This study presents the status of ex situ and in situ conservation for the crop wild relatives of rice, potato, sweet potato, and finger millet in Brazil, and the subsequent germplasm collection expeditions. This research is part of a global initiative entitled "Adapting Agriculture to Climate Change: Collecting, Protecting, and Preparing Crop Wild Relatives" supported by the Global Crop Diversity Trust. Species of the primary, secondary, and tertiary gene pools with occurrences reported in Brazil were included: Oryza alta Swallen, O. grandiglumis (Döll) Prod., O. latifolia Desv., O. glumaepatula Steud., Eleusine tristachya (Lam.) Lam., E. indica (L.) Gaertn., Solanum commersonii Dunal, S. chacoense Bitter, Ipomoea grandifolia (Dammer) O?Donell, I. ramosissima (Poir.) Choisy, I. tiliacea (Willd.) Choisy, I. triloba L., and I. cynanchifolia Meisn. The status of the ex situ and in situ conservation of each taxon was assessed using the gap analysis methodology, and the results were used to plan 16 germplasm collection expeditions. Seeds of the collected material were evaluated for viability, and the protocols for seed germination and cryopreservation were tested. The final conservation score, resulting from the gap analysis and including the average of the ex situ and in situ scores, resulted in a classification of medium priority of conservation for all the species, with the exception of I. grandifolia (high priority). The total accessions collected (174) almost doubled the total accessions of these crop wild relatives incorporated in Embrapa's ex situ conservation system prior to 2015. In addition, accessions for practically absent species were collected for the ex situ conservation system, such as Ipomoea species, Eleusine indica, and Solanum chacoense. The methods used for dormancy breaking and low temperature conservation for the Oryza, Eleusine, and Ipomoea species were promising for the incorporation of accessions in the respective gene banks. The results show the importance of efforts to collect and conserve ex situ crop wild relatives in Brazil based on previous gap analysis. The complementarity with the in situ strategy also appears to be very promising in the country.

Abstract Genetic transformation is becoming routine for engineering specific traits in important clones of recalcitrant species such as Eucalyptus; however, the efficiency is still low for most species, so many researchers still use seeds instead of clones as initial explants. This work aimed to develop a genetic transformation protocol, based on a highly efficient in vitro organogenesis protocol, for an Eucalyptus urophylla clone selected in our breeding program. Plant growth regulators were evaluated for indirect organogenesis and rooting. In a two-step protocol, the combination of callus induction media supplemented with 0.5 lM thidiazuron + 0.5 lM naphthaleneacetic acid (NAA) and shoot induction media supplemented with 5.0 lM benzylaminopurine + 1.0 lM NAA allowed up to 85.6% shoot formation with more shoots per explants when compared with other concentrations. Transgenic plants expressing the uidA gene were obtained using Agrobacterium tumefaciens and selected for kanamycin resistance. A RAPD analysis was used to check for somaclonal variation. In tests using 11 RAPD primers, we did not observe somaclonal variation in the in vitro stages evaluated. |
