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

ABSTRACT: 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

Influence of dietary inclusion of a wet processed faba bean protein concentrate on post-smolt Atlantic salmon (Salmo salar)

Project description:In the present study, a faba bean protein isolate (wBPC) with almost ~80 % crude protein produced by a wet process was investigated in feeds for Atlantic salmon in seawater. Four dietary treatments were tested including one treatment with high inclusion of fishmeal (400 g kg-1, named FM) and three treatments with low fishmeal (216 g kg-1) and increasing inclusions of faba bean protein concentrate (0, 70 and 140 g kg-1) substituting soy protein concentrate (236, 125 and 45 g kg-1), named SPC, BPC7 and BPC14 respectively.

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.

P. syringae pv. phaseolicola NPS3121 responses to bean leaf extract

Project description:Many genes involve in pathogenicity and virulence are induced only in plant or in the presence of host components. Bean leaf extract was obtained from healthy bean leaves. In this work we investigated the effect of bean leaf extract on the transcriptomic profile of the bacterium, when grown at low temperature in minimal medium with or without extract from healthy bean leaves.

The response to substitution of soybean with faba bean protein concentrate on hepatic transcriptome of Atlantic salmon (Salmo salar)

Project description:The production of carnivorous fish such as Atlantic salmon (Salmo salar) is dependent on the availability of high quality protein required as a sustainable substitute for the formulation of the feeds. Plants have arguably the greatest potential, however a major limitation is associated with the presence of anti-nutritional factors. Investigating novel raw materials involves understanding the physiological consequences of the substitution. The primary aim of the present study was to assess the metabolic response of salmon to increasing inclusion of air-classified faba bean protein concentrate (BPC) in feeds as a replacement for soy (SPC). Specifically, we focused on the hepatic transcriptome response to dietary BPC inclusion over a range including commercially relevant levels (e.g. 11-22%) to levels giving impaired performance (45 %). The present investigation provided a profile of the salmon hepatic response to BPC indicating that fish tolerated moderate substitution of dietary SPC with BPC with no evident negative effects on the hepatic physiology of the fish. The analysis of extreme levels of substitution provided insights into physiological mechanisms that are significantly altered providing the basis for further investigation and improvement.

Transcriptomic and metabolomic analysis reveal that fullerol improves drought tolerance in Brassica napus L.

Project description:The fullerenes, a kind of carbon nanoparticles, have potential for enhanced stress tolerance in plants. While the positive effects of polyhydroxy fullerene—fullerol on plants in response to drought at the physiological level have been documented, the molecular mechanism in Brassica napus are not entirely understood. In this study, exogenous fullerol was applied to the leaves of B. napus seedlings given drought. The leaves of B. napus seedlings in each treatment (sufficient water condition, drought, and drought combined with fullerol) were used to conduct the molecular mechanism using transcriptomic analysis.

RNA-Seq gives insights into genetic regulation of the drought-stress response in the cassava leaves

Project description:Cassava is a drought–resistant food crop in tropical and subtropical regions. Although cassava is a relatively drought-tolerant species, the development and yields are greatly affected by the adverse drought conditions. Information about molecular breeding will obtain by studying genetic regulatory mechanism. In this study, we demonstrate the drought-tolerant mechanisms in leaves of both cassava varieties(Xinxuan048 and KU50) by using RNA-Seq technique. 1,880 and 2,066 differentially expressed genes(DEGs) were induced by drought stress in leaves of KU50 and Xinxuan048, respectively. DEGs in the response to drought stress involve in many regulated pathways. ROS- and ABA-associated signaling pathways and photosynthesis-associated regulation are mainly elucidated. In addition, alternative splicing and ingle nucleotide polymorphism also involve in drought-stress responses in both cassava varieties, showing their important roles in response to drought stress in leaves. This study not only increases the understanding of physiological and molecular mechanisms to the drought response in cassava, but also lays a solid foundation on the breeding of drought-resistant varieties using molecular methods.

ACL1-HD-Zip IV complex revealed common mechanism in rice response to brown planthopper and drought. Being a small peptide, ACL1 might function through forming complex with other proteins. So that we searched the possible interacting proteins of ACL1 using the TurboID system.

Project description:Brown planthopper (BPH) is the most notorious insect pest to rice. Drought is the most commonly occurring global adversity. BPH infestation caused adaxially-rolled leaves and shrunk bulliform cells similar to drought. The bulliform-cell characteristic gene, ACL1, negatively regulated BPH resistance and drought tolerance, with decreased cuticular wax in ACL1-D, which resulted in quicker water losing. ACL1 was specifically expressed in epidermis. TurboID system and various biochemical assays revealed that ACL1 interacted with the epidermal-characteristic HD-Zip IV ROCs. ROC4 and ROC5 positively regulated BPH resistance and drought tolerance through modulating cuticular wax and bulliform cells respectively. Overexpression of ROC4 and ROC5 both rescued ACL1-D in various related phenotypes simultaneously. Moreover, ACL1 competed with ROC4 and ROC5 in homo-dimerization and hetero-dimerization. Altogether, we illustrated that ACL1-ROCs complex synergistically mediate drought tolerance and BPH resistance through regulating cuticular wax and bulliform cells in rice, a new mechanism which might facilitate BPH resistance breeding.
