[PMID: 38610046 PMCID: PMC11010404 DOI: 10.1186/s13007-024-01161-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 02/19/2024] [Indexed: 04/14/2024]
Abstract
BACKGROUND QUERCUS: seeds that are recalcitrant to desiccation and freezing temperatures cannot be stored in gene banks under conventional conditions. However, the germplasm of some recalcitrant seeded species can be stored in liquid nitrogen (-196 °C). Unfortunately, for many species, among them for almost the whole genus Quercus, an effective cryostorage method is still unknown. In this study, we propose a successful cryostorage protocol for Quercus petraea (Matt.) Liebl. germplasm using plumules (a shoot apical meristem of an embryo) frozen on aluminium cryo-plates. RESULTS: The plumules isolated from the acorns of ten provenances were prestored in 0.5 M sucrose solution (for 18 h). To form alginate beads (one plumule per bead), the plumules were placed in the wells of a cryo-plate and embedded in calcium alginate gel. For cryoprotection, the encapsulated plumules were immersed in cryoprotectant solution containing 2.0 M glycerol and different concentrations of sucrose (0.8-1.2 M) for 40 min at 25 °C and desiccated under a laminar flow cabinet for 1.0-4.0 h. Cryo-plates with plumules were directly immersed in liquid nitrogen and then cryostored for 30 min. For rewarming, cryo-plates with plumules were immersed in 1.0 M sucrose solution and rehydrated for 15 min at 25 °C. Survival rates varied from 25.8 to 83.4 were achieved after cryoprotection in 1.0 M sucrose solution and the drying of plumules for 2 h. The in vitro regrowth rate of cryopreserved plumules varied among provenances and was 26-77%. CONCLUSIONS: This study presents, for the first time, a successful, simple and effective protocol for the cryopreservation of Q. petraea germplasm that could be used in gene banks. The experiment was successfully repeated on seeds from various provenances, each yielding similar, good results. However, seed quality and storage time after harvesting are important factors in plumule regrowth after cryopreservation.

Jenderek MM, Yeater KM, Thomas AL. Germplasm of Ozark chinquapin (Castanea ozarkensis Ashe) can be cryopreserved by dormant winter buds. Cryobiology 2024; 114:104833. [PMID: 38072181 DOI: 10.1016/j.cryobiol.2023.104833] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 11/28/2023] [Accepted: 11/29/2023] [Indexed: 12/21/2023]
Abstract
Ozark chinquapin (Castanea ozarkensis Ashe) is a forest tree, endemic to the Ozark Mountain region in Eastern United States. Its nutritious nuts were consumed by Native Americans, European settlers, livestock, and wild animals and its wood was an important rot-resistant construction material. Once a significant tree in regional forest communities, the species was nearly eradicated by a chestnut blight caused by Cryphonectria parasitca (Murill) Barr fungus. Some individuals have survived as sprouts from adventitious root buds, but they rarely reach reproductive maturity. While some in situ restoration efforts are underway, the development of a viable ex situ germplasm preservation method is critical to the conservation of this important food-bearing species. Our experiment aimed to develop a cryopreservation method for C. ozarkensis dormant winter buds subjected to eight experimental treatments before desiccation, slow cooling, and storage in liquid nitrogen vapor. The highest post cryogenic viability was 91.2 % for dormant buds pretreated with 0.3 M sucrose for 16 h followed by 0.75 M sucrose for 3 h; this treatment is suggested for cryopreservation of dormant winter buds of Ozark chinquapin germplasm.

Abstract
Several plant secondary metabolites are used in the production of different pharmaceuticals based on their biological activities. The conservation and sustainable use of medicinal plants is important for the industrial production of plant-based medicines. Different cryopreservation methods are used for long-term culture preservation, which allows fast regeneration of the preserved plant material with the maintenance of its primary original traits. These methods could ensure the sustainable indefinite supply of plant tissues for theoretically unlimited periods of time, and have gained considerable attention in recent years. It is important to assess the recovery rate and the genetic stability of the recovered plant tissues after cryopreservation because cryopreservation efficiency differs among plant tissues and species. This review lays particular emphasis on the pharmaceutical applications of plant secondary metabolites that are produced through tissue culture approaches, highlighting the methods used for their cryopreservation, as well as their recovery and genetic stability.

Abstract
Seeds are the most commonly used source of storage material to preserve the genetic diversity of plants. However, prior to the deposition of seeds in gene banks, several questions need to be addressed. Here, we illustrate the scheme that can be used to ensure that the most optimal conditions are identified to enable the long-term storage of seeds. The main questions that need to be answered pertain to the production of viable seeds by plants, the availability of proper protocols for dormancy alleviation and germination, seed tolerance to desiccation and cold storage at -20 °C. Finally, it is very important to fully understand the capability or lack thereof for seeds or their explants to tolerate cryogenic conditions. The proper storage regimes for orthodox, intermediate and recalcitrant seeds are discussed.

PLANTS (BASEL, SWITZERLAND) 2022; 11:3308. [PMID: 36501347 PMCID: PMC9738486 DOI: 10.3390/plants11233308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 11/16/2022] [Accepted: 11/27/2022] [Indexed: 06/17/2023]
Abstract
Castanea sativa cv. 'Garrone Rosso' and 'Marrone di Castel del Rio' are two of the most prized varieties in Italy due to their valuable and healthy nuts used for fresh consumption and in the confectionery industry. Despite the growing demand for chestnuts, there are constraints regarding plant propagation that hamper the renewal and new planting of orchards in different areas. Castanea sativa is susceptible to diseases that have caused a reduction in its area of production. For this reason, in vitro culture represents a valuable technique for germplasm preservation and plant multiplication enabling production of a high number of plants for use in breeding programs. Here we present an in vitro micropropagation protocol for Italian Castanea sativa cv. 'Marrone di Castel del Rio' and cv. 'Garrone Rosso' to contribute to the preservation and enhancement of the Italian germplasm. Nodal explants were used as the starting material for in vitro establishment. The cv. 'Marrone di Castel del Rio' showed a high percentage of survival explants (92%) when subjected to long bleach exposure (25 min), in contrast to what was observed for the 'Garrone Rosso' cultivar. Ascorbic acid was found to be the best compound to counteract phenol exudation. The MS3B and DKW media supplied with 0.5 mg/L BAP were effective for in vitro establishment, while the DKW medium (0.1 mg/L BAP and 0.05 mg/L IBA) was preferable for the proliferation phase. A double-layer rooting methodology was used and 35% rooting was observed with 25 mg/L IBA rooting treatment.
