Figure 1.

Developmental characteristics of H. catenoides and genome statistics of representative stramenopiles. Sketches of a subset of different stages of H. catenoides life cycle, adapted and redrawn from [6,14] showing: (i–iii) different views of zoospores (including magnification of tinselate flagellum i), (iv) germination stage of large spore, (v) primary enlargement or primary sporangium, (vi,vii) thallus development on substrate, (viii) unusual extensive branched thallus, which consists of separated sporangia at different stages of maturity (e.g. xii,xiv), connected by long, tubular, septate, hyaline and empty hyphae (x,xi), sometimes with enlargements without sporangia (e.g. ix). Zoospores may fail to swim coming to rest near exit tube (xiii). (b) Table of genome statistics for a range of different stramenopiles. Asterisk indicates k-mer estimation of genome size (column 2). All numbers are from the respective genome datasets (see electronic supplementary material, table S12). Numbers in italics (contigs, column 5) are inferred from the scaffolded data. CEGMA: C, complete; P, partial recovered gene models. BUSCO: C, complete; D, duplicated; F, fragmented; M, missing gene models.
