| Abstract: | Key findings • Over 310 specimens of Chilean needle grass (CNG) and serrated tussock (ST) weeds sampled from eastern Australia are genetically distinguished from other tussock grasses based on DNA barcodes of the external transcribed spacer (ETS) gene. • ETS sequences unique to CNG or ST can be confidently targeted to develop rapid and portable genetic diagnostic methods to detect the two weeds. • Validation of the ETS DNA barcodes among CNG indicates potential presence of cryptic diversity in eastern Australia. |
