Expression data from cynosure (cyn) mutant and its CYNOSURE (CYN) wild-type at before flowering and 5 days after pollination stage

Project description:To assess further the role of CYN in relation to integument morphogenesis, gametophytic cell fate specification, embryogenesis and endosperm development, we compared the expression profiles between the cyn mutant and wild-type at two different stages(before flowering and 5 days after pollination stage) of ovule development by microarray analysis. Specifically, we confirmed significant changes of up- or down-regulation in some genes required for several biological processes, such as auxin efflux & polarity & cell differentiation, flower and embryonic development, signal transduction.These results supported that MADS protein CYN could function both as a transcriptional activator and repressor, directly and/or indirectly interacted with dozens of potential target genes (including MADS or non-MADS transcription factors) involved in developmental and hormonal pathways. Three independent biological replicates of cyn mutant and wild-type panicle mRNA at two different stages of ovule development were used for microarray experiments. To perform microarray analysis, the samples were pooled by 20 panicles from 10 individual plants at before flowering and 5 days after pollination stage.

Udt1-1 anther and Wild type_anther

Project description:A series of microarray experiments by using RNA sources from UDT1-1 mutant type- and wild type-anthers at stages from meiosis to young microspore. In conjuction, microarray experiments by using RNA sources from wild type_Palea/lemmas in the flowering stage and wild type anther at pollen mitosis were performed in a time course design and compared to the microarrays of UDT1-1 mutant type- and wild type-anthers. Keywords: time-course

Transcription profiling of rice wild type Zhonghua11 and mutant gif1 in filling stage

Project description:To reveal the underlying molecular mechanism of Gif1 action in the control of grain filling and yield improvement, we performed transcriptional profiling of wild type Zhonghua11 and mutant gif1 plants in early filling stage on a global scale using the Affymetrix GeneChip Rice Genome Array Experiment Overall Design: Rice caryopsis were harvested in 7 days after flowering and three biological repeats were performed on Zhonghua11 (wild-type) and gif1 (mutant), respectively.

Transcription profiling of Arabidopsis wild-type and lwd1lwd2 double mutant to investigate the role of LWD1 and LWD2 in Arabidopsis photoperiod regulation

Project description:Transcriptome analysis has revealed a light-regulated WD (tryptophan and aspartate)-containing protein, LWD1. LWD1 and LWD2 share greater than 90% amino acid sequence homology. The lack of phenotype changes in the lwd1 or lwd2 single mutant implies that the proteins function redundantly. The lwd1lwd2 double mutant, however, has an early flowering phenotype under both long-day (LD) and short-day (SD) conditions. Functional complementation experiment revealed that LWDs are indeed responsible for the defect in photoperiod sensing in lwd1lwd2 double mutant plants. The expression of LWD1 exhibits a diurnal pattern and peaks before dawn. The period length of oscillator (CCA1, LHY, TOC1 and ELF4) and output (CCR2 and CAB2) genes in the lwd1lwd2 double mutant is significantly shorter than that in wild-type Arabidopsis under free running condition. Under entrainment conditions, the expression phase of oscillator (CCA1, LHY, TOC1 and ELF4) and output (GI, FKF1, CDF1, CO and FT) genes shifts ~3 hr forward in the lwd1lwd2 double mutant. Our data indicated that the early flowering phenotype in lwd1lwd2 plants is contributed by the significant phase shift of CO and, therefore, an increased expression of FT before dusk under SD conditions. Our data imply that LWD1/LWD2 proteins function in close proximity to the circadian oscillators for the regulation of photoperiod sensing. Experiment Overall Design: Two biological replicates were performed to examine the differential gene expression between wild-type and lwd1lwd2 double mutant. The plants were grown under 12 h L/ 12 h D for 31 days before harvesting their above ground tissues at ZT5-9.

Molecular interaction between PHO2 and GIGANTEA reveals a new crosstalk between flowering time and Pi homeostasis in rice

Project description:Using a yeast to hybrid screen, it was found that PHO2, a key regulator of phosphate homeostasis, could interact with GIGANTEA, a key regulator of flowering time. In addition, mutant analysis revealed that both the pho2 and gi mutants shared similar phenotypes, both at the phosphate and flowering time levels. We used microarrays to analyse the effects of each mutation (pho2 or gi) on global gene expression, and assessed the proportion of genes similalry regulated in both mutants, in both shoots and roots. Wild-type (Nipponbare), pho2 and gi knock-out rice plants were grown to 21-days before harvesting root and shoot separately.
