Background: Cigarette smoke exposure is one of the source of free radicals that causes oxidative stress and decreases superoxide dismutase (SOD) level. Purple fleshed sweet potato is a type of food that contains antioxidants to neutralize oxidative stress.Objectives: To study the effect of purple fleshed sweet potato on superoxide dismutase (sod) level on rats exposed to cigarette smoke.Methods: This was a true experimental study with a post-test randomized control group design. The rats were randomized into 4 groups (6 rats in each group). The negative control group (K-) was treated with standard diet; the positive control group (K+) was treated with cigarette smoke exposure and standard diet; the treatment 1 (P1) group was treated with standard diet and purple fleshed sweet potato with the dose of 8 g / 200 g bw/day, and the treatment 2 (P2) group was treated with cigarette smoke exposure and purple fleshed sweet potato with the dose of 8 g /200 g bw/day.Results: There was a significant difference of SOD levels in each group (p=0.00) except between group K- and P1. Giving purple fleshed sweet potatoes increased SOD levels as much as 85.81±4.59 (P1). The K+ group had the lowest SOD level 22.34±3.98. The SOD level for K- group and P2 group was 82.27±4.59 and 67.73±6.68 respectively.Conclusion: The highest SOD level is on the treatment 1 group which is administered with purple fleshed sweet potato.

Purple Sweet Potato

An experiment was carried out to determine the effect of fermented purple sweet potato (Ipomoea batatas L) skin in diets on feed and anthocyanin consumption, carcass characteristics antioxidant profile and meat texture of Bali duck.. Five  treatment diets were used in a completely randomized design (CRD) consisted of control diet A (diet without containing purple sweet potato skin), diet B containing 10% purple sweet potato skin, diet C containing 10% fermented purple sweet potato skin, diet D containing 20% purple sweet potato skin, diet E containing 20% fermented purple sweet potato skin.Each treatment consisted of four replications and each replicate had five ducks. The variables observed were feed and anthocyanin consumption,slaughter weight, carcass weight, carcass percentage, carcass physical composition,  meat antioxidant profile (capacity antioxidant (CA), malondialdehide (MDA), and superoxide dismutase (SOD). Experiment results showed that diets with fermented or unfermented purple sweet potatoin diets treatments B, C, D, and E increased the anthocyanin  consumption,  slaughter weight, carcass weight, carcass percentage and meat percentage of duck carcass but decreased  their fat and skin. Fermented purple sweet potato (Ipomoea batatas L) skin  in  C and E increased the antioxidant capacity(AC)  and superoxide dismutase (SOD) while  treatment B and  D were not significantly different (P>0.05) to the control group.  Malondialdehide (MDA) of the duck meat in treatment B,C, and D were significantly lower (P<0.05) compared to the control diet. Treatment E significantly  increased the perimesium and endomesium of meat texture , but its experiment was not significantly different to the control group. It was concluded that substitution of fermented purple sweet potato (Ipomoea batatas L) skin in diets could improve of feed and anthocyanin, carcass characteristics, antioxidant profile, and meat texture of bali duck.

Abstract Background WRKY DNA-binding protein (WRKY) is a large gene family involved in plant responses and adaptation to salt, drought, cold and heat stresses. Sweet potato from the genus Ipomoea is a staple food crop, but the WRKY genes in Ipomoea species remain unknown to date. Hence, we carried out a genome-wide analysis of WRKYs in Ipomoea trifida (H.B.K.) G. Don., the wild ancestor of sweet potato. Results A total of 83 WRKY genes encoding 96 proteins were identified in I. trifida, and their gene distribution, duplication, structure, phylogeny and expression patterns were studied. ItfWRKYs were distributed on 15 chromosomes of I. trifida. Gene duplication analysis showed that segmental duplication played an important role in the WRKY gene family expansion in I. trifida. Gene structure analysis showed that the intron-exon model of the ItfWRKY gene was highly conserved. Meanwhile, the ItfWRKYs were divided into five groups (I, IIa + IIb, IIc, IId + IIe and III) on the basis of the phylogenetic analysis on I. trifida and Arabidopsis thaliana WRKY proteins. In addition, gene expression profiles confirmed by quantitative polymerase chain reaction showed that ItfWRKYs were highly up-regulated or down-regulated under salt, drought, cold and heat stress conditions, implying that these genes play important roles in response and adaptation to abiotic stresses. Conclusions In summary, genome-wide identification, gene structure, phylogeny and expression analysis of WRKY gene in I. trifida provide basic information for further functional studies of ItfWRKYs and for the molecular breeding of sweet potato.
