RNA-Seq analysis of adventitious rooting zone of Arabis alpina main stem during extended cold exposure.

(Submitter supplied) Arctic alpine species experience extended periods of cold and unpredictable conditions during flowering. Thus, often, alpine plants use both sexual and asexual means of reproduction to maximise fitness and ensure reproductive success. We used the arctic alpine perennial Arabis alpina to explore the role of prolonged cold exposure on adventitious rooting. We exposed plants to 4 °C for different durations and scored the presence of adventitious roots on the main stem and axillary branches. more...

APETALA2‐like transcription factor in shoot architecture and perennial traits

(Submitter supplied) Polycarpic perennials maintain vegetative growth after ﬂowering. PERPETUAL FLOWERING 1 (PEP1), the orthologue of FLOWERING LOCUS C (FLC) inArabis alpina regulates ﬂowering and contributes to polycarpy in a vernalisation-dependent pathway. pep1 mutants do not require vernalisation to ﬂower and have reduced return to vegetative growth as all of their axillary branches become reproductive. To identify additional genes that regulate ﬂowering and contribute to perennial traits we performed an enhancer screen of pep1. more...

Cytokinin-promoted secondary growth and nutrient storage in the perennial stem zone of Arabis alpina

(Submitter supplied) Perennial plants maintain their life span through several growth seasons. Arabis alpina serves as model Brassicaceae species to study perennial traits. A. alpina lateral stems have a proximal vegetative zone with a dormant bud zone, and a distal senescing seed-producing inflorescence zone. We addressed the questions of how this zonation is distinguished at the anatomical level, whether it is related to nutrient storage, and which signals affect the zonation. more...

Keep a distance to be different: axillary bud initiating at a distance to the shoot apical meristem are crucial for the perennial life style of Arabis alpina

(Submitter supplied) Purpose: In higher plants, perennialism is achieved through axillary buds and side-shoots that stay vegetative. This work aims to analyze the pattern of axillary bud (AB) formation in the perennial model plant Arabis alpina and to study the role of LATERAL SUPPRESSOR (AaLAS) gene in this process. Methods: This study combines stereomicroscopic analysis with RNA sequencing to monitor how patterns of AB formation and gene expression correlate. more...

RNAseq analysis of Arabis alpina buds in the dormant zone (V2) and buds in the growing zone (V3) at the end of vernalization (+0) and 5 days later (+5d)

(Submitter supplied) Arabis alpina, similar to woody perennials, has a complex architecture with a zone of axillary vegetative branches and a zone of dormant buds that serve as perennating organs. We show that floral development during vernalization is the key for shaping the dormant bud zone by facilitating a synchronized and rapid growth after vernalization and thereby causing an increase in auxin transport, response and endogenous indole-3-acetic acid (IAA) levels in the stem. more...

Divergence of regulatory networks governed by the orthologous transcription factors FLC and PEP1 in Brassicaceae species.

(Submitter supplied) Genome-wide landscapes of transcription factor (TF) binding sites (BSs) diverge during evolution, conferring species-specific transcriptional patterns. The rate of divergence varies in different metazoan lineages but has not been widely studied in plants. We identified the BSs and assessed the effects on transcription of FLOWERING LOCUS C (FLC) and PERPETUAL FLOWERING 1 (PEP1), two orthologous MADS-box TFs that repress flowering and confer vernalization requirement in the Brassicaceae species Arabidopsis thaliana and Arabis alpina, respectively. more...

Genome-wide profiling of H3K4me3, H3K27me3 H3K27me1 and 5mC enrichment and mRNA levels in young leaves of Arabis alpina

(Submitter supplied) Chromatin, DNA and RNA were extracted from young A. alpina Pajares primary stem leaves. Chromatin and DNA methylation immunoprecipitation experiments were performed using commercially available antibodies and analyzed by Illumina sequencing (ChIP-seq and MeDIP-seq). Transcriptome data were generated by RNA-seq.

Mechanisms of age-dependent response to winter temperature in perennial flowering of Arabis alpina.

(Submitter supplied) Transcriptomic profile of Arabis alpina apex enriched material. We compared apices from plants grown for 2 weeks in long days (20°C) (juvenile) with apices from plants grown for 8 weeks in long days (20°C) (adult) and apices from plants grown for 2 weeks and then shifted in vernalization for 4 weeks with apices from plants grown for 8 weeks and than shifted to vernalization for 4 weeks.
