Specific effects of microRNAs on the plant transcriptome.

Schwab Rebecca R Palatnik Javier F JF Riester Markus M Schommer Carla C Schmid Markus M Weigel Detlef D

Developmental cell 20050401 4

Most plant microRNAs (miRNAs) have perfect or near-perfect complementarity with their targets. This is consistent with their primary mode of action being cleavage of target mRNAs, similar to that induced by perfectly complementary small interfering RNAs (siRNAs). However, there are natural targets with up to five mismatches. Furthermore, artificial siRNAs can have substantial effects on so-called off-targets, to which they have only limited complementarity. By analyzing the transcriptome of plan ...[more]

Comparison of gene expression in wild-type and rpl-1 Arabidopsis inflorescence apices

Project description:The Arabidopsis thaliana REPLUMLESS gene (RPL), also known as PENNYWISE (PNY) and BELLRINGER (BLR) encodes a BEL1-like TALE homeodomain (BLH) transcription factor that controls multiple aspects of meristem and floral development, including meristem maintenance, phyllotaxis, the transition to flowering, stem development and floral organ patterning [1-3]. As part of a screen for genes that mediate the function of RPL in the processes above, we compared gene expression in inflorescence apices of wild-type (Landsberg-erecta) and the rpl-1 mutant [2]. 1.

CONSTANS and jasmonate signaling coordinate floral senescence in Arabidopsis

Project description:Photoperiodic floral initiation in the leaf is controlled by the hub gene CONSTANS (CO) while jasmonates (JAs) control flower senescence. Although both processes are chronologically ordered, no association between them has been described to date. We show that CO protein remains in Arabidopsis flowers after the floral induction, although displaying a different tissue and diurnal pattern than in leaves. We found that changes in CO expression alter flower senescence and abscission by interfering with the JA response, supported by petal specific analysis as well as CO overexpression in JA synthesis and signaling mutants. CO has a ZIM-like domain that mediates interaction with the JA response repressor JAZ3 (jasmonate ZIM-domain 3), inhibiting its repressor activity and activating downstream transcription factors involved in flower senescence. The complex CO-JAZ3 also interacts with the E3 ubiquitin ligase Coronatine Insensitive 1 (COI1) leading to its degradation in the presence of jasmonates. Therefore, the coordinated recruitment of photoperiodic and jasmonate signaling pathways would be an efficient way for plants to chronologically order the floral process and ensure the success of offspring production.

RNAseq experiment to identify differentially expressed genes in dvl/rtfl mutants and DVL overexpresion lines in inflorescence apices of Arabidopsis thaliana

Project description:The lack of visible phenotypes of multiple dvl/rtfl mutants prompted us to compare the transcriptomic signatures of inflorescence apices of wildtype and mutant combinations (specifically dvl1 dvl8 dvl11 rtfl11 dvl19 and dvl8 dvl11 rtfl9 rtfl11 dvl19), as well as dvl1-D mutant, where DVL1 is overexpressed, and 35Spro:DVL8 line. Significant changes in gene expression were caused by the mutation of DVL genes in both quintuple mutant and overexpression backgrounds.

Expression data from Arabidopsis wild type and cdm1 young floral buds

Project description:We used microarray analysis to examine transcriptomic changes in cdm1 mutant, identifying genes potentially regulated by CDM1 by comparing gene expression between cdm1 and wild type young floral buds. Among 375 genes that showed differential expression (P-value <0.05) with >1.5-fold changes between wild type and cdm1, 185 genes were down-regulated by 1.5 to 7.10-folds, whereas 190 genes were up-regulated by 1.5 to 5.82-folds.
