Metabolomics3D Imaging and metabolomic profiling reveal higher neuroactive kavalactone contents in lateral roots and crown root peels of Piper methysticum (kava)

BACKGROUND: Kava is an important neuroactive medicinal plant. While kava has a large global consumer footprint for its clinical and recreational use, factors related to its use lack standardization and the tissue-specific metabolite profile of its neuroactive constituents is not ...

TranscriptomicsTranscription profiling of Arabidopsis slr1 mutant and wild type lateral root segments treated with auxin
Lateral root initiation was used as a model system to study the mechanisms behind auxin-induced cell division. Genome-wide transcriptional changes were monitored during the early steps of lateral root initiation. Inclusion of the dominant auxin signaling mutant solitary root1 (slr1) identified genes...

TranscriptomicsRNA-seq GLV6 overexpression during lateral root initiation in Arabidopsis thaliana
The goal of this experiment was to identify the downstream targets of the GOLVEN6 peptide signaling pathway in Arabidopsis thaliana, specifically during lateral root initiation. Using an estradiol inducible GLV6 overexpression construct in wildtype and rgi1rgi5 double mutant (mutant in receptors for...

TranscriptomicsTranscription profiling by array of Arabidopsis wild type and an ARF7/ARF19 double knockout mutant roots dissected into 5 developmental zones
Arabidopsis seedlings, of both wild-type and an ARF7/ARF19 double knockout mutant, were grown to 7 days post-germination. The roots were then dissected into 5 developmental zones, the meristem, early elongation zone, late elongation zone, mature root and lateral root zone. The sections then underwen...

TranscriptomicsA systemic view of coordinated root responses to NO3- heterogeneous environment in Arabidopsis
We investigated the morphological roots decisions of Arabidopsis in a NO3- heterogeneous medium. To do so, we used the Split-Root System which is an experimental set up to assess root decisions in nutrient heterogeneous medium. Split-root plants have been subjected to three different treatments. ‘Co...

TranscriptomicsPhosphate Starvation of Maize Inhibits Lateral Root Formation and Alters Gene Expression in the Lateral Root Primordium Zone
Low phosphate concentrations are frequently a constraint for maize growth and development, and therefore, enormous quantities of phosphate fertilizer are expended in maize cultivation, which increases the cost of planting. Low phosphate stress not only increases root biomass but can also cause signi...

TranscriptomicsExpression data from Arabidopsis seedlings upon LRIS using NAA (1-Naphthaleneacetic acid) or non-auxin-like lateral root inducer naxillin
The acquisition of water and nutrients by plant roots is a fundamental aspect of agriculture and strongly depends on root architecture. Root branching and expansion of the root system is achieved through the development of lateral roots and is to a large extent controlled by the plant hormone auxin....

TranscriptomicsRice Lateral Root Inducible System timeseries
To transcriptionally characterize lateral root development in rice, we subjected the rice LRIS to genome-wide transcript profiling via RNA-sequencing. Taking into account the appearance of the first (stage I primordium) cell divisions starting from 6 hours after NAA treatment, we sampled at 2 hours ...

TranscriptomicsTranscript profile changes associated with lateral root fasciation in temperature-sensitive mutants
Control of the dimensions of organ primordia is crucial for proper organogenesis in the development of multicellular organisms. Lateral root formation is a major type of plant organogenesis important for postembryonic development of the root system. Lateral root formation begins with a few rounds of...
