ABSTRACT.
Both linked and un-linked co-transformation can be used to overcome limitations of methods, such as re-transformation or sexual crossing of transgenic plants, to enable transfer of multiple genes to a single plant. Un-linked co-transformation can also facilitate the production of selectable marker-free transgenic plants. In this study, transgenic white clover plants were generated by Agrobacterium-mediated linked co-transformation using a single T-DNA of 9803 bp expressing: an isopentenyl transferase (IPT) gene for delayed leaf senescence under the control of an organ specific MYB32 promoter from Arabidopsis, a white clover nodule enhanced malate dehydrogenase (neMDH) gene for aluminium tolerance controlled by the endogenous Phosphate Transporter 1 (PT1) promoter, and the coat protein gene from Alfalfa Mosaic Virus (CP-AMV) controlled by the 35S promoter from Cauliflower Mosaic Virus. The selectable marker gene encoding hygromycin phosphotransferase (hph) was borne on a separate T-DNA. Forty independent transgenic events carrying the triple stack were generated, with estimated co-transformation efficiencies of 0.22 to 0.23%. Forty three percent of the events generated had a single insertion, while two events were selectable marker-free. Transcript abundance studies of the three transgenes of interest demonstrated the transcriptional competence of the inserted T-DNA. This study illustrates the feasibility of transferring multiple genes in a large single T-DNA into white clover by Agrobacterium-mediated co-transformation. Furthermore, observations of consistently delayed leaf senescence, statistically significant increases in TrneMDH transcript, and presence of CP-AMV transcript, support further analysis of these events for delayed leaf senescence under drought conditions, aluminium tolerance, and resistance to AMV.

ABSTRACT.
Due to the relevance of carcass and meat quality traits as breeding objectives of Texel as sire terminal breed, a progeny testing was implemented. In general, these difficult to measure traits have received less attention despite their economic relevance, particularly in more extensive environments in which sheep production is mainly located. Carcass traits were recorded on 424 female and male lambs: Hot Carcass Weight (HCW), most valuable cuts (French Rack, Shoulder and Leg weights), morphometrics traits (Carcass and Leg length, Leg Circumference) and GR (indicator of carcass fatness). Traits as Scanning weight, Rib Eye Area and Fat Thickness are routinely in vivo recorded in the genetic evaluation system and genetic parameters were estimated with 3.109 records by a multivariate analysis. Estimated Progeny Difference (EPD) for in vivo and post-mortem carcass traits was performed. Heritability estimates were of moderate to high magnitude, in agreement with other studies. Although results confirm that there is a scope for genetic improvement, these preliminary values should be interpreted with caution because of the low number of animals. All correlations between EPD were positive and favourable except for fatness traits that depend heavily on factors such as the production system and the target market. |
