Characterization of chloroplast iridescence in Selaginella erythropus.

ABSTRACT: Iridescence in shade-dwelling plants has previously been described in only a few plant groups, and even fewer where the structural colour is produced by intracellular structures. In contrast with other Selaginella species, this work reports the first example in the genus of structural colour originating from modified chloroplasts. Characterization of these structures determines that they form one-dimensional photonic multilayers. The Selaginella bizonoplasts present an analogous structure to recently reported Begonia iridoplasts; however, unlike Begonia species that produce iridoplasts, this Selaginella species was not previously described as iridescent. This therefore raises the possibility of widespread but unobserved and uncharacterized photonic structures in plants.

The complete plastid genome of Selaginella erythropus (Selaginellaceae), a species with distinctive giant chloroplasts.

Project description:The plastid genome of the deep-shade plant Selaginella erythropus, which has highly unusual chloroplasts, was characterized using Illumina pair-end sequencing. This plastome is 140,151 bp in length with a large single-copy region (LSC) of 56,133 bp, a small single-copy region (SSC) of 61,268 bp, and two direct repeats (DRs) of 11,375 bp. The overall GC content is 50.68%, while those of LSC, SSC, and DR are 48.96%, 50.3%, and 55.96%, respectively. The plastome contains 102 genes, including 76 protein-coding, 15 tRNA (12 tRNA species), and 8 rRNA genes (4 rRNA species). The phylogenetic analysis shows that S. erythropus is closely related to S. moellendorffii and S. doederleinii. This result is consistent with the previous phylogenetic relationship inferred from multiple plastid and nuclear loci. However, only S. erythropus has the two-zoned giant chloroplast, the bizonoplast. The plastome provides an excellent reference for understanding the unique chloroplast differentiation in Selaginellaceae.

The complete chloroplast genome sequence of medicinal plant, Selaginella involvens.

Project description:Selaginella involvens distributed in East Asia region including China used as traditional medicine, which is an important medicinal plant for preventing and treating asthma. The complete chloroplast genome sequence of S. involvens was characterized from Illumina pair-end sequencing. The chloroplast genome of S. involvens was 126,340 bp in length, containing a large single-copy region (LSC) of 53,214 bp, a small single-copy region (SSC) of 47,561 bp, and two inverted repeat (IR) regions of 12,796 bp. The overall GC content is 38.70%, whereas the corresponding values of the LSC, SSC, and IR regions are 36.2%, 31.9%, and 43.2%, respectively. The genome contains 80 complete genes, including 61 protein-coding genes (45 protein-coding gene species), nine tRNA genes (six tRNA species), and eight rRNA genes (four rRNA species). The Neighbour-joining phylogenetic analysis showed that S. involvens and Selaginella tamariscina clustered together as sisters to other Salvia species.

Iridescence as Camouflage.

Project description:Iridescence is a striking and taxonomically widespread form of animal coloration [1], but that its intense and varying hues could function as concealment [2] rather than signaling seems completely counterintuitive. Here, we show that the color changeability of biological iridescence, produced by multilayer cuticle reflectors in jewel beetle (Sternocera aequisignata) wing cases, provides effective protection against predation by birds. Importantly, we also show that the most likely mechanism to explain this increase in survival is camouflage and not some other protective function, such as aposematism. In two field experiments using wild birds and humans, we measured both the "survival" and direct detectability of iridescent and non-iridescent beetle models and demonstrated that the iridescent treatment fared best in both experiments. We also show that an increased level of specular reflection (gloss) of the leaf background leads to an increase in the survival of all targets and, for detectability by humans, enhances the camouflage effect of iridescence. The latter suggests that some prey, particularly iridescent ones, can increase their chance of survival against visually hunting predators even further by choosing glossier backgrounds. Our study is the first to present direct empirical evidence that biological iridescence can work as a form of camouflage, providing an adaptive explanation for its taxonomically widespread occurrence.

Chloroplast RNA editing going extreme: more than 3400 events of C-to-U editing in the chloroplast transcriptome of the lycophyte Selaginella uncinata.

Project description:RNA editing in chloroplasts and mitochondria of land plants differs significantly in abundance. For example, some 200-500 sites of cytidine-to-uridine RNA editing exist in flowering plant mitochondria as opposed to only 30-50 such C-to-U editing events in their chloroplasts. In contrast, we predicted significantly more chloroplast RNA editing for the protein-coding genes in the available complete plastome sequences of two species of the spike moss genus Selaginella (Lycopodiophyta). To evaluate these predictions we investigated the Selaginella uncinata chloroplast transcriptome. Our exhaustive cDNA studies identified the extraordinary number of 3415 RNA-editing events, exclusively of the C-to-U type, in the 74 mRNAs encoding intact reading frames in the S. uncinata chloroplast. We find the overwhelming majority (61%) of the 428 silent editing events leaving codon meanings unaltered directly neighboring other editing events, possibly suggesting a sterically more flexible RNA-editing deaminase activity in Selaginella. No evidence of RNA editing was found for tRNAs or rRNAs but we identified a total of 74 editing sites in cDNA sequences of four group II introns (petBi6g2, petDi8g2, ycf3i124g2, and ycf3i354g2) retained in partially matured transcripts, which strongly contribute to improved base-pairing in the intron secondary structures as a likely prerequisite for their splicing.

Cloning and Functional Characterization of Two 4-Coumarate: CoA Ligase Genes from Selaginella moellendorffii.

Project description:Selaginella is an extant lycopodiophyte genus, which is representative of an ancient lineage of tracheophytes. The important evolutionary status makes it a valuable resource for the study of metabolic evolution in vascular plants. 4-coumarate: CoA ligase (4CL) is the pivotal enzyme that controls the flow of carbon through the phenylpropanoid metabolic pathway into the specific lignin, flavonoid, and wall-bound phenolics biosynthesis pathways. Although 4CLs have been extensively characterized in other vascular plants, little is known of their functions in Selaginella. Here, we isolated two 4CL genes (Sm4CL1 and Sm4CL2) from Selaginella moellendorffii. Based on the enzymatic activities of the recombinant proteins, both of these genes encoded bona fide 4CLs. The 4CL isoforms in S. moellendorffii have different activities: Sm4CL2 was more active than Sm4CL1. The enzymatic properties and gene expression patterns indicated that the 4CL genes have been conserved in the evolution of vascular plants.

Complete mitochondrial genome of Tringa erythropus (Charadriiformes: Scolopacidae).

Project description:The spotted redshank Tringa erythropus is a shorebird in the large bird family Scolopacidae. In this study, we sequenced and characterized its complete mitochondrial genome. The mitogenome is a circular DNA molecule of 16,683 bp in length, containing 13 protein-coding genes, 22 tRNA, 2 rRNA genes, and an AT-rich region. Its gene arrangement pattern is identical with typical bird species. Based on our data combined with the mitgenome DNA sequences of 12 Scolopacidae birds from GenBank, phylogenetic analysis indicated that T. erythropus, Arenaria interpres, and Eurynorhynchus pygmeus formed a group.
