(Submitter supplied) Plants have the ability to shed organs that are no longer in use. In Arabidopsis thaliana abscission of floral organs involves cell wall remodeling and cell expansion prior to cell wall dissolution. IDA encodes a secreted peptide that signals through the leucine-rich repeat receptor-like kinases (LRR-RLKs) HAESA (HAE) (At4g28490) and HASEA-LIKE2 (HSL2) (At5g65710).

(Submitter supplied) The receptor-like protein kinases encoded by HAESA (HAE) and HAESA-LIKE 2 (HSL2) are essential for floral organ abscission in Arabidopsis thaliana and the double hae hsl2 mutant fails to abscise. Expression of HAE and HSL2 is specific to Abscission Zone (AZ) cells and is higher in stage 15 flowers than in earlier developmental stages. By stage 16 floral organs have begun to abscise, suggesting that HAE HSL2 are most active in stage 15 flowers. more...

(Submitter supplied) In order to investigate possible roles of IDL and PIP/PIPL peptides, the transcriptomic response of Arabidopsis seedlings to treatment with PIPL3 peptide was analysed. PIPL3 (At4g37295) was chosen, as no functional data was available for this peptide; furthermore, PIPL3 was expressed in leaf tissue during seedling stages. Transcriptomic responses to 3 hours PIPL3 peptide treatment suggested a role in regulation of biotic stress responses and cell wall modification.

(Submitter supplied) Inflorescence architecture of Arabidopsis thaliana is regulated by ER-EPFL4/6 signaling module. To analyze the genes governed by this module, the transcriptional profiles of er-2 (allelic to er-106) mutant and epfl4 epfl6 double mutant were investigeted.

(Submitter supplied) To understand ta-siRNA-mediated regulation network in response to abiotic stress during flower development, gene expression profiles of flowering buds between rdr6-15 and wild-type under moderate drought stress and control condition were measured using microarray. 512 genes were bilaterally regulated by drought stress signal and RDR6-mediated signal.

(Submitter supplied) Plant peptide containing sulfated tyrosine 1 (PSY1) has been reported to promote cell expansion and differentiation in the elongation zone of roots. To further understanding of PSY1 based cell elongation, a full genome microarray study was conducted on wild type and receptor (psy1r) mutant plants after PSY1 treatment. This approach led us to elucidate the components involved in PSY1 based cell elongation.

(Submitter supplied) To extend our previous knowledge from our gene expression studies on Leaf Abscission zone using Affymetrix microarray chip we have employed whole transcriptome analysis by NGS as a discovery platform to identify and add the transcripts to pre-existing database. We designed the Customized AZ Microarray chip with the transcripts obtained from NGS (includes novel transcripts), pre existing Agilent probes, and some additional transcripts from previous databases. more...

(Submitter supplied) The cell wall is a defining feature of plant cells and glues cells to each other. To overcome this physical constraint, plants must process and disconnect cell wall linkages during growth and development. However, little is known about the mechanism guiding cell-cell detachment and cell wall remodeling. Here, we identify two neighboring cell types in Arabidopsis that coordinate their activities to control cell wall processing, thereby ensuring precise abscission to discard organs. more...

(Submitter supplied) Although bodyguard (bdg), lacerata (lcr) and fiddlehead (fdh) mutations affect three unrelated genes, they trigger similar effects, i.e. ectopic organ fusion, increase of cuticle permeability. After performing cutin and wax analyses on these Arabidopsis thaliana mutants, which did not coincide with the putative enzyme functions, we hypothesised that these mutations trigger a complex response which may be visible at the transcriptional level. more...

(Submitter supplied) Housekeeping degradation of normal ribosomal RNA in eukaryotes is completed by the RNase T2 family of ribonucleases. This family of ribonucleases is found through eukaryotes, and the Arabidopsis RNase T2 which degrades ribosomal RNA is RNS2. A null mutant in RNS2, rns2-2, has higher levels of RNA, vacuolar accumulation of rRNA and constitutive autophagy. We used microarray to detail the global changes in gene expression in response to mutation of RNS2 (rns2-2) and identified key biological processes differentially regulated in response to this mutation.

(Submitter supplied) In Angiosperms, the continuation of plant species is intricately dependent on the funiculus multifaceted role in nutrient transport, mechanical support, and dehiscence of seeds. SEEDSTICK (STK) is a MADS-box transcription factor involved in seed size and abscission, and one of the few genes identified as affecting funiculus growth. Given the importance of the funiculus to a correct seed development, allied with previous phenotypic observations of stk mutants, we performed a transcriptomic analysis of stk funiculi from floral stage 17, using RNA-sequencing, to infer on the deregulated networks of genes. more...
