Physio-agronomic performance of spring cultivars T. aestivum and T. spelta grown in organic farming system
One of the goals of organic crop production is to grow species which combinetraditional pro-healthy properties, innovative cultivation practices and harmonywith the environment. Among the ancient species the spring spelt is especiallypredisposed for organic farming. In comparison with common wheat spring spelthas a relatively short research history on physiological analysis of growth anddevelop...
متن کاملGene Family: Structure, Organization and Evolution
Gene families are considered as groups of homologous genes which they share very similar sequences and they may have identical functions. Members of gene families may be found in tandem repeats or interspersed through the genome. These sequences are copies of the ancestral genes which have underwent changes. The multiple copies of each gene in a family were constructed based on gene duplicati...
متن کاملEarly evolution of the T-box transcription factor family.
Developmental transcription factors are key players in animal multicellularity, being members of the T-box family that are among the most important. Until recently, T-box transcription factors were thought to be exclusively present in metazoans. Here, we report the presence of T-box genes in several nonmetazoan lineages, including ichthyosporeans, filastereans, and fungi. Our data confirm that ...
متن کاملRepeated evolution of crop theft in fungus-farming ambrosia beetles.
Ambrosia beetles, dominant wood degraders in the tropics, create tunnels in dead trees and employ gardens of symbiotic fungi to extract nutrients from wood. Specificity of the beetle-fungus relationship has rarely been examined, and simple vertical transmission of a specific fungal cultivar by each beetle species is often assumed in literature. We report repeated evolution of fungal crop steali...
