Opis:
The mechanism of floral mutation including double flowers in plant species can be explained by the ABCDE model which represents the relationship between MADS-box transcription factor genes and floral morphogenesis. The ornamental importance of Cyclamen led to the creation of double-flowered cultivars caused by the repression of AG-like gene expression in whorl 3. Modifications in these genes also influence the accumulation of different bioactive compounds depending on species and/or variety. In antiquity, cyclamen plants were recognized for their therapeutic qualities and later gained importance due to their content in saponins, which have been reported to exhibit anti-cancer, anti-inflammatory and antibacterial effects, and also to alleviate symptoms in acute rhinosinusitis patients. Furthermore, the extracts and isolated compounds are used as treatments in a wide range of diseases. In this review, we describe the transcription factors and their role in the development and ABCDE model formation of organs which led to the development of double-petal and fragrant varieties. Additionally, we describe the potential mechanisms of action underlying the therapeutic effects of saponin extracts against cancers and inflammatory disorders and their potential as a pharmacological agent in clinical studies.

Opis:
Pathogenicity and aggressiveness vs. wheat of 30 new Fusarium accessions, primarily F. graminearum, obtained  from random naturally infected grain samples of bread wheat, durum wheat and triticale collected across Romania,  phenotypically and by molecular tools has been investigated. A large variation of this trait, expressed as reduction of  coleoptiles length (% of control), in seedling stage, on average over three varieties, ranging from 2.1 to 30.9 % was  registered. Point field inoculations at anthesis of 90 Fusarium isolate x wheat varieties combinations, revealed also  the variability of several components of aggressiveness: severity (14.4-64.8%), AUDPC (104.9-527.1), and FDK 8.1-43.7%, respectively.Molecular techniques allowed identification of Fusarium species and the analysis of polymorphism within fungal  isolates. Moreover, the presence of TRI 5 gene involved in DON biosynthesis was detected in the majority of isolates.Similarity between records obtained in seedling and adult stage for the most aggressive of Fusarium isolates,  suggests that phenotypic selection in conjunction with molecular tools could be a reliable method to select the appropriate pathogen strains for breeding of resistance.
