Project description:Soybean aphids are phloem-feeding pests that can cause significant yield losses in soybean plants. Soybean aphids thrive on susceptible soybean lines but not on resistant lines. Aphids do not normally kill their host and colonize plants for long periods of time, up to several months in soybean. However, our knowledge of plant responses to long-term aphid colonization is very limited. We used microarrays to characterize the soybean plant's transcriptional response against aphids in two related cultivars, a susceptible line and a resistant line with the Rag1 aphid-resistance gene. We measured transcript levels in leaves after 21 days of aphid infestation.
Project description:To explore the mechanism underlying antioxidant activity of extracts from black soybean sprouts 0.5 cm long, Agilent-016772 G. max (Soybean) Oligo Microarray 4x44K was used to compare mRNA expression between the black soybean sprouts 0.5 cm long (n=4) and the black soybean sprouts 5 cm long (n=4). GO term enrichment analysis showed ten up-regulated genes (BE823689.1_567, GMFL01-02-F14-R_381, GMFL01-03-G22-R_364, GMFL01-14-M12-R_553, GMFL01-51-M23-R_265, AW757007.1_297, AW761420.1_260, BI788389.1_501, BQ273202.1_332 and GMFL01-10-I14-F_701) in the 0.5 cm seedlings were associated with response to oxidative stress. qRT-PCR assay confirmed the up-regulation of these ten genes in sprouts 0.5 cm long. In conclusion, these ten genes may contribute to antioxidant activity of sprout extract. Gene expressions in black soybean sprouts were measured using Agilent-016772 G. max (Soybean) Oligo Microarray 4x44K. Four independent experiments were performed in each group using different sprout sample.

Project description:GmMYB176, an R1 MYB transcription factor regulates isoflavonoid biosynthesis in soybean. In the current experiment, GmMYB176 was silenced (GmMYB176-Si) or overexpressed (GmMYB176-OE) in soybean hairy roots and their effect on transcriptome was studied. RNA-Seq analyses of GmMYB176-Si and GmMYB176-OE along with control non-transformed soybean hairy roots revealed that alteration of gene expression of GmMYB176 affects gene regulation of hundreds of genes in soybean.
Project description:Alcoholic fatty liver disease (AFLD) is a liver disease closely related to long-term alcohol consumption. Although it is known that liver microsomal cytochrome P450 enzyme (CYP450) plays a crucial role in metabolizing alcohol and various exogenous compounds, the specific mechanism by which alcohol affects the activity and expression of CYP450 enzyme is still not fully understood. In addition, existing research mainly focuses on the effects of short-term alcohol exposure, and the understanding of how long-term alcohol intake changes CYP450 enzyme function and expression is still insufficient. Therefore, this study aims to explore the effects of long-term alcohol intake on CYP450 enzyme activity through an AFLD rat model, fill the gap in existing research, reveal the specific effects and possible molecular mechanisms of long-term alcohol consumption on liver CYP450 enzyme activity and expression, and provide new insights for developing treatment strategies for AFLD.
