Synopsis
Isolated plant protoplasts are 'naked' cells that have had their cell wall removed either by mechanical action or by enzymic digestion. As a result of wall removal the only barrier that exists between the cell protoplasm and the external environment is the plasma membrane. The removal of the cell wall has drastic osmotic consequences for the isolated cell. Rather like animal cells, the isolated protoplasts must be maintained in an osmotically balanced (isotonic) nutrient medium or they will burst. As will be seen later, the isolation of plant protoplasts is not a particularly new event; as early as the 1890s scientists were isolating protoplasts mechanically and studying effects such as protoplast streaming. What has brought protoplast technology to the forefront of plant biology is the potential application of these structures in non-traditional plant improvement methods. Extreme care must be exercised by the reader, however, in be- lieving some of the claims that have been put forward for the use of protoplasts in improvement programmes. In the 20 years since the first experiments in routine enzyme isolation of large numbers of protoplasts no real improvement has been obtained in a commercial crop plant. This does not mean that improvement is impossible; it simply indicates that it may be a longer term objective than some people would like to admit., Isolated plant protoplasts are 'naked' cells that have had their cell wall removed either by mechanical action or by enzymic digestion.

- l***c (227)- Feedback lasciato dall'acquirente.Mese scorsoAcquisto verificatoBook came packaged well to avoid damage, in great condition. Not sure if the seller delayed shipping or if usps didn’t update the shipping, which is highly likely. Still received and we are happy with our purchase. I had trouble looking up tracking due to the company they used but seller found usps tracking and sent that over quickly. Sellers communication was excellent. Would buy from again. Item as described.
- t***n (2908)- Feedback lasciato dall'acquirente.Mese scorsoAcquisto verificatoI don't give negatives; However, description was not correct; No price guide was included in this book.As you will see in book pic shown; title states price guide included, no price guide inside. Communication poor, description, no communication price guide missing from this book. Shipping time was weeks before it was even shipped. Blamed the shipping on warehouse. You own & operate a business; your warehouse is not up to standards you change who you do business with. It's your responsibility.
- -***6 (133)- Feedback lasciato dall'acquirente.Ultimi 6 mesiAcquisto verificatoItem arrived as described and adequately packaged. Ridiculously long shipping time. Seller posts incorrect tracking number and lists the item as shipped. Contacted seller for correct tracking, received a new tracking number with the warning that the number won’t be “live” until the item is shipped. Will you get your item? Yeah, probably. Count on it being delivered 2-3 weeks longer than expected.
