The ethanol extracts of Opuntia ficus-indica fructus (EEOF) and Opuntia ficus-indica stem (EEOS) were prepared and used to evaluate the pharmacological effects of cactus. Both the extracts inhibited the writhing syndrome induced by acetic acid, indicating that they contains analgesic effect. The oral administrations of EEOF and EEOS suppressed carrageenan-induced rat paw edema and also showed potent inhibition in the leukocyte migration of CMC-pouch model in rats. Moreover, the extracts suppressed the release of $\beta$-glucuronidase, a lysosomal enzyme in rat neutrophils. It was also noted that the extracts showed the protective effect on gastric mucosal layers. From the results it is suggested that the cactus extracts contain anti-inflammatory action having protective effect against gastric lesions.

A new isolate of rod-shaped virus was identified from grafted cactus, Gymnocalycium mihanovichii grafted onto Hylocereus trigonus, in Korea. The virus proved to be a new Tobamovirus and called previously as Tobamovirus-Ca for which we suggest the name Cactus mild mottle virus(CMMoV), because it produced systemic mild mosaic symptoms on its original host. CMMoV is distantly related to known species of the genus Tobamovirus on the basis of host range, serological and sequence analyses. Western blot analysis showed that CMMoV is serologically unrelated to Summons' Opuntia virus which is the only known species of the genus found in cactus plants. The 3'-terminal 2,910 nucleotides have been sequenced for the virus. The coat protein (CP) and movement protein (MP) genes encode 161 and 306 amino acids residues, respectively. The nucleotide and amino acid sequences of the CP were 39.6 ％ to 49.2 ％ and 26.4 ％ to 40.3 ％ identical to other tobamoviruses, respectively. The MP and 3' noncoding region shared 16.3 ％ to 23.3 ％ and 44.6 ％ to 63.4 ％ identities, respectively, with the members of the genus. Phylogenetic tree analysis of the CP gene revealed that CMMoV clusters with members of subgroup I of Tobamovirus. CMMoV particles contained genomic RNA along with two subgenomic RNAs, and this characteristics is common in the members of the subgroup II. This is the first information of sequence and comparative analysis of a Tobamovirus that infects cactus.

In order to better understand the quality of Korean cactus, Opuntia humifusa, as the functional foodstuffs, it's seeds, stems and fruits were analyzed. In addition, we performed quality evaluation on cookies manufactured with cactus powder added. The results showed the soluble nitrogen-free component levels in the cactus to be very high. The highest component levels were crude fiber(48.75%) and crude fat(7.38%) in the seeds, crude ash(15.39%) in the stems, and moisture(11.26%) and crude protein(8.79%) in the fruits. The antioxidant activities of the cactus were evaluated based on peroxide values(POV), thiobarbituric acid reactive substances(TBARS value), and electron donating ability(EDA) using the DPPH method. The POVs for soybean oil containing a 0.05% concentrated water extract from each part of the cactus revealed a remarkable antioxidant effects on peroxidation as storage time increased. The TBA values were 63.65% in BHT, 60.67% in the stems, 57.31% in the fruits and 49.16% in the seeds. The EDAs were 30.26% in the stems, 25.89% in the fruits, and 25.65% in the seeds. The total polyphenol contents of the water soluble materials from the cactus were 3.14 g/100 g in the fruits, 2.93 g in the stems and 2.11 g in the seeds. For the cookies, as the amounts of fruit and stem powder increased, the spreadness was significantly lowered, but moisture content was increased compared to the control. The color degree of the cookies changed from dim to intense as more fruit powder was added, resulting from a decrease in the L- and b-values and a significantly increased a-value. With the addition of stem powder, the L- and a-values revealed no significant differences, while the b-value was lowered compared to the control as more stem powder added. For texture changes of the fruit cookies, there were significant differences in hardness, gumminess, cohesiveness, springiness and brittleness. The stem cookies, however, showed only differences in hardness, gumminess, and brittleness, and not in cohesiveness and springiness. Finally, an overall sensory preference was found with the 1% fruit powder and 3% stem powder additions.

Objective: This study ascertained effects of cactus pear in association with different roughage in the diet of F1 Holstein/Zebu cows on intake, nutrient digestibility, nitrogen balance, ingestive behavior and performance. Methods: Eight cows with $72{\pm}11$ days of lactation were used. The experimental design was simultaneous in two $4{\times}4$ Latin squares. Four experimental diets were used: Diet 1, sorghum silage as exclusive roughage; Diet 2, sorghum silage associated with cactus pear in a proportion of 50% of the roughage (dry matter basis); Diet 3, elephant grass (Pennisetum purpureum cv. Roxo) as exclusive roughage; Diet 4, elephant grass associated with cactus pear in a proportion of 50% of the roughage. The roughage:concentrate ratio was 75:25. Results: Dry matter intake (p = 0.01) was higher with sorghum silage. There were differences in dry matter intake (p = 0.01), crude protein (p<0.01), ether extract (p = 0.01), non-fibrous carbohydrates (p<0.01) and total digestible nutrients (p = 0.01) among the diets. Cactus pear in the diet reduced water intake by 44.52% (p<0.01). The nitrogen balance was 59.71% and 27.49% lower in animals treated with exclusive sorghum silage and sorghum silage associated with cactus pear in relation to diets with elephant grass and elephant grass associated with cactus pear, respectively (p<0.01). The diets did not influence the milk production (p = 0.70), 3.5% fat corrected milk production (p = 0.72) or feed efficiency (p = 0.61). Conclusion: The association of cactus pear with sorghum or elephant grass silage does not alter milk production, reduces the intake of dry matter and water and improves the digestibility of nutrients.

제주 선인장군락지는 동아시아 지역에서 식물지리학적으로 특이적인 분포를 보이고 있으며, 국내 유일한 자생지로 특유의 고유경관을 형성하고 있다. 그럼에도 불구하고 자생지 일대의 선인장 분포 현황에 관한 정밀조사가 이루어진 바 없으며, 서식지 내 혼생식물의 다양성 및 선인장 개체군 분포와의 상호 관계에 관한 조사가 이루어진 바 없다. 본 연구는 월령리 선인장군락지 내 관속식물의 다양성을 파악하고 선인장의 분포 실태 및 출현 경향을 기록하고자 하였다. 선인장의 분포 특성과 함께 혼생 식물종 가운데 서식처의 특성을 반영하는 종의 특성과 선인장 개체군의 유지에 위협이 되거나, 선인장 보존에 있어서 관리의 대상이 되는 생물 및 환경 요소에 관하여 논의하고자 한다. 식물상 확인을 위한 현장조사는 2015년 6월부터 2017년 9월까지 식물계절을 고려하여 총 6회에 걸쳐 이루어졌다. 식물에 대한 배열순서와 학명의 기재는 Engler 분류체계에 따라 정리하였으며, 종의 한글명은 한국표준식물목록을 채택하였다. 연구결과 제주 월령리 선인장군락지는 선인장이 우점하는 지역 고유의 특징적인 상관을 형성하고 있었다. 관속식물상은 53과 104속 109종 15변종 1품종으로 총 125분류군을 확인하였다. 환경부 지정 멸종위기식물은 분포하지 않았다. 양치식물은 꼬리고사리, 도깨비쇠고비로 2종이 확인하였으며, 나자식물은 서식하지 않았다. 피자식물이 총 123분류군이 나타났으며, 쌍자엽식물이 91분류군, 단자엽식물이 32분류군으로 밝혀졌다. 선인장 보호지역 내 전체 487개 격자 중 59.3%에 해당하는 289개 격자에서 선인장 분포를 확인하였으며, 5-95%의 다양한 피도분포를 보였다. 미출현 격자의 대부분은 현무암 암반이 노출된 해안지역으로, 반복적인 파도의 영향을 받아 토심이 발달하지 못하거나 극히 제한적인 지역과 인위적 시설물 또는 초지, 관찰로 등이 조성된 지역이었다. 반면 선인장이 70% 이상 높은 우점도를 보이는 구간은 총 71개 격자 지점으로 전체의 14.5%를 차지하고 있었다. 선인장은 보호 지역 내에서 무작위분포를 나타내며, 미소서식처 환경에 적응되어 생육가능입지를 따라 기회주의적으로 분포하고 있는 것으로 확인되었다. 군락지 내 선인장은 대부분 단위생식(parthenogenesis)에 의존되어 있음을 고려할 때 현재의 분포는 군락지 내 선인장의 잠재분포가능 영역을 투영하는 결과로 판단된다. 현장조사결과를 바탕으로 보호지역 보존 및 보호를 위한 관리방안을 제안하였다.

A total of 62 isolates of Bipolaris cactivora causing cactus stem rots were isolated from major cactus-growing areas in Korea. Colony morphology of the isolates on potato-dextrose agar was differentiated into aerial (CA) and non-aerial mycelial types (CB). CA had profound aerial mycelium with grayish brown (CA-l), light brownish (CA-2), and brownish (CA-3) pigmentations; respectively, while CB had dark brownish pigmentations. CA had conidia of less dark pigmentation and acute terminal end. CB had darker and more round-end conidia. Twenty-eight amplified fragments were produced by polymerase chain reaction (PCR) with a set of 2 random primers. The sizes of amplified DNA fragments ranged approximately from 0.1 to 2.3 kb. The isolates were classified into 2 major genomic DNA random amplified polymorphic DNA (RAPD) groups at the genomic similarity of 97.7％ and 95.1％, respectively. Cluster analysis of genetic similarity among the isolates generated a dendrogram that clearly separated all isolates into SA or SB. This result suggests that there may be two morphotypes of B. cactivora in Korea that may differ in their genetic constitutes.

Co-infection with two virus species was previously reported in some cactus plants. Here, we showed that Notocactus leninghausii f. cristatus can be co-infected with six different viruses: cactus mild mottle virus (CMMoV)-Nl, cactus virus X (CVX)-Nl, pitaya virus X (PiVX)-Nl, rattail cactus necrosis-associated virus (RCNaV)-Nl, schlumbergera virus X (SchVX)-Nl, and zygocactus virus X (ZyVX)-Nl. The coat protein sequences of these viruses were compared with those of previously reported viruses. CMMoV-Nl, CVX-Nl, PiVX-Nl, RCNaV-Nl, SchVX-Nl, and ZyVX-Nl showed the greatest nucleotide sequence homology to CMMoV-Kr (99.8% identity, GenBank accession NC_011803), CVX-Jeju (77.5% identity, GenBank accession LC12841), PiVX-P37 (98.4% identity, GenBank accession NC_024458), RCNaV (99.4% identity, GenBank accession NC_016442), SchVX-K11 (95.7% identity, GenBank accession NC_011659), and ZyVX-B1 (97.9% identity, GenBank accession NC_006059), respectively. This study is the first report of co-infection with six virus species in N. leninghausii f. cristatus in South Korea.
