Abstract:
As the major commercial source of natural rubber,Hevea brasiliensis attracts much attention.However,the heterozygous nature,long breeding cycle are strong limitations for conventional breeding.While genetic engineering,which can be used to widen the germplasm base and produce desirable agronomic traits quickly and efficiently,offers a viable alternative approach to complement traditional breeding.Comprehensive analysis indicates that in the past two decades,with calli derived from immature anther or integumental tissues of immature fruit as receptors,both biolistic and Agrobacterium-mediated transformation methods were employed for developping rubber genotypes with improved latex yield,tolerance to tapping panel dryness syndrome,producing high-value recombinant proteins,etc.Being recalcitrant to tissue culture,the transformation efficiency of Hevea is comparatively low,and the procedures are still needed to optimize.Finally,breeding objectives and strategies to improve transformation efficiency were also proposed in the review.
