Recent studies reveal that relationships among the volvocine algae are more complex than was previously believed. Nevertheless, this group still appears to provide an unrivaled opportunity to analyze an evolutionary pathway leading from unicellularity (Chlamydomonas) to multicellularity with division of labor (Volvox). Significant progress in this regard was made in the past year when two genes playing key roles in Volvox cellular differentiation were cloned, and clues were uncovered regarding their mechanisms of action.
最近的研究表明，团藻目藻类之间的关系比之前认为的更为复杂。然而，这一群体似乎仍然提供了一个无与伦比的机会，来分析从单细胞（衣藻）到具有分工的多细胞（团藻）的进化路径。去年在这方面取得了重大进展，两个在团藻细胞分化中起关键作用的基因被克隆出来，并且发现了有关它们作用机制的线索。
