Comparison of the Polypeptide Complement of Different Plastid Types and Mitochondria of Narcissus pseudonarcissus
نویسندگان
چکیده
The protein complement of chloroplasts, prochromoplasts, chromoplasts, and mitochondria of the daffodil (Narcissus pseudonarcissus) has been investigated comparatively by gel electro phoresis. Mitochondria do not share common proteins with plastids. On the other hand, there is a broad overlap of the protein complement of the three plastid types investigated, in spite of their different fine structures. There are, however, remarkable differences regarding the relative amounts of many protein species, and certain plastid proteins are entirely absent either from the chloroplasts (e.g., 2 chromoplast proteins in the 60 kDa range) or the chromoplasts (e.g., LHCP). The protein complement of prochromoplasts, which contain chlorophylls and the LHCP, is nevertheless quite more similar to the protein pattern of the chromoplasts than to the one of the chloroplasts.

Apparent Identity of Chromoplast and Chloroplast DNA in the Daffodil, Narcissus pseudonarcissus
Although chromoplasts and chloroplasts are mor phologically and functionally very different, it has been shown in certain plants and under certain con ditions, that they are interconvertible [see 1 5]. One could then expect such plastids to contain, at least qualitatively, the same plastome. It appears questionable, however, whether this applies to all plastid types. For example, FreyWyssling...
متن کاملNew Gold in Them Thar Hills: Testing a Novel Supply Route for Plant-Derived Galanthamine
Many secondary plant compounds are synthesized in response to stressed growing conditions. We tested the feasibility of exploiting this feature in a novel strategy for the commercial production of the plant alkaloid galanthamine. Experimental lines of Narcissus pseudonarcissus were established under marginal upland permanent pasture at four different sites. Over 80% of bulbs successfully establ...
متن کاملSeed development and maturation in early spring-flowering Galanthus nivalis and Narcissus pseudonarcissus continues post-shedding with little evidence of maturation in planta
BACKGROUND AND AIMS Seeds of the moist temperate woodland species Galanthus nivalis and Narcissus pseudonarcissus, dispersed during spring or early summer, germinated poorly in laboratory tests. Seed development and maturation were studied to better understand the progression from developmental to germinable mode in order to improve seed collection and germination practices in these and similar...
متن کاملA Simple and Rapid Method for Isolating High Quality Rna from Flower Petals
A simple RNA isolation method based on hot borate and proteinase K was used to extract high-quality RNA from petals of daffodils (Narcissus pseudonarcissus L. 'Dutch Master'). The method was adapted from the isolation technique described by Wan and Wilkins (1994). A single isopropanol precipitation and ethanol wash replaced all the second day steps of the Wan and Wilkins procedure. The RNA isol...
متن کاملIdentification of genes associated with perianth senescence in Daffodil (Narcissus pseudonarcissus
We used a PCR-based subtractive procedure to isolate genes that increased in abundance in the perianth of incipiently senescent daffodil (Narcissus pseudonarcissus L. ‘Dutch Master’) flowers. Using RNA gel blot analysis we confirmed that 18 of the transcripts were senescence-associated. A number of these have homologs in previously-studied senescing floral and leaf tissue systems (cysteine prot...
