From: TIR-NBS-LRR genes are rare in monocots: evidence from diverse monocot orders
Taxa included in this study. The tree shows the ten orders and one family that form the monocots [19]. The broad relationships between the monocots and other land plants are shown. Groups marked with an asterisk (*) show where TIR-type NBS sequences have been confirmed. The status of TIR-type NBS sequences in Poales is unclear (*?) since these sequences are generally considered absent from Poales, but have been found in one study [14]. Monocot orders in green correspond to NBS sequences obtained in this study by degenerate PCR while those in blue show where sequences in this study were obtained from databases. TIR-type NBS sequences found or not found in this study: + or -
