The objective of this study was to investigate whether a diet rich in legumes are associated with oxidative stress among type 2 diabetic patients. In a randomized, controlled, crossover clinical trial, 31 type 2 diabetic patients were randomly assigned to receive 2 diets, each for a period of 8 weeks: (1) The legume-free therapeutic lifestyle change (TLC) diet and (2) the legume-based TLC diet. Both diets were similar except that 2 servings of red meat were replaced by different types of legumes 3 days per week in the legume-based TLC diet...

Yellow Mosaic Disease caused by the begomovirus Mungbean Yellow Mosaic India Virus (MYMIV) severely affects many economically important legumes. Recent investigations in Vigna mungo - MYMIV incompatible interaction identified a MAPK homolog in the defense signaling pathway. An important branch of immunity involves phosphorylation by evolutionary conserved Mitogen-activated protein kinases (MAPK) that transduce signals of pathogen invasion to downstream molecules leading to diverse immune responses. However, most of the knowledge of MAPKs is derived from model crops, and functions of these versatile kinases are little explored in legumes...

BACKGROUND: Parasitoids are frequently used in biological control due to the fact that they are considered host specific and highly efficient at attacking their hosts. As they spend a significant part of their life cycle within their hosts, feeding habits and life history of their host can promote specialization via host-race formation (sequential radiation). The specialized host races from different hosts can vary morphologically, behaviorally and genetically. However, these variations are sometimes inconspicuous and require more powerful tools in order to detect variation such as geometric morphometrics analysis...

Ascochyta (Mycosphaerella) blight on cultivated peas is primarily caused by infection through asexual spores (pycnospores) of Mycosphaerella pinodes (Berk. et Blox.) Vestergren [recently renamed Peyronellaea pinodes (Berk. & A. Bloxam) Aveskamp, Gruyter & Verkley]. Using a model pathosystem involving Medicago truncatula and Mycosphaerella pinodes strain OMP-1, we examined the histology and ultrastructure of early infection events and fungal development including penetration by appressoria, vegetative growth of infection hyphae, and host responses...

Nitrogen-fixing rhizobia have established a symbiotic relationship with the legume family through more than 60 million years of evolution. Hundreds of legume host genes are involved in the SNF (symbiotic nitrogen fixation) process, such as recognition of the bacterial partners, nodulation signaling and nodule development, maintenance of highly efficient nitrogen fixation within nodules, regulation of nodule numbers, and nodule senescence. However, investigations of SNF-related gene functions and dissecting molecular mechanisms of the complicated signaling crosstalk on a genomic scale were significantly restricted by insufficient mutant resources of several representative model legumes...

Drought is one of the major abiotic stress conditions limiting crop growth and productivity. Glycosylation of proteins is very important post-translational modification that is involved in many physiological functions and biological pathways. To understand the involvement of N-glycoproteins in the mechanism of drought response in leaves of common bean, a proteomic approach using lectin affinity chromatography, SDS-PAGE and LC-MS/MS was applied. Quantification of N-glycoproteins was performed using MaxQuant with a label free quantification approach...

G Moyano, D Marco, D Knopoff, G Torres, C Turner
In the mutualism established between legumes and soil bacteria known as rhizobia, bacteria from soil infect plants roots and reproduce inside root nodules where they fix atmospheric N2 for plant nutrition, receiving carbohydrates in exchange. Host-plant sanctions against non N2 fixing, cheating bacterial symbionts have been proposed to act in the legume-Rhizobium symbiosis, to preserve the mutualistic relationship. Sanctions include decreased rhizobial survival in nodules occupied by cheating rhizobia. Previously, a simple population model experimentally based showed that the coexistence of fixing and cheating rhizobia strains commonly found in field conditions is possible, and that the inclusion of sanctions leads to the extinction of cheating strains in soil...

Reduction of seed dormancy mechanisms, allowing for rapid germination after planting, is a recurrent trait in domesticated plants, and can often be linked to changes in seed coat structure, in particular thinning. We report evidence for seed coat thinning between 2,000 BC and 1,200 BC, in southern Indian archaeological horsegram (Macrotyloma uniflorum), which it has been possible to document with high precision and non-destructively, through high resolution x-ray computed tomography using a synchrotron...

PREMISE OF THE STUDY: The Dialioideae is an early diverging clade of caesalpinioid legumes containing approximately 85 species in 17 genera. Dialioideae floral morphology is highly variable and may provide clues to caesalpinioid evolution, but a well-resolved phylogeny is needed. Here, we have carried out a comprehensive morphological study of 78 Dialioideae and four outgroup species. METHODS: For all available Dialioideae DNA samples, the plastid rpS16 and trnL introns were sequenced...

The aim of this work was to assess ten-year trends (1999-2010) of adherence to the Mediterranean dietary pattern (MDP) among the Balearic Islands' adult population. Two independent cross-sectional dietary surveys (1999-2000, n = 1200 and 2009-2010 n = 1388, including participants aged 16-65 years) were carried out in the Balearic Islands, Spain. Dietary habits were assessed by means of two 24 h diet recalls and a validated semi-quantitative food-frequency questionnaire that covers 145 food items. Adherence to the MDP was defined according to a score constructed considering the consumption of nine MDP characteristic components: high monounsaturated fatty acids:saturated fatty acids (MUFA:SFA) ratio, moderate ethanol consumption, high legumes, cereals and roots, fruits, vegetables, and fish consumption, and low consumption of meat and milk...

Lentil (Lens culinaris Medik.) is a diploid (2n = 2x = 14), self-pollinating, cool-season, grain legume that is cultivated worldwide and is highly valuable due to its high protein content. However, lentil production is constrained by many factors including biotic stresses, majority of which are fungal diseases such as ascochyta blight (AB), fusarium wilt, rust, stemphylium blight, anthracnose, and botrytis gray mold. Among various diseases, AB is a major -problem in many lentil-producing countries and can significantly reduce crop production...

Reducing the carbon footprint (CF) of crop production is an efficient way to mitigate climate change. Growing legume green manure (LGM) instead of summer fallow may achieve this goal by lowering synthetic nitrogen (N) fertilizer needs and replenishing the depleted soil carbon (C) pool. The Rothamsted Carbon (RothC) model was incorporated into the Life-Cycle Assessment (LCA) to evaluate the present and projected CFs of green manure-based wheat production systems in dryland agriculture on the Loess Plateau of China...

Symbiotic nitrogen fixation (SNF) between rhizobia and legumes requires metabolic coordination within specialized root organs called nodules. Nodules formed in the symbiosis between S. medicae and barrel medic (M. truncatula) are indeterminate, cylindrical, and contain spatially distinct developmental zones. Bacteria in the infection zone II (ZII), interzone II-III (IZ), and nitrogen fixation zone III (ZIII) represent different stages in the metabolic progression from free-living bacteria into nitrogen fixing bacteroids...

Population growth and climate change challenge our food and farming systems and provide arguments for an increased intensification of agriculture. A promising option is eco-functional intensification through organic farming, an approach based on using and enhancing internal natural resources and processes to secure and improve agricultural productivity, while minimizing negative environmental impacts. In this concept an active soil microbiota plays an important role for various soil based ecosystem services such as nutrient cycling, erosion control and pest and disease regulation...

The low FODMAP diet has been described, evaluated and found efficacious for the treatment of patients with irritable bowel syndrome (IBS) primarily in Western countries. The aim of this review was to address the applicability of this diet to South Asia. The high prevalence of IBS in South Asia and its associated effects of quality of life and economics warrants the introduction of efficacious therapies. The considerable heterogeneity of dietary patterns and methods of food preparation across South Asian countries and a paucity of food analysis limit precision in defining foods that are high or low in FODMAPs...

The Ca(2+) and Ca(2+)/calmodulin-dependent protein kinase (CCaMK) is an important effector protein of Ca(2+)/calmodulin-mediated signaling, and in legumes, it is a critical regulator of plant-rhizobia and mycorrhizal symbioses. CCaMK contains a kinase domain, a calmodulin-binding/autoinhibitory domain and a visinin-like domain. Previous studies revealed the presence of two phosphorylation sites, S343 and S344, in the calmodulin-binding domain. Mutations at these sites affected the kinase activity and downstream rhizobium and mycorrhizal symbioses, which highlighted the importance of these residues in regulating protein activity...

Maternal pre-pregnancy body mass index (BMI) and subsequent gestational weight gain (GWG) are strong predictors of maternal and infant outcomes; however the influence of dietary patterns on BMI-specific GWG is unclear. This study identifies patterns of habitual dietary intake in urban South African women and explores their associations with first trimester BMI and GWG. Habitual dietary intake of 538 pregnant women was assessed using a quantitative food-frequency questionnaire and dietary patterns were depicted via principle component analysis...

Allison B Frederick, David J Cutler, Judith L Fridovich-Keil
One of many vexing decisions faced by parents of an infant with classic galactosemia (CG) is how carefully to restrict non-dairy galactose from their growing child's diet. Until recently, many experts recommended vigorous lifelong dietary restriction of milk and all high-galactose dairy products as well as some non-dairy sources of galactose such as legumes and specific fruits and vegetables. Recently, experts have begun to relax their recommendations. The new recommendations, that restrict only high galactose dairy products, were made in the face of uncertainty, however, because no sufficiently powered study had been reported testing for possible association between rigor of non-dairy galactose restriction and severity of long-term outcomes in CG...

The mitogen-activated protein kinase (MAPK)-mediated phosphorylation cascade is a vital component of plant cellular signalling. Despite this, MAPK signalling cascade is less characterized in crop legumes. To fill this void, we present here a comprehensive phylogeny of MAPK kinases (MKKs) and MAPKs identified from 16 legume species belonging to genistoid (Lupinus angustifolius), dalbergioid (Arachis spp.), phaseoloid (Glycine max, Cajanus cajan, Phaseolus vulgaris, and Vigna spp.), and galegoid (Cicer arietinum, Lotus japonicus, Medicago truncatula, Pisum sativum, Trifolium spp...

BACKGROUND: Cowpea [Vigna unguiculata (L.) Walp.] is one of the most important legumes in tropical and semi-arid regions. However, there is relatively little genomic information available for genetic research on and breeding of cowpea. The objectives of this study were to analyse the cowpea transcriptome and develop genic molecular markers for future genetic studies of this genus. RESULTS: Approximately 54 million high-quality cDNA sequence reads were obtained from cowpea based on Illumina paired-end sequencing technology and were de novo assembled to generate 47,899 unigenes with an N50 length of 1534 bp...
