Special Issue Information

Dear Colleagues,

Forests play important regional and global roles in the planet’s life, contributing to the mitigation of the impact of human activities. Among the forest ecosystem services, we can list the role of forests as sources of food, shelter, and energy; and in climate regulation, air purification, carbon sequestration, biomass production, etc. Additionally, forests play significant roles in forming and shaping the Earth’s crust, reducing soil erosion and wind and humidity regulation.

Forests are characterized by a great biodiversity of plant species of economic, conservative, and scientific interest. Invasive species, pollution, and climate change are some of the forest problems which lead to the loss of habitats and plant species. For this purpose, vegetative propagation is a strategy to counteract these adverse effects. Vegetative propagation technologies make it possible to obtain new plants starting from different vegetative plant parts. Somatic embryogenesis, the preferred method for in vitro plant propagation, may offer many advantages in clonal multiplication.

In this Special Issue of Forests, we explore the potential applications of Somatic Embryogenesis and Other Vegetative Propagation Technologies with the aim of understanding the new possibilities in the  restoration and conservation of forest biodiversity.

Potential topics include, but are not limited to:

  • Somatic embryogenesis;
  • Clonal propagation;
  • In vitro micropropagation;
  • In situ and ex situ conservation;
  • Synthetic seeds;
  • Sustainable forest management measures based on vegetative propagation;
  • Genomics, proteomics, and transcriptomics aspects of somatic embryogenesis and other vegetative propagation techniques.

Coconut palms (Cocos nucifera L.) are globally significant palms with both economic and cultural value. Despite the increasing demand for coconut products, production is decreasing globally due to palm senility, pests, and diseases. It has been estimated that over half of the world’s coconut palms need to be replaced immediately. The coconut industry has acknowledged that conventional propagation methods are unlikely to yield sufficient high-quality planting material. Therefore, coconut tissue culture is considered a potential solution to this problem. By using coconut tissue culture, a large number of plantlets can be obtained in a short period of time. In this study, the quality of explants and the development stage (visible shoot/non-visible shoot) of coconut used for micropropagation were examined. To our knowledge, little research has been undertaken on this aspect of coconut micropropagation. Our results indicated that tender coconut fruit exhibited an advantage over mature fruits. In addition, coconut plumule explants subjected to an extended storage of 15 days demonstrated enhanced development compared to those without storage. Notably, smaller embryos utilized as explants displayed superior callus formation compared to their larger counterparts. Finally, embryos possessing shoots exhibited improved callus initiation, albeit accompanied by a more pronounced browning effect. Further investigations are required to obtain more knowledge about the most suitable conditions for plumule explants that lead to optimal callus initiation. Full article

Human society is currently facing a growing demand for forest resources, which causes overexploitation and endangers biodiversity. In this regard, it is important to be aware that 10% of trees across the world are used in traditional and modern medicine. South America has the greatest diversity, with 40% of tree species in the world. The aim of our review consists of the assessment of the state of the art of micropropagation through somatic embryogenesis of representative medicinal trees in South America and of targeting the tree species that should be prioritized for conservation plans. From a total of 23,631 tree species from Central and South America, 31 are extinct, 7047 are threatened, and 1434 are possibly threatened. In this sense, in order to conserve them, various strategies are applied both in situ and ex situ. The application of in vitro multiplication protocols represents effective ways both in conservation and in the sustainable use of resources in order to obtain secondary metabolites of interest. Somatic embryogenesis is a well-known method in woody multiplication. According to the VOSviewer analyses, very few studies were available concerning aspects of somatic embryogenesis in medicinal trees. From the 10 representative species selected in our study, somatic embryogenesis protocols were established for 3 species, only for conservation purpose, not for secondary metabolites production. The development of protocols focused on obtaining secondary metabolites of medicinal trees will allow for the obtainment of valuable plant material as a non-invasive alternative. Full article

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. Full article
