Abstract
The study was conducted to evaluate the status of anthelmintic resistance in Gastro-Intestinal Nematodes (GINs) of goats at an organized farm located in Kashmir, as there is no report of resistance against these parasites of goats from this temperate region, although it has been reported worldwide including India. Caprines reared at this farm exhibited reduced efficacy to multiple anthelmintics following treatments with Fenbendazole (FBZ), Closantel and Ivermectin (IVM) in Faecal Egg Count Reduction Test (FECRT). The results suggested that the overall efficacy was highest for IVM at 83.5% and 90.0% on 7th and 14th day post-treatment, respectively and least for FBZ at 44.3% and 62.5%, respectively, whereas the corresponding figures for closantel were 68.3% and 86.2%, respectively. The pre-treatment faecal culture revealed Haemonchus contortus, Teladorsagia circumcincta and Trichostrongylus colubriformis as predominant strongyles, however, in post-treatment samples, only H. contortus was observed. Further, the infective larvae were subjected to Allele specific PCR (AS-PCR) for accurate diagnosis of BZ resistance. The AS-PCR revealed 52% of H. contortus were homozygous resistant (rr) and 17% were heterozygous (rS) on day “0” before treatment and 100% homozygous resistant (rr) on 7th day post treatment. In both T. colubriformis and T. circumcincta, 100% population was homozygous susceptible (SS) at day “0” before treatment. The overall frequency of resistant (r) allele for H. contortus was 60.5% and for susceptible allele (s) was 39.5%. For T. colubriformis and T. circumcincta the frequency of susceptible allele (s) was 100%. The survey indicated that the GINs of goats on the farm have developed multiple anthelmintic resistance to FBZ, closantel and IVM and the condition is alarming in the farm. Moreover surveillance studies about status of anthelmintic resistance in other farms (Govternment as well as Private) of Kashmir valley should be carried out at large scale to develop effective and sustainable control strategies against GI Nematodes.

Abstract
Three trials were conducted to evaluate the therapeutic efficacy of closantel (@ 7.5 mg/kg body weight, orally), fenbendazole (@ 7.5 mg/kg body weight, orally) and ivermectin bolus (@ 0.2 mg/kg body weight, orally) against gastrointestinal (GI) helminth parasites of cattle in central zone of Kashmir valley. Twenty cattle suffering from GI helminth infection were randomly selected and divided into two groups in each trial. In each trial, one group comprising of fifteen animals were treated with anthelmintic and second group comprising of five animals were kept as infected untreated control. To determine the therapeutic efficacy of different anthelmintic drugs against GI helminths, faecal samples were directly collected from rectum before treatment and on 7th, 14th and 28th day post treatment and eggs per gram of faeces was determined by using Stoll's method. Then the efficacy of different anthelmintics was calculated by employing Faecal Egg Count Reduction Test. On 14th day post treatment closantel was found to be 100 and 94.44% effective against Fasciola spp. and strongyle worms, respectively, however, it was not found effective against Trichuris spp. The efficacy of fenbendazole was 100% against Fasciola spp., paramphistomes, Moniezia spp., Trichuris spp. and strongyle worms on 14th day post treatment. Ivermectin was found to be 100% effective against Trichuris spp. and strongyle worms on 14th day post treatment, however, it was not effective against Fasciola spp. and paramphistomes.

Abstract
Crocus sativus is the only plant species which produces apocarotenoids like crocin, picrocrocin and safranal in significant amounts. These compounds impart organoleptic properties to saffron (dried stigmas of Crocus flower) making it world’s costliest spice. Crocus apocarotenoids have tremendous medicinal properties as well. Effect of endophytes on Crocus apocarotenoid production and the molecular mechanism involved has not been reported so far. Here we studied the effect of an oleaginous fungal endophyte, Mortierella alpina CS10E4 on Crocus growth, apocarotenoid metabolism and tolerance to corm rot disease. The results demonstrated that there was a significant improvement in many morphological and physiological traits in endophyte treated Crocus plants including total biomass and size of corms, stigma biomass, number of apical sprouting buds, and number of adventitious roots. The endophyte also shifted metabolic flux towards enhanced production of apocarotenoids by modulating the expression of key pathway genes. Further, M. alpina CS10E4 enhanced tolerance to corm rot disease by releasing arachidonic acid which acts as conserved defense signal and induces jasmonic acid production in endophyte treated Crocus corms. This is first report on effect of a fungal endophyte on Crocus apocarotenoid metabolism and stress tolerance.

Prevalence study on GastroIntestinal (GI) helminths of goats was carried out at Govt. Farms of twin districts of Bandipora and Ganderbal and locally reared goats of district Baramulla of the Kashmir Valley over a period of one year from December 2011 to November 2012. A total of 1016 faecal samples were examined which revealed overall prevalence of GI helminths to be 74.70%, with platyhelminths and nemathelminths in 14.76 and 70.07% animals, respectively. The helminths recorded in the present study were Fasciola spp. (2.75%), Dicrocoelium spp. (3.44%), paramphistomes (3.05%), Moniezia spp. (9.44%), strongyle worms including Nematodirus spp. (68.30%), Strongyloides spp. (5.90%) and Trichuris spp. (4.29%). On coprocultural examination Haemonchus spp. (71.05%) was found to be the most predominant strongyle worm followed by Trichostrongylus spp. (12.86%), Chabertia spp. (8.47%) and Ostertagia spp. (7.62%). Seasonal prevalence of GI helminths was observed highest in summer (78.03%) followed by spring (75.39%), winter (74.90%) and autumn (70.47%), the difference being statistically non-significant (P > 0.05). The prevalence of platyhelminths was found to be non-significantly higher in winter (20.00%) followed by spring (15.07%), summer (12.54%) and autumn (11.41%). Nemathelminths were recorded highest in summer (75.68%) followed by spring (71.82%), autumn (68.50%) and winter (64.31%). EPG ranged from 0 to 1500 and an average EPG count was found to be 312.7 ± 17.76. EPG was found to be highest in summer (453.80 ± 45.25) followed by spring (313.2 ± 28.76), autumn (256.1 ± 17.48) and winter (190.2 ± 32.0).Overall prevalence of GI helminths was found more in adult goats (77.85%) compared to young ones (67.42%), the difference being statistically significant (P < 0.05). Similarly, it was found to be higher in females (75.89%) as compared to males (66.12%) and the variation being statistically non-significant (P > 0.05).

Abstract
A total of 294 fungal endophytes were isolated from the corms of Crocus sativus at two stages of crocus life cycle collected from 14 different saffron growing sites in Jammu and Kashmir (J & K) State, India. Molecular phylogeny assigned them into 36 distinct internal transcribed spacer (ITS) genotypes which spread over 19 genera. The diversity of endophytes was higher at the dormant than at the vegetative stage. The Saffron microbiome was dominated by Phialophora mustea and Cadophora malorum, both are dark septate endophytes (DSEs). Some endophytes were found to possess antimicrobial properties that could be helpful for the host in evading the pathogens. These endophytes generally produced significant quantities of indole acetic acid (IAA) as well. However, thirteen of the endophytic taxa were found to cause corm rot in the host with different levels of severity under in vitro as well as in vivo conditions. This is the first report of community structure and biological properties of fungal endophytes associated with C. sativus, which may eventually help us to develop agro-technologies, based on plant-endophyte interactions for sustainable cultivation of saffron. The endophytes preserved ex situ, in this study, may also yield bioactive natural products for pharmacological and industrial applications.

Abstract
Domestic animals are susceptible to a large number of parasitic diseases, which lead to severe economic losses to livestock industry. So, it is necessary to control parasitic infections in these animals. Control of these helminths is undertaken mostly by anthelmintics, but because of their widespread use there is development of resistance across the globe. However, total dependence on a single method of control has proved to be non-sustainable and cost ineffective in the long term. A combination of treatment and management is necessary to control parasitism so that it will not cause further economic losses to producer as well as to livestock industry. To become practically and ecologically sustainable, parasitic control schemes need to be based on integrated parasite management.

Abstract
Aim: Gastrointestinal (GI) helminth parasitism is one of the major constraints for profitable sheep production. Due to variations in the prevalence of GI helminths from region to region, it becomes important to map out accurately the parasitic fauna of a particular region for development of suitable control measures. Materials and Methods: An extensive study of GI helminths was carried out in Budgam district of Kashmir Valley over a period of 1 year. A total of 1200 fresh ovine faecal samples from both sexes of young ones and adults were collected in sterilized plastic bags and examined by standard sedimentation and floatation techniques. Positive faecal samples (15-20%) in each season were examined by Stoll’s dilution method to determine the parasitic load. A total of 120 faecal samples (30 samples in each season) positive for strongyle eggs were subjected to coproculture using Petridish method and the third stage larvae were harvested to find out prevalence of different genera of strongyle worms. Results: The overall prevalence of GI helminths was found to be 77% with platyhelminths and nemathelminthes in 26.58 and 60.92% animals, respectively. The overall prevalence of mixed GI helminths was found to be 8.67%. Eggs of various helminths encountered in the present study were those of Fasciola spp. (3.58%), Dicrocoelium spp. (11.58%), paramphistomes (4.83%), Moniezia spp. (7.92%), strongyle worms including Nematodirus spp. (57.75%), Strongyloides spp. (1.67%), and Trichuris spp. (1.5%). On coprocultural examination Haemonchus spp. (55%) was found to be most predominant strongyle worm followed by Trichostrongylus spp. (17.5%), Ostertagia spp. (11.67%), Oesophagostomum spp. (9.17%), and Chabertia spp. (6.67%). On seasonal basis, highest prevalence of GI helminths was recorded in summer (83.00%) followed by spring (78.67%), winter (76.33%), and autumn (70.00%), the difference being statistically non-significant (p>0.05). The prevalence of platyhelminths (Fasciola spp., Dicrocoelium spp. and Moniezia spp.) was found to be non-significantly higher in winter, but paramphistomes showed the highest prevalence in the summer season. Nemathelminth infection was found highest in summer season and lowest during the winter season. Eggs per gram (EPG) ranged from 0 to 1800, and an average EPG count was found to be 454.35±27.85. EPG was found to be highest in summer (684.00±69.83) and lowest in winter (202.38±18.82). The overall prevalence of GI helminths was found more in adult sheep (83.00%) compared to young ones (53.11%), the difference being statistically significant (p<0.05). Similarly, the prevalence of helminths was found to be higher in females (78.32%) as compared to males (72.97%), the variation being statistically non-significant (p>0.05). Conclusion: Seasonal variation plays an important role in the prevalence of GI helminths in addition to age and sex of the animal.

Abstract
Background Crocus sativus stigmas form rich source of apocarotenoids like crocin, picrocrocin and saffranal which besides imparting color, flavour and aroma to saffron spice also have tremendous pharmacological properties. Inspite of their importance, the biosynthetic pathway of Crocus apocarotenoids is not fully elucidated. Moreover, the mechanism of their stigma specific accumulation remains unknown. Therefore, deep transcriptome sequencing of Crocus stigma and rest of the flower tissue was done to identify the genes and transcriptional regulators involved in the biosynthesis of these compounds. Results Transcriptome of stigma and rest of the flower tissue was sequenced using Illumina Genome Analyzer IIx platform which generated 64,604,402 flower and 51,350,714 stigma reads. Sequences were assembled de novo using trinity resulting in 64,438 transcripts which were classified into 32,204 unigenes comprising of 9853 clusters and 22,351 singletons. A comprehensive functional annotation and gene ontology (GO) analysis was carried out. 58.5 % of the transcripts showed similarity to sequences present in public databases while rest could be specific to Crocus. 5789 transcripts showed similarity to transcription factors representing 76 families out of which Myb family was most abundant. Many genes involved in carotenoid/apocarotenoid pathway were identified for the first time in this study which includes zeta-carotene isomerase and desaturase, carotenoid isomerase and lycopene epsilon-cyclase. GO analysis showed that the predominant classes in biological process category include metabolic process followed by cellular process and primary metabolic process. KEGG mapping analysis indicated that pathways involved in ribosome, carbon and starch and sucrose metabolism were highly represented. Differential expression analysis indicated that key carotenoid/apocarotenoid pathway genes including phytoene synthase, phytoene desaturase and carotenoid cleavage dioxygenase 2 are enriched in stigma thereby providing molecular proof for stigma to be the site of apocarotenoid biosynthesis. Conclusions This data would provide a rich source for understanding the carotenoid/apocarotenoid metabolism in Crocus. The database would also help in investigating many questions related to saffron biology including flower development.

Abstract
The present study explores the fungal endophytes from selected high value medicinal plants to check their activities at in-vitro and in-vivo level. The in-vitro cytotoxicity of selected endophytes revealed potent growth inhibition against human cancer cell lines of leukemia (THP-1), lung (A549), prostate (PC-3), colon (Caco-2), neuroblastoma (IMR-32) and breast (MCF-7) at a concentration of 100 µg/ml. Among them the endophytic strains I. e., IIIM2, IIIM3, IIIM7 and IIIM8 showed most significant growth inhibition against colon (Caco-2), prostate (PC-3), lung (A549) and leukemia (THP-1) cancer cell lines. At the in-vivo level maximum (58.95%) tumor growth inhibition was documented with the extract of IIIM2 against Ehrlich Ascites Carcinoma mouse modal. All the potent fungal endophytic strains were characterized using ITS 4 and ITS 5 region sequencing and phylogenetic analysis was ascertained among them. This paper confirms the 2 elite endophytic fungal strains, IIIM2 and IIIM8, have the potential to act as a source of new anticancer compounds.

Abstract
Endophytism is the phenomenon of mutualistic association of a plant with a microorganism wherein the microbe lives within the tissues of the plant without causing any symptoms of disease. In addition to being a treasured biological resource, endophytes play diverse indispensable functions in nature for plant growth, development, stress tolerance, and adaptation. Our understanding of endophytism and its ecological aspects are overtly limited, and we have only recently started to appreciate its essence. Endophytes may impact plant biology through the production of diverse chemical entities including, but not limited to, plant growth hormones and by modulating the gene expression of defense and other secondary metabolic pathways of the host. Studies have shown differential recruitment of endophytes in endophytic populations of plants growing in the same locations, indicating host specificity and that endophytes evolve in a coordinated fashion with the host plants. Endophytic technology can be employed for the efficient production of agricultural and economically important plants and plant products. The rational application of endophytes to manipulate the microbiota, intimately associated with plants, can help in enhancement of production of agricultural produce, increased production of key metabolites in medicinal and aromatic plants, as well as adaption to new bio-geographic regions through tolerance to various biotic and abiotic conditions. However, the potential of endophytic biology can be judiciously harnessed only when we obtain insight into the molecular mechanism of this unique mutualistic relationship. In this paper, we present a discussion on endophytes, endophytism, their significance, and diverse functions in nature as unraveled by the latest research to understand this universal natural phenomenon.
