De novo genome assembly of faba bean (Vicia faba L.) leaf transcriptome provide novel insights into the drought stress tolerance mechanisms

Project description:Drought is a major limiting constraint to faba bean production worldwide, including Tunisia. However, molecular mechanisms underlying faba bean responses to drought stress are not well understood. In this context, transcriptome analysis by RNA-seq was performed to investigate drought-related genes and construct a network of faba bean drought stress response and tolerance. De novo assembly of the transcriptome generated 26,728 differentially expressed genes (DEGs). Of these, 13,920 were up-regulated and 12,808 down-regulated in faba bean drought-stressed leaves. Moreover, a total of 10,800 simple sequence repeats (SSRs) and 2130 transcription factors involved in major metabolic pathways including abscisic acid (ABA)-dependent and -independent signaling pathway were identified. GO, KOG and KEGG enrichment analyses revealed that these DEGs were involved in several important processes including photosynthesis, flavonoid biosynthesis, response to stimulus and abiotic stress, reactive oxygen species (ROS) scavengers, signal transduction, biosynthesis of secondary metabolites and transporters, suggesting the involvement of these important pathways in faba bean response to water deficit. Various stress proteins such as late embryogenesis abundant proteins (LEA), dehydrins (DHNs) and heat shock proteins (HSPs) have been identified and their expression was robustly upregulated in drought-stressed leaves, indicating their key contribution to drought response and adaptation by conferring protection and providing stability to faba bean plant cellular processes under water deficit. The reliability of the RNA-seq results was confirmed by the analysis of 10 randomly selected genes using qRT-PCR. Taken together, these findings help advancing our knowledge and can guide breeding programs aimed at improving the tolerance of faba bean to drought stress.

Comparative physiological, biochemical and proteomic analyses reveal key proteins and crucial regulatory pathways related to drought stress tolerance in faba bean (Vicia faba L.) leaves

Project description:Drought is one of the most crucial environmental stresses limiting faba bean growth and productivity in the Mediterranean region. In order to explore how the faba bean plant responds to drought stress, a physiological and proteomic analysis was performed in leaf tissue. All physiological parameters were affected by drought. The physiological mechanism underlying the response of faba bean leaves to drought was therefore attributed to the alleviation of oxidative stress via the accumulation of organic solutes such as proline and to the synergistic action of the antioxidant enzyme system (CAT, SOD, APX and GPOX). Proteomic analysis identified 2000 proteins from faba bean leaves, of which were 81 differentially expressed. Of those, 45 were upregulated and 36 were downregulated under drought treatment. GO and KEGG enrichments indicated differentially abundant proteins (DAPs) associated with photosynthesis, antioxidants/detoxifying enzymes, molecular chaperones, biosynthesis of amino acids and secondary metabolites, signal transduction, energy and carbohydrate metabolism and metabolic enzymes. The current results provide evidence for a complex synergetic pathway, in which ROS detoxification mechanisms and photoprotection constituted the major aspect of drought tolerance in faba bean leaves. These results offer a foundational basis regarding the molecular mechanism involved in drought resistance within the faba bean species

Air-classified faba bean protein concentrate is efficiently utilized as a dietary protein source by post-smolt Atlantic salmon (Salmo salar)

Project description:High-quality sources of protein for the formulation of feeds of carnivorous fish species such as Atlantic salmon are currently being sought. In an earlier screening trial we evaluated for the first time in Atlantic salmon (Salmo salar) the applicability of air-classified faba bean (Vicia faba) protein concentrate (BPC) inclusions in combination with soy protein concentrate (SPC) and fishmeal (FM) using parr as a model. Based on the results in parr in freshwater, the present study tested the hypothesis that BPC can effectively replace SPC as a dietary protein source in post-smolt Atlantic salmon in seawater. Herein we compare three dietary treatments, including BPC0 (no BPC), BPC20 (20% BPC) and BPC40 (40% BPC). Full details on diet formulation are available in the publication.

Molecular analysis of growth-limiting drought stress in Brachypodium leaves

Project description:To explore the usefulness of Brachypodium distachyon for drought studies, a reproducible in soil drought assay was developed. Spontaneous soil drying led to a 45% reduction in leaf size, and this most mostly due to a decrease in cell expansion, whereas cell division remained largely unaffected by drought. To investigate the molecular basis of the observed leaf growth reduction, Brachypodium leaf 3 was dissected in three zones, namely the proliferation, expansion and mature zone, and subjected to transcriptome analysis using a Affymetrix whole-genome tiling array. This approach allowed us to highlight that transcriptome profiles of different developmental leaf zones respond differently to drought. Several genes and biological processes involved in drought tolerance were identified. Mainly, we observed an increased energy availability in the proliferation zone along with an upregulation of sterol synthesis that may influence membrane fluidity.

Transcriptome analysis of Indian mulberry leaf tissue

Project description:The mian goal of the study was to identify drought responsive genes of Indian mulberry (Morus alba L.) leaf tissue. Drought stress was imposed at whole plant leve; usig gravimetric approach. Leaf tissue was harvested 14 days post drought stress imposition and used for transcriptome analaysis. Two levels of drought stress (100% and 40% soil field capacity) was maintained by controlled irrigation. The leaf tissue was collected, total RNA was isolated converted to cDNA and used for analysis

Global gene expression analysis of cotton (Gossypium hirsutum L.) under drought stress in leaf tissue.

Project description:Transcriptome analysis in cotton under drought stress. To study the molecular response of drought stress in cotton under field condition global gene expression analysis was carried out in leaf tissue. Gossypium hirsutum cv. Bikaneri Nerma was used for the gene expression analysis. Cotton plants were subjected to drought stress at peak flowering stage. Leaf samples were collected when the soil moisture content was 19.5% which is 50% of the normal control plots. Gene expression profiles in drought induced and their respective control samples were analyzed using Affymertix cotton Genechip Genome arrays to study the global changes in the expression of genome.
