Evaluation of Resistance to Phytophthora sojae in Soybean Mini Core Collections Using an Improved Assay System.

Stem and root rot disease caused by Phytophthora sojae is devastating to soybean crops worldwide. Developing host resistance to P. sojae, considered the most effective and stable means to control this disease, is partly hampered by limited germplasm resources.

Improvement of the Oryza sativa Nipponbare reference genome using next generation sequence and optical map data.

Background: Rice research has been enabled by access to the high quality reference genome sequence generated in 2005 by the International Rice Genome Sequencing Project (IRGSP). To further facilitate genomic-enabled research, we have updated and validated the genome assembly and sequence for the Nipponbare cultivar of Oryza sativa (japonica group).

Results: The Nipponbare genome assembly was updated by revising and validating the minimal tiling path of clones with the optical map for rice.

Deregulation of sucrose-controlled translation of a bZIP-type transcription factor results in sucrose accumulation in leaves.

Sucrose is known to repress the translation of Arabidopsis thaliana AtbZIP11 transcript which encodes a protein belonging to the group of S (S--stands for small) basic region-leucine zipper (bZIP)-type transcription factor. This repression is called sucrose-induced repression of translation (SIRT). It is mediated through the sucrose-controlled upstream open reading frame (SC-uORF) found in the AtbZIP11 transcript.
