Transcriptome Analysis of floral organ in Canna indica by RNA-Seq

ABSTRACT: In Canna indica L, 3-4 (occasionally 5) petaloid staminodes and a one-theca stamen with a petaloid appendage constitute the androecium. In order to find out the genetic basis of petaloid development of androecium members, RNA-Seq analysis of petal (P), petaloid staminode (PS), anther (A) and petaloid appendage (PA) were carried out.

In order to find out the genetic basis of petaloid development of androecium members, RNA-Seq analysis of petal (P), petaloid staminode (PS), anther (A) and petaloid appendage (PA) were carried out. P-PS comparison was carried out to find the differences between the two kinds of petal-like organ, and A-PA comparison was conducted to reveal the mechanism for the differentiation of these two parts within stamen.

Transcriptome Sequencing and Assembly of Canna indica Flower

Project description:Canna indica L. is an ornamental plant with petaloid staminodes and only a half fertile stamen in its flowers. The genetic basis for petaloid androecium remains unclear. In order to get comprehensive transcriptome data for further studies, RNA-Seq analysis were carried out. Two libraries from flower primordia and differentiated flowers of Canna indica were constructed and sequenced respectively, and totally 118,869 unigenes were assembled. The unigenes were aligned to the protein databases NR, NT, Swiss-Prot, KEGG, COG and GO (e-value<0.00001), and totally 67,299 unigenes were annotated. Our data constitute a preliminary basis for further studies on flower development of Canna indica.

Genome-wide gene expression of rice cultivar Gui-630 (Indica) X Taiwanjing (Japonica) and mutant lemmata (lem) panicle

Project description:The lem mutant was discovered in a doubled haploid (DH) line derived from the F1 of Gui-630 (Indica)xTaiwanjing (Japonica) by anther culture. The lem mutant did not affect other traits but caused all other floral organs (including palea, lodicule, stamen and carpel) to homeotically transform into lemma or lemma-like structures and caused floral meristem to be indeterminate, thus resulting in the mutant floret consisting of whorls of lemma and lemma-like organs. To identify the global gene expression changes mediated by LEM, we used 57K Affymetrix rice whole genome array to investigate the differences of genome-wide transcriptome between the young panicles of mutant lem versus WT samples during flower development stage. Keywords: rice (Oryza sativa L.),wild-type and lemmata mutant We generate gene expression profiles of rice cultivar Gui-630 (indica)x Taiwanjing (japonica) and mutant lemmata by using 57K Affymetrix rice whole genome array.

Rice transcriptional repressor OsTIE1 controls anther dehiscence and male sterility by regulating JA biosynthesis

Project description:The coordination of pollen viability, stamen filament elongation and anther dehiscence is essential for the successful pollination and reproduction in angiosperms. The hormone jasmonic acid (JA) are crucial for these processes. However, the tight regulation of JA biosynthesis during stamen development is still largely unknown. Here, we demonstrate that the rice (Oryza sativa) ERF-associated amphiphilic repression (EAR) motif-containing protein TCP INTERACTOR CONTAINING EAR MOTIF PROTEIN1 (OsTIE1) tightly regulates JA biosynthesis by repressing TEOSINTE BRANCHED1/CYCLOIDEA/PROLIFERATINGCELLFACTORS (TCP) transcription factor OsTCP1/PCF5 during stamen development. The loss of OsTIE1 function in ostie1 mutants causes male sterility. The ostie1 mutants display inviable pollen, the early stamen filament elongation and the precocious anther dehiscence. JA biosynthesis is activated earlier and JA level is precociously increased in anthers of ostie1. The expression of OsTIE1 is developmentally regulated during stamen development. OsTIE1 is localized in nuclei and has transcriptional repression activity. We further show that OsTIE1 directly interacts with OsTCP1, and overexpression of OsTCP1 caused early anther dehiscence resembling that of ostie1. The expression of genes encoding key enzymes of JA biosynthesis including Oryza sativa lipoxygenase (OsLOX) genes is regulated by the OsTIE1-OsTCP1 complex. Our findings discover that the OsTIE1-OsTCP1 module plays critical roles in stamen development by finely tuning JA biosynthesis, and provides a new foundation to create male sterile plants for hybrid seed production.

The F-box cofactor UFO redirects the LEAFY floral regulator to novel cis-elements

Project description:In angiosperms, flower patterning requires the localized expression of the APETALA3 (AP3) floral homeotic gene involved in petal and stamen development. AP3 is synergistically induced by the master transcription factor LEAFY (LFY) and the F-box protein UNUSUAL FLORAL ORGANS (UFO), but the molecular mechanism underlying this synergy has remained unknown. Here we show that the connection to ubiquitination pathways suggested by the F-box domain of UFO is mostly dispensable and that UFO instead acts by forming a transcriptional complex with LFY on newly discovered regulatory elements. The cryo-electron microscopy structure of the UFO-LFY-DNA complex shows that UFO-DNA contacts allows relocating LFY to novel DNA sites. Finally, we show that this complex has a deep evolutionary origin, largely predating flowering plants. This work unravels an unsuspected role for a member of one of the largest protein families in plants as a modulator of the DNA binding specificity of a master TF.
