When initial true leaves of 1-month postemergence Acala SJ-2 cotton plants were wounded by gentle abrasion, accumulations of ferulic acid (4-hydroxy-3-methoxycinnamic acid) were detected on the 3rd and 4th days after treatment. When similar wounds were immediately treated with cell-free extracts of Aspergillus flavus mycelia, elevated levels of scopoletin (6-methoxy-7-hydroxycoumarin) were produced, beginning 1 day after treatment and continuing for 7 days. Elevated levels of scopoletin were not detected in leaves that were only wounded, and enhanced quantities of ferulic acid were not observed in leaf tissue after wounding and exposure to the fungal extract. Accumulations of these compounds were not apparent in nonwounded controls. The results demonstrate a wound response distinct from the wound – fungal extract reaction.

Allotetraploid Cotton

Abstract Background An evolutionary model using diploid and allotetraploid cotton species identified 80 % of non-coding transcripts in allotetraploid cotton as being uniquely activated in comparison with its diploid ancestors. The function of the lncRNAs activated in allotetraploid cotton remain largely unknown. Results We employed transcriptome analysis to examine the relationship between the lncRNAs and mRNAs of protein coding genes (PCGs) in cotton leaf tissue under abiotic stresses. LncRNA expression was preferentially associated with that of the flanking PCGs. Selected highly-expressed lncRNA candidates (n = 111) were subjected to a functional screening pilot test in which virus-induced gene silencing was integrated with abiotic stress treatment. From this low-throughput screen, we obtained candidate lncRNAs relating to plant height and tolerance to drought and other abiotic stresses. Conclusions Low-throughput screen is an effective method to find functional lncRNA for further study. LncRNAs were more active in abiotic stresses than PCG expression, especially temperature stress. LncRNA XLOC107738 may take a cis-regulatory role in response to environmental stimuli. The degree to which lncRNAs are constitutively expressed may impact expression patterns and functions on the individual gene level rather than in genome-wide aggregate.

Methoxycinnamic Acid

The effect of modification with transglutaminase (TGase) and 4-hydroxy-3-methoxycinnamic acid (ferulic acid) on properties of tilapia skin gelatin film (TSGF) was researched. The results showed that the peroxide inhibition of modified TSGF increased from 14.7% to 62.0% and 52.1%, when concentrations of TGase and ferulic acid were 0.20 or 1.0 mg·mL-1. At the same time, the WVP coefficients were lower about 24.2% and 20.6%, respectively. The solubility of TSGF decreased with the increase in concentration of TGase and ferulic acid. As the formation of hydrogen bonds in the structure of the film, the amide A band was shifted towards higher wave numbers after modification.

Subsequent Degradation

Simultaneous treatment with certain carbamate insecticides inhibited degradation of 3-(p-chlorophenyl)-1,1-dimethyrurea (monuron) in cotton (Gossypium hirsutumL.) leaf discs. Monuron degradation was strongly inhibited by 1-naphthyl methylcarbamate (carbaryl) and 4-benzothiophene-N-methylcarbamate, but 2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate was ineffective. Effective carbamates did not prevent the metabolism of monuron to 1-(p-chlorophenyl)-3-methylurea (hereinafter referred to as monomethylmonuron), but they inhibited subsequent degradation of monomethylmonuron.

Isoferulic acid (3-hydroxy-4-methoxycinnamic acid, IFA), the isomer of ferulic acid (4-hydroxy-3-methoxycinnamic acid), is a rare phenolic acid occurring in Rhizoma Cimicifugae. Unlike ferulic acid, which has been well investigated, the antioxidant activity of IFA has not been measured. In this study, IFA was systematically evaluated for its in vitro antioxidant activity for the first time. IC50 values were calculated of 7.30±0.57, 4.58±0.17, 1.08±0.01, 8.84±0.43, 7.69±0.39, 1.57±0.2, 13.33±0.49 μg/mL, respectively, for lipid peroxidation, DPPH (1,1-diphenyl-2-picrylhydrazyl radical) and ABTS (3-ethylbenzthiazoline-6-sulfonic acid diammonium salt) radical scavenging, reducing power on Fe3+ and Cu2+ ions, and hydroxyl and superoxide anion radical scavenging. Comparison with the IC50 values with those of the positive controls, Trolox and butylated hydroxyanisole (BHA), it can be concluded that isoferulic acid is an effective natural antioxidant in both lipid and aqueous media.
