Plant cells and tissues

Because of cell speciaHzation, some produces are produced in cultures of those cellular types. Three main classifications of the types of plant cell and tissue cultures are ... 

The production of secondaiy metabohtes has often been characterized using the classical equations of Leudeldng and Piret. However, the complexities of plant cell and tissue cultures have led to revisions to this equation to include fresh cell weight and viability, cell expansion, and culture death phase. Therefore, the production model is written as the following ...

In this review, we focus on the use of plant tissue culture to produce foreign proteins that have direct commercial or medical applications. The development of large-scale plant tissue culture systems for the production of biopharmaceutical proteins requires efficient, high-level expression of stable, biologically active products. To minimize the cost of protein recovery and purification, it is preferable that the expression system releases the product in a form that can be harvested from the culture medium. In addition, the relevant bioprocessing issues associated with bioreactor culture of plant cells and tissues must be addressed.

Plant cytochemistry/histochemistry continues to evolve as fluorescence microscopy (16-19), confocal fluorescence microscopy (20,21), and microspectrophotometry (22) expand our quantitative knowledge of the distributions of chemical constituents in plant cells and tissues. With regard to microspectrophotometry, this is possible for single cells, as the Arcturus Corporation (Mountain View, C A) has developed an instrument capable of isolating single cells.

As mentioned, chemical fixation of plant cells has been reviewed many times (15-20) and the reader is referred to these citations for a variety of fixation procedures for preserving plant cells and tissues. One of the most recent references regarding the topic is that of Hopwood and Milne (21). Table 1 presents their recommendations regarding fixation of plant cells and tissues for electron microscopy.

The purpose of this chapter is to review the state of knowledge about the endophytic fungal species that inhabit the spaces within and between plant cells and tissues and to examine the array of secondary products produced by these fungal inhabitants. In the few cases in which enough is known, the details of the biosynthesis of these compounds, the medicinal uses to which these compounds have, and the potential for culture of the fungi as industrial producers of the metabolites will be discussed. 

Production of anthocyanins in plant cell and tissue cultures has been reported for more than 30 species including Daucus carota, Fragaria x ananassa, Vaccinium spp., Vitis hybrida, Solanum tuberosum, Malus sylvestris, Aralia cordata, Perilla frutescens, Ipomoea batatas. Euphorbia millii, Strobilanthes dyeriana. Hibiscus sabariffa, Dioscorea cirrhosa, etc. ...

The damage to animal or plant cells and tissues caused by ROS is called oxidative stress, which is caused by an imbalance between the production of reactive oxygen and a biological system s ability to detoxify the reactive intermediates or repair the resulting damage. A particularly negative side of oxidative stress is the production of ROS, which includes free radicals.
