Abstract

Abstract: Prorocentrum triestinum BBW-02 strain, isolated from the Beibu Gulf of Guangxi province, was described on the basis of morphological characteristics and phylogenetic evolution relationship using light microscopy and molecular sequencing. The cells are lanceolate or heart-shaped, 20-26 μm long and 10-14 μm wide. The anterior spine is spearhead-shaped. The thichocysts of the surface are few, and mainly distribute around the margin irregularly. Two thichocysts distribute approximate symmetrically in the two-third of the theca. Homologous retrieval and system evolution analysis showed that P. triestinum BBW-02 was closely related to the other analysed P. triestinum. Compared with other species, P. triestinum BBW-02 had the most intimate relationship with P. gracile.
