MetabolomicsThe natural variance of the Arabidopsis floral secondary metabolites
Application of mass spectrometry-based metabolomics enables the detection of genotype-related natural variance in metabolism. Differences in secondary metabolite composition of flowers of 64 Arabidopsis thaliana (Arabidopsis) natural accessions, representing a considerable portion of the natural var...

MetabolomicsMetabolic alterations in pea leaves during arbuscular mycorrhiza development

Arbuscular mycorrhiza (AM) is known to be a mutually beneficial plant-fungal symbiosis; however, the effect of mycorrhization is heavily dependent on multiple biotic and abiotic factors. Therefore, for the proper employment of such plant-fungal symbiotic systems in agriculture, a detailed underst...

GenomicsMolecular basis for the specification of floral organs by APETALA3 and PISTILLATA (ChIP-Seq)
Characterization of the activities of the transcription factors that AP3 and PI encode throughout flower development using perturbation and ChIPSeq assays in combination with a floral induction system (FIS) that allows a stage-specific analysis of flower development. Examination of genomic regions b...

GenomicsOrchestration of Floral Initiation by APETALA1
The MADS-domain transcription factor APETALA1 (AP1) is a key regulator of Arabidopsis flower development. To understand the molecular mechanisms underlying AP1 function, we identified its target genes during floral initiation using a combination of gene expression profiling and genome-wide binding s...

GenomicsOrchestration of development by the bifunctional transcription factor, APETALA2
The emerging picture of transcriptional regulation is one of unexpected complexity. It is now clear that single transcription factors control hundreds, if not thousands, of direct targets by binding their genomic loci, but it is not understood how many of these are major players and how many are sup...

TranscriptomicsAth_Agilent_v1_Riechmann array expression profile apetala1
Comparion of gene expression profiles of wild-type and apetala1 inflorescences The gene expression profile of inflorescences of the floral homeotic mutant apetala1 was compared to wild-type inflorescences (Ler) using a whole-genome oligonucleotide array (Agilent, custom-commercial). Experiment was p...

TranscriptomicsTranscriptional profiling of Persea americana flowers
The debate on the origin and evolution of flowers has recently entered the field of developmental genetics, with focus on the design of the ancestral floral regulatory program. Flowers can differ dramatically among angiosperm lineages, but in general, sterile perianth organs surrounding stamens (ma...

TranscriptomicsTranscription profiling of Arabidopsis ap1-1 and cal-1 mutations and expressing a fusion between AGAMOUS and the rat glucocorticoid receptor (35S:AGGR) during early flower development in Arabidopsis
Floral organs, whose identity is determined by specific combinations of homeotic genes, originate from a group of undifferentiated cells called the floral meristem. In Arabidopsis, the homeotic gene AGAMOUS (AG) terminates meristem activity and promotes development of stamens and carpels. To unders...

TranscriptomicsTranscription profiling of Arabidopsis thaliana AP1::AtIPT4 transformants vs wild type plants to identify the candidate genes responsive to cytokinin
The aim of this experiment is to identify the candidate genes responsive to cytokinin in Arabidopsis floral development. For this purpose, AtIPT4 gene under the control of the AP1 promoter was transformed into wild type plants of Arabidopsis. The transcriptional profiles of the young inflorescence o...
