This study was carried out to determine the effects of genotype and media on haploid plant formation 12 pepper genotypes (Capsicum annuum L.) via in vitro anther culture. The buds were cultured 2 different (O1 O2) and, results revealed that had development anthers, embryo plantlet initiation. When developmental status is examined, lowest value obtained from SU-31 with 2.47%, while cv. Flinta F1...
Albinism in plants is characterized by partial or complete loss of chlorophyll pigments and incomplete differentiation chloroplast membranes. This a very common problem encountered interspecific crosses tissue culture experiments including anther generation doubled haploids. impairs photosynthesis the eventually die at young stage without reaching maturity. Environmental conditions such as ligh...
The near absence of cell movement in plants makes clonal analysis a particularly informative method for reconstructing the early events of organ formation. We traced the patterns of cell division during maize anther development by inducing sector boundaries that preceded the earliest events of anther initiation. In doing this, we were able to estimate the smallest number of cells that are fated...
The male gametophyte and tapetum play different roles during anther development although they are differentiated from the same cell lineage, the L2 layer. Until now, it has not been possible to delineate their transcriptomes due to technical difficulties in separating the two cell types. In the present study, we characterized the separated transcriptomes of the rice microspore/pollen and tapetu...
Apposite development of anther and its dehiscence are important for the reproductive success of the flowering plants. Recently, bHLH142, a bHLH transcription factor encoding gene of rice has been found to show anther-specific expression and mutant analyses suggest its functions in regulating tapetum differentiation and degeneration during anther development. However, our study on protein level ...
Scented rose species are very important in the genus Rosa due to their use in highly-prized essential oil production and as garden roses. The fragrance of the rose flower (attar) captured by extraction is one of the most valuable flavor and fragrance products. A comprehensive study of the papers published in the field of in vitro culture and biotechnology of these species, particularly Damask r...
