But the poor nitrogen use efficiency (NUE, about < 40%) causes many economic and environmental challenges. The microbial oxidative process of converting ammonia to nitrite to nitrate (nitrification) is the rate-limiting step in the N loss. The century-old, conventional theory of nitrification with the involvement of two functionally different bacterial groups as ammonia-oxidizing bacteria and nitrite-oxidizing bacteria has been upturned by the recent discoveries of archaeal members involved in ammonia oxidation (Ammonia-oxidizing archaea, AOA), anaerobic ammonia-oxidizing bacteria (Anammox bacteria) and complete ammonia oxidizing bacteria (Comammox bacteria) in the last two decades, largely due to the advances in molecular and metagenomic methods introduced to study the microbial ecology. What is interesting to know is that nitrate-transporters of host plants, as in rice, are involved in the assembly of the microbiome associated with roots. Besides, rice plants produce the biological nitrification inhibiting (BNI) compounds released through root exudates. Involvement of diverse microbiome members and the plant genome through nitrate transporters on the rice rhizosphere microbiome assembly necessitates the reappraisal of the nitrogen fertilization management options. This paper also highlights the need for gathering new knowledge on the plant-microbe interactions, from the genome to metabolite levels, and conserving these resources for sustainable rice cultivation.","PeriodicalId":13295,"journal":{"name":"Indian Journal of Plant Genetic Resources","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72741580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among 40 non-carnivores livestock species domesticated by human being, till date, only cattle, sheep, goat, pig and chicken are highly prevalent and known as ‘Big five’. Other species like buffalo, dromedaries and Bactrian camel, llama, alpaca, yak, and mithun are region specific. At present, about one-fifth of the global food is of animal origin in the world. A vast genetic diversity of AnGR has been generated during hundreds of years through culmination of various evolutionary forces, including intensive selection and preferred mating by human for various utilization purposes. Initial domestication modulated the wild ancestors to adapt to human habitation and making themselves more useful for the human being. Migration of animals by humans across the continents further disseminated the germplasm, initiating the diversification of the farm animals across the globe. However, artificial selection for different needs and likings by the human is the chief element for development of large-scale genetic diversity, in form of distinct breeds and populations. These breeds as well as specialized populations have been evolved for a specific need or utilization pattern like milk, draft, meat, fibre, carting, riding etc. Today, the world possesses more than eight thousand livestock and poultry breeds, evolved from only few founder populations and catering various needs of human society around the world. As per Global data bank on Animal Genetic Resources of FAO, a total of 8774 breeds of 38 species were reported, worldwide (data from 182 countries) in 2014. Among these, 7718 are local breeds (in one country) and 510 are regional transboundary breeds (in one region) and 546 are international transboundary breeds (in more than one region).","PeriodicalId":13295,"journal":{"name":"Indian Journal of Plant Genetic Resources","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88572498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ICAR-National Bureau of Plant Genetic Resources (ICAR-NBPGR) is authorized to issue import permit and undertake quarantine of plant germplasm including transgenics and for issue of Phytosanitary Certificate for material under export. Adopting a systematic workable strategy, using a combination of conventional and modern techniques, over the past forty-five years, a total of 78 exotic pests including fungi (6), viruses (19), insects/ mites (26), nematodes (9) and weeds (18) of great quarantine significance to India have been intercepted. All efforts are made to salvage the infested/ infected materials; however, if the material is unsalvageable, it was incinerated. The interceptions made signify the potential dangers in import of planting material if proper quarantine measures had not been followed. ICAR-NBPGR, also makes concerted efforts to develop and customize the modern detection and eco-friendly salvaging techniques to minimize the risk of escape in quarantine processing. Scientifically sound and transparent risk analysis prior to import is an important tool, so that, our agricultural production is not jeopardized. The Indian phytosanitary regulations provide a fragmented legislative system which needs to be harmonized and integrated to holistically deal with national biosecurity while complying with international norms. Also, there is a need to support research, training, capacity-building, networking and information sharing activities at both national and regional levels.","PeriodicalId":13295,"journal":{"name":"Indian Journal of Plant Genetic Resources","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89562270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
