“…Morphological research emerges as a pivotal tool for swiftly assessing the genetic landscape through morphological traits, offering a precise analysis of variation. This method stands out as the most concise and direct approach for detecting genetic diversity, playing a crucial role in both interspeci c and intraspeci c classi cation [40,41]. In this study, the analysis of specimen features allowed for the identi cation of 14 characteristic Aquilaria species, including ve main cultivated species for agarwood production (Fig.…”

In the realm of Aquilaria classification and grading, a persistent market uncertainty persists, questioning whether the basis should be geographical distribution or biological origin. In this study, our goal is to shed light on the origin and diversification of the Aquilaria genera. We collected and analyzed a total of 320 specimens belonging to 25 species within the Aquilaria genera. Noteworthy findings include observed leaf similarities among three distinct species—A. yunnanensis, A. sinensis, and A. beccariana. Further results emphasize the effectiveness of matK molecular markers in differentiating Aquilaria species, leveraging 8 stable polymorphic loci. The integration of matK and trnL-trnF not only validates this efficacy but also streamlines the systematic categorization of 34 agarwood products. Delving into the evolutionary status and genetic background of Aquilaria, this study employs molecular clock analyses, revealing four distinct pedigrees: the Chinese pedigree 1 and 2, the Indonesian pedigree, and the Indochina pedigree, aligning with A. sinensis, A. malaccensis, and A. cumingiana, respectively. Notably, we identified A. sinensis and A. malacca as part of the youngest branch of Aquilaria evolution, with A. hirta emerging as the oldest member dating back to 6.78 million years ago. Furthermore, the research challenges previous assumptions by reevaluating G. walla, placing it at 5.75 million years ago, and suggesting its incorporation within the Aquilaria genus rather than considering it as an early divergent species.

“…Because achiote is a cross-pollinated plant, it does not show consistent yield in plantations; thus, vegetative propagation is a viable method to help solving this issue (JOSEPH; SIRIL; NAIR, 2011;PECH-HOIL et al, 2017). Commercial plantations can be based on the use of high-yield vegetatively-propagated plants (LOMBELLO; PINTO-MAGLIO, 2014;JOSEPH, 2013); however, high-yield clonal plantations are a viable alternative to those of seminal origin.…”

Bixa orellana L., also known as achiote, is a shrub native to tropical regions. It has been arousing the interest of the industrial sector due to the film that covers its seeds, which is rich in a reddish carotenoid called bixin. Although, traditionally, it is sexually propagated through seeds, this process can also take place in a vegetative manner. Given the economic and social relevance of this species, the aim of the current study is to assess both the vegetative and reproductive development of achiote plants, based on their propagation process, to help finding the best association between plant growth and early production. The experiment was conducted in a farm, in Porto Seguro City – Bahia State. Treatments were based on two genotypes (A and B), which were multiplied through asexual (plant cutting) and sexual (seeds) reproduction. The experimental design was based on randomized blocks, at 2x2 factorial arrangement, with 5 repetitions and 7 useful plants per plot. The following parameters were assessed at 59, 154, 284, 383, 497, 656 and 840 days after planting: incidence of flowers and/or capsules, stem diameter, plant height and canopy diameter. Collected data were compared to each other through Tukey’s test, at 5% probability level. Asexually propagated treatments were the first to start the reproduction stage, whereas sexually propagated treatments recorded higher vegetative development rate; no difference in vegetative development and in reproductive stage onset was observed between the investigated genotypes.

“…The major constituent (70 to 80% w/w) of dried seed arils that contributes to annatto, a coloring agent used in food, cosmetic, and textile dyes, is the carotenoid bixin (BXN; 9′Z-6,6′-diapocarotene-6,6′-dioate), whereas the water-soluble norbixin (NBX) is found in smaller amounts (Saha and Sinha 2012;Tupuna et al 2018). Natural cross-pollination and resulting heterozygosity make it impossible to propagate elite achiote clones or varieties by seeds, because progenies do not represent the original genotype (Rivera-Madrid et al 2006;Pech-Hoil et al 2017). Even though B. orellana can be vegetatively propagated by softwood or hardwood cuttings (Joseph et al 2011b(Joseph et al , 2012Lombello and Pinto-Maglio 2014), tissue culture and in vitro propagation of selected clones or varieties are the most effective ways to produce genetically uniform plant material (Siril and Joseph 2013) for agricultural and industrial purposes.…”

Bixa orellana L. (achiote) is a commercially important plant grown for its natural dye annatto, which is derived from the arils of seeds. Annatto, which contains the antioxidant bixin, is used in food, cosmetic, and textile industries as a natural colorant. Even though B. orellana can be propagated by seed, established tissue culture and in vitro propagation protocols exist for this plant. Organogeneses, both axillary and adventitious, as well as somatic embryogenesis, have been successfully induced from different explant sources, including cotyledons, hypocotyls, roots, stems, and leaves, and effective acclimatization protocols exist for regenerated plantlets. This present mini-review highlights the achievements in the tissue culture of achiote. In addition to using in vitro techniques for the clonal propagation of elite plants, knowledge from these protocols could be used to establish mass production systems, such as bioreactors, to facilitate year-round bixin harvest.
