Protoc. Here we generated RNA-seq data to compare the gene expression of symbiont-free (either nitrogen-starved or nitrogen-fed) and symbiosis-reconstituted hornworts (Fig. Read quality and adaptor trimming was done by fastp71 with the default setting. 132, jcs228551 (2019). Stomata may have originally been present . In A. agrestis Bonn, tandem repeats with a unit size over 30bp gave rise to only very short arrays, and these repeats do not show a clear spatial clustering (Supplementary Fig. Nevertheless, we found that in both A. agrestis (Oxford strain) and A. punctatus, one of the AMF symbiosis genes, RAM1, was upregulated when plants were nitrogen-starved (Fig. Genome assemblies of A. agrestis Oxford strain and A. punctatus were generated with the minimap2-miniasm assembler80 using only the nanopore reads.

Phylogenetic analyses were performed as for the ICE/SCRM case, but with LG selected as the best-fitting model.

Cultures of A. agrestis (Oxford and Bonn strains) and A. punctatus were all derived from a single spore and axenically propagated and maintained on either BCD67 or Hatchers68 media. To further corroborate this, we investigated patterns of intragenomic synteny in the three hornwort genomes, as well as the published M. polymorpha and P. patens genomes for comparison. In general, there was more collinearity between the liverwort and the moss than between the hornwort and the liverwort/moss genomes.

ML tree inference was done by IQ-TREE v.1.6.1 with 1,000 replicates of UltraFast Bootstraps109. We then used single-linkage clustering to construct gene families and estimate KS divergence using phylogenetic analysis by maximum likelihood (PAML)123 with the F3X4 model for each node in the gene family phylogenies.

The phylogenetic tree indicates that the hornwort LCIBs form a sister clade to the Klebsormidium nitens homologue (Fig. Some species of algae produce toxins that are lethal to fish, or render shellfish and finfish unsafe for consumption. 18, 116126 (2016). Microbiol. This implication is supported by the fact that only exogenous glucose, fructose or sucrose sustained dark nitrogen fixation in the A. punctatusN. 3c) similar to mosses and vascular plants, and the basic regulation may be shared across all stomatous lineages of land plants26. In particular, members of all extensively investigated gene families were checked for the presence of their domain structure either using InterPro125, Pfam126 or CCD127 to remove false positives and/or correct improperly predicted gene models. The search parameters were otherwise as default. In bryophytes, although mosses frequently harbour epiphytic cyanobacteria47, only hornworts and two liverwort species host cyanobacteria endophytically within specialized slime-filled cavities15,46. Due to this, the process of photosynthesis would not take place and plant will die due to excess water and no food. To identify genes that are differentially expressed in both A. agrestis Oxford and A. punctatus, we used the Orthofinder gene family classification results (see below) coupled with phylogenetic analysis if needed. For a discussion of the related protists, see the articles protozoan and protist. Because CO2 may diffuse into cells even when they are completely immersed in water, algae that live in marine environments do not require stomata to get the CO2 they require.

Hornworts also possess enzymes to synthesize strigolactones but genes involved in strigolactone signalling are absent. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Automated eukaryotic gene structure annotation using EVidenceModeler and the program to assemble spliced alignments. The Illumina libraries were prepared by BGI and sequenced on HiSeq4000.

Correspondence to Several genes involved in angiosperm meristem and stomatal function are conserved in Anthoceros and upregulated during sporophyte development, suggesting possible homologies at the genetic level. Altogether, our findings suggest a dynamic TAP family turnover in the early evolution of land plants with multiple independent losses in different bryophyte lineages.
