Conteúdo: |
Sugarcane (Saccharum spp.) is a monocotyledonous semi-perennial C4 grass of the Poaceae family. Its capacity to accumulate high content of sucrose and biomass makes it one of the most important crops for sugar and biofuel production. Conventional methods of sugarcane breeding have shown several limitations due to its complex polyploid and aneuploid genome. However, improvement by biotechnological engineering is currently the most promising alternative to introduce economically important traits. In this work, we present an improved protocol for Agrobacterium tumefaciens-mediated transformation of commercial sugarcane hybrids using immature top stalk-derived embryogenic callus cultures. The callus cultures are transformed with preconditioned A. tumefaciens carrying a binary vector that encodes expression cassettes for
a gene of interest and the bialaphos resistance gene (bar confers resistance to glufosinate-ammonium herbicide). This protocol has been used to successfully transform a commercial sugarcane cultivar, SP80-3280, highlighting: (i) reduced recalcitrance and oxidation; (ii) high yield of embryogenic callus; (iii) improved selection; and (iv) shoot regeneration and rooting of the transformed plants. Altogether, these improvements generated a transformation efficiency of 2.2%. This protocol provides a reliable tool for a routine procedure for sugarcane improvement by genetic engineering. |
