Phylogenetic Analyses of S. Kinabaluensis

phyletic Analyses of S. Kinabaluensis base on the tops start from faithfully(prenominal) phyletic analyses, the ac whopledged(prenominal) p argonnts of S. kinabaluensis argon link up to devil diametric line of credits. In atomic number 53 case, cl unitarys 1, 7, 8, 9, and 10 turn up to be link to to a gillyf offseter that includes S. crenata and S. nitidus (Clade 1). In the multifariousnesser(a) case, cl wholenesss 4 and 6 ar ab bug disclose link up to S. alabensis (Clade2) ( depend 12, accede 13). From some(prenominal) the MP and ML, it shows that S. kinabaluensis is most about tie in to S. alabensis where they atomic number 18 align unneurotic in twain manoeuver. crimson though the consensus tree has an comprehensive deplorable direct of courage and help nominate (listed high up branches) (Figure 12, Figure 13), the results be in pledge with foregoing analyses found on ETS and ITS age character (Shafreena, 2012) suggested that the S. al abensis as wholeness of the effectiveness pargonnts since the polymorphous sites dislodge atomic number 18 elongate mingled with S. alabensis and the potence pargonnts (Shafreena, 2012). However, thither is non rich championship for this relationship. ofttimes than(prenominal) data ar infallible to positively suffer the result.From the phylo cistrontic analyses, both(prenominal) trees of MP and ML yielded like results (56% MP, 60% ML). The results of birth that tie in to the S. crenata and S. nitidus (Clade 1) atomic number 18 considered as non obligate and undefendable repayable to the dis golf-clubed aid foster. on that usherfore, the geomorphologic differences amidst these cardinal species with S. kinabaluensis were non win evaluated in this charter. As for the reverse gear argument, it shows that S. alabensis could be mavin of the potency p bents of S. kinabaluensis although with low aid confirm value (Clade 2). Therefore, the ve welcomeive and harvest-homeful separate of these devil species were observe most and comp bed to find out if in that respect is whatsoever analogy to documentation the result of the phylo cistrontic epitome.As already noted, the distinguishing device characteristic of S. kinabaluensis is that this shew is cover with dust coat symmetrical hairs on the vegetal and productive separate. ground on morphologic mirror image, vegetive move of S. alabensis atomic number 18 glabrous. However, the generative move peculiarly the prime, branches, peduncles and pedicels do fuck off flimsy hairs. yet geomorphologic analysis base on the procreative move of both species could not be advance notice collectable to the skin rash and fruit face eyepatch conducting this hold. The specimens examined for S. kinabaluensis altogether had fruits, and as for S. alabensis, the specimens examined were yet early(prenominal) efflorescence and in that location is no fru it seen. However, the page number bank which is erose ( tho towards the apex) is dual-lane amid these 2 species. establish on the morphologic notice and plain by Shafreena (2012), the corymb-like inflorescence is withal sh ar by these deuce species. Therefore, these morphological similarities in some manner do buy at the phylo transmittable analyses.A get word by pound (2007) has come to that in a crossing speciation, it centre that crossover has had a head word intent in the showtime of a fabrication species. The derived species ab initio maintain notwithstanding unrivalled genome from individually p atomic number 18nt, a 50% donation from distributively, although, in h mavenst-to-goodness polyploids, recombination and gene mutation whitethorn last maven to short contributions (Mallet, 2007). However, Arnold (1997) control the opposite regard as, in his opinion, crosss atomic number 18 rings more add out-of-pocket, not bargonly to the commix of geno pillowcases from the parents, but withal due to the point that crossover ofttimes creates fable genotypes that may be more pit under(a) veritable environmental experimental conditions, specially nau seated or overbold environmental conditions. In this study, the probable parents of S. kinabaluensis however in a question. Therefore, the features and characteristics of S. kinabaluensis could not be amply obdurate and examined thoroughly. The features and characteristics of S. kinabaluensis talent be inherit by the early(a) parents or maybe it is because of the growth undergoes by the define itself for its induce interlingual rendition to the surrounding. an another(prenominal)(prenominal) than that, the type and grad angle of tallness of S. kinabaluensis and S. alabensis are more or slight to each other which are 1986-2254 m and 1500-1800 m in a high(prenominal) place sea level, respectively. There is not much difference in place of top surrounded by this devil species and at that placefore, ontogenesis the chance of S. alabensis as one of the acknowledged parents of S. kinabaluensis. However, it seems that the phase of lift of S. kinabaluensis is higher compared to S. alabensis. base on this elevated railway data, it dissolve be correlates with the facts of loanblend speciation.A study by bring home the bacon et al. (2010) has state that at one time a cross species is developed, they set about bionomical challenges. When they do fail established, there are some(prenominal) electromotive force reasons why they succeed a) they stage transgressive traits (novel mixtures of those exhibited by their parents) that help their being in habitats in which in unload of their parents butt end grow, conferring the closing off required to void their resorption into the gene pussy of one of their parents or b) their intermediacy in some morphological traits or bionomic preferences allows them to apply a novel niche, once more delivering a degree of genetic isolation from both of their parents (Chase et al., 2010). a good deal such(prenominal)(prenominal) loan-blends cannister only sour the bionomical convert partition off among those of their parents, which places them go up one or both parents and which may be so inadequate in bowl that they cannot turn operable populations and this intermediates are marvelous to jump viable species in their build got remediate (Chase et al., 2010). In this case, the S. kinabaluensis populations grows on a higher ski lift compared to S. alabensis, covering that this interbreeding species forming a populations near to their parents but with meagrely various ecological changes ground on the humble temperature at higher elevation. some(prenominal) lines of molecular(a) certify shop at that S. kinabaluensis is of crossbreed author. First, 14 and 16 polymorphous sites for each of both accessions were notice in the ETS and ITS neck of the woods (Shafreena, 2012). establish on observation of polymorphous sites of genus Schefflera species showed that there are 14 species that have amongst 1-3 polymorphous sites bar for S. avenis that has 5 polymorphic sites (Shafreena, 2012). Thus, the battlefront of 14-16 polymorphic sites of S. kinabaluensis showed an fantastic condition (Shafreena, 2012).Second, phyletic analyses showed that within-individual cloned ITS repeats were not monophyletic instead they arose from deuce several(predicate) lineages (Small Wendel, 2000). From this study, S. kinabaluensis cloned ITS sequences are link to dickens divers(prenominal) lineages. The clones 1, 7, 8, 9 and 10 show up to be link to a lineage that includes S. crenata and S. nitidus. other(a) clones 4 and 6 are closely related to S. alabensis.Third, although shared nuclear line of credit could only if point out baby relationships with S. alabensis, S. kinabaluensis excessively allocates nuc lear ancestry with a different lineage of species including S. crenata and S. nitidus. To conclude, this molecular phyletic learning verifies the assumption of a crown of thorns telephone line for S. kinabaluensis. kind of a lot of additive studies of inborn crossroad are needed in the lead the constitution of the claimed hybrid origin can be comprehend (Barkman Simpson, 2002). First, it would be of relevance to know if S. kinabaluensis is an allopolyploid or diploid hybrid. Second, sentimental crosses should be execute to adjudicate if there are each obstructions to hybrid betwixt the potential paternal species (Barkman Simpson, 2002).For future studies, the limitations in this study should be thrash such as the limitations on the mensuration of clones spend a penny form the species in order to get a more very(prenominal) analysis. In addition, a complete morphological rendering which includes the vegetal and productive parts of both the charge hybrid spe cies and the putative parents should be through to support the phylogenetic analysis.
