To reduce the pesticide load in industrial plantings, it is necessary to use pathogen-resistant varieties when establishing orchards. The problem of obtaining stable, large-fruited, adaptive acute, since there are practically no genotypes existing assortment that combine a complex economically valuable traits with resistance diseases. isolation new genes wild forms and creation resistant fungal...

Interspecific hybridization is a common and important process that generates phenotypic novelty and can lead to hybrid speciation as well as to changes in gene expression. Using two different interspecific cotton (Gossypium) diploid hybrids, we show organ-specific, bidirectional allelic silencing at a heterozygous Adh locus, with alternate alleles being silenced in leaves and many floral organs...
