How Synthetic Seeds Are Revolutionising the Agriculture Industry

Synthetic seeds, a revolutionary biotechnological innovation, offer genetic uniformity, cost-effective propagation, and versatile applications in agriculture, though their commercial use requires further research for full integration.

FREMONT, CA: Synthetic seeds are man-made structures containing somatic embryos, shoot buds, or meristematic tissue. These structures have the remarkable ability to mature into full-fledged plants when provided with the appropriate conditions, either within controlled laboratory settings or outside in the natural environment. Similar to traditional seeds, they are planted in soil and carry their reservoir of nutrients to facilitate growth. Initially, the production of synthetic seeds relied solely on somatic embryos, which significantly contributed to agricultural economic gains. However, progress in this field has broadened the array of materials employed for encapsulation.

Synthetic seeds are categorised into two distinct types based on the technique used to create them: desiccated and hydrated. Desiccated synthetic seeds involve the dehydration of somatic embryos using polyethylene glycol after encapsulation. Conversely, hydrated synthetic seeds are delicate and prone to damage from dehydration; therefore, they are encapsulated within hydrogel capsules to maintain their moisture content.

Tissue Types Used To Produce Artificial Seeds

Somatic embryos: Synthetic seeds are particularly well-suited for clonal propagation. Unlike traditional seeds, which arise from sexual recombination and give rise to genetically varied plants, somatic embryos originate from somatic or vegetative cells, guaranteeing genetic consistency. Somatic embryos are especially valuable for introducing desired traits through genetic engineering. Moreover, they are highly favoured in micropropagation due to their natural ability to generate roots and shoots without requiring specialised interventions.

Axillary shoot buds and Apical shoot tips: Axillary shoot buds and apical shoot tips are unique plant tissues with inherent growth potential. Situated at the junction between leaves and stems, axillary buds possess the capability to develop into branches or flowers. In contrast, apical shoot tips are positioned at the stem's apex and guide vertical growth. These tissues play a crucial role in horticulture, particularly in clonal propagation, as they produce exact genetic replicas of the parent plants.

After encapsulation, these tissues require specific cues to initiate root growth. Their significance lies in their efficiency in replicating desired plant traits, making them indispensable elements in modern agricultural and biotechnological practices.

Embryogenic tissues: Embryogenic tissues are comprised of clusters of cells that can evolve into embryos. These tissues hold great importance for clonal propagation and research on genetic transformation. Their value stems from their capability to ensure consistent genetic traits during plant reproduction, thereby facilitating the preservation and propagation of desired characteristics. However, nurturing embryogenic tissues necessitates significant labour and financial investments.

These specialised tissues play a significant role in biotechnology by providing a foundation for augmenting crop traits and producing genetically modified plants. Nonetheless, their cultivation demands meticulous care and allocation of resources due to their intricate nature and critical role in advanced plant breeding techniques.

Protocorms: Protocorms, crucial elements in orchid cultivation, represent early-stage structures that hold immense importance for overall plant growth. These foundational entities act as focal points for germination, originating from either seed embryos or tissue cultures. In the realm of orchid propagation, protocorms play an essential role in generating new plants, embodying a pivotal step in the process.

Moreover, the significance of protocorms extends to the realm of synthetic seed production, where they become encapsulated within sodium alginate gel. This encapsulation procedure forms the cornerstone for the development of synthetic seeds, thus contributing significantly to the progress of biotechnology and advanced plant breeding methods.

By participating in both natural and engineered propagation processes, protocorms assume a critical role in various facets of plant research, cultivation practices, and the formulation of innovative approaches aimed at promoting sustainable plant production.

Advantages Of Synthetic Seeds

Synthetic seeds pave a pathway for cultivating entirely novel plant lineages through biotechnological advancements. They maintain genetic uniformity among resulting plants, preserving desirable traits. Furthermore, these seeds simplify transportation, streamlining logistical considerations. Their ease of storage enhances their attractiveness, enabling convenient preservation without compromising viability.

A key advantage of synthetic seeds is their capacity to facilitate cost-effective, large-scale propagation of elite plant varieties. This potential for mass propagation is particularly advantageous in agriculture, enabling the swift production of high-quality crops. Additionally, synthetic seeds offer an economical alternative to conventional seeds, significantly reducing production expenses while upholding genetic consistency and desirable attributes in the resulting plants.

Applications Of Synthetic Seeds

Synthetic seeds offer a method of transporting propagules that are free from pathogens. They are especially valuable for maintaining the purity of male and female sterile plants used for hybrid seed production. Additionally, they streamline the propagation of transgenic plants, enabling efficient multiplication of genetically modified organisms.

Synthetic seeds are pivotal in expanding plant varieties that do not produce conventional seeds, including ornamental hybrids and polyploids. They are also useful for preserving endangered plant species, and cryopreserved synthetic seeds provide a means to safeguard germplasm.

By promoting genetic uniformity and preserving crop diversity, synthetic seeds contribute to sustainable agricultural practices. This technology has the potential to enhance food crops and establish environmentally friendly plantations.

Despite its versatile applications, the widespread commercial utilisation of synthetic seed technology remains largely unexplored and requires further scientific investigation. Some practitioners even introduce herbicide formulations during seed encapsulation, which enhances protection against pests and diseases. However, despite these expansive applications, the extensive adoption of synthetic seeds still requires comprehensive study by the scientific community.

Synthetic seeds represent a groundbreaking innovation in plant biotechnology with far-reaching implications. These artificial structures, including somatic embryos, shoot buds, and meristematic tissue, revolutionise clonal propagation, genetic engineering, and germplasm preservation. The inherent advantages, ranging from genetic uniformity to cost-effective large-scale propagation, underscore their potential to transform agriculture. Their applications range from hybrid seed production to conserving endangered species and enhancing food crops sustainably. However, while synthetic seeds exhibit diverse potential, their full commercial integration necessitates extensive research.
