Article Synopsis
- The study explores the effects of in vitro cultivation and cryopreservation on the bacterial diversity associated with two sweet cherry cultivars, 'Sunburst' and 'Mindaugė'.
- Different survival and regrowth rates were observed between the cultivars after cryopreservation, with metataxonomic analysis showing varying bacterial compositions before and after treatment.
- Inoculating the 'Mindaugė' shoot culture with specific bacteria was found to potentially enhance growth following cryopreservation by addressing growth suppression issues.
Antibiotics are used in plant in vitro tissue culture to eliminate microbial contamination or for selection in genetic transformation. Antibiotic timentin has a relatively low cytotoxic effect on plant tissue culture; however, it could induce an enduring growth-inhibiting effect in tobacco in vitro shoot culture that persists after tissue transfer to a medium without antibiotic. The effect is associated with an increase in oxidative stress injury in plant tissues.

- In vitro plant cultures from sterilized explants contain complex microbial communities, and while antibiotics are often used to decontaminate them, their effects on these communities and plant growth are not fully understood.
- A study on tobacco shoots found that adding the antibiotic timentin reduced biomass by 29% and increased oxidative stress, with only partial recovery in growth after removing the antibiotic.
- Microbiome analysis showed that antibiotic treatment significantly decreased microbial diversity, favoring a dominant bacterial family, suggesting that a diverse microbiome is important for successful in vitro propagation.
In vitro plant tissue cultures face various unfavorable conditions, such as mechanical damage, osmotic shock, and phytohormone imbalance, which can be detrimental to culture viability, growth efficiency, and genetic stability. Recent studies have revealed a presence of diverse endophytic bacteria, suggesting that engineering of the endophytic microbiome of in vitro plant tissues has the potential to improve their acclimatization and growth. Therefore, the aim of this study was to identify cultivated tobacco ( L.

Accordingly, plants have developed several adaptation mechanisms to deal with temperature stress. Chloroplasts are one of the organelles that are responsible for the sensing of the temperature signal and triggering a response.

One of the cellular responses of plants to cold stress is the accumulation of dehydrin proteins. We studied the expression of dehydrins in several Rosaceae species during low temperature treatment in vitro.
