“…Based on its seed coat pattern, C. olympica appears to have no close relatives among the investigated Campanula taxa. Earlier research reported that Campanulaceae seeds termed Type B are characterized by a reticulate surface, and sometimes a verruculate surface, on the reticulum (Murata 1992(Murata , 1995Antonelli 2008).…”

“…The family has a cosmopolitan distribution and is present in a wide array of habitats from tropical rain forest to tundra (Antonelli 2008). As currently circumscribed, the family is divided into five subfamilies: Campanuloideae Burnett, Lobeliodeaea Burnett, Nemacladoideae Lammers, Cyphioideae (A.DC) Walp and Cyphocarpoideae Miers (Lammers 1998).…”

Abstract:The seed coat morphology of 10 Campanula species from Turkey, 3 of which are endemic, was studied using scanning electron microscopy. Characteristics of the seeds and their surface morphology were described and compared. Two different types were described based on seed surface features. The Type 1 seed surface was characterized by a reticulate pattern; only C. olympica belonged to this type. The Type 2 seed surface had a striate testa and was the most common type. It included C. lyrata subsp. lyrata, C. rapunculoides L. subsp. rapunculoides, C. glomerata L. subsp. hispida, C. involucrata, C. saxonorum, C. persicifolia, C. latiloba subsp. latiloba, C. lactiflora and C. rapunculus L. var. lambertiana. However, some differences among these species were determined on the basis of their seed surface features at the microstructural level. These features were evaluated as possibly consistent parameters in the delimination of the Campanula taxa studied.

“…(17). Within the Lobeliaceae, Lobelia is the paraphyletic "core genus" from which other genera are segregates (18,19). Previous Southern blot analyses revealed that these plants have extensively rearranged plastomes, including "probing gaps" due to insertions and/or rapid sequence divergence relative to heterologous probes (20)(21)(22).…”

Why have some plants lost the organizational stability in plastid genomes (plastomes) that evolved in their algal ancestors? During the endosymbiotic transformation of a cyanobacterium into the eukaryotic plastid, most cyanobacterial genes were transferred to the nucleus or otherwise lost from the plastome, and the resulting plastome architecture in land plants confers organizational stability, as evidenced by the conserved gene order among bryophytes and lycophytes, whereas ferns, gymnosperms, and angiosperms share a single, 30-kb inversion. Although some additional gene losses have occurred, gene additions to angiosperm plastomes were previously unknown. Plastomes in the Campanulaceae sensu lato have incorporated dozens of large ORFs (putative proteincoding genes). These insertions apparently caused many of the 125+ large inversions now known in this small eudicot clade. This phylogenetically restricted phenomenon is not biogeographically localized, which indicates that these ORFs came from the nucleus or (less likely) a cryptic endosymbiont.foreign DNA | Cyphiaceae | Lobeliaceae | phylogeny T he extant diversity of algae and land plants chronicles the ongoing endosymbiotic transformation of a cyanobacterium into eukaryotic plastids (1), which are commonly known as chloroplasts because of their primary photosynthetic function. The early steps in plastome evolution involved the loss or transfer to the nucleus of most cyanobacterial genes, but an intron maturase (matK) and the two largest genes [ycf1 (an inner membrane translocon component); ref.2) and ycf2 (still of unknown function)] were incorporated before the origin of land plants (3). The characteristic plastome architecture of land plants (Fig.

“…These plants are robust tetraploids (2n = 28), often woody or pachycaul and up to 9 m tall, with sessile often apically rosulate leaves, terminal racemes or panicles of large unilabiate or sub-bilabiate flowers, and capsules producing numerous lenticular and commonly winged seeds with a striate-reticulate testa (Lammers 2011). Monophyly of the section is supported by several molecular phylogenies , 2006, Knox & Palmer 1998, Antonelli 2008. Although the African species have been the subject of numerous taxonomic studies (e.g., Bruce 1934, Hauman 1934, Hedberg 1957, Mabberley 1974, 1975a, b, Knox 1993, Knox & Kowal 1993, those from the remainder of the range have been accorded far less attention.…”

Detailed morphological study of specimens of Lobelia sect. Rhynchopetalum from Malesia revealed that this material could be divided into five species, all endemic to the region: L. philippinensis (three subspecies) and L. proctorii, endemic to the Philippines; L. sulawesiensis, sp. nov., endemic to Sulawesi; L. sumatrana, endemic to Sumatera; and L. eryliae, with one subspecies in the Philippines and the other in Sulawesi. A key is provided for distinguishing these taxa and each is described fully.
