Seed color is a key agronomic trait in crops such as peanut, where it is a vital indicator of both nutritional and commercial value. In recent years, peanuts with darker seed coats have gained market attention due to their high anthocyanin content. Here, we used bulk segregant analysis to identify the gene associated with the purplish-red coat trait and identified a novel gene encoding a basic/helix-loop-helix transcription factor, PURPLE RED SEED COAT1 (PSC1), which regulates the accumulation of anthocyanins in the seed coat.

Article Synopsis
  • Auxin response factors (ARFs) are key transcription factors in plants that regulate auxin response genes, critical for growth and development; this study focuses on identifying ARF genes in peanuts (Arachis hypogaea).
  • A total of 61 ARF genes were identified and categorized into six groups based on molecular analysis, revealing structural features like the B3 domain and specific auxin response domains; expression levels of these genes varied significantly across different peanut tissues.
  • Results indicated that certain ARF genes were highly expressed in stems and branches, and that their expression was affected by auxin treatment, with implications for pod development, particularly highlighting the role of one ARF in larger peanut pod formation

To assess relationships between xanthine oxidase (XOD) and nephropathogenic infectious bronchitis virus (NIBV) infection, 240 growing layers (35 days old) were randomly divided into two groups (infected and control) of 120 chickens each. Each chicken in the control and infected group was intranasally inoculated with 0.2 mL sterile physiological saline and virus, respectively, after which serum antioxidant parameters and renal XOD mRNA expression in growing layers were evaluated at 8, 15 and 22 days post-inoculation (dpi).

To identify the fuctions of the nine putative O-methyltransferase genes in Streptomyces virginiae IBL14, the evolutionary and functional relationship of these genes in its 8.0 Mb linear chromosome was set up via sequence comparison with those of other Streptomyces species. Further, the functions and catalytic mechanism of the three genes sviOMT02, sviOMT03 and sviOMT06 from this strain were studied through experimental and computational approaches.

Background: As well known, both natural and synthetic steroidal compounds are powerful endocrine disrupting compounds (EDCs) which can cause reproductive toxicity and affect cellular development in mammals and thus are generally regarded as serious contributors to water pollution. Streptomyces virginiae IBL14 is an effective degradative strain for many steroidal compounds and can also catalyze the C25 hydroxylation of diosgenin, the first-ever biotransformation found on the F-ring of diosgenin.

Results: To completely elucidate the hydroxylation function of cytochrome P450 genes (CYPs) found during biotransformation of steroids by S.
