Potential of a mutant-based reverse genetic approach for functional genomics and molecular breeding in soybean

Mutant-based reverse genetics offers a powerful way to create novel mutant alleles at a selected locus. This approach makes it possible to directly identify plants that carry a specific modified gene from the nucleotide sequence data. Soybean [Glycine max (L.) Merr.] has a highly redundant paleopolyploid genome (approx. 1.1 Gb), which was completely sequenced in 2010. Using reverse genetics to support functional genomics studies designed to predict gene function would accelerate post-genomics research in soybean. Furthermore, the novel mutant alleles created by this approach would be useful genetic resources for improving various traits in soybean. A reverse genetic screening platform in soybean has been developed that combines more than 40,000 mutant lines with a high-throughput method, Targeting Local Lesions IN Genome (TILLING). In this review, the mutant-based reverse genetic approach based on this platform is described, and the likely evolution of this approach in the near future.

Three Turns of Contemporary Architecture and the Chinese Traditional Thoughts

Significant changes have taken place within the contemporary architecture since the 20th century: firstly the architecture turns from "thing" to "nothing",secondly the experience of architecture turns from logic to essence intuition,and thirdly the architecture turns from noun to verb,from which we find in surprise the sparks of the Chinese traditional thought which criticizes all the ready-made,especially the conceptual thought with its happening and generation,and shows a new non-subject-object-dimidiate,non-logical and fundamentally non-metaphysical perspective in theory.This made it possible for us to reconsider and reinterpret the contemporary architecture from a more original new perspective.
