چکیده

Buckwheat genus (Fagopyrum Mill.) is one of the aluminium tolerant taxonomic units of plants. The aim of the study was an evaluation of the aluminium (50 μM effect on phenolic accumulation in various parts of buckwheat plants (Fagopyrum esculentum Moench). Detection of increasing of total phenolic content, changes in flavonoid and anthocyanin content and phenylalanine ammonia-lyase activity (PAL) were revealed over a period of 10 days of exposure to aluminium. The most significant effects of aluminium treatment on phenolic compounds accumulation were total phenolic content increasing (by 27.2%) and PAL activity rising by 2.5 times observed in leaves tissues. Received data could be helpful to understand the aluminium tolerance principles and relationships of phenolic compounds to aluminium phytotoxicity.

Comparative Genotoxicity of Herbicide Ingredients Glyphosate and Atrazine on Root Meristem of Buckwheat (Fagopyrum esculentum Moench)

Herbicides have been extensively used in agriculture but people have not concerned about its adverse effects on plants and animals. The aim of the present study is to analyze the detrimental effects of two herbicides in Fagopyrum esculentum Moench (Variety: VL-7). The root tips were treated with four concentrations viz. 50, 100, 150 and 200 ppm of glyphosate and atrazine at room temperature for...

Differences in Aluminium Accumulation and Resistance between Genotypes of the Genus Fagopyrum

Aluminium (Al) toxicity is a major factor reducing crop productivity worldwide. There is a broad variation in intraand inter-specific Al resistance. Whereas the Al resistance mechanisms have generally been well explored in Al-excluding plant species, Al resistance through Al accumulation and Al tolerance is not yet well understood. Therefore, a set of 94 genotypes from three Fagopyrum species w...

Rapid genotyping with DNA micro-arrays for high-density linkage mapping and QTL mapping in common buckwheat (Fagopyrum esculentum Moench)

For genetic studies and genomics-assisted breeding, particularly of minor crops, a genotyping system that does not require a priori genomic information is preferable. Here, we demonstrated the potential of a novel array-based genotyping system for the rapid construction of high-density linkage map and quantitative trait loci (QTL) mapping. By using the system, we successfully constructed an acc...
