407 differentially expressed genes, respectively. The number of differentially expressed genes was drastically reduced to 70 and 30, by pooling the RNAs from ten extreme tolerant and ten extreme susceptible RILs due to normalization of irrelevant differentially expressed genes between the parents.

- Affymetrix Citrus Genome Array (citrus)
Description
Nucellar embryony is a form of apomixis found in citrus where somatic nucellar cells differentiate into embryos and are included in the seed resulting from the normal sexual process. The nucellar cells giving rise to adventive embryo start proliferating prior to anthesis and fully differentiate obtaining nourishment from sexually derived endosperm. To identify transcripts differentially expressed during nucellar embryo initiation we have taken RNA samplesfrom different developing stages of ovules from polyembryonic (cv. Vaniglia Sanguigno) and monoembryonic (cv. Temple) cultivars. We used microarray for a detailed analysis of global gene expression during nucellar embryony initiation and development. We have further validated the differentially expressed genes using qRT-PCR.

Description
The aim of this study was to identify candidate genes responsible for grain number per panicle between a pair of rice varieties (Pusa 1266 and Pusa Basmati 1) by combining QTL analysis with expression analysis. Microarray analysis of RNA extracted from the panicle primordia showed 2741 differentially expressed genes. The differentially expressed genes were shortened to 18 on the basis of their occurance in the QTL region (responsible for grain number regulation) detected in RIL population derived from Pusa 1266 and Pusa Basmati 1.

Description
In the terms of vaccine efficacy and duration of protection in malaria vaccination is major concern against malaria. On the other hand, it is facing complications in development and administration to the host. However, whole sporozoites vaccination (WSV) is far more efficacious than any other alternative strategy. We have found that the intermittent sporozoite challenge to immune mice following RAS vaccination extends the longevity of sterile protection by maintaining CD8+T cell memory responses to LS infection and also helps in CD8a+DCs accumulation and activation in liver. Consequently, there has been great interest in elucidating and understating the sterile immunological response at mechanistic level. The information we have generated can then potentially be used in generation of next generation vaccine with improved efficacy and duration of protection. In this work, to elucidate the host initial immune response underlying the protective effects of a WSV in shaping the protected sterile protection and advances its immunogenicity in the future, a high-throughput RNA sequencing technology was used to investigate the immunization related gene expression patterns of mouse immunized with radiation attenuated sporozoites (RAS) vaccine.

Description
Introduction: The Plant Organelle RNA Recognition (PORR) domain proteins are nucleus-encoded RNA-binding proteins that have acquired specific roles in organelle RNA metabolism as splicing factors of chloroplast group II introns. LEFKOTHEA (At5g62990) is a nuclear gene encoding a PORR domain protein that carries a transit peptide (TP) and monopartite or bipartite nuclear localization signals (NLS). These motifs result in dual-targeting of LEFKOTHEA to the nucleus and chloroplasts implying a role in the splicing of chloroplast group II introns and nuclear pre-mRNA introns. Therefore, we examined the splicing efficiency of plastid and nuclear genes in lefko2 mutant.Methods: The lefko2 mutant was isolated from a genetic screen of an M2 EMS-mutagenized Arabidopsis thaliana Columbia (Col-0) background seed population. The lefko2 mutant allele has a white cotyledon phenotype caused by a G to A mutation in the coding region resulting in a Glycine (G) 373 to Aspartic acid (D) conversion. Total RNA was extracted using plant RNA kit spin columns with an on-column DNase treatment from lefko2 mutant and wild-type Arabidopsis cotyledons. The quantity and integrity of the RNA was assessed using a NanoDrop 1000 spectrophotometer and agarose gel electrophoresis. RNA-seq libraries were generated using the TruSeq Low Input kit according to the manufacturer's instructions (Illumina). Sequencing was performed on an Illumina HiSeq 2000 instrument at BGI (Beijing Genomics Institute). Raw reads were filtered into clean reads and aligned to the Arabidopsis genome (TAIR10). RNA-seq data were analyzed using the SOAP (Release 2.121) with parameters “-s 40 -l 32 -v 3 -r 2” and the TopHat/Cufflinks pipeline (version 2) with parameters “-p 16 --solexa1.3-quals --segment-length 30 --segment-mismatches 2 -r 20 --mate-std-dev 20 --library-type fr-unstranded”. We generated 480 million paired-end reads (101 bp in length) for each sample. On average, about 90% of these reads could be unambiguously aligned to the TAIR10 reference genome sequence. Alternative splicing events were detected for lefko2 and wild-type using Spladder. Intron retention events detected in wild-type were filtered out from lefko2 or vice-versa, and visualized using the Integrative Genomics Viewer (IGV) tool.Results: Splicing defects were observed in numerous nuclear genes of lefko2 cotyledons compared to wild type. Among them, intron retention (IR) events were the most prominent. Further, the fidelity of 5' splice site (5'SS) donor and 3'SS acceptor splicing was disturbed in lefko2 cotyledons. To less extend, exon skipping (ES) defects were also detected.Conclusions: Detailed nuclear splicing events were widely observed in lefko2 cotyledons demonstrating a prevalent role of LEFKOTHEA in the splicing of nuclear pre-mRNA introns.Overall design: RNA-seq libraries were generated using the TruSeq Low Input kit according to the manufacturer's instructions (Illumina). Sequencing was performed on an Illumina HiSeq 2500 instrument at BGI (Beijing Genomics Institute).
