“…Traditionally, tissue culture labs have sought to eliminate any signs of visible bacteria to improve micropropagation success (Thomas, 2010 ); however, some positive effects have been reported for endophytes in tissue‐culture plants (Murthy et al, 1999 ; Pohjanen et al, 2014 ; Quambusch et al, 2016 ; Kanani et al, 2020 ). For example, microbial symbionts play a role in plant responses to cold and freezing stresses (Acuña‐Rodríguez et al, 2020 ).…”

“…The types and quantity of endophytes vary throughout plant tissues, with roots in soil often being heavily colonized and young actively growing shoots possessing fewer endophytes (Wang et al, 2016 ; Gómez‐Lama Cabanás et al, 2021 ). In many cases, endophytes are believed to have positive effects on the plant, including assisting with nutrient acquisition, nitrogen fixation and phosphate solubilization, phytohormone and siderophore modulation and production, protection against abiotic stresses, and phytopathogen control (Dubois et al, 2004 ; Hardoim et al, 2008 , 2015 ; Reinhold‐Hurek and Hurek, 2011 ; Liaqat and Eltem, 2016 ; Rajamanickam et al, 2018 ; Proboningrum et al, 2019 ; Acuña‐Rodríguez et al, 2020 ; Kanani et al, 2020 ; Jiang et al, 2021 ). Some studies have shown that introducing endophytic bacteria is beneficial for both plant field performance and growth in in vitro culture systems (Murthy et al, 1999 ; Khan and Doty, 2009 ; Pohjanen et al, 2014 ; Quambusch et al, 2016 ; Patle et al, 2018 ), indicating a synergistic effect for these plant–endophyte interactions.…”

Minimizing the deleterious effects of endophytes in plant shoot tip cryopreservation

Plant cryopreservation technologies are used within gene banks for the long‐term preservation of vegetatively propagated collections. Surface‐sterilized plant tissues grown in the field, greenhouse/screenhouse, growth chamber, or in vitro are the source of shoot tips subjected to vitrification‐based cryopreservation methods. Here, we describe the methods used to minimize microbial contamination during the tissue culture initiation process. We also discuss the occurrence and possible elimination of endophytes after extended in vitro culture and during recovery after liquid nitrogen exposure. We describe two case studies in which bacterial endophytes were observed in Citrus gene bank accessions during recovery after cryopreservation. These were identified using the MinION Oxford Nanopore system and Kirby–Bauer disc diffusion assays to examine the bacterial responses to antibiotic exposure. The methods used in this case study could be applied to identify endophytes to better target antimicrobial treatments of plant tissue collections.

“…In this respect, the use of competent PGPMs in micropropagation under in vitro and ex vitro conditions was analyzed and called “biotization” ( Nowak, 1998 ). Microplant biotization is a biotechnological practice aimed at reducing chemical input in plant production ( Kanani et al, 2020 ). The biotization can be done at all stages of in vitro propagation.…”

Plant growth promoting microbes (PGPMs) play major roles in diverse ecosystems, including atmospheric nitrogen fixation, water uptake, solubilization, and transport of minerals from the soil to the plant. Different PGPMs are proposed as biofertilizers, biostimulants, and/or biocontrol agents to improve plant growth and productivity and thereby to contribute to agricultural sustainability and food security. However, little information exists regarding the use of PGPMs in micropropagation such as the in vitro plant tissue culture. This review presents an overview of the importance of PGPMs and their potential application in plant micropropagation. Our analysis, based on published articles, reveals that the process of in vitro classical tissue culture techniques, under strictly aseptic conditions, deserves to be reviewed to allow vitroplants to benefit from the positive effect of PGPMs. Furthermore, exploiting the potential benefits of PGPMs will lead to lessen the cost production of vitroplants during micropropagation process and will make the technique of plant tissue culture more efficient. The last part of the review will indicate where research is needed in the future.

“…This technology is designed to stimulate growth, development, reduce stress, and increase plant immunity in vitro by introducing bacteria and fungi into cultures [ 118 ]. New studies have revealed a positive effect of many microorganisms on the growth of the vegetative part of plants, seed maturation, resistance to pathogens, callus growth, and increased tolerance to low temperature [ 119 ].…”

The current investigation aimed to present an overview of the conservation of biological diversity of rare and endangered plant species. Methods of biodiversity conservation as well as several overview recommendations for the preservation of various rare species have been considered. An overview of the taxa included in the red book has been presented on the example of the Russian Federation. Global and local codes and classifiers of plant rarity were also presented. Future prospects for the conservation of biological diversity and the creation and development of bioresource collections have been considered.
