Opis:
Somatic embryogenesis (SE) of conifers for clonal propagation has emerged from its earliest beginnings in 1980 to become an integral component of tree improvement strategies. With its capacity for long-term germplasm preservation and scale-up technologies,it is seen to be the preferred avenue to accelerate selection and operational deployment of value-added genotypes. At present,programs for numerous species from the Pinaceae family are underway worldwide,with activities ranging from selection trials to pilot production for plantation forestry. This paper will provide a review of current efforts in conifer SE including cryopreservation,commercialization and deployment strategies,and transgenics. A discussion of challenges and issues is directed at genetic fidelity, intellectual property and future needs.

Opis:
Somatic embryogenesis is the latest, and potentially the most efficient, method for the vegetative micropropagation of plants. Over the past three decades, numerous laboratory studies have investigated somatic embryogenesis of forest trees, yielding positive results for a number of economically important tree species. The first test trials were run and plantations were planted with interior spruce in the 90s by CellFor Inc. (Canada). However, at the beginning of the XXI century, the program to produce spruce and Douglas fir somatic seedlings was stopped for economic reasons. Thus, currently no operational program is ongoing except on a small scale in New Brunswick. In order to integrate somatic embryogenesis technology into operational reforestation programs, the production costs of forest tree somatic seedlings needs to be reduced, and the awareness of foresters and forest landowners that the material obtained through somatic embryogenesis is valuable needs to be increased. This awareness would enable implementation of this technology on a large scale for production and forest management throughout Europe including Poland. In this review, the importance of somatic embryogenesis in scientific research and in global and European forestry is presented. Our main aims are to provide basic information on the challenges in researching somatic embryogenesis of forest trees and to raise interest in this tree propagation technique in both scientists and foresters.

Opis:
The discovery of conifer somatic embryogenesis (SE) and the subsequent development of SE protocols for a range of genera and species have opened new research opportunities to forest biotechnologists and a means towards mass clonal propagation for the forest industry. This paper provides a general description of the conifer SE process, followed by a review of protocols developed specifically for several conifer species in the Pinaceae family for which production of somatic trees has been demonstrated. Additionally, future research needs, including approaches for developing markers to optimize SE process and the production of high quality embryos, are discussed.

Opis:
Embryogenic cultures of plants are exposed to various stress factors both in vitro and during cryostorage. In order to safely include the plant material obtained by somatic embryogenesis in combination with cryopreservation for breeding programs, it is necessary to monitor its genetic stability. The aim of the present study was the assessment of somaclonal variation in plant material obtained from embryogenic cultures of Picea abies (L.) Karst. and P. omorika (Pančić) Purk. maintained in vitro or stored in liquid nitrogen by the pregrowth-dehydration method. The analysis of genetic conformity with using microsatellite markers was performed on cotyledonary somatic embryos (CSE), germinating somatic embryos (GSE) and somatic seedlings (SS), obtained from tissues maintained in vitro or from recovered embryogenic tissues (ETc) and CSE obtained after cryopreservation. The analysis revealed changes in the DNA of somatic embryogenesis-derived plant material of both Picea spp. They were found in plant material from 8 out of 10 tested embryogenic lines of P. abies and in 10 out of 19 embryogenic lines of P. omorika after in vitro culture. Changes were also detected in plant material obtained after cryopreservation. Somaclonal variation was observed in ETc and CSE of P. omorika and at ETv stage of P. abies. However, most of the changes were induced at the stage of somatic embryogenesis initiation. These results confirm the need for monitoring the genetic stability of plants obtained by somatic embryogenesis and after cryopreservation for both spruce species.

Opis:
The studies were carried out on seed explants (mature zygotic embryos) of four spruce species: Picea omorika (Pancić) Purk., P. pungens ‘Glauca' Beisnn., P. breweriana S. Watson and P. abies (L.) Karst. The explants required darkness during the induction of embryogenic tissue. Temporary exposure of explants to light did not increase their embryogenic capacity. It was observed that the temperature of 25°C was the optimal for embryogenic tissue induction from mature zygotic embryos of Picea omorika. Cold treatment at 4°C during one week improved embryogenic tissue initiation in the explants of P. pungens ‘Glauca'. Seed explants of Picea omorika produced embryogenic tissue on medium lacking glutamine. Only explants of Picea abies and P. omorika showed embryogenic tissue formation. For effective proliferation of embryogenic tissue in Picea abies and P. omorika it was necessary to supply the medium with 2,4-D (4.5-9 μM) and BA (2.25 μM). Two of three analized lines showed that ABA promote somatic embryo maturation, at the ABA concentration 20 μM in the medium.

Opis:
The objective of the presented study was to compare the effect of osmotic stress, induced by various concentrations of polyethylene glycol (PEG) MW 4000, on the development, maturation, and conversion of somatic embryos of Picea abies (model species) and P. omorika (endemic species) into somatic seedlings. Embryogenic tissue (ET) of P. abies (line A and B) and P. omorika were incubated on a maturation medium with 20 μM abscisic acid (ABA), 1 μM indole-3-butyric acid (IBA) and PEG 4000 at 0, 5, and 7.5%. After 5 weeks, the number of somatic embryos produced, and the number of cotyledonary somatic embryos per 1 gram of ET, was assessed. Cotyledonary somatic embryos were selected and transferred to a Margara germination medium for two months. Their growth, as measured by hypocotyl and radicle length, was evaluated after one month, and the somatic embryos were transferred to fresh medium. After the second month of incubation, the conversion frequency of germinated embryos into the seedlings was assessed. In general, ETs of both of the tested spruce species cultured on a maturation medium amended with 5% PEG 4000 exhibited a tendency to produce a higher total number of embryos, as well as a higher number of cotyledonary embryos. The B line of P. abies produced a significantly greater number of cotyledonary embryos, relative to the control (no PEG). PEG only stimulated hypocotyl growth in embryos of both lines (A and B) of P. abies during the germination stage. Somatic embryos of Picea omorika were characterized by poor growth of both hypocotyls and radicles, irrespective of PEG treatment. The addition of PEG 4000 to the maturation medium did not improve the conversion frequency of germinated somatic embryos into somatic seedlings in either spruce species after a month of incubation on Margara medium. The effect of PEG 4000 on somatic embryogenesis efficiency was more evident in the ET of the two P. abies lines, relative to the P. omorika ET line, during both the maturation and the germination stage. Results indicated that the P. omorika ET line was almost completely insensitive to all of the PEG concentrations tested.
