Abscisic Acid Custom Synthesis Service

Abscisic acid (ABA), as a natural plant hormone, plays a central role in regulating plant growth and development, stress responses, and fruit ripening. Compared to traditional plant extraction and chemical synthesis, microbial biosynthesis offers an economical, sustainable, and scalable alternative for ABA production. Lifeasible specializes in customized plant hormone synthesis, leveraging cutting-edge biosynthetic technologies to deliver high-purity, natural-configuration ABA and related intermediates through tailored production and services. Unlike conventional chemical synthesis, we are committed to using microbial cell factories to sustainably produce this plant hormone through green, efficient fermentation processes.

Why Choose Biosynthetic Abscisic Acid?

Abscisic acid (ABA) is one of the core hormones regulating plant growth, development, and stress responses, playing an irreplaceable role in enhancing agricultural yields, breeding for stress tolerance, and regulating seed dormancy. Chemical synthesis methods often face challenges such as difficult chiral control, numerous byproducts, and environmental unfriendliness. Biosynthetic approaches for abscisic acid production, particularly microbial fermentation, offer advantages such as mild reaction conditions, high stereoselectivity, and natural origin, providing reliable technical support for large-scale production of natural ABA.

In nature, ABA biosynthesis primarily follows two pathways. Our services are grounded in a deep understanding of these biosynthetic pathways.

• Direct pathway (C15 pathway). Synthesis proceeds directly from farnesyl pyrophosphate (FPP) as the immediate precursor.
• Indirect pathway (C40 pathway/carotenoid pathway). This is the primary pathway in higher plants. Starting with carotenoids, they undergo cleavage by the key enzyme 9-cis-epoxycarotenoid dioxygenase (NCED) to generate xanthene aldehyde, which is ultimately converted into ABA. Our microbial engineering strategy specifically mimics and optimizes this highly efficient natural pathway.

What Can We Offer for Abscisic Acid Synthesis?

We have established an advanced biosynthetic platform using recognized, safe-grade chassis cells, including Saccharomyces cerevisiae, Yarrowia lipolytica, and Escherichia coli. Through heterologous expression of fungal-derived ABA synthesis gene clusters, we achieve high-purity natural ABA production. The application of synthetic biology to artificially construct biosynthetic pathways for high-value natural products within microorganisms offers a more convenient and economical approach to abscisic acid synthesis and production.

• Host cell selection. Our commonly selected hosts include Saccharomyces cerevisiae, Yarrowia lipolytica, and Escherichia coli. As the most widely used microbial chassis, Saccharomyces cerevisiae, Yarrowia lipolytica, and Escherichia coli possess well-characterized genetic backgrounds and are operationally straightforward, making them ideal strains for industrial-scale production. In selecting chassis cells, we choose the most suitable host based on the characteristics of the natural product to achieve high-titer production. Since the ABA synthesis pathway involves multiple enzymes and is a complex, dynamically regulated process, different intracellular environments influence the efficient heterologous expression of key ABA synthesis enzymes.
• Key enzymatic screening and optimization. The ABA synthesis pathway involves crucial enzymes such as carotenoid cleaving enzymes (NCED) and aldehyde oxidases (AAO). We employ genetic engineering techniques to enhance the expression levels and activity of these enzymes.
• Coenzyme regulation. We optimize the supply of coenzymes, such as NADPH, to improve reaction efficiency.
• Precursor supply enhancement. We bolster ABA precursor availability by strengthening carotenoid synthesis pathways and regulating metabolic flux to minimize byproduct generation.
• Product efflux. We introduce plant-derived ABA transporters to promote ABA secretion and reduce intracellular toxicity.
