dc.description.abstract | Peanut (Arachis hypogaea) is a major oilseed crop and is widely cultivated in tropical and subtropical climate zone worldwide. Peanut belongs to the Papilionoid family with an atypical nodule developmental program. In particular, rhizobia enter through developmental cracks and lead to the formation of aeschynomenoid subtype determinate nodules. Peanut nodules are efficient nitrogen-fixers and form swollen bacteroid containing symbiosomes. The allotetraploid genome and recalcitrance to stable transformation used to be the major bottleneck for peanut biologists. Recent genome sequencing of peanut cultivar Tifrunner has opened up a huge opportunity for molecular research. A composite plant contains transformed roots with a non-transformed shoot. The composite plant-based approach has already proven to be a tool of choice for high throughput studies in root biology. The available protocols failed to generate efficient hairy root transformation in the genome sequenced cultivar Tifrunner. Here we describe an efficient hairy root transformation and composite plant generation protocol for the peanut cultivar Tifrunner. Our protocol generated ~92% plant regeneration efficiency with between 21.8% and 58.6% co-transformed root regeneration. We also show that this protocol can be efficiently used for protein localization, promoter GUS analysis, monitoring hormone response, and RNAi mediated knockdown of the genes using genome sequenced cultivar Tifrunner. | en_US |
