光合真核生物是通过异养宿主吞噬产氧光合原核生物（蓝细菌）而建立的。这个过程被称为初级内共生，产生了古质体纲，包括绿色植物、红藻和蓝绿藻。进一步的内共生事件产生了各种光养生物，它们可以积累α-1，4-/α-1，6-葡聚糖（包括淀粉）或β-1，3-/β-1，6-葡聚糖。本文综述了光养生物及其相关生物中贮藏葡聚糖，特别是淀粉的细胞内定位和分子形式的研究进展。
Phototrophic eukaryotes were established by the engulfment of oxygenic phototrophic prokaryotes (cyanobacteria) by a heterotrophic host. This process, called primary endosymbiosis, gave rise to the taxon Archaeplastida, which comprises green plants, rhodophytes and glaucophytes. Further rounds of endosymbiotic events produced a variety of phototrophic organisms, which could accumulate α-1,4-/α-1,6glucans (including starch) or β-1,3-/β-1,6-glucans. In this article, we review the recent progress in the study of the intracellular localization and molecular forms of storage glucan, especially starch, among the known phototrophs and related organisms.
