Protoplast culture and regeneration status of
O ms, 500 ~ -0750 volt electric pulse treatment of protoplasts formed by roots of plants has also been stimulated. Regeneration time is 84 days from the Need to O5 samples treated to 119 days. Compared with the Colt cherry, observed morphological variation in regenerated plants more ', such as high voltage (1250 V,[link widoczny dla zalogowanych], 1O to 30 microseconds) protoplast electroporation under the formation of seedlings are short, in these dwarf seedlings, root development has been inhibited. However, they are transferred to hormone-free medium, these plants were seedlings grow into plants with normal phenotype. In future studies, to determine electroporation on protoplast-derived callus occurred within the hormone balance is similar to its role in the power of tobacco callus treatment proposed, it will be very interesting. Electroporation on the growth of native stimulus effects of the flag body does not mean that the technology can never be used to induce the cell protoplast. Indeed,[link widoczny dla zalogowanych], the general applicability of the technology needed to fully evaluate. Overall, these results show the separation of the electroporation of protoplasts and stability not only in the transition into the study but also in promoting cell growth and regeneration fighting has practical value. l! determine cell life span is thousand Why? Tian Zhong Chang as a married organisms can be (Protoctista) cells of a slime mold, especially in Dictyostelium discoideum (Dictyoste-Humd ~ scoideum) is a research determine cell life What is it? \Qi was originally generated an interest (1935). The cellular slime mold has many features, can be summed up when a single cell is a multi-celled organisms and the biological properties of both sides that is, to the bait during the period, with the second into the breeding behavior of single-cell organisms. However, if the wine to the bait that will stop breeding, and formed into the shape of, and thus form a multi cell body, showing the behavior of multi-cellular organisms. However, even in the form of post-formation, will also diversify its more mechanical cell body, and access to the nature of the original single cell organisms. In other words, cell shape formation and development of slime mold differentiation is reversible. spider cell of the slime mold life cycle,[link widoczny dla zalogowanych], and relies on sign to stop the propagation of the cell after the slime mold (In general, six are small version of frog slime mold Dictyostelium discoideum as when the life cycle of the said j ah please refer to the Circuit 1.. The first is In the known 6 VIII. Conclusion 8 hours in the middle of a period of time, for the formation of multicellular preparations. Later, as the seedlings off in a slime mold chemotaxis deformed starting material intermittently cAMP ground (interval 5-1O minutes) begins to secrete. Thus, in its echoes around the slime mold plasmodium Jibei cited nearly at the same time, cited deformed near the slime mold itself to the secretion of intermittent cyclic adenosine acid stimulation is intermittently carried out. cAMP reason for taking into account the intermittent secretion of Mother biological significance, is to rely on the surrounding state of cAMP concentrations close to zero,[link widoczny dla zalogowanych], so that it can return to the same mechanism may re-action. In these circumstances, the general viscosity of about 1O million seedlings deformed gathering, they gathered to form a cell group, we began to form a cell block, 'at this time on its surface is curved substance secreted from the cell coverage, which assembled into multicellular. accumulation of each cell can not directly finance units, then the group should take a unified organization for action. phototaxis is known as a mobile system in the medium body and from the action. In a moving body, its points before they are 1 / 3 of stem cells cells, and subsequently part of the 2 / 3 spore. At this point, that is completely ended the life of cells. They were porridge that was scheduled to stalk cells (prestalkcel1) and pre-spore cells (presporecel1) . If the body off the offensive action, the various fragments of tissue can be re-compiled, re-formed with in this very short on protoplast isolation, culture and regeneration of the comments, it is clear some people to hide the birth of technological progress has recently been r , which for the somatic cell hybridization, somatic hybridization and transformation of gametes has requested the meaning of Chu. the cultivation of plants in several difficult applications have now become the hit of the things Pat has, thus making them more crop species on the basis of genetic manipulation Yun can actually put them into the field Zhi preface to improve. * Shao Hongbo early career translated cPlan'tCell, Tis' - sueandOrganCul} ure, 1988 care, 1,1.5, a 125. * 33,
