Beyond its use for large-scale micropropagation and other potent biotechnological techniques, plant tissue culture is an important tool for studying the biology, biochemistry, molecular biology, and communication of plants under controlled environments and on artificial, well-defined media.
Plants are constantly exposed to the influence of their environment. Being sessile organisms, plants are not able to escape from their changing surroundings. Climate change and environmental stability are critical, largely because plant growth, development, and reproduction are regulated by seasonal cues. Therefore, their ability to sense and respond to different environmental stimuli—either chemical or physical—are of adaptive and even evolutionary importance. Recent findings support the importance of physical signals like visible light, UV light, temperature, acoustic waves etc. in the adaptation of plants to environments with mostly suboptimal conditions by changing their growth and development. Regarding the developmental aspect, some studies have suggested that ROS signaling as messengers or transmitters of environmental cues are involved in regulating seed germination.
The benefit of perceiving and responding to physical signals includes that they are able to spread more rapidly and with less energy costs than chemical triggers, allowing plants to alter their growth and development accordingly. The effects of environmental physical factors and signals can be well studied using plant tissue cultured cells, tissues, explants, organs, or plantlets. In plant tissue culture, the organ development and morphogenesis can be regulated and modified by changing the in vitro physical conditions, like light, temperature, sound or ultrasound waves, etc. Environmental cues and signals (physical or chemical) are also of importance in tissue-culture-related methods. As an example, cryopreservation involves the exposure of in vitro cells or tissues to physical, chemical, and physiological stresses causing cryoinjury, and a perspective of cryobionomics is that molecular changes may be indicative of a positive adaptive response to the stresses incurred which may be advantageous to post-storage survival.
This Special Issue aims to cover various aspects of plant tissue culture as a tool, where the plant plasticity to different environmental cues and signals—primarily but not exclusively physical ones—are studied, including molecular, biochemical, biophysical, morpho-physiological, growth, and developmental aspects of plant response. Studies on the effects of physical cues and signals modifying the plant physiology, development, and growth in various tissue culture and related methods will also be presented. Studies focusing on epigenetic and transcriptomic reprogramming are welcome.

Abstract: All organisms on Earth are affected by its environment. Cues and signals of the environment in nature can be either beneficial and supportive or detrimental from the growth and developmental perspective. Plants, despite their immobility, have developed advanced strategies to overcome the various and changing environmental impacts, and stresses. In vitro plantlets, tissues and cells are constantly exposed to the influence of their environment as in nature. Under in vitro conditions the environmental factors are well-controlled therefore their effects can be well studied. Light has a widely known morphogenetic effect on plants, however, other physical cues are at least so important but often neglected. We summarize in this review our knowledge about the role of the main physical environmental factors beyond electromagnetic waves in in vitro culture of plants. We focus on the role of mechanical stimuli, like sound, ultrasound, touch, wounding etc., and temperature. We summarize the molecular, biochemical, physiological, growth and developmental changes they cause and we present how these processes are controlled in the plants. Moreover, we present how their regulating or stimulating roles are applied in plant biotechnological applications, like in Agrobacterium-mediated transformation or cryopreservation.

Abstract: Production of healthy planting material is based on the micropropagation of virus- and pathogen-free in vitro shoot cultures of vegetatively propagated species. Beside culture of isolated meristem the thermotherapy, chemotherapy, electrotherapy and cryotherapy are applied for virus elimination. Thermo- and chemotherapy are most frequently used, however, combined treatments are also very common (e. g. meristem isolation with chemotherapy, chemotherapy with thermotherapy and so on). During these processes plantlets are suffered by several stress, which can result in low rate of survival, or inhibited growth, incomplete development, abnormal morphology. Even though the in vitro shoot cultures survive the treatment, further development can be inhibited thus regeneration capacity of treated in vitro shoots play also important role in successful virus elimination. Sensitivity of genotypes to treatments is very different and the rate of phytotoxicity depends on the applied in vitro environmental condition, as well. When applying thermotherapy, the phytotoxicity or plant survival depends on the temperature, illumination, duration of thermotherapy. In the case of chemotherapy, the type and concentration of antiviral agent, duration and repetition of treatment are the main factors of phytotoxicity. This review summarize the phytotoxic effect of virus-elimination treatments applied on tissue cultures reported in the literature.
