(Submitter supplied) Pea (Pisum. sativum L.) is a traditional and important edible legume that can be sorted into grain pea and vegetable pea according to their harvested maturely or not. Vegetable pea by eating the fresh seed is becoming more and more popular in recent years. These two type peas display huge variations of the taste and nutrition, but how seed development and nutrition accumulation of grain pea and vegetable pea and their differences at the molecular level remains poorly understood. more...

(Submitter supplied) Purpose: Comprehensive comparison of gene-expression profiles between 3mlpa (mutant with low phytic acid) and 3MWT (non-mutant with normal phyic acid) soybean lines (Glycine max) at five stages of seed development using RNA-Seq approaches. Methods: mRNA sequencing reads (101SE) were generated in triplicate from five seed developmental stages of 3mlpa and 3MWT soybean line using Illumina HiSeq 2000. Results: A total of 4235 differentially expressed genes, including 512-transcription factor genes were identified. Eighteen biological processes such as apoptosis, glucan metabolism, cellular transport, photosynthesis and 9 transcription factor families including WRKY, CAMTA3 and SNF2 were enriched during seed development. Genes associated with apoptosis, glucan metabolism, and cellular transport showed enhanced expression in early stages of lpa seed development, while those associated with photosynthesis showed decreased expression in late developmental stages. Conclusion: This study provides a global perspective of transcriptomal changes during soybean seed development in 3mlpa mutant. The results suggest that low phtic acid-causing mutations in 3mlpa play a role in inducing and suppressing plant defense responses during early and late stages of seed development, respectively.

(Submitter supplied) Since chitooligosaccharides are water-soluble, biodegradable and nontoxic compounds, their application may be considered as a promising plant-protecting agent. However, the molecular and cellular modes of action of COs are not yet understood. Transcriptional changes in pea roots treated with COs were investigated via RNA sequencing. Pea roots treated with the deacetylated CO8-DA at low concentration (10-5 М) were harvested 24 h after treatment and their expression profiles were compared against medium-treated control plants. more...
