“…In coconut palm, SE involves three main stages; the induction of embryogenic callus (cell cycle, dedifferentiation, and totipotency), somatic embryo development (meristem maintenance), and plantlet maturation [51]. The stimulation of cell proliferation, acquisition of embryogenic cell competence, and induction of somatic embryos undergo a series of development events [25].…”

The coconut palm (Cocos nucifera L.) is a perennial, cross-pollinated, oil-bearing tropical forest tree. Recently, the demand for coconut goods has surged to 5 to 10 times its former value; however, coconut production is in jeopardy. Coconut senility is one of the most apparent factors that influence productivity. Adequate replanting is urgently required to maintain the growing demand for coconut products. However, coconut palm mass replanting might not be possible with traditional approaches. To overcome this snag, micropropagation via somatic embryogenesis (SE) has enormous potential for proficient clonal propagation in the coconut palm. During SE, the stimulation of cell proliferation, acquisition of embryogenic cell competence, and induction of somatic embryos undergo a series of developmental events. This phenomenon requires regulation in gene expression patterns and the activation of specific signaling pathways. This review summarizes gene regulatory mechanisms involved in the cell cycle, dedifferentiation, totipotency, embryo initiation, and meristem development during somatic embryo formation. Plant hormonal signal transduction is also highlighted during the formation of SE in coconut.

“…Aplicações, incluindo o uso do método para a coleta de germoplasma, a conservação (criopreservação) e a disseminação do germoplasma de elite, e o início da propagação clonal (via embriogênese somática) também são importantes (BIDDLE et al, 2020). Assim, aplicações para conservação e movimentação segura de germoplasma, propagação clonal, valorização de produtos alimentícios e promoção de meios de vida sustentáveis (ADKINS et al, 2020) são importantes para a realização de cultivos adequados, pois o melhoramento genético para características desejáveis é identificado como vital para melhorar a produtividade de coco em todo o mundo e as ferramentas biotecnológicas (Figura 2) são muito importantes para superar as deficiências das abordagens tradicionais (BANDUPRIYA et al, 2020).…”

“…Sesame has also been used as a snack food by adding honey and other minor sugar sources and is a major ingredient in hummus, a dip product resulting from chickpea flour and sesame paste [ 9 ]. Sesame oil, on the other hand, attracts significantly value for its health benefits [ 2 , 10 ], such as the prevention of obesity [ 11 , 12 ], coronary heart diseases [ 13 , 14 , 15 ], colon cancer [ 11 , 16 , 17 ], and gastrointestinal disorders [ 18 , 19 ] and reduction of the risk of developing diabetes [ 17 , 18 , 20 ]. Consequently, the inclusion of sesame in human diets may provide significant health benefits.…”

Sesame is an emerging crop of interest in Australia and has attracted widespread interest due to the health-benefitting properties of its bioactive compounds, including fatty acids, lignans, and polyphenols. This study aimed to investigate the impact of drought stress on these bioactive compounds, using eleven cultivars of black sesame seeds grown in Australia. Specific varieties responded positively to water deficit (WD) conditions, showing increased levels of TPC, FRAP, CUPRAC, and lignans. Varieties 1, 4, 7, and 12 showed significantly increased FRAP values ranging from 158.02 ± 10.43 to 195.22 ± 9.63 mg TE/100 g DW in the WD treatment compared to the well-watered (WW) treatment, whereas varieties 7, 10, 12, 13, and 18 demonstrated the highest CUPRAC values of all varieties (2584.86 ± 99.68–2969.56 ± 159.72 mg TE/100 g) across both WW and WD conditions, with no significant variations between irrigation regimes. Moreover, lignan contents (sesamin and sesamolin) were higher in varieties 1, 2, 5, and 8 grown in WD conditions. Compared to the optimal unsaturated to saturated fatty acid ratio (Σ UFA/Σ SFA ratio) of 0.45, all sesame genotypes showed superior ratios (ranging between 1.86 and 2.34). Moreover, the ω-6/ω-3 PUFA ratio varied from 33.7–65.5, with lower ratios in varieties 2, 4, 5, 8, and 18 under WD conditions. The high levels of phenolic compounds and healthy fats suggest the potential of black sesame to be incorporated into diets as a functional food. Furthermore, the enhanced phytochemistry of these cultivars in WD conditions is promising for widespread adoption. However, larger trial studies to confirm these findings across different geographic locations and seasons are warranted.
