Expression of the Arabidopsis TRANSPARENT TESTA 2 (TT2) MYB family transcription factor leads to massive accumulation of proanthocyanidins (PAs) in hairy roots of Medicago truncatula. Microarray analysis showed that TT2 induces genes for flavonoid/PA biosynthesis, transcription factors, and a large number of genes of unknown function. A second microarray dataset identified genes that were preferentially expressed in the M. truncatula seed coat. Comparison of the two datasets defines target genes ...[more]

Transcription profiling of all major organ systems of Medicago truncatula to create a gene expression atlas

Project description:Medicago truncatula, which has a relatively small diploid genome, has been adopted as a model species for legume genomics. To enhance its value as a model, we have generated a gene expression atlas that provides a global view of gene expression in all major organ systems of this species, with special emphasis on nodule and seed development.

Marchantia abiotic stress combination and diurnal gene expression atlas

Project description:In this study, we set to take advantage of Marchantias less complex signalling architecture to better understand how plants respond to environmental cues such as stress and time of the day, to modulate the expression of genes and biological pathways. To this end, we constructed an abiotic stress gene expression atlas of Marchantia comprising seven abiotic stresses (darkness, high light, cold, heat, nitrogen deficiency, salt, mannitol) and their pairwise combinations (e.g., cold + salt). We also measured gene expression at six timepoints of a day (12h light/ 12h darkness)

Transcription profiling of pistils from Arabidopsis wild type, ant-4 mutant and ino-1mutant plants at different developmental stages

Project description:This experiment was designed to identify genes expressed preferentially in the two integuments of the Arabidopsis ovule. Pistils from wild type and two ovule mutants were compared against each aintegumenta-4 (ant-4) which lacks both integuments and inner no outer (ino-1) which lacks the outer integument. Genes that are highly expressed only in the integuments were expected to be reduced in expression in the mutants, as compared with wild type. Pistils containing ovules through all stages of ovule development prior to pollination were pooled for one experiment (FULL arrays), and for two separate experiments, a set of early differentiation stages (EARLY arrays) and a set of later differentiation stages (LATE ARRAYS) were pooled. Wild type and mutant lines are in the ecotype Landsberg erecta.

Extensive imprinted gene expression in Arabidopsis endosperm

Project description:Some flowering plant and vertebrate genes are expressed primarily or exclusively from either the maternal or paternal allele, a phenomenon called genomic imprinting. Flowering plant imprinted gene expression has been described primarily in endosperm, a terminal nutritive tissue consumed by the embryo during seed development or after germination. Imprinted expression in Arabidopsis thaliana endosperm is orchestrated by differences in cytosine DNA methylation between the paternal and maternal genomes, as well as by Polycomb group (PcG) proteins. Currently only eleven imprinted Arabidopsis genes are known. Here we use extensive sequencing of cDNA libraries to identify many new paternally and maternally imprinted genes in A. thaliana endosperm, including transcription factors, proteins involved in hormone signaling, and epigenetic regulators. The imprinted status of many maternally-expressed genes is not altered by mutations in the DNA-demethylating glycosylase DEMETER, the DNA methyltransferase MET1 or the core PcG protein FIE, indicating that these genes are regulated by novel mechanisms or deposited from maternal tissues. We did not find any imprinted genes in the embryo. Our results demonstrate that imprinted gene expression, particularly from the maternal genome, is an extensive, mechanistically complex phenomenon that likely affects multiple aspects of seed development.

Transcrition profiling of shoots from related model and cultivated Lotus plant species following salt acclimation

Project description:Many plant researchers have applied genomic tools to model species to identify abiotic stress responsive genes that might be useful for improving stress tolerance in crops. However, it is unclear whether this translational approach will be successful given the complexity of abiotic stress tolerance. We carried out a functional genomic (ionomic, transcriptomic and metabolomic) comparison of three model and three forage species of the genus Lotus with varying tolerance to salinity. Transcriptome analysis showed that about 60 % of expressed genes were responsive to salt treatment in one or more of the six species tested, but less than 1 % was responsive in all genotypes. Therefore, genotype-specific responses overshadowed conserved transcriptional responses to salinity and represent an impediment to translational genomics. Fortunately, 'triangulation' from multiple species enabled the identification of a core set of conserved and tolerant-specific responses that could provide durable tolerance across genotypes.
