TAZ1 (TAPETUM DEVELOPMENT ZINC FINGER PROTEIN1; renamed from PEThy; ZPT3-2) cDNA was first isolated as an anther-specific cDNA from petunia. Here, we report a functional characterization that includes analysis of spatial and temporal expression profiles and examination of anther phenotypes in TAZ1-silenced plants. TAZ1 showed a biphasic expression pattern. In the premeiotic phase, TAZ1 transcri...

Anther culture is the most effective and not technically complex tool for obtaining double wheat haploids. The current study devoted to research of influence genotype concentration growth regulator 2.4-D on efficiency androgenesis in vitro spring bread wheat. purpose was estimate anther hybrids first second generation their parental varieties its dependence different concentrations 2.4-D. There...

The anthers in flowers perform important functions in sexual reproduction. Several recent studies used microarrays to study anther transcriptomes to explore genes controlling anther development. To analyze the secretion and other functions of the tapetum, we produced transcriptomes of anthers of rice (Oryza sativa subsp. japonica) at six progressive developmental stages and pollen with sequenci...

Rapeseed (Brassica napus L.) is an important oil crop worldwide and exhibits significant heterosis. Effective pollination control systems, which are closely linked to anther development, are a prerequisite for utilizing heterosis. The anther, which is the male organ in flowering plants, undergoes many metabolic processes during development. Although the gene expression patterns underlying polle...

Understanding the processes that underlie pollen release is a prime target for controlling fertility to enable selective breeding and the efficient production of hybrid crops. Pollen release requires anther opening, which involves changes in the biomechanical properties of the anther wall. In this research, we develop and use a mathematical model to understand how these biomechanical processes ...

Combination breeding and mutation are widely used methods in plant breeding. Intensive studies carried out on biotechnological that will allow obtaining homozygous lines a short time populations obtained with these two techniques. Numerous have been by different researchers wheat. There few anther culture response mutagen-treated genotypes. Two bread wheat promising advanced were as the materia...

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...

country in the world, facing great pressures regarding population growth, environmental deterioration and resource depletion, has ranked plant biology as one of its highest priorities since the early 1950s, especially in the area of agricultural development. Since plant biotechnology became available, it has developed rapidly in agriculture-related plant biology research. Two crucial innovation...
