With the method of BSA, a polymorphic band of 870 bp linked to T. matsutake was amplified, and the SCAR marker was developed from the polymorphic band by cloning, sequencing and designing primers. The SCAR marker only presented in the individuals of T. matsutake, thus, it can quickly and accurately identify T. matsutake and T. bakamatsutake at molecular level.展开更多
文摘RAPD analysis was adopted to identify the Tricholoma matsutake and T. bakamatsutake. With the method of BSA, a polymorphic band of 870 bp linked to T. matsutake was amplified, and the SCAR marker was developed from the polymorphic band by cloning, sequencing and designing primers. The SCAR marker only presented in the individuals of T. matsutake, thus, it can quickly and accurately identify T. matsutake and T. bakamatsutake at molecular level.
