Welfare and Management of Civets in Civet Coffee Tourism Plantations.

Civet coffee is produced with coffee beans that have passed through the digestive tract of civets which are then processed for drinking. Outlets, known as civet coffee tourism plantations are popular tourist attractions in Bali, Indonesia. These outlets keep caged civets for public viewing and sell civet coffee. We assessed civet welfare in 29 civet coffee tourism plantations to assess husbandry factors, the five freedoms and body condition scores. We also assessed civet welfare in eight wildlife markets where civets are sourced for civet coffee tourism and calculated turnover of civets. We found 99 civets in civet coffee tourism plantations and 136 in markets, where. Annually between 400 and 800 civets are sold. Welfare standards do not meet the Indonesian laws and regulations. Diet, hygiene, presence of water and mobility affected body condition scores and no civet met all of the five freedoms. Enforcement of welfare and trade laws is needed to improve civet welfare, and to curb the illegal civet trade. Tourists frequenting civet coffee tourism plantations should be made aware of the low welfare standards to inform their choice about supporting this industry.

RNAi trigger fragment truncation attenuates soybean FAD2-1 transcript suppression and yields intermediate oil phenotypes.

Suppression of the microsomal ω6 oleate desaturase during the seed development of soybean (Glycine max) with the 420-bp soybean FAD2-1A intron as RNAi trigger shifts the conventional fatty acid composition of soybean oil from 20% oleic and 60% polyunsaturates to one containing greater than 80% oleic acid and less than 10% polyunsaturates. To determine whether RNAi could be attenuated by reducing the trigger fragment length, transgenic plants were generated to express successively shorter 5' or 3' deletion derivatives of the FAD2-1A intron. We observed a gradual reduction in transcript suppression with shorter trigger fragments. Fatty acid composition was less affected with shorter triggers, and triggers less than 60 bp had no phenotypic effect. No trigger sequences conferring significantly higher or lower suppression efficiencies were found, and the primary determinant of suppression effect was sequence length. The observed relationship of transcript suppression with the induced fatty acid phenotype indicates that RNAi is a saturation process and not a step change between suppressed and nonsuppressed states and intermediate suppression states can be achieved.

An intron sense suppression construct targeting soybean FAD2-1 requires a double-stranded RNA-producing inverted repeat T-DNA insert.

We demonstrate that the transformation of soybean (Glycine max) with sense suppression constructs using intron sequences from the fatty acid oleyl Delta12 desaturase gene FAD2-1A leads to efficient and specific reduction of FAD2-1 transcripts in developing seeds, increased oleic acid, and decreased polyunsaturated fatty acids. The related FAD2-2 transcripts are only marginally affected. Despite screening a large number of independent transformants, no single-copy efficacious transformants could be found. Invariably, all the least complex transgenic loci have two T-DNA copies in an inverted repeat configuration, centered at the right borders. We show that this T-DNA configuration produces an inverted repeat transcript and that small interfering RNAs accumulate against the target sequence.
