Iron_deficiency gene expression in Arabidopsis wild type and yellow stripe1-like1/3 (ysl1ysl3) double mutants.

ABSTRACT: When iron is withdrawn from the growth medium of plants, large changes in gene expression have been observed. A double mutant with T-DNA insertions in the Arabidopsis yellow stripe1-like1 (At4g24120) and yellow stripe3-like (At5g53550) genes shows strong iron-related phenotypes. This study is intended to uncover the gene expression changes that occur in leaves and roots of the double mutant compared to wild type plants.

Effect of SlNOR-like1 knockout on gene expression related to cuticle metabolism in tomato exocarp

Project description:To investigate the function of SlNOR-like1 in the regulation of cuticle formation in tomato fruits, we established nor-like1 mutants by CRISPR/Cas9. We then performed gene expression profiling analysis using data obtained from RNA-seq of tomato exocarp of wild type (WT) and nor-like1 mutant at mature green (MG) stage.

Expression data from Arabidopsis Col and rglg1/2 mutant in response to Fe deficiency

Project description:Iron is an essential element for almost all organisms, catalyzing numerous essential redox reactions by virtue of its unique electrochemical properties. Iron levels in cells need to be carefully balanced. Rglg1/2 is an Arabidopsis mutant which display a pleiotropic phenotype partly resembling iron-deficient plants.To dissect global transcriptional regulation of gene expression in iron-deficient plants, we conducted genome-wide proteomic and transcriptomic surveys of leaves and roots from iron-sufficient and iron-deficient Col-0 wild-type plants and rglg1 rglg2 double mutants.

JA-INDUCIBLE MYC2-LIKE1 acts as a repressor and negatively regulates jasmonate signaling in Arabidopsis

Project description:Jasmonate (JA) is a plant hormone that controls trade-offs between plant growth and responses to biotic and abiotic stresses. Although recent studies uncover core mechanism for JA-induced responses in Arabidopsis thaliana, it remains elusive how plants attenuate those responses. We report here that a basic-helix-loop-helix type transcription factor named JA-INDUCIBLE MYC2-LIKE1 (JAM1) acts as a transcriptional repressor and negatively regulates JA signaling. Arabidopsis plants expressing the chimeric repressor for JAM1 exhibited a substantial reduction of JA responses, including JA-induced inhibition of root growth, accumulation of anthocyanin, and male fertility. These plants were also compromised in resistance to attack by Spodoptera exigua. Conversely, jam1-4 loss-of-function mutants showed enhanced JA responsiveness, including increased resistance to the insect attack. Competitive binding of JAM1 and MYC2 to the target sequence of MYC2 suggested negative regulation of JA signaling by JAM1 and suppression of MYC2 function. These results indicate that JAM1 plays a pivotal role in fine-tuning of JA-mediated stress responses and plant growth by negatively regulating JA signaling.

Yellow nutsedge co-opts a seed-like proteome in oil rich tubers

Project description:Drought is the prime stressors that land plants have to overcome since their dawn. One strategy that land plants employ is to limit water loss and to transport water via a vascular system, another is to produce desiccation tolerant cells and tissues. In most flowering plants, the latter strategy is limited to seeds and to some extend pollen. Common to desiccation and drought tolerance is the accumulation of small osmolytes and proteins with protective functions. Also common to both strategies is the accumulation of neutral lipids, foremost triacylglycerol (TAG), in cytosolic lipid droplets (LDs) with especially high levels being reached in embryonic tissues. Here, we investigated yellow nutsedge (Cyperus esculentus), a monocot, perennial C4 plant. This species produces stolon-derived underground tubers that can fully desiccate and remain viable for years. Yellow nutsedge stands out, as its tubers store 25-30 % of their dry mass in lipids especially TAG, similar to seeds. We generated nanoLC-MS/MS-based proteomes in five replicates of four stages of tuber development and compared them to the proteomes of roots and leaves, yielding 2257 distinct protein groups. Our data reveal a striking upregulation of hallmark proteins of seeds in the tubers. A deeper comparison to a previously published proteome of Arabidopsis seeds and seedlings indicate that indeed a seed-like proteome was co-opted. This was further supported by an analysis of the proteome of a lipid-droplet enriched fraction of yellow nutsedge, which also displayed seed-like characteristics.

EST mining of yellow potato and gene expression profiling of its infection by P. infestans using SAGE - SOLEXA

Project description:The late blight pathogen, Phytophthora infestans has a broad host range within the Solanaceae family, including yellow potato (Solanum phureja). The disease caused by P. infestans in S. phureja is poorly understood and is a major concern in Colombia. Expressed Sequence Tag (EST) libraries obtained from a normalized library constructed from healthy plant tissue revealed high levels of sequence similarity between S. phureja and S. tuberosum. Then, utilizing Serial Analysis of Gene Expression and high-throughput sequencing (SAGE-Solexa), we characterized yellow potato gene expression during infection by P. infestans. Four-week-old yellow potato plants were inoculated with P. infestans and were collected at 12 and 72 hours post inoculation for RNA extraction. We detected differentially expressed genes by comparing inoculated to non-inoculated and resistant to susceptible plants. The discovery and characterization of the proteins mediating this host–pathogen interaction enable the understanding of the pathosystem and is the key for developing resistant plants. Keywords: SAGE-Solexa, inoculation response, transcript profiling, Solanum phureja, Phytophthora infestans Four-week-old yellow potato (Solanum phureja) plants were inoculated with Phytophthora infestans and were collected and flash frozen in liquid nitrogen at 12 and 72 hours post inoculation, as well as mock inoculated, for RNA extraction. 2 yellow potato cultivars (resistant and susceptible) were used for each experiment. Mock inoculated plants were collected in each replicate. RNA obtained from each of the three biological replicates was pooled to obtain a single RNA sample for each timepoint X cultivar combination. A total of 6 different SAGE libraries were thus obtained. For all libraries, Illumina sequencing was performed at Canada´s Michael Smith Genome Sciences Centre.

Transcriptome analysis of transgenic plants with ectopic expression (driven by 35S promoter) of At14a-Like1 (AFL1, At3g28270) YFP fusion protein.

Project description:Transcriptome analysis was used to identify genes differentially expressed in transgenic plants expressing At14a-Like1 (AFL1, At3g28270)) YFP fusion protein compared to wild type. Transcriptome analysis was performed using seedlings grown under either control conditions or low water potential stress with the objective of identifying genes associated with the increased growth caused by AFL1 overexpression under stress. The analysis identified 172 genes up-regulated and 525 genes down regulated in 35S:AFL1-YFP relative to wild type in control condtions. In the stress treatment 398 genes were up regulated and 722 down regulated in 35S:AFL1-YFP plants relative to wild type. The criteria used to identify up and down regulated genes was fold change greater than 1.5 and corrected p value ≤0.05.

Expression data of fruits in the wildtype and ORR tomato plants

Project description:An Ac/Ds transposon tagged mutant population was screened for changes in visible fruit phenotypes. One line showed orange, yellow sectors in the fruit and was named Orange ripening (Orr), its transposase free offspring showed Mendelian segregation yielding red, yellow and orange fruit bearing plants in a ratio of 1:2:1. Crossing the an orange fruit plant line to the wild-type yielded only plants bearing yellow fruit. A cross between the yellow fruit bearing progeny yielded 26 plants having red and 17 plants having yellow fruit, suggesting an over-dominant allele. Using inverse PCR analysis showed an insertion in the putative subunit M of the tomato Ndh complex. Subsequently, an Orr Ds transposon excision line was recovered which only showed red pigmented fruit. Here, we describe microarray profiling of tomato fruits from wild-type, heterozygous and homozygous Orr insertion plants and from fruits harvested from the Orr excision line. Keywords: mutant wild type
