N6-methyladenosine RNA methylomes in woodland strawberry fruit at three different development stages.

Project description:For exploring whether mRNA m6A modification participates in the regulation of strawberry fruit ripening, we performed m6A-seq in woodland strawberry fruit at three different development stages, including the S6 stage (almost 15 days post-anthsis (DPA)), the RS1 stage (21 DPA), and the RS3 stage (27 DPA), with three biological replicates. mRNA methylome analysis reveals that m6A methylation prevalently distributes in the strawberry transcriptome and highly enrichs in the coding sequence, stop codon and 3’ untranslated region.

ChIP-seq of Fragaria.vesca

Project description:Histone modifications mediate between genes and environment in plant growth and developmental events. To characterize the histone modification signatures in strawberry, we performed ChIP-seq experiments for seven histone marks in the immature and mature fruits, and leaves of the woodland strawberry F. vesca ('Ruegen'). The seven histone marks include H3K9/K14ac, H3K27ac, H3K4me1, H3K4me3, H3K36me3, H3K27me3 and H3K9me2. In addition, to reveal the effect of the histone deacetylase FvHDA6, H3K9/K14a was profiled in FvHDA6-OE fruits.

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

Project description: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. The role of AaLAS was studied using an RNAi approach. Results: During vegetative development, ABs initiate at a distance to the SAM, whereas after induction of flowering ABs initiate adjacent to the SAM. Dormant buds are established before onset of vernalization. Transcript profiles of ABs initiated at a distance were different from that of the SAM, whereas transcript patterns of buds initiated in close proximity were similar to the corresponding SAM. Knock-down of AaLAS leads to loss of both dormant buds and vegetative side-shoots, strongly compromising perennial life style. Conclusions: AB formation is regulated differently during vegetative and reproductive development. New meristems that show gene expression profiles different from the SAM are established at a distance to the SAM. AaLAS plays an essential role in perennial life cycle modulating the establishment of dormant buds and vegetative side-shoots.

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)

Project description: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. Floral development during vernalization is associated with the development of axillary buds in subapical nodes. Our transcriptome analysis indicated that these buds are not dormant during vernalization but only reach sustained growth after the return to warm temperatures. Floral and subapical vegetative branches grow after vernalization and inhibit the development of the buds below. Dormancy in these buds is regulated across the A. alpina life cycle by low temperatures and by apical dominance in a BRANCHED 1 dependent mechanism.

RNA-seq time course analysis of potato WT and BRC1b-RNAi axillary buds in response to short-day conditions

Project description:Purpose: observe the difference between potato (Solanum tuberosum ssp. andigena) WT and BRC1b RNAi axillary buds in response to the transition from long-day to short-day conditions. The time course includes four time points: Long days, after 2 days in short days, 1 week in short days and 2 weeks in short days. Methods: stem were flash-frozen in N2(l) one hour after dawn and the axillary buds were dissected in the cold room. The four axillary buds bellow the third visible node counting from the apex (those most likely to produce tubers in RNAi line) were collected. RNA was extracted with FavorPrep™ Plant Total RNA Mini Kit from FAVORGEN. DNA was degraded in the column with RNase-free DNase I (Roche). Three biological replicates were used and each replicate is a pool of axillary buds from 4 plants.

Comprehensive transcriptomic dataset for early stage fruit development in woodland strawberry Fragaria vesca

Project description:Fragaria vesca, a diploid woodland strawberry with a small and sequenced genome, is an excellent model for studying fruit development. The strawberry fruit is unique in that the edible flesh is actually enlarged receptacle tissue. The true fruit are the numerous dry achenes dotting the receptacleM-^Rs surface. Auxin produced from the achene is essential for the receptacle fruit set, a paradigm for studying crosstalk between hormone signaling and development. To investigate the molecular mechanism underlying strawberry fruit set, next-generation sequencing was employed to profile early-stage fruit development with five fruit tissue types and five developmental stages from floral anthesis to enlarged fruits. This two-dimensional data set provides a systems-level view of molecular events with precise spatial and temporal resolution.

Identification of genes differentially expressed in dormant versus active axillary shoot apical mersitems.

Project description:The aim of this study is to identify genes differentially expressed during the transition between dormancy and activity in axillary shoot apical meristems. We have chosen to study this by comparing mRNA populations from the axillary buds of the auxin over-responding, apically dominant axr3-1 mutant of Arabidopsis,with those from the axillary buds of the auxin resistant axr1-12 bushy mutant. Preliminary investigation using cDNA AFLP has been successful in identifying differentially expressed transcripts in the buds of these two genotypes, thus demonstrating the importance of this study, however this is a time consuming procedure. Axillary buds from axr3-1 are seen to arrest at an early stage when the buds are approximately 2mm long and harvested at this point. Buds of a similar size were harvested from axr1-12 plants and the RNA extracted using Qiagen columns.These two mRNA samples will represent the dormant and active buds to be comparedin this experiment. The plants from which these buds were harvested were grown in adjacent p40 trays in a plant growth room. Between two and three buds were harvested from each plant.
