In the last decades, lighting installations in plant tissue culture have generally been renewed or designed based on LED technology. Thanks to this, many different light quality advances are available but, with their massive implementation, the same issue is occurring as in the 1960s with the appearance of the Grolux (Sylvania) fluorescent tubes: there is a lack of a methodological standardization of lighting. This review analyzes the main parameters and variables that must be taken into account in the design of LED-based systems, and how these need to be described and quantified in order to homogenize and standardize the experimental conditions to obtain reproducible and comparable results and conclusions. We have designed an experimental system in which the values of the physical environment and microenvironment conditions and the behavior of plant tissue cultures maintained in cabins illuminated with two lighting designs can be compared. Grolux tubes are compared with a combination of monochromatic LED lamps calibrated to provide a spectral emission, and light irradiance values similar to those generated by the previous discharge lamps, achieving in both cases wide uniformity of radiation conditions on the shelves of the culture cabins. This study can help to understand whether it is possible to use LEDs as one standard lighting source in plant tissue culture without affecting the development of the cultures maintained with the previously regulated protocols in the different laboratories. Finally, the results presented from this caparison indicate how temperature is one of the main factors that is affected by the chosen light source.

The endogenous bacterial contamination of plant tissue culture materials and their possible control was studied. Nine bacterial isolates were isolated from the contaminated tissue culture materials viz. potato and tea. On the basis of morphology and biochemical characters of nine isolates, seven were identified as Gram positive belonging to Bacillus alcalophilus, B. circulans, B. infantis, B. lentus, B. schlegelii, B. pumilus and B. subtilis. Remaining two were Gram negative and identified as Enterobacter cloacae sub. sp. dissolvens and Pantoea agglomerans. Molecular analysis was conducted on the basis of 16S rDNA sequence to confirm three isolates. Culture and sensitivity test was carried out to screen out the antibiotic sensitivity where streptomycin (S-10), polymyxin (PB-300) and gentamicin (CN-120) antibiotics were found to be effective against all bacterial isolates. The culture and sensitivity test reflected the feasibility to control or eliminate the contaminant bacteria during in vitro culture of plant which is very much required in the commercial tissue culture production.Plant Tissue Cult. & Biotech. 28(1): 99-108, 2018 (June)

Capsaicin, a secondary metabolite produced in capsicum, is in high demand in pharmaceutical industry because of its various medicinal properties. Currently, the supply of capsaicin depends upon its extraction from capsicum fruits. This limits the production of capsaicin as it depends upon agricultural produce. The current review has compiled information from various literature published on chemistry and importance of capsaicin along with its method of production. It also reviews the process of in vitro production of capsaicin through plant tissue culture, strategies of increasing capsaicin accumulation and its advantages over extraction from fruits and artificial synthesis.

Sodium Dichloroisocyanurate

Autoclaving nutrient media is still considered as the optimum mode of sterilisation in plant cell and tissue culture. During the process steam under high pressure is maintained at 120 degrees Celsius, 15 psi for 15-20 minutes in a chamber, optimised to kill all possible microbial life forms. But the disadvantages related to the process of autoclaving are plentiful. They are, decrease in the media pH, salt precipitation, agar depolymerisation, carbohydrate hydrolysis, volatile obliteration and necessity of the infrastructure investment. Requirements of additional resources (time, human resources, electrical energy) have forced the lookout for a more viable alternative, that is, chemical sterilisation. The use of Sodium dichloroisocyanurate (NaDCC) is a useful alternative for media and explant sterilisation. NaDCC is stable, water-soluble, non-toxic and easy to use at room temperature, does not have any environmental hazards and is not phytotoxic. The use of NaDCC as a disinfectant has been documented well concerning water sterilisation, surface sterilisation and also as a broad spectrum disinfecting agent. Disinfecting property of NaDCC is due to the hydrolytic release of chlorine, and this can be utilised for sterilisation of media and explants in plant tissue culture. NaDCC is a useful alternative for autoclaving at a concentration range of 0.05 to 1.0 g/l. However, only a few reports are available for its use as a sterilising agent for media and explants for in vitro cultures of plants. This paper discusses and reviews the possibility of establishing NaDCC as an active agent for explant sterilisation and as a viable alternative to medium sterilisation through autoclaving.

In vitro culture of plant cells/tissues is now routine using a range of explant types from many of the important vegetable and fruit crops. Successful technologies include isolation, culture of tissues, cells, protoplasts, organs, embryos, ovules, anthers and microspores and regeneration from them of complete plantlets. The development of plant tissue culture technology represents one of the most exciting advances in plant sciences. For example, the prospect of being able to introduce, develop, produce, transfer and conserve the existing gene pool of plant sciences by using tissue culture methods opens up new opportunities for researches and entrepreneurs. The term plant tissue culture should denote in vitro cultivation of plant cells or tissues in an unorganized mass, i.e., callus culture. Plant tissue culture techniques, in combination with recombinant DNA technology, are the essential requirements for the development of transgenic plants. However, culture techniques like anther/pollen/ovule culture, meristem culture can themselves be utilized for crop improvement or may serve as an aid to conventional breeding. In recent, isolated microspore culture has developed as a breeding tool and an experimental system for various genetic manipulations. The inherent potentiality of a plant cell to give rise to a whole plant, a capacity which is often retained even after a cell has undergone final differentiation in the plant body, is described as ‘cellular totipotency’. On the other hand, production of virus-free plants via meristem culture can reduce losses caused by phyto-pathogens. Embryo culture has many potential uses ranging from overcoming seed dormancy to facilitation of inter-specific hybridization. Protoplast fusion technique can be used for the transfer of cytoplasmic male sterility from one species to another in a short period of time. In cabbage, male sterile cybrids are being utilized by seed companies to produce hybrid seeds on commercial scale and at competitive rates. Plant tissue culture and cell culture are providing useful methods for germplasm storage either by low temperature storage of organized tissue, or cryopreservation of cell or embryo culture.

Micro Propagation

The multiplication efficacy by bulb is low and the plantlets are more susceptible to disease, therefore, there is a need to develop a protocol for its propagation. Lilium candidum is listed in the saitma prefecture Red Data Book as a critically endangered plant and rescuing information regarding its micro-propagation is rather limited. On this regard, the application of in vitro micropropagtion procedure might help to obtain large numbers of uniform plants of endangered species of Lilium. Dried lilies are a rich source of fiber and also rich in sodium and carbs. Lily bulbs have proteins and starch and also small quantities of iron, calcium, phosphorous, and vitamin B1, B2, C. The health benefits of the lily for the heart are well known on account of the active cardiac glycosides as well as the flavonoids which tend to stimulate the arteries and can cause them to dilute. Another one of the therapeutic uses of the lily flower is in the case of treating burns and preventing the formation of scar tissue. One of the main health benefits of the lily flower is that it helps regulating the heart rate there by allowing the heart to function more efficiently and regular. Having multiple medicinal properties we decided to cultivate Lilium candidum using plant tissue culture so farming can be increased using this cost efficient techniques. In this research, we have studied various Effect of different concentration of BAP and NAA on the initiation of Lilium candidum from bulb and IBA, IAA and NAA on the rooting of shoots of Lilium Candidum.

Objective: The purpose of the present study was to isolate and characterize bacterial contamination from in vitro culture of Bacopa monniera callus culture.Methods: The two selected isolates (1 and 2) were identified by morphological, biochemical and molecular (16S rRNA gene sequencing) methods. Beside this antibiotic resistance was also determined.Results: The isolates were identified as closely related to Enterobacter cloacae (KU350623) (Isolate 1) and Myroides odoratimimus (KU382740) (Isolate 2). The isolate 1 and 2 were found to be resistant to streptomycin (25 mcg), dapsone (10 mcg), erythromycin (15 mcg), chloroamphenicol (25 mcg) and ampicillin (10 mcg). Supplementation of the natural extract was tested to control the contamination due to these multi drug resistant bacteria. Aqueous and alcoholic leaf extracts of Azadirachta indica was added to plant tissue culture media i.e. MS media in order to control contamination.Conclusion: The present studies suggest using natural extracts supplementation as a promising strategy to control the in vitro bacterial contamination in plant tissue culture.

An experiment was carried out in Plant Tissue Culture Laboratory, Department of Crop Botany, Bangladesh Agricultural University, Mymensingh to investigate the effect of banana extract on micropropagation of  <i>Dendrobium</i> sp. var. Sonia orchid through PLBs. The experiment was conducted during July 2012 to October 2013. Half-Murashige and Skoog (1/2MS) medium were used as basal medium and the medium was supplemented with banana extract at 12.5, 25, 50, 100, and 200 ml L-1 with a control, where no banana extract was supplemented. The cultures were done in 100 ml conical flasks and maintain at 25°C with 30µ mol m-2 S-1 lighting provided by florescent tubes for 16 hours per day. Banana extract showed significant effect on growth and development of PLBs. Among the treatments, 100 ml L-1 banana extract enhanced new PLBs regeneration from explanted PLBs and growth and development of PLBs. Present research indicated that nutrient requirement for PLBs multiplication and plantlets growth of  Dendrobium orchid is quantitatively different in vitro. Finally, 100 ml L-1 and 25 ml L-1 of banana extract may be recommended as supplement into 1/2MS medium for PLBs multiplication and plantlet regeneration, respectively in vitro.The Agriculturists 2015; 13(1) 101-108
