Summary: Sandalwood is highly valued for its fragrant heartwood and oil extraction, with santalols being the main components synthesized via the MVA pathway. The isolation and identification of SaMK and SaPMK genes in S. album, their high homology with genes from other plants, and their functional complementation in yeast indicate their crucial role in MVA biosynthesis. SaMK and SaPMK are constitutively expressed in various tissues and upregulated by methyl jasmonate, providing insights for further research on santalol biosynthesis.

Summary: Salinity is a detrimental stress for crop productivity, but can be overcome by growing high value tree species on saline lands. This study evaluated the effect of saline irrigation and different host species on the growth, physiological processes, and salinity tolerance of sandalwood. Results showed that sandalwood grown with Dalbergia sissoo, Azadirachta indica, and Melia dubia exhibited higher growth and tolerance under salinity stress. The growth parameters of sandalwood were negatively correlated with Na+ ion under salinity stress. Hosts Melia dubia, Dalbergia sissoo, and Azadirachta indica showed minimal decline in sandalwood growth and biomass under salinity stress. This study highlights the importance of host species in modulating sandalwood growth and its potential for cultivation in degraded saline soils.

Summary: This study investigated the role of 1-deoxy-D-xylulose-5-phosphate synthase (SaDXS) in the biosynthetic pathway of sandalwood sesquiterpenes in Santalum album L. The results showed that SaDXS1A/1B plays a crucial role in the synthesis of sandalwood sesquiterpenes and the biosynthesis of chlorophyll and carotenoids.

Summary: The natural populations of East Indian sandalwood (Santalum album L.) have greatly declined due to overexploitation in the past three decades. Santalum album L. seeds have poor germination, hindering nursery seedling production and plantation establishment. This study investigated the effects of hydro- and osmopriming on the germination and seedling performance of Santalum album L. The results showed that osmopriming with 5% PEG solutions for 2 days resulted in the highest germination (79%), which was 42% higher than the control. Longer priming times (6-8 days) had no effect or negatively affected germination and growth. Osmopriming can be recommended as a low-cost technology to enhance seed germination and seedling growth for quality planting material of Santalum album L.

Summary: An improved in vitro propagation system for Santalum album L. using meta-Topolin has been developed, which resulted in direct organogenesis and enhanced levels of amino acids and sugars in leaves. The combination of mT and NAA showed efficient shoot proliferation potential, while mT also led to favorable foliar structural developments.

Summary: Cytochrome P450 (CYP450s) are a large superfamily of enzymes that catalyze versatile reactions introducing oxygen into molecules. However, the current biotechnologies are hindered by limited oxygen availability. This review summarizes methods for CYP450s immobilization, activity detection, and synthesis of complex products, and introduces a novel approach using a gas-solid-liquid interface to overcome oxygen limitation.

Summary: AREB/ABF/ABI5 transcription factors play a role in regulating ABA-related gene expression and enhancing plant adaptability to environmental stress. Through genome-wide analysis, 10 SaAREB genes were identified in sandalwood, which were divided into five subfamilies. SaAREB genes encode unstable hydrophilic proteins and are localized in the nucleus. SaAREB1 responds to prolonged drought and is highly expressed in stems, while SaAREB3, SaAREB7, and SaAREB8 specifically respond to ABA treatment. These findings lay the foundation for further understanding the role of ABRE/ABF/ABI5 genes in santalol formation in Santalum album L.

Summary: This study investigated the role of miRNAs in regulating the expression of transcripts involved in santalol production mediated by the sesquiterpene biosynthesis pathway. The results showed that miRNAs can target certain transcripts in the pathway and negatively regulate their expression. This study provides crucial insight into the post-transcriptional regulation of sesquiterpene pathway genes in the genus Santalum and opens up new possibilities for metabolite engineering to enhance essential oil production in sandalwood.

Summary: Advancements in genome sequencing methods and assembly tools have significantly improved the contiguity and gap reduction in insect genome assemblies since the draft genome assemblies of the mountain pine beetle were published in 2013. The new assemblies have greatly increased contiguity, with 90% of the content now contained in 12 and 11 scaffolds for the female and male assemblies, respectively. Analysis of two chromosome regions revealed significant differentiation between northern and southern Canadian populations.
