AbstractNew traits that are useful for the cultivated sunflower can be received by applying classical breeding methods. A new form sunflower that is resistant to herbicides Pulsar and Express was obtained by hybridization between the sunflower mutant M-95-674 and the line HA 425. Test results from the period 2017–2019 confirm the resistance to both herbicides. This resistance can be transferred into other classical selected lines.

Much has been said about sunflower (Helianthus annuus L.) retrotransposons, representing the majority of the sunflower’s repetitive component. By contrast, class II transposons remained poorly described within this species, as they present low sequence conservation and are mostly lacking coding domains, making the identification and characterization of these transposable elements difficult. The transposable element Tetu1, is a non-autonomous CACTA-like element that has been detected in the coding region of a CYCLOIDEA (CYC) gene of a sunflower mutant, tubular ray flower (turf). Based on our knowledge of Tetu1, the publicly available genome of sunflower was fully scanned. A combination of bioinformatics analyses led to the discovery of 707 putative CACTA sequences: 84 elements with complete ends and 623 truncated elements. A detailed characterization of the identified elements allowed further classification into three subgroups of 347 elements on the base of their terminal repeat sequences. Only 39 encode a protein similar to known transposases (TPase), with 10 TPase sequences showing signals of activation. Finally, an analysis of the proximity of CACTA transposons to sunflower genes showed that the majority of CACTA elements are close to the nearest gene, whereas a relevant fraction resides within gene-encoding sequences, likely interfering with sunflower genome functionality and organization.
