Summary The cultivated Brassica species are the group of crops most closely related to Arabidopsis thaliana (Arabidopsis). They represent models for application in genomic information gained and provide an opportunity investigation polyploid genome formation evolution. scientific literature contains contradictory evidence dynamics evolution genomes. We aimed at overcoming inherent complexity genomes clarify effects polyploidy on microstructure specific segments genome. To do this, we have...
Summary Understanding the contribution of genetic background in fibre quality traits is important for development future cotton varieties with superior quality. We used Affymetrix microarray (Santa Clara, CA ) and Roche 454 GSFLX (Branford, CT comparative transcriptome analysis between two three inferior genotypes at six developmental stages. Microarray‐based variance ( ANOVA 89 microarrays encompassing five contrasting stages suggests that have a more pronounced effect on differentially...
Cotton leaf curl virus (CLCuV) is a serious pathogen causing disease and affecting the cotton production in major growing areas. The transgenic (Gossypium hirsutum cv. Coker 310) plants were developed by using βC1 gene antisense orientation driven Cauliflower mosaic virus-35S promoter nos (nopaline synthase) terminator mediated Agrobacterium tumefaciens transformation somatic embryogenesis system. Molecular confirmation of transformants was carried out polymerase chain reaction (PCR)...
Cotton is an important crop and its production affected by various disease pathogens. Monopartite begomovirus associated betasatellites cause leaf curl (CLCuD) in Northern India. In order to access the occurrence genetic variability of betasatellites, extensive field survey was conducted states Rajasthan, Punjab Haryana. We selected betasatellite sequence for analysis as they are reported severity variability. Based on observations, incidence ranged from 30% 80% during survey. Full genome...
Tospovirus has emerged as a serious viral pathogen for several crops including tomato. The tomato production is being severely affected worldwide by Tospovirus. Some reports have been published about the association of plant virus and development human disease either direct or indirect consumption. Resistance to this identified good source in wild species (Lycopersicum peruvianum). But introgression resistance genes into cultivated lines interspecific hybrid are hampered due incompatibility,...
Rhizobium sp. SIN-1, isolated in India from root nodules on the tropical legume Sesbania aculeata, also induces nitrogen-fixing roots of S. macrocarpa, speciosa, procumbens, punicea, rostrata, and Vigna unguiculata. Unlike Azorhizobium caulinodans, SIN-1 does not induce stem rostrata. The induced by develop exclusively at bases secondary roots. Electron microscopic studies mature nodule sections revealed rhizobia within intercellular spaces, indicating a 'crack entry' mechanism infection. is...
Leaf curl and yellow vein mosaic viral disease is the major constraint on okra (Abelmoschus esculentus L.) production in India. Amplified fragment sequence of DNA-β showed highest similarity 91.7% with Bhendi virus-Tamil Nadu (AJ308425, NC_003405) lowest 48.5% OKLCV (NC_004093), whereas coat protein specific amplified homology isolate Madurai, Haryana, Ludhiana 92% Mesta Bahraich virus (MYVMBV) (EU360303). The results obtained present study confirm that both diseases reported southern India...
A B S T R C severe leaf curl disease of Okra with high incidence and loss production was observed during field survey various locations Southern India, causal organism identified as Begomovirus its association confirmed by polymerase chain reaction (PCR) but also cloning sequencing amplified PCR products whitefly transmission. The DNA β Coat protein gene cloned sequenced. sequence data were assembled analyzed using the Bio-Edit (version 5.0.9). nucleotide sequences showed highest identities...
In this 7th contribution to the Fungal Systematics and Evolution series published by Sydowia, authors formally describe 14 species: Cantharomyces paschalis, Cryptandromyces pinguis, C. tricornis, Laboulbenia amblystomi (Laboulbeniales); Cortinarius squamosus, Entoloma brunneicoeruleum, E. callipygmaeum, minutigranulosum, perasprellum, pulchripes, tigrinum, timidum, violaceoserrulatum (Agaricales); Suillus quercinus (Boletales). The following new country records are reported: Crepidotus...
Banana is one of the important fruit crop in tropical and subtropical countries suffering from numerous diseases. The panama wilt caused by Fusarium oxysporum f.sp cubense most destructive disease banana. pathogen has different races with yield losses. Therefore we have studied on isolates about morphology growth behaviour media for further studies vitro as well vivo management this disease. After extensive survey districts, a total 14 isolated were collected varieties. These allowed to grow...
Panama wilt or Fusarium incited by oxysporum f. sp. cubense (Foc) is a major threat for banana cultivation and impacting symbolic economic losses worldwide. Previously Foc race 1 2 was detected in India which eventually spread monoculture of ‘Cavendish’ bananas resistant against these two races. Later on, another new TR4 to be group raised an alarming situation the global industry. In present study detailed survey conducted popular growing districts West Bengal, visualizing impact disease...
