Relationships between growth, survival, physiology and behaviour — A multi-criteria approach to Haliotis tuberculata phenotypic traits
Provedor de dados: 5

Abalone growth rate is often identified among important traits to improve through selective breeding. However, the rapid success of some selective breeding plans has sometimes led to negative effects in some aquaculture species due to trade-offs. One of them is the loss of homeostasis of selected animals which results in the inability to resist the stress experienced during the rearing process. In this context, this study aimed to analyze the phenotypic relationships between growth, and physiological and behavioural traits in Haliotis tuberculata under stressful conditions. Eleven traits related to growth, immunity, reproduction and behaviour were recorded under laboratory conditions. A total of 120 adults from wild or farm origin were first monitored...

Signature d'expression de gènes, Marqueur prédictif de capacités de survie chez l'huître Crassostrea gigas
Provedor de dados: 5
Autores: Bachere, Evelyne; Degremont, Lionel; Piquemal, David; Roman, Bruno; Noguier, Florian.
Dans le contexte des mortalités massives d'huîtres Crassostrea gigas, les mécanismes moléculaires et les bases génétiques impliquées dans la capacité de survie des huîtres ont été explorées par des approches de génomique à très haut débit. Ces travaux se sont centrés dans un premier temps sur la survie à des infections par des Vibrio virulents pour lesquels des infections expérimentales étaient reproductibles et standardisées en laboratoire. Ces analyses ont conduit à la mise en évidence d'une série de gènes dont l’expression peut prédire la capacité des huîtres à survivre aux infections à vibrios (Rosa et al. 2012). Depuis 2013, les travaux ont permis la validation de la signature de survie qui a pu être corrélée avec les capacités de survie des huîtres...

Sources of black Sigatoka resistance in wild banana diploids
Provedor de dados: 94
Autores: Nascimento,Fernanda dos Santos; Sousa,Yan Moreira; Rocha,Anelita de Jesus; Ferreira,Claudia Fortes; Haddad,Fernando; Amorim,Edson Perito.
Abstract  Black Sigatoka (black leaf streak disease) is caused by the fungus Mycosphaerella fijiensisMorelet. This phytopathogen colonizes banana leaves, resulting in reduced photosynthesis and decreased productivity. Fungicide applications are useful to control black Sigatoka; however, they increase production costs and can have adverse environmental and health impacts. The cultivation of resistant cultivars is regarded as a more economically viable option. The objective of this study was to perform diploid phenotyping in a set of wild banana accessions to identify resistant genotypes. A total of 31 accessions (30 with AA genome and one with AB genome) were phenotyped based on the presence of disease symptoms using a scoring scale. The area under the...

ABSTRACT: The phenotypic and genetic analysis of apple (Malus × domestica Borkh) genotypes is essential for breeding species. Information on the morphology and genetic structure of apple offers significant help for germplasm maintenance and selection of suitable material to breed superior cultivars. This study shows the results of an investigation on the morphology and the genetic diversity for 19 apple cultivars, which are preserved in an ex situ collection in Naoussa, Central Macedonia, Greece. Information was recorded over a 5-year period for 47 traits describing plant morphology and phenotype, as well as leaf and fruit quality. Data were analyzed using the principal component analysis (PCA) method. The Euclidean distance metric and the Ward’s...

Identification of new sources of resistance to RHBV- rice hoja blanca virus

Abstract With the aim to find new sources of resistance to rice hoja blanca (white leaf) disease, transmitted by the insect Tagosodes orizicolus, 660 genotypes were evaluated under greenhouse and field conditions. Seven resistant genotypes were identified, and genomic studies were performed to demonstrate that the resistance in these sources is genetically different from that of Fedearroz 2000, which is currently the variety with the most resistance to hoja blanca. These new resistance sources constitute a resource that can be used to sustainably extend hoja blanca disease management throughout all of the rice-growing regions of tropical America. This is the first report of hoja blanca resistance in indica rice and different from that of Fedearroz 2000.

Ascertaining of Ug99-race specific genes in wheat genotypes assigned to stem rust resistance based on phenotypic and genotypic reaction
Provedor de dados: 111
Autores: Draz, Ibrahim Sobhy.
Five wheat genotypes including two commercial cultivars (Mist1 and Misr2) and three Ug99-race specific genes (Sr24, Sr25, and Sr31) were screened for stem rust resistance based on phenotypic and genotypic reaction. Based on phenotypic reaction, Sr24 (LcSr24Ag) and Sr31 (Seri-82) exhibited seeding and adult plant resistance while the wheat cultivars, Misr1 and Misr2 were susceptible. Sr25 Agatha (CI 14048)/9*LMPG-6 DK16 exhibited seedling resistance while showed susceptibility at adult plant stage. Based on genotypic reaction, DNA markers showed that gene Sr25 was only found to be present in Misr1 and Misr2 while Sr24 and Sr31 were absent in both cultivars. Although, virulence to Sr25 was detected. However, avirulence to Sr24 remains this gene as a suitable...

ABSTRACT High-throughput phenotyping using spectral reflectance measurements offers the potential to provide more information for making better-informed management decisions at the crop canopy level in real time. The aim of this study was to investigate the suitability of hyperspectral reflectance measurements of the crop canopy for the assessment of biomass, nitrogen concentration, nitrogen uptake, relative chlorophyll contents, and yield in 2 peanut cultivars, Giza 5 and Giza 6. Peanuts were grown under field conditions and subjected to 3 doses of nitrogen fertilizer with or without the application of 2 bio-fertilizers, Bradyrhizobium spp. or plant growth-promoting rhizobacteria. Simple linear regression of normalized difference spectral indices and...
