Presently, the ultrastructure of the cytoplasm of the egg cell and pollen tube—immediately before fertilization and during cytoplasmic transmission of male gametophyte—has been described for the same species. The fate of parental plastids and mitochondria in the proembryo has also been followed. The mature egg cell contains a large amount of mitochondria, but seems to lack normal plastids. Most plastids have transformed into large inclusions. Apart from the large inclusions, there are abundant small inclusions and other organelles in the egg cell. During fertilization, pollen tube penetrates into the egg cell at the micropylar end and thereafter the contents are released. Plastid and mitochondrion of male origin are lacking near the fusing sperm_egg nuclei. The second sperm nucleus—not involved in karyogamy—remains at a site near the receptive vacuole. This nucleus is surrounded by large amount of male cytoplasm containing mixed organelles from the sperm cell, tube cell, and egg cell. At the free nuclear proembryo stage, organelles of male and female origin are visible in the perinucleus_cytoplasmic zone. Most of the mitochondria have the same morphological features as those in the egg cell. Some of the mitochondria appear to have originated from the sperm and tube cells. Plastids are most likely of male gametophyte origin because they have similar appearance as those of the sperm and tube cell. Large inclusions in the egg cell become vacuole_like. Paternal plastids have been incorporated into the neocytoplasm of the proembryo. In the cellular proembryo, maternal mitochondria are more abundant. Plastids resembling those of the sperm and tube cell are still present. These cytological results clearly show that in P. tabulaeformis, plastids are inherited paternally and mitochondria bipaternally. The cytological mechanism of plastid and mitochondrion inheritance in gymnosperm is discussed.展开更多

The results indicate that the sperms of Pinus tabulaeformis Carr. contain abundant plastids, mitochondria and organelle DNA. These data provide reliable cytological evidence of paternal plastid and mitochondrion inheritance in Pinus . The results are in line with the confirmed general rule of paternal plastid inheritance in Pinaceae. But whether mitochondria in sperm cells can be transmitted into the embryos is an issue needs further developmental studies. Another important finding is that contrary to earlier classification of the male gamete of Pinaceae into the male nuclei type, the results reveal that male gametes in Pinus tabulaeformis are actually cells. However, the sperm cells are only surrounded by plasma membranes without cell walls. The larger leading sperm cell in a pollen tube section is long in shape, with a large amount of cytoplasm; while the second sperm cell is smaller, round in shape and contains less cytoplasm. Whether this feature of the male gamete type could be considered as a representative characteristic of the family is discussed and further conclusions await more experimental evidences from studies on plants from different species.展开更多

Hook. and Cryptomeria fortunei Hooibrenk. The chloroplast trnL trnF region and one intra genic segment of the mitochondrial gene, Cox Ⅲ, were amplified from those of the parents and hybrids by PCR using gene specific primers. Cp and mtDNA polymorphisms of the amplified regions were detected between the parents after restriction digestions. Restriction fragment length polymorphism (RFLP) analysis revealed that all the F 1 individuals possessed Cox Ⅲ restriction fragment patterns (characteristic of the paternal parent Cryptomeria fortunei ) and the trnL trnF region (identical to the maternal parent Cunninghamia lanceolata ) showing that a different mode of inheritance for organelle DNA has occurred in the hybrids. Furthermore, the maternal inheritance of chloroplast DNA is reported here for the first time in coniferophyta.展开更多

The cpDNA fingerprints of hybrids from reciprocal crosses between Xushu18 and AB78-1 were found to be identical to those of their female parents, which reveals that cpDNA of sweet potato is maternally inherited in this intervarietal crossing. This maternal cpDNA transmission pattern does not accord with the putative one based on former cytological studies. The plastid inheritance in Convolvulaceae has been briefly reviewed in this study, and the utility of DNA restriction fingerprinting analysis in the study of plastid inheritance is also discussed.展开更多

The results showed that cry1A had been transmitted to progeny of transgenic maize as a single gene. Contents of cry1A insecticidal protein were significantly different among transgenic maize lines and various tissues of the same transgenic lines. High expression of cry1A protein occurred in green tissues, such as leaf and husk leaf, and low expression occurred in pith, tassel, ear pith, pollen and silk. The results also showed that the contents of cry1A insecticidal protein in leaves of transgenic maize increased with the advance of development and there was no significant difference in cry1A expression level among various generations of transgenic maize.展开更多

This maternal cpDNA transmission pattern does not accord with the putative one based on former cytological studies. The plastid inheritance in Convolvulaceae has been briefly reviewed in this study, and the utility of DNA restriction fingerprinting analysis in the study of plastid inheritance is also discussed.
文摘The inheritance of plastid DNA in Pharbitis was studied by the method of restriction fragment length polymorphisms (RFLP).Experimental results showed that plastid DNA from Pharbitis was paternally inherited in reciprocal crosses,P. nil ×P. limbata and P. limbata×P. nil hybrids.But,in the cross of P. limbata×P. nil,the possibility of biparental inheritance of plastid DNA could not be roled out in our preliminary experiment.Thus Pharbitis became the third genus among angiosperms characterized with male plastid transmission.The mechanisms of paternal plastids DNA inheritance in Pharbitis is unclear.The authors proposed that dilution,exclusion and/or degeneration of maternal plastid,including their DNA,after fertilization should be considered.
文摘We investigated the inheritance and expression of cry1A gene in transgenic maize ( Zea mays L.) by Southern blotting analysis and enzyme_linked immunosorbent assays (ELISA). The results showed that cry1A had been transmitted to progeny of transgenic maize as a single gene. Contents of cry1A insecticidal protein were significantly different among transgenic maize lines and various tissues of the same transgenic lines. High expression of cry1A protein occurred in green tissues, such as leaf and husk leaf, and low expression occurred in pith, tassel, ear pith, pollen and silk. The results also showed that the contents of cry1A insecticidal protein in leaves of transgenic maize increased with the advance of development and there was no significant difference in cry1A expression level among various generations of transgenic maize.

文摘Cultural characteristics of the traditional architectural environment and places of traditional cultural activities in Hanjiaxiang Village,an immigrant village of the Ming Dynasty located in the present Yuangong Township,Chenggu County of Shaanxi Province,were studied to analyze influence of geographical environment,history and culture,and social environment on the village cultures.Specifically,cultural characteristics of traditional architectural environment in this village were elaborated from spatial layout,architectural structure,architectural style and village landscapes.In terms of places for traditional cultural activities,layouts and cultural characteristics of places for the clan's sacrifice and community's fire,traditional sacrifice activities,and local opera performances were introduced.On this basis,cultural inheritance means for the protective renovation and construction of overall village spaces,village buildings,village landscapes and cultural characteristics were proposed.
