(Submitter supplied) To investigate the effect that biological nitrogen fixation will have on plant responses to nitrogen dose at elevated CO2, alfalfa (Medicago sativa) lines were grown at three nitrogen doses and ambient or elevated CO2. Four lines were used in the study, two lines that can form nodules capable of fixing nitrogen (effective lines) and two lines that can not form nodules capable of nitrogen fixation (ineffective lines). more...

(Submitter supplied) We studied the application of transcriptome technology in alfalfa selenium (Se) treatment. Alfalfa had different states after different concentrations of Se treatment. It shows that lower concentration promoted growth and higher concentration produced toxicity. The positive regulatory effects of moderate Se (100 mg / kg) on alfalfa was determined through preliminary experiments, and the gene expression of Alfalfa under this treatment was further analyzed by transcriptome.

(Submitter supplied) We conducted field surveys to detect the population density of the most important invasive weed species and their associated virus vectoring aphids in crops grown under high input (HIF) vs low-input (LIF) field conditions, with and without fertilizers and pesticides. The most frequent invasive weed species were Stenactis annua, Erigeron canadensis and Solidago canadensis. These species were hosts predominantly for the aphids Brachycaudus helichrysi and Aulacorthum solani in both management systems. more...

(Submitter supplied) Plant species posses a special set of genes functional only in arbuscular mycorrhizal symbiosis. So, the model plant Medicago truncatula (Jemalong 5) was used for transcriptome comparative analysis while infected with compatible rhizobia Sinorhizobium meliloti (strain 10) and with or without arbuscular mycorrhizal fungus Rhizophagus irregularis (SYM5). Whole shoot and whole root were used for RNA isolation and processed via one of the European certified Affymetrix core labs (http://core.img.cas.cz).

(Submitter supplied) Alfalfa (Medicago sativa L.) is a forage legume with significant agricultural value worldwide. MicroRNAs (miRNAs) are key components of post-transcriptional gene regulation and essentially control almost all aspect of plant growth and development. Although miRNAs have been reported from alfalfa but their expression profiles in different tissues and novel miRNAs as well as their targets have not been confirmed in this plant species. more...

(Submitter supplied) By comparing transcriptomes of tolerant and intolerant plants of sickle alfalfa subject to intensive animal grazing, we identified pathways involved in nutrient-responsive signaling, light and wound response, cell wall formation, and energy metabolism. In these pathways, grazing suppressed 39 genes, but less severe in the tolerant plant, and activated 5 genes all carrying polymorphisms in their homologous transcripts between the tolerant and intolerant plants. more...

(Submitter supplied) Polyploidization as the consequence of 2n gamete formation is a prominent mechanism in plant evolution. Studying its effects on the genome and its expression has both basic and applied interest. We crossed two diploid (2n=2x=16) M. sativa plants, a subsp. falcata seed parent and a coerulea x falcata pollen parent that produce a mixture of n and 2n eggs and pollen, respectively. Such cross produced full-sib diploid and tetraploid (2n=4x=32) progenies, the latter being the result of bilateral sexual polyploidization (BSP). more...
