The genome of Phytophthora infestans, the pathogen that triggered Irish potato famine in nineteenth century, has been sequenced. It remains a devastating pathogen, with late blight destroying crops worth billions dollars each year. Blight is difficult to control, part because it adapts so quickly genetically resistant strains. Comparison two other genomes shows rapid turnover and extensive expansion specific families secreted disease effector proteins, including many genes induced during...
Water deficit is a decisive challenge that tremendously affects maize physiological functions and productivity. Hence, it crucial to ameliorate its tolerance drought stress, in particular under abrupt climate change growing population. The present study aimed explore the influence of exogenously sprayed moringa seed extract (Moringa oleifera) α-tocopherol on physio-biochemical, morphological, yield attributes six diverse hybrids three irrigation levels poor-fertility sandy soil. applied...
The successful exploitation of germplasm banks, harbouring plant genetic resources indispensable for breeding, will depend on our ability to characterize their diversity. Vegetable Germplasm Bank Zaragoza (BGHZ) (Spain) holds an important Capsicum annuum collection, where most the Spanish pepper variability is represented, as well several accessions other domesticated and non-domesticated spp from all over five continents. In present work, a total 51 C. landraces (mainly Spain) nine species...
Drought is a major abiotic stress that greatly affects canola growth, production, and quality. Moreover, water scarcity projected to be more severe frequent as result of climate change, in particular arid environments. Thereupon, developing drought-tolerant high-yielding genotypes has become critical sustaining its production ensuring global food security with the continuing population growth. In present study, ten comprising six developed tissue-cultured genotypes, two exotic commercial...
Phytophthora crown rot, caused by capsici, is potentially the most destructive disease of pepper in Spain. Phenotypic and genetic diversity 16 P. capsici isolates collected from 11 farms northwest Spain was characterized based on virulence, mating type, sensitivity to metalaxyl, analysis using random amplified polymorphic DNA (RAPD) methods. Low variability observed among their metalaxyl response, with 87.5% being highly sensitive. No A2 type were detected. More found virulence assay,...
With 6 tables Abstract The Spanish Barley Core Collection comprises 159 landrace-derived inbred lines and 16 cultivars adapted to Southern European conditions. collection was screened for resistance powdery mildew (Blumeria graminis), scald (Rhynchosporium secalis), leaf rust (Puccinia hordei), net blotch (Pyrenophora teres f. teres), yellow dwarf virus (BYDV) mild mosaic (BaMMV). Resistance outstanding, with 58 presenting mean overall resistance, among them seven resistant all isolates...
Nitrogen is an essential element for maize growth, but excessive application can lead to various environmental and ecological issues, including water pollution, air greenhouse gas emissions, biodiversity loss. Hence, developing hybrids resilient low-N conditions vital sustainable agriculture, particularly in nitrogen-deficient soils. Combining ability genetic relationships among parental lines crucial breeding superior under diverse nitrogen levels. This study aimed assess the diversity of...
Reliable and sensitive quantification of Phytophthora capsici in pepper plants is crucial importance managing the multiple syndromes caused by this pathogen. A real-time polymerase chain reaction (PCR) assay was developed for determination P. tissues. DNA levels a highly virulent less isolate were measured different genotypes with varying degrees resistance. Using SYBR Green specific primers capsici, minimal amount pathogen quantified 10 pg. Pathogen recorded as early 8 h postinoculation....
Calcium is one of the most limiting factors for growth and reproduction peanut, which ultimately affects pod seed yields. A two-year field experiment was carried out to assess impact five calcium applications, including nano-calcium conventional forms, on growth, leaf nutrient content, yield traits, quality parameters three diverse peanut cultivars (Ismailia-1, Giza-5, Giza-6). The applied applications were sulfate, recommended commercial cultivation commonly referred as gypsum (coded Ca-1),...
ABSTRACT Spanish barley ( Hordeum vulgare L.) landraces exhibit good adaptation to Mediterranean conditions. This study aims at revealing the genetic control of heading date on a large population 464 doubled haploid lines from cross between line SBCC145 (a 6‐row with low vernalization requirement and agronomics) German cultivar Beatrix 2‐row, spring‐type, short stature, high yield, malting quality barley). The was evaluated using augmented designs in two field trials contrasting sowing...
Fifteen onion landraces from Galicia (northwest Spain) were characterised with a set of 25 microsatellite markers and the genetic variability harboured by this collection was compared surrounding diversity comparison representative panel European landraces. Twenty polymorphic allowing detection 121 alleles. Ninety-one these identified in Galician group (average 4.6 distinct alleles per locus) 9% total number recorded as unique specifically contributed northwest Spain. High values observed...
Inoculation of nonhost pepper ( Capsicum annuum ) plants with the tomato wilt pathogen, Fusarium oxysporum f.sp. lycopersici (FOL), caused no symptoms and fungus was not recovered from any part plant. FOL, however, partially protected subsequent infection Phytophthora capsici , Verticillium dahliae or Botrytis cinerea by significantly reducing percentage diseased appearance intensity symptoms. FOL did inhibit mycelial growth these pathogens in vitro . The protection induced against inhibited...
Abstract Inoculation with Fusarium oxysporum f. sp. lycopersici (FOL) protects pepper plants from subsequent infection Phytophthora capsici . In the present paper, level of local and systemic protection achieved by induced FOL was evaluated quantifying pathogen biomass using real‐time PCR. Differences in amount were found stems roots between FOL‐treated untreated plants, while could not be detected leaves plants. Five defence‐related genes coding for a PR‐1 protein, β‐1,3‐glucanase,...
With 1 figure and table Abstract An improved, efficient, reliable cost‐effective pyrosequencing protocol for single nucleotide polymorphism (SNP) genotyping in plants is described. Labelling of the PCR products, required single‐stranded assay, carried out a one‐step with universal biotinalyted M13 primer 19‐bp. A ratio : 10 tailed to 15‐μl reaction volume turned be best suited successful identification different alleles based on known SNPs. This technology allows SNP plant genomes loci...
In this work, the impact of pepper (Capsicum spp.) fruits morphology on their composition for health-promoting compounds was investigated. For that purpose, accessions from Ecuador, one hotspots in Capsicum’s origin, were analyzed ascorbic acid, polyphenols, capsaicinoids, and prevention cholesterol oxidation. Plant fruit phenomics assessed with conventional descriptors Tomato Analyzer digital traits. Significant differences among species revealed a large diversity within collection. The...
