1 results about "Protoplasm" patented technology

Protoplasm is the living content of a cell that is surrounded by a plasma membrane. In some definitions, it is a general term for the cytoplasm (e.g., Mohl, 1846), but for others, it also includes the nucleoplasm (e.g., Strasburger, 1882). For Sharp (1921), "According to the older usage the extra-nuclear portion of the protoplast [the entire cell, excluding the cell wall] was called "protoplasm," but the nucleus also is composed of protoplasm, or living substance in its broader sense. The current consensus is to avoid this ambiguity by employing Strasburger's [(1882)] terms cytoplasm [coined by Kölliker (1863), originally as synonym for protoplasm] and nucleoplasm ([term coined by van Beneden (1875), or] karyoplasm, [used by] Flemming [(1878)])". The cytoplasm definition of Strasburger excluded the plastids (Chromatoplasm).

Chilli cytoplasm male sterile line protoplast separation purification and callus forming method

The invention provides a chilli cytoplasm male sterile line protoplast separation purification and callus forming method, which relates to the protoplast source, separation, purification and protoplast culture and callus forming and belongs to the field of biotechnology science. The method comprises the following steps that: 1, chilli cytoplasm male sterile line aseptic seedling main leaves are used as materials for separating the protoplast; 2, young tender blades are cut and are placed into a CPW9 enzymolysis solution containing cellulase, pectinase and macerozyme, and the solution is placed onto a 27 DEG C shaking bed for dark treatment; 3, the enzymolysis liquid is filtered by a 300-mesh nylon sieve, and the protoplast is collected after centrifugation washing; and 4, the obtained protoplast is cultured into a liquid culture medium containing hormone in different concentrations, and fresh culture media are regularly added in the period until the callus is formed. In the method, the chilli male sterile materials are used for carrying out protoplast separation and culture, and important significance is realized on further studying the protoplast fusion and using the fusion technology for realizing the development of the novel chilli cytoplasm male sterile line materials.
