Citation: N/A Interpretive Summary: A new species of the yeast genus Pichia is described. This species was recognized as new by comparing the genetic sequence of its ribosomal DNA gene with a database of yeast gene sequences developed at NCAUR. This new species is of scientific interest and its technological significance is being examined.
Technical Abstract: A description of Pichia lachancei, a new species of yeast that occurs in association with several Hawaiian plant species of the genera Tetraplasandra, Cheirodendron, and Clermontia. The new species is heterothallic and occurs in nature in the haploid as well as the diploid state. Upon conjugation of complementary mating types zygotes are formed which reproduce by budding as diploid cells. When placed on sporulation medium, four hat-shaped spores are produced which are rapidly released from the ascus. Phylogenetic analysis showed that P. lachancei is most closely related to Pichia rhodanensis and P. jadinii. The diploid type strain of P. lachancei, isolated from rotting bark of Tetraplasandra hawaiiensis on the island of Hawaii, is strain UCD-FST 79-9 = ATCC 00000 = CBS 00000 = NRRL Y-27008.
