The plant growing in soilless culture in a closed system, vertical farming, and protected cultivation under controlled climatic factors has immense potential for crop improvement in different aspects of phytoremediation, stress tolerance and bio fortification. The water-based culture and substrate-based culture induce classified stress tolerance in crops such as disease stress, water stress, salt stress under controlled climatic factors and can also be utilized to develop bio fortified crops. The scope and possibilities of crop improvement through water-based culture and substrate-based culture with respect to phytoremediation, stress tolerance, bio fortification, mechanisms of crop improvement and the challenges in crop improvement through soilless culture are reviewed in this paper. The soilless culture has enormous tools to combat problem of crop improvement and call for soilless green revolution.

Negative correlation was noticed for yield under stress (YS) with tolerance index (TOL), yield reduction ratio (Yr) and stress susceptibility index (SSI).

Understanding the biological function of fern genes and their potential uses for agriculture, environment and health has been hampered by the lack of high-quality genome sequence of fern. The last five years have seen the assembly of reference fern genomes of <em>Salvinia cucullata</em> (0.26 Gb, n = 9), <em>Azolla filiculoides</em> (0.75 Gb, n = 22), <em>Adiantum capillus-veneris</em> (4.83 Gb, n = 30), <em>Alsophila spinulosa</em> (6.27 Gb, n = 69) and <em>Ceratopteris richardii</em> (7.46 Gb, n = 39). These high-quality genome sequences will make significant contribution to the better understanding of evolution, ecology, functional genomics, and the diverse applications of ferns. Here, I review the physiological and some aspects of limited molecular mechanisms of abiotic (mainly heavy metal, drought, and shade) and biotic (pests and pathogens) tolerance in different fern species. The potential use of the fern genome toward crop abiotic and biotic stress tolerance is suggested. Thus, deciphering the genetic diversity and novel functional genes of ferns will provide tremendous boost to the knowledge advancement and the biotechnological applications of unique fern genes and proteins for sustainable agricultural production and environmental protection.</p></div>","PeriodicalId":100341,"journal":{"name":"Crop Design","volume":"1 2","pages":"Article 100013"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772899422000131/pdfft?md5=6d7399948e878d9a66113a89971b3ed3&pid=1-s2.0-S2772899422000131-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79213701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lack of systematic researches on efficient propagation of pathogenic <em>F. fujikuroi</em>, artificial inoculation technology and the pathogenic conditions presents a critical technological gap that has severely hampered research on rice resistance to bakanae disease. This study first explored the sporulation conditions of <em>F. fujikuroi</em> in mung bean liquid medium, and determined that <em>F. fujikuroi</em> cultured in 40 g/L mung bean liquid medium for 2–6 days could efficiently produce pathogenic spores in large quantity. On this basis, we further establish an artificial inoculation system to induce bakanae disease. The main steps and parameters include: Soak rice seeds in a <em>F. fujikuroi</em> spore solution with a concentration of 1 × 10<sup>6</sup> conidia/mL for 2 days; let imbibed seeds germinate, and choose germinating seeds with buds of a grain length and cultivate them on half strength MS medium (1/2 MS, pH 5.8–6.8) for about a week. The characteristic bakanae symptoms of excessively elongated seedlings could thus be induced. Furthermore, we found that the bakanae disease symptoms became more profound when a small amount of PDA (0.5%) was added to 1/2 MS medium. Hence our study established a technical system for the artificial induction of bakanae disease involving the use of mung bean medium for rapid propagation of <em>F. fujikuroi</em> spores, seed inoculation and cultivation of seedlings in 1/2 MS medium added with 0.5% PDA. This system will enable quick assessment of bakanae disease resistance and thus will be useful for rice breeding.</p></div>","PeriodicalId":100341,"journal":{"name":"Crop Design","volume":"1 2","pages":"Article 100016"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772899422000167/pdfft?md5=fc953add0dd0882be1b9ae60d48e36b1&pid=1-s2.0-S2772899422000167-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84774338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A clean transgenic plant (CTP) contains only the defined transgene, whilst a clean edited plant (CEP) is transgene-free. Currently, it is difficult and time-consuming to identify and locate transgenes within plant genomes due to the complex nature of transfer DNA (T-DNA) or plasmid backbone integration, which has led to a major obstacle in mass scale production of clean transgenic/edited plants (CTREPs). Here we have built a web-based portal, CTREP-finder, for fast detection, characterization and visualization of foreign DNA fragments in plants, based on next-generation whole genome sequencing data. We invented a novel bioinformatics strategy to handle three scenarios of transgene integration and successfully identified CTREPs by testing 132 samples. Furthermore, we compared the CTREP-finder with three public programs, FED, transgeneR and TDNAscan, and it showed that the CTREP-finder outperforms those programs particularly on the localization of transgene integration. The use of CTREP-finder needs little requirement for bioinformatics expertise. Therefore, it is a user-friendly web-based portal that could be used by plant breeders and regulatory agencies for the rapid selection/detection of CTREPs for crop breeding and production.</p></div>","PeriodicalId":100341,"journal":{"name":"Crop Design","volume":"1 1","pages":"Article 100003"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772899422000039/pdfft?md5=0c122e3eeb7bfa7566d2a94bf9d90647&pid=1-s2.0-S2772899422000039-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78199492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
