Available in PDF, EPUB and Kindle. Book excerpt: Crop improvement using classically induced mutagenesis is now well standardized. Many new promising varieties of different crops have been successfully developed worldwide using both physical and chemical mutagens. Voluminous literature is now available on basic and applied aspects of mutagenesis. The mutation technique has been refined and holds the promise of generating much wider and more desirable variability than classical breeding. Recent advances in technology combined with classical mutation breeding offer new and exciting challenges for the development of new varieties. A global inventory of induced mutagenesis activities for crop improvement is requried. This book covers both basic and applied aspects of mutation and its impact on various crops: it is extremely well prepared and contains a huge volume of information accumulated using classically induced mutagenesis on different crops in different countries. Three key features: Describes the importance of induced mutation in crop plant research and its application to production Highlights new advances in the understanding of plant mutagenesis in crop improvement Contains contributions from major leaders in the field of plant mutation research This volume brings together all the important and relevant literature in the field. It provides a complete account of the mutation breeding of crops, presenting conclusions about the value of the method, its possibilities, limitations, and shortcomings, and the possible difficulties of further application in various crops. The initial chapters deal with the interactions between mutagenic treatment and plant material, such as aspects of mutagenic treatment, postirradiation behavior of shoot apices, and adventitious bud techniques. All available literature is then discussed crop by crop and critically evaluated. This will serve as an extremely comprehensive guide for researchers, teachers, students, and individuals who are interested in using induced mutagenesis as a tool for crop improvement.

Download or read book The effect of sulfur deficiency in pea Pisum sativum on factors related to nitrogen fixation and on sulfate transporters written by Parisa Pourmoayyed and published by Cuvillier Verlag. This book was released on 2016-07-25 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sulfur has a vital role in the plant life cycle. S deficiency reduces optimal yield and quality in legumes which lead to a reduction in nutritional value of food and feed. S deficiency also alters the symbiotic interaction between leguminous plants and soil nitrogen fixing bacteria which leads to a decline in N2 fixation rate. An efficient symbiotic nitrogen fixation (SNF) in the nodule demands a strong nutrient exchange between plant and bacterial cells. The plant symbiotic sulfate transporter (SST) supports adequate S supply for full activity of nodules. In the present study, I investigated how different levels of S supply affect the protein and mRNA expression of genes related to N2 fixation in Pisum sativum. Moreover, different sulfate transporter genes were identified in pea and the functional analysis was performed for the symbiotic sulfate transporter from pea after expression in yeast double mutant. Growth retardation was observed in both weak and severe S deficient plants while severe S deficiency led to a significant decline in total biomass and shoot dry weight. Chlorosis and yellowish leaves in severe S deficient plant were observed as a consequence of a 43% decline in the chlorophyll content of young leaves in comparison with the control plants. Both weak and severe S deficiency reduced nodule formation. Thus, nodules appeared smaller and green with less leghemoglobin content in the S deficient groups. Relative transcript abundance of leghemoglobin genes (PsLb5 and PsLb120) did not change significantly under S deficiency conditions in the vegetative phase, thus confirming that expression of both genes is essential to create a low O2 concentration in young nodules. In contrast, severe S deficiency during the generative phase reduced expression of leghemoglobin at mRNA and protein levels. Furthermore, the higher leghemoglobin content in the generative phase is indicative for a higher leghemoglobin demand of mature nodules to maintain a low O2 environment and to protect the nitrogenase for an effective SNF. Nitrogenase is encoded by the nifHDK gene cluster. Severe S deficiency reduced the relative transcript abundance of the β subunits (NifK gene) while expression of α subunits (NifD gene) was mostly unaffected. S deficiency conditions increased relative transcript abundance of ferredoxin to compensate the S limitation in the nodule. Furthermore, a higher level of ferredoxin expression in the generative phase compared to the vegetative phase might be accompanied by a more SNF activity in the generative phase. In contrast to the nodule, relative ferredoxin transcript abundance was reduced under severe S deficiency in the root and leaf tissues supporting sulfite reduction and NADP photo-reduction. Both severe and weak S deficiencies reduced the relative transcript abundance of ferredoxin in the young leaves more than the mature leaves because the mature leaves are the main site of sulfate storage and assimilation. Severe S deficiency reduced expression of the nodule-specific sulfate transporter (SST) in both vegetative and generative phase of plant life which confirms a disruption in sulfate transport in symbiosomes. Phylogenetic analysis of 14-full length sulfate transporter sequences from pea and other known sulfate transporters from the leguminous family revealed that they fall into five major groups. In conclusion, a reduced sulfate import into the nodule probably reduces the sulfate related metabolites and interrupts the expression and biosynthesis of nitrogenase, leghemoglobin and ferredoxin proteins and eventually leads to an interruption of SNF. Moreover, severe S deficiency could limit the S compounds and S containing amino acids essential for the synthesis of critical products such as chlorophyll, thus leading to a lower rate of photosynthesis and fewer energy sources for an efficient yield.
