“…Either incensole or serratol is indeed a marker for the distinction between B. sacra and B. carteri , as proposed by Woolley et al ., or a subpopulation of B. sacra exists in Oman which lacks the specific enzymes for the biosynthesis of these diterpene alcohols. B. sacra trees stand in relatively isolated locations along the coast and in the mountainous inland areas , and genetic exchange between the locations is highly limited. In a large study investigating genetic variance of B. sacra in Oman, the individual trees were shown to be genetically grouped according to their location and exhibited high interpopulation differentiation .…”

The genus Boswellia comprises many species which are famous for their production of frankincense, a fragrant gum resin. In the published literature, manifold studies on the volatiles and semivolatiles in individual samples of these gum resins exist, yet very few studies have investigated multiple samples. Contradictory results with regard to the volatile composition exist in literature. In this first part of the study, a large sample set (n = 46) of mostly commercially obtained gum resins and essential oils was investigated by solid-phase microextraction gas chromatography/mass spectrometry. A total of 216 compounds were identified or tentatively identified from the four commercially relevant species, namely B. sacra, B. serrata, B. papyrifera, and B. frereana, and the statistical evaluation of the resulting chemical profiles allowed a clear distinction between the species by their volatile profile. With only few exceptions, the designated species was found to be in accordance with the composition reported in reliable literature sources and detected in botanically identified samples. Chemotaxonomic marker substances were suggested to facilitate the differentiation of commercial gum resins or essential oils based on their volatile profile.

“…sacra is an endemic species growing only in Dhofar region of Oman [25–26]. The trees grow in desert-woodlands (Fig 1) with meager amounts of water and nutrient availability [27], whereas the domesticated trees are supplied with water [28]. In response to the incisions by the local people, the tree activates its defense mechanism by producing resin [28].…”

“…In response to the incisions by the local people, the tree activates its defense mechanism by producing resin [28]. The crystalline resin is used to create a fragrant smoke in homes and also sold in the market for income [26–27]. In addition to this, the tree has received much attention because of its medicinal uses in the Arabian region [29].…”

The First Chloroplast Genome Sequence of Boswellia sacra, a Resin-Producing Plant in Oman

et al. 2017

Boswellia sacra (Burseraceae), a keystone endemic species, is famous for the production of fragrant oleo-gum resin. However, the genetic make-up especially the genomic information about chloroplast is still unknown. Here, we described for the first time the chloroplast (cp) genome of B. sacra. The complete cp sequence revealed a circular genome of 160,543 bp size with 37.61% GC content. The cp genome is a typical quadripartite chloroplast structure with inverted repeats (IRs 26,763 bp) separated by small single copy (SSC; 18,962 bp) and large single copy (LSC; 88,055 bp) regions. De novo assembly and annotation showed the presence of 114 unique genes with 83 protein-coding regions. The phylogenetic analysis revealed that the B. sacra cp genome is closely related to the cp genome of Azadirachta indica and Citrus sinensis, while most of the syntenic differences were found in the non-coding regions. The pairwise distance among 76 shared genes of B. sacra and A. indica was highest for atpA, rpl2, rps12 and ycf1. The cp genome of B. sacra reveals a novel genome, which could be used for further studied to understand its diversity, taxonomy and phylogeny.

“…Indeed, while also not very genetically diverse, the "Wadi Dowkah Frankincense Park'' which was recognized as a World Heritage Site by UNESCO in 2000(World Heritage, 2016, currently has an ongoing program of germplasm conservation and restoration, and is "considered as the most representative Frankincense site in Oman" (Coppi et al, 2010). This park is at an elevation of 680 to 550 m above sea level, spans for 6 to 7 km 2 , and contains about 1,200 trees, some of which are centenarian, and noted as showing "an impressive branching architecture" as they branch very close to ground level (Raffaelli, 2006). Other more sparse, stunted, and scrubby B. sacra populations have been surveyed at elevations of around 18 m above sea level (Raffaelli et al, 2003).…”

“…Other more sparse, stunted, and scrubby B. sacra populations have been surveyed at elevations of around 18 m above sea level (Raffaelli et al, 2003). While other factors affect the health and regeneration of B. sacra populations such as humidity, geology and topography of surrounding mountains, weather patterns, presence of pollinators and human factors like cutting foliage for goat fodder, elevation plays a part in connection with all of these elements (Raffaelli, 2006).…”

Increasing Boswellia sacra seeds’ germination viability and genetic variability utilizing various methods

The medicinally and historically significant plant species Boswellia sacra, shown to be effective in addressing numerous illnesses and stabilizing desertification in arid areas, has been noted for having an extremely low germination rate. The low rate of genetic variation among wild stands, which is leading to a possible genetic bottleneck, is exacerbated by the common practice of vegetative propagation through tree cuttings in cultivated stands, which produces clones. Stimulation of seeds to germinate under various conditions at Kibbutz Ketura, Israel was attempted in order to increase genetic variability. Seeds were collected from three source locations and screened via sink tests to identify viable seeds as those that were heavy enough to sink in water. The greatest amount of viable seeds came from a tree in Kibbutz Naot Smadar, which was 400 m above sea level and had a higher germination rate (by a factor of four) than those from trees at elevations much closer to sea level. This conspicuous correlation is discussed as a reason for future research to further understand causes and ways of addressing the extraordinarily low regeneration rate of both wild and cultivated stands.
