The study aimed to determine farmers' knowledge, attitudes, and practices (KAPs) of hybrid rice adoption, and the causal relationship between them in Bangladesh. Using a stratified random sampling technique, 244 cross-sectional surveys were done from the Sherpur district of Bangladesh. The descriptive statistics, two-round Delphi method, and partial least squares structural equation modeling (PLS-SEM) were used to estimate latent variables and identify the causal relationship between KAPs. The results revealed that farmers' knowledge and attitudes were directly and significantly associated with the adoption of hybrid rice. This implies that farmers who are well informed about the usage of hybrid rice and are likely to embrace it and raise their revenue, can be influenced by knowledge. The study found a significant positive role for knowledge about hybrid rice, attitudes, and practices in adopting hybrid rice. This study provides a primary understanding of the relationship between psychological factors and the adoption of hybrid rice technology to increase rice farm productivity. The findings suggest that policymakers, researchers and development agencies should focus on farmers' psychological factors in improving the adoption of hybrid rice in Bangladesh.","PeriodicalId":501763,"journal":{"name":"GM Crops & Food","volume":" ","pages":"327-341"},"PeriodicalIF":3.9,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9683048/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40700350","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}

As one of the abiotic stress hazards, low temperatures seriously affect the yield of maize. However, the genetic basis of low-temperature adaptation in maize is still poorly understood. In this study, maize S-adenosylmethionine decarboxylase (SAMDC) was localized to the nucleus. We used Agrobacterium-mediated transformation technology to introduce the SAMDC gene into an excellent maize inbred line variety GSH9901 and produced a cold-tolerant transgenic maize line. After three years of single-field experiments, the contents of polyamines (PAs), proline (Pro), malondialdehyde (MDA), antioxidant enzymes and ascorbate peroxidases (APXs) in the leaves of the transgenic maize plants overexpressing the SAMDC gene significantly increased, and the expression of elevated CBF and cold-responsive genes effectively increased. The agronomic traits of the maize overexpressing the SAMDC gene changed, and the yield traits significantly improved. However, no significant changes were found in plant height, ear length, and shaft thickness. Therefore, SAMDC enzymes can effectively improve the cold tolerance of maize.","PeriodicalId":501763,"journal":{"name":"GM Crops & Food","volume":" ","pages":"131-141"},"PeriodicalIF":3.9,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9291676/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40608396","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}

Conventional mango breeding practices are unable to withstand the demand for improved varieties as it is time consuming and requires heavy investment. However, problems associated with traditional plant breeding can be curtailed through genetic transformation. Nevertheless, major limitation of transgenic development has been its recalcitrant nature toward tissue culture practices involving latent microbial infection, phenol exudation, etc. This opens wide scope for tissue culture-independent in planta transformation approaches These strategies have proved to be easy to execute and cost effective in producing large number of transformants. One such apical meristem targeted in planta approach was successfully exploited to demonstrate its utility in transforming a tree species. Mango variety Amrapali was transformed with two visual marker gene vectors GFP::hptII in pCAMBIA1302 and GUS::nptII in pCAMBIA2301 individually, to demonstrate its amenability. Preliminary confirmations identified 65.0% of GFP and 57.14% of GUS plants to be transformed. Further, molecular characterization of these primary transformants demonstrated transgene integration at genomic and transcript level in some of the plants. This established protocol holds good for functional gene validation and knock in/out studies and aid in mango improvement programs.","PeriodicalId":501763,"journal":{"name":"GM Crops & Food","volume":" ","pages":"342-354"},"PeriodicalIF":3.9,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9704399/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40703902","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}
