Soybean (Glycine max) is one of the most important agricultural commodities worldwide and a major protein and oil source. Herein, we identified the soybean ubiquitin-conjugating (E2) enzyme gene (GmUBC4; Glyma.18G216000), which is significantly upregulated in response to Anticarsia gemmatalis attack and Meloidogyne incognita-induced galls during plant parasitism by plant nematode. The GmUBC4 promoter sequence and its different modules were functionally characterized in silico and in planta using transgenic Arabidopsis thaliana and G. max lines. Its full-length transcriptional regulatory region (promoter and 5´-UTR sequences, named pUceS8.3 promoter) was able to drive higher levels of uidA (?-glucuronidase) gene expression in different tissues of transgenic A. thaliana lines compared to its three shortened modules and the p35SdAMV promoter. Notably, higher ?-glucuronidase (GUS) enzymatic activity was shown in M. incognita-induced giant cells when the full pUceS8.3 promoter drove the expression of this reporter gene. Furthermore, nematode-specific dsRNA molecules were successfully overexpressed under the control of the pUceS8.3 promoter in transgenic soybean lines. The RNAi gene construct used here was designed to post-transcriptionally downregulate the previously characterized pre-mRNA splicing factor genes from Heterodera glycines and M. incognita. A total of six transgenic soybean lines containing RNAi gene construct were selected for molecular characterization after infection with M. incognita pre-parasitic second-stage (ppJ2) nematodes. A strong reduction in the egg number produced by M. incognita after parasitism was observed in those transgenic soybean lines, ranging from 71 to 92% compared to wild-type control plants. The present data demonstrated that pUceS8.3 is a gene promoter capable of effectively driving dsRNA overexpression in nematode-induced giant cells of transgenic soybean lines and can be successfully applied as an important biotechnological asset to generate transgenic crops with improved resistance to root-knot nematodes as well as other pests.

Seven bee pollen samples (C1?C7) with different palynological sources were harvested from Pindamonhangaba municipality (Southeast Brazil). Methanol extracts of untreated samples (control), samples frozen at −18 °C and samples frozen and then dried were analyzed by HPLC/PAD/ESI/MS/MS. Flavonoid diglycosides of quercetin, kaempferol, isorhamnetin and patuletin were detected, together with hydroxycinnamic acid amide derivatives, such as N′,N′′,N′′′-tris-p-feruloylspermidine and N′,N′′,N′′′-tris-p-coumaroylspermidine. Distinct phenolic profiles characterized the analyzed samples, but no differences were noted as resulting from different treatments. Total phenolic contents determined with the Folin?Ciocalteau reagent ranged from 1.7 to 2.2%. Antioxidant activities above 75%, based on the DPPH method, were observed for all extracts, not correlated with total phenolic contents. Among samples from the same origin, those frozen were more active than samples untreated (control), and the samples frozen and then dried were the most active. |
