Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
In depth temporal profiling of transcript changes at 10 time points during germination in Arabidopsis seed was carried out. The time course utilised, encompassed seed maturation, stratification, germination and post-germination and provided a global investigation into the tightly regulated, phasic changes that define seed germination.
Publication Title
In-depth temporal transcriptome profiling reveals a crucial developmental switch with roles for RNA processing and organelle metabolism that are essential for germination in Arabidopsis.

Description
The antagonistic interaction between iron (Fe) and phosphorus (P) has been noted in the area of plant nutrition. To understand the physiology and molecular mechanisms of this interaction, we studied the growth performance, nutrient concentration, and gene expression profiles of root and shoot segments derived from 10-d-old rice (Oryza sativa) seedlings under four different nutrient conditions: (1) full strength of Fe and P (+Fe+P); (2) full strength of P and no Fe (-Fe+P); (3) full strength of Fe and no P (+Fe-P); and (4) without both Fe and P (-Fe-P).

Description
Arabidopsis ABA hpersensitive germination2-1 mutant shows an enhanced sensitivity to ABA. This mutant has higher levels of endogenous ABA. This mutant also exhibited SA hypersensitivity and dwarf phenotype. Regarding SA hypersensitivity, ahg2-1 exhibits higher endogenous SA level and an enhanced resistance to pathogenic bacteria. Since AHG2 encodes the Arabidopsis polyA specific ribonuclease that is involved in mRNA degradation, presumably abnormal accumulation of some mRNAs confers the unique phenotype. Transcriptome analyses are expected to offer information on the target of AHG2. In order to eliminate secondary effects of higher levels of ABA and SA, ahg2-1abi1-1 and ahg2-1sid2-2 double mutants were also examined. The transcriptome data revealed that; ahg2-1 confers unique gene expression profiles, ABA and SA affect the expression profiles of this mutant but many genes are independent of those plant hormone responses. Comparing with expression profiles of other mutants indicated that the ahg2-1 might affect mitochondrial function.

Illumina HiSeq 2000
Description
Male germ cells express the widest repertoire of transcript variants in mammalian tissues. Nevertheless, factors and mechanisms underlying such pronounced diversity are largely unknown. The splicing regulator Sam68 is highly expressed in meiotic cells and its ablation results in defective spermatogenesis. Herein, we uncover an extensive splicing program operated by Sam68 across meiosis, primarily characterized by alternative last exon (ALE) regulation in genes of functional relevance for spermatogenesis. Lack of Sam68 preferentially causes premature transcript termination at internal polyadenylation sites. Overall design: RNA-Seq data for purified spermatocytes and spermatids isolated from Sam68+/+ and Sam68-/- mice.

Description
RNAseq profiling of 10 time points during germination in Arabidopsis, from freshly harvested seed, through mature seed, stratification, germination and to post-germination. Overall design: Total RNA was extracted from Arabidopsis seeds at 10 time points during germination in triplicate. The time points were: freshly harvested seed (H), seeds following 15 days of ripening (0 h), seeds after; 1 h of stratification (1 h S), 12 h of stratification (12 h S), 48 h of stratification (48 h S), followed by seed collected 1 hour into the light (1 h SL), 6 hours into the light (6 h SL), 12 hours into the light (12 h SL), 24 hours into the light (24 h SL) and 48 hours into the light (48 h SL).
