“…Thus, while the three taxa are obligate seeders, only C. verrucosa is a "post-fire obligate seeder"; C. glaucophylla and C. intratropica are "fire-intolerant obligate seeders". Similarly, their New Caledonian rainforest congener Callitris sulcata, which has not evolved with fire and is poorly adapted to it, can only regenerate from seed and can also be considered a 'fire-intolerant obligate seeder' [16]. Highlighting the fact that plant responses are seldom absolute, we note that some Callitris species are able to very weakly resprout after fire (Figure 1d-e); it is unknown why species in this clade that grow in fire-prone environments have not evolved more robust aerial resprouting.…”

Developing standardised classification of post-fire responses is essential for globally consistent comparisons of woody vegetation communities. Existing classification systems are based on responses of species growing in fire-prone environments. To accommodate species that occur in rarely burnt environments, we have suggested some important points of clarification to earlier schemes categorizing post-fire responses. We have illustrated this approach using several Australasian conifer species as examples of pyrophobic species. In particular, we suggest using the term “obligate seeder” for the general category of plants that rely on seed to reproduce, and qualifying this to “post-fire obligate seeder” for the narrower category of species with populations that recover from canopy fire only by seeding; the species are typically fire-cued, with large aerial or soil seed banks that germinate profusely following a fire, and grow and reproduce rapidly in order to renew the seed bank before the next fire.

“…For example, C. sulcata is on the IUCN Red List as endangered (http://dx.doi.org/10.2305/IUCN.UK.2010.RLTS.T30993A9590761.en); the known populations are distributed in small regions of the southern province of New Caledonia (Haverkamp et al, 2015). Thus, only small juveniles grown in gardens as back-up populations for ex situ conservation were available for chloroplast genome sequencing.…”

“…The successful application of our chloroplast enrichment protocol to small amounts of fresh plant material means that it can be used to study endangered and extremely small species; less than 1.0 g of material is required. For example, C. sulcata is on the IUCN Red List as endangered ( http://dx.doi.org/10.2305/IUCN.UK.2010.RLTS.T30993A9590761.en ); the known populations are distributed in small regions of the southern province of New Caledonia ( Haverkamp et al, 2015 ).

Premise of the study:High-throughput sequencing of genomic DNA can recover complete chloroplast genome sequences, but the sequence data are usually dominated by sequences from nuclear/mitochondrial genomes. To overcome this deficiency, a simple enrichment method for chloroplast DNA from small amounts of plant tissue was tested for eight plant species including a gymnosperm and various angiosperms.Methods:Chloroplasts were enriched using a high-salt isolation buffer without any step gradient procedures, and enriched chloroplast DNA was sequenced by multiplexed high-throughput sequencing.Results:Using this simple method, significant enrichment of chloroplast DNA-derived reads was attained, allowing deep sequencing of chloroplast genomes. As an example, the chloroplast genome of the conifer Callitris sulcata was assembled, from which polymorphic microsatellite loci were isolated successfully.Discussion:This chloroplast enrichment method from small amounts of plant tissue will be particularly useful for studies that use sequencers with relatively small throughput and that cannot use large amounts of tissue (e.g., for endangered species).
