Project description:Genome-wide transcriptome analysis was performed to understand the expression pattern of transcriptomes in tolerant and susceptible subtropical maize genotypes under waterlogging stress condition. Waterlogging stress causes yield reduction in maize (Zea mays). It is important to dissect the genetic circuits that underlie the plant responses to waterlogging. So, the experiment was designed with the following objectives: to understand the expression pattern of transcriptomes in the tolerant and the susceptible genotypes under waterlogging stress; to identify DEGs functioning in important pathways underlying adaptive traits; to co-map bin locations of the transcriptomes with already known QTLs for waterlogging and find synteny with other species; and to generate gene co-expression networks to study cohorts of genes expressed together in modules and functional cluster, while comparing the two genotypes.

Project description:Waterlogging and submergence are major abiotic stresses impairing rapeseed development and hence evaluation of waterlogging tolerance ability is crucial for the development of tolerant lines through breeding approaches. This study investigated submergence impact on the survival rate, physiological responses, and transcriptomic variation of the young seedlings of 706 Brassica napus germplasm. We identified 57 highly tolerant and 109 highly susceptible accessions underwent six days submergence. Most accessions originated from the downstream of Yangtze River region had higher tolerance level. SOD enzymic activity increased both in the five representative tolerant and susceptible genotypes under submergence stress. POD activity also increased in the tolerant genotypes whereas CAT activity decreased, showing a opposite trend compared to the susceptible genotypes. The tolerant genotypes showed less chlorosis and produced less malondialdehyde than that in the susceptible group, while soluble protein content increased more than that in the susceptible genotypes. Transcriptome analysis detected 5,072 and 5,063 up-regulated genes, as well as 3,512 and 3,889 down-regulated genes in the tolerant / susceptible group in comparison to their respective control. Many genes encoding the transcription factors in AP2/ERF, bHLH, MYB, WRKY, and NAC families were also significantly regulated. The differentially expressed genes shared by the two pairs comparison were mainly enriched in such KEGG pathways as circadian rhythm, tryptophan metabolism, and porphyrin and chlorophyll metabolism. The specific pathways in the tolerant group were enriched in carbon metabolism, phenylpropanoid biosynthesis, and biosynthesis of amino acid etc. while the specific pathways in the susceptible group were more distributed in hormone signal transduction, sucrose and starch metabolism, and vitamin B6 metabolism etc. The results uncovered distinct physiological and transcriptomic differences between tolerant and susceptible genotypes.

Two tropical maize (Zea mays L.) inbred lines, HKI1105 (tolerant) and V-372 (susceptible), were used for our experiment. The genotypes were sown in plastic pots filled with loam soil with sandy texture. The plants were watered daily to soil capacity until the application of stress at 28 days after sowing. To impose waterlogging condition, the perforation in the bottom of the pots (35 cm in height) was sealed and the stress treatment was given by watering the pots (5 cm standing water) for seven continuous days. To allow for recovery from stress, the perforations of the pots were unsealed for proper drainage of excess water. The root samples from both genotypes were collected on the 28th, 32nd, 35th and 42nd day after sowing, which represented control, moderate stress, severe stress and post-stress recovery stages, respectively. Two biological replications were used for each comparison.

Project description:Waterlogging is a major abiotic stress causing oxygen depletion and carbon dioxide accumulation in the rhizosphere. Barley is more susceptible to waterlogging stress than other cereals. To gain a better understanding of the effect of waterlogging stress in barley, we carried out a genome-wide gene expression analysis in roots of Yerong and Deder2 barley genotypes under waterlogging and control (well-watered) conditions by RNA-Sequencing, using Illumina HiSeq™ 4000 platform.

Project description:Purpose: To gain a better understanding of the molecular mechanisms that enable de novo AR primordia emergence upon waterlogging, the RNA sequencing-based transcriptomic responses of two contrasting cucumber genotypes, Zaoer-N (waterlogging tolerant) and Pepino (waterlogging sensitive), which differed in their abilities to form AR were compared. Conclusion: This research broadens our understanding of the mechanism underlying waterlogging-triggered ARs emergence, and provides valuable information for the breeding of cucumber with enhanced waterlogging tolerance.

Project description:Hymenoscyphus fraxineus, the causal agent of Ash Dieback (ADB), has been introduced to eastern Europe in the 1990s from where it spread causing decline in European ash populations. However, the genetic basis of the molecular response in tolerant and susceptible ash trees to this disease is still largely unknown. We performed RNA-sequencing to study the transcriptomic response to the disease in four ash genotypes (ADB-tolerant FAR3 and FS36, and ADB-susceptible UW1 and UW2), during a time-course of 7, 14, 21, and 28 days post-inoculation, including mock-infected trees as control samples for each sampling time point. The analysis yielded 395 and 500 Differentially Expressed Genes (DEGs) along the response for ADB-tolerant FAR3 and FS36, respectively, while ADB-susceptible UW1 and UW2 revealed 194 and 571 DEGs, respectively, with most DEGs found exclusively in just one of the genotypes. DEGs shared between tolerant genotypes FAR3 and FS36, included genes involved in the production of phytoalexins and other secondary metabolites with roles in plant defense. Moreover, we identified an earlier expression of genes involved in both pattern- and effector-triggered immunity (PTI and ETI) in ADB-tolerant genotypes, while in ADB-susceptible genotypes both responses were delayed (late response). Overall, these results revealed different transcriptomic expression patterns not only between ADB-tolerant and ADB-susceptible genotypes, but also within these two groups. This hints to individual response in the natural tolerance to ADB, possibly revealing diversified strategies across ash genotypes.

Project description:Background: Soil salinity is a major abiotic stress factor that limit agricultural productivity worldwide, and this problem is expected to grow in the future. Common bean (Phaseolus vulgaris L.) is an important protein source in developing countries is highly susceptible to salt stress. To understand the underlying mechanism of salt stress responses, transcriptomics, metabolomics, and ion content analysis were utilized for response comparison of salt-tolerant and salt-susceptible common bean genotypes in saline conditions. Results: Transcriptome analysis has revealed that the tolerant genotype had increased photosynthesis in saline conditions while the susceptible genotype acted in a contrasting way. The chlorophyll content measurements have backed up this result with increase in tolerant and decrease in susceptible genotype. Transcriptome also displayed a more active carbon and amino acid metabolism for the tolerant genotype as well. Analysis of primary metabolites with GC-MS demonstrated the boosted carbohydrate metabolism in the tolerant genotype with increased sugar content as well as better amino-acid metabolism with the accumulation of glutamate and asparagine and hinted a lowered photorespiration level for the tolerant one. Accumulation of lysine, valine, and isoleucine in the roots of the susceptible genotype suggested a halted stress response pathway. According to ion content comparison, the tolerant genotype managed to block accumulation of Na+ in the leaves while accumulating significantly less Na+ in the roots compared to susceptible genotype. K+ levels increased in the leaves of both genotype and the roots of the susceptible one but dropped in the roots of the tolerant genotype. Additionally, Zn+2 and Mn+2 levels were also dropped in the tolerant roots, while Mo+2 levels were significantly higher in all tissues in both control and saline conditions for tolerant genotype. Conclusion:The results of the presented study have demonstrated the differences in contrasting genotypes and thus provide valuable information on the pivotal molecular mechanisms underlying salt tolerance mainly in common bean, but for all crops.
