in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Drought stress is an inevitable factor that disturbs the production of plants by altering morphological, physiological, biochemical, and molecular functions. Breeding for drought tolerance requires a complete understanding factors controlling stress-responsive pathways. The plant responds to adopting four mechanisms: avoidance, escape, tolerance, recovery. Traditional plant-breeding tools have ...

Background Image-based high-throughput phenotyping technologies have been rapidly developed in plant science recently and they provide a great potential to gain more valuable information than traditionally destructive methods. Predicting plant biomass is regarded as a key purpose for plant breeders and ecologist. However, it is a great challenge to find a predictive biomass model across experim...

Every year, thousands of purebred domestic dogs are bred by registered dog breeders. Yet, little is known about the rearing environment of these dogs, or the attitudes and priorities surrounding breeding practices of these dog breeders. The objective of this study was to explore some of the factors that dog breeders consider important for stock selection, with a particular emphasis on issues re...

Phenotyping is one of the most important processes in modern breeding, especially for maize, which an crop food, feeds, and industrial uses. Breeders invest considerable time identifying genotypes with high productivity stress tolerance. Plant spacing plays a critical role determining yield crops production settings to provide useful management information. In this study, we propose automated s...

Control over management of the world’s resources is increasingly contested because of economic, political and biophysical globalization, and increasing demands of a growing population of more than 6 billion. This has led to new interest in indigenous or traditional knowledge in many areas, including agriculture and plant breeding. Farmers were the first plant breeders, beginning with domesticat...

Increased use of intellectual property rights over plant germplasm has led to a complicated landscape for exchange among plant breeders. Our goal was to examine phenotypic and genotypic diversity present in commercially available carrot (Daucus carota L. var. sativus) germplasm in relation to the freedom to operate-the ability for plant breeders to access and use crop genetic diversity. A colle...

Plant breeding has been very successful in developing improved varieties using conventional tools and methodologies. Nowadays, the availability of genomic tools and resources is leading to a new revolution of plant breeding, as they facilitate the study of the genotype and its relationship with the phenotype, in particular for complex traits. Next Generation Sequencing (NGS) technologies are al...
