Project description:To understand the molecular basis for differences of common bean wild-type and mutant in sulphur amino acid content, transcripts were profiled at four developmental stages of seeds from wild-type SARC1 and major seed storage protein-deficient line SMARC1N-PN1 using a CustomArray 90K array. Microarray data confirmed that transcripts of storage and sulphur-rich proteins and sulphur-metabolism related genes were differentially expressed between the lines. The common bean (Phaseolus vulgaris) mutant line, SMARC1N-PN1 and its wild type, SARC1 used in the microarray experiment were grown in the field in London, ON, in 2009. Four developmental stages of seeds, based on fresh seed weight, were harvested. The stages of seeds used are Stage IV M-bM-^@M-^S cotyledon, 25 mg seed weight; Stage V M-bM-^@M-^S cotyledon, 50 mg seed weight; Stage VI M-bM-^@M-^S maturation, 150 mg seed weight, corresponding to the most active phase of reserve accumulation; and Stage VIII M-bM-^@M-^S maturation, 380 mg seed weight, corresponding to the onset of desiccation, were harvested for total RNA extraction. Four biological replicates for Stage IV and V and 3 biological replicates for Stage VI and VIII.

Project description:TIFY is a large plant-specific transcription factor gene family. A subgroup of TIFY genes named JAZ (Jasmonate-ZIM domain) has been identified as repressors of jasmonate (JA)-regulated transcription in Arabidopsis and other plants. JA signaling is involved in many aspects of plant growth/development and in the defense responses to biotic and abiotic stresses. Here we identified the TIFY genes (designated as PvTIFY) from the legume common bean (Phaseolus vulgaris) and functionally characterized PvTIFY10C as a transcriptional regulator. Twenty-three genes from the PvTIFY gene family were identified through whole genome sequence analysis. Most of these were induced upon methyl-JA elicitation. We selected PvTIFY10C as a representative JA-responsive PvTIFY gene for further functional analysis. Transcriptome analysis via microarray hybridization using the designed Bean Custom Array 90K was performed in transgenic roots of composite plants with modulated -RNAi-silencing or over-expression- PvTIFY10C gene expression. Data were interpreted using Mapman adapted to common bean. Microarray differential gene expression data were validated by real-time qRT-PCR expression analysis. Comparative global gene expression analysis revealed opposite regulatory changes in processes such as RNA and protein regulation, stress response and metabolism in silenced vs. over-expressing roots. These data point to transcript reprogramming -mainly repression- orchestrated by PvTIFY10C. In addition we found that several PvTIFY genes as well as genes from the JA biosynthetic pathway responded to P-deficiency. Relevant P-responsive genes that participate in carbon metabolic pathways, cell wall synthesis, lipid metabolism, transport, DNA, RNA and protein regulation, signaling, were oppositely-regulated in control vs. PvTIFY10C silenced roots. These data indicate that PvTIFY10C regulates, directly or indirectly, gene expression of some P-responsive genes something that could be mediated by JA-signaling.

Our work contributed to the functional characterization of PvTIFY transcriptional regulators in common bean, an agronomically important legume. Members from the large PvTIFY gene family are important global transcriptional regulators that could participate as repressors of the JA signaling pathway. In addition we propose that the JA-signaling pathway that involves PvTIFY genes might play a role in regulating the plant response / adaptation to P-starvation.

Project description:250 adult T. urticae females from the London strain (grown on acyanogenic P. vulgaris cv. Prelude bean plants) were transferred to cyanogenic P. lunatus cv. 8078 bean plants. Thirty-five generations after the host transfer, total RNA was extracted from mites growing on both bean species (London and London-CYANO strain) and used in in a genome-wide gene expression microarray (Sureprint G3 microarray, Agilent) experiment to assess significantly differentially expressed genes (FC ≥ 2 and FDR-corrected p-value < 0.05) between mites grown on P. vulgaris (cv. Prelude) bean plants (London strain) and mites grown for 35 generations on P. lunatus (cv. 8078) bean plants (London-CYANO strain).

Project description:Dry bean (Phaseolus vulgaris L.) seeds are a rich source of dietary zinc, especially for people consuming plant-based diets. Within P. vulgaris there is at least two-fold variation in seed Zn concentration. Genetic studies have revealed seed Zn differences to be controlled by a single gene in two closely related navy bean genotypes, Albion and Voyager. In this study, these two genotypes were grown under controlled fertilization conditions and the Zn concentration of various plant parts were determined. The two genotypes had similar levels of Zn in their leaves and pods but Voyager had 52% more Zn in its seeds than Albion. RNA was sequence from developing pods of both genotypes. Transcriptome analysis of these genotypes identified 27,198 genes in the developing bean pods, representing 86% of the genes in the P. vulgaris genome (v 1.0 DOE-JGI and USDA-NIFA). Expression was detected in 18,438 genes. A relatively small number of genes (381) were differentially expressed between Albion and Voyager. Differentially expressed genes included three genes potentially involved in Zn transport, including zinc-regulated transporter, iron regulated transporter like (ZIP), zinc-induced facilitator (ZIF) and heavy metal associated (HMA) family genes. In addition 12,118 SNPs were identified between the two genotypes. Of the gene families related to Zn and/or Fe transport, eleven genes were found to contain SNPs between Albion and Voyager.

Project description:The pod is the main edible part of Phaseolus vulgaris L. (common bean). The commercial use of the pods is mainly affected by their color. Consumers seem to prefer golden pods. However, planters suffer economic losses because of pod color instability. The aim of the present study was to identify the gene responsible for the golden pod trait in the common bean. ‘A18-1’ (a golden bean line) and ‘Renaya’ (a green bean line) were chosen as the experimental materials. Genetic analysis indicated that a single recessive gene, pv-ye, controls the golden pod trait. A candidate region of 4.24-Mb was mapped to chromosome A02 using bulked-segregant analysis coupled to whole genome sequencing. In this region, linkage analysis in an F2 population localized the pv-ye gene to an interval of 182.9-kb between the simple sequence repeat markers SSR77 and SSR93. This region comprised 16 genes in this region, comprising 12 annotated genes from the P. vulgaris database, and 4 functionally unknown genes. Combined with transcriptome sequencing, we identified Phvul.002G006200 as the potential candidate gene for pv-ye. Sequencing of Phvul.002G006200 identified a single nucleotide polymorphism (SNP) in pv-ye. This SNP is located in the coding region and is responsible for substituting a glutamic acid with an glutamine at position 416 of the pv-ye protein (E416Q). A pair of primers covering the SNP was designed and the fragment was sequenced to screen 316 F2 plants with the ‘A18-1’ phenotype, based on the different site. Our findings showed that the among the 316 mapped individuals, the SNP cosegregated with the ‘A18-1’ phenotype. The findings presented here could form the basis to reveal the mechanism of the golden pod trait in the common bean at the molecular level.

Project description:A wide range of environmental stresses lead to an elevated production of reactive oxygen species (ROS) in plant cells thus resulting in oxidative stress. The biological nitrogen fixation in the legume - Rhizobium symbiosis is at high risk of damage from oxidative stress. Common bean (Phaseolus vulgaris) active nodules exposed to the herbicide Paraquat (1,1 '-Dimethyl-4, 4'-bipyridinium dichloride hydrate) that generates ROS accumulation, showed a reduced nitrogenase activity and ureide content. We analyzed the global gene response of stressed nodules using the Bean CombiMatrix Custom Array 90K, that includes probes from some 30,000 expressed sequence tags (EST). A total of 4,280 ESTs were differentially expressed in oxidative stressed bean nodules; of these 2,218 were repressed. These genes were grouped in 44 different biological processes as defined by Gene Onthology. Analysis with the PathExpress bioinformatic tool, adapted for bean, identified five significantly repressed metabolic path This work presents the transcriptional profile of bean nodules, induced by strain Rhizobium tropici CIAT 899, under oxidative stress, generated experimentally by adding the herbicide Paraquat (1,1 '-Dimethyl-4, 4'-bipyridinium dichloride hydrate) for 48 hours. We analyzed the transcript profile, via microarray hybridization, using the Bean CombiMatrix Custom Array 90K, that includes probes from some 30,000 expressed sequence tags (EST). A total of 4,280 ESTs were differentially expressed in oxidative stressed bean nodules; of these 2,218 were repressed.

Project description:A series of genetically related lines of common bean (Phaseolus vulgaris L.) integrate a progressive deficiency in major storage proteins, the 7S globulin phaseolin and lectins. SARC1 integrates a lectin-like protein, arcelin-1 from a wild common bean accession. SMARC1N-PN1 is deficient in major lectins, including erythroagglutinating phytohemagglutinin (PHA-E) but not α-amylase inhibitor, and incorporates also a deficiency in phaseolin. SMARC1-PN1 is intermediate and shares the phaseolin deficiency. Sanilac is the parental background. To understand the genomic basis for variations in protein profiles previously determined by proteomics, the genotypes were submitted to short-fragment genome sequencing using an Illumina HiSeq 2000/2500 platform. Reads were aligned to reference sequences and subjected to de novo assembly. The results of the analyses identified polymorphisms responsible for the lack of specific storage proteins, as well as those associated with large differences in storage protein expression. SMARC1N-PN1 lacks the lectin genes pha-E and lec4-B17, and has the pseudogene pdlec1 in place of the functional pha-L gene. While the α-phaseolin gene appears absent, an approximately 20-fold decrease in β-phaseolin accumulation is associated with a single nucleotide polymorphism converting a G-box to an ACGT motif in the proximal promoter. Among residual lectins compensating for storage protein deficiency, mannose lectin FRIL and α-amylase inhibitor 1 genes are uniquely present in SMARC1N-PN1. An approximately 50-fold increase in α-amylase inhibitor like protein accumulation is associated with multiple polymorphisms introducing up to eight potential positive cis-regulatory elements in the proximal promoter specific to SMARC1N-PN1. An approximately 7-fold increase in accumulation of 11S globulin legumin is not associated with variation in proximal promoter sequence, suggesting that the identity of individual proteins involved in proteome rebalancing might also be determined at the translational level.
