Introduction to Bulked Segregant Analysis BSA (bulked segregant analysis) is a method for identifying genetic markers linked to a mutant phenotype. Geneticists can use this information to find genes that confer disease resistance or susceptibility. ...
Abstract A field experiment was conducted during the Kharif season of 2018-19 at Rice Research Station Bahawalnagar on the calcareous sandy loam soil to assess the effect of foliar application of boron on growth & yield components of rice varieties (Kissan & Punjab Basmati 2016).The foliar application of boron aqueous solution was used as treatments comprised of control, 0.5kg/ha, ...
A hydroponic experiment was conducted to investigate the perchlorate (ClO4‐) phytotoxicity in different rice varieties. Considerable variations were observed when 24 rice varieties were treated with ClO4‐. The shoot height, root length and biomass of most varieties were significantly reduced by ClO4‐. The roots were more sensitive than the shoots. Hierarchical clustering analysis demonstrated ...
In October 2013, one of the fiercest cyclones to hit the Bay of Bengal for many years made landfall on the low-lying delta coast of the Indian state of Odisha. With winds battering the coastline at more than 200 kilometres per hour, the structural damage from cyclone Phailin was intense. Thousands of straw, timber and bamboo homes were destroyed across the delta of the River Mahanadi, one of ...
Combining science with traditional knowledge, researchers turn to ancient rice as a source of climate resilience In May 2009, Cyclone Aila wreaked havoc in eastern India. Clocking in at speeds of over 120 kilometers per hour, Aila hit the Sundarbans, the largest continuous block of mangrove forest in the world, located in the Ganga-Brahmaputra tidal delta on the Bay of Bengal. The storm killed ...

It’s an approach meant, ultimately, to make it easier for scientists to design, test and build living parts and systems — even entire genomes. If genetic sequencing is about reading DNA, and genetic engineering as we know it is about copying, cutting and pasting it, synthetic biology is about writing and programming new DNA, with two main goals: ...

The effects of insect‐resistant genetically engineered rice producing Cry1C protein derived from Bacillus thuringiensis (Bt) on Chrysoperla sinica Tjeder (Neuroptera: Chrysopidae) were assessed in laboratory bioassays. ...
Because of the prevalence of algae in rice paddy fields, they will be exposed to Bacillus thurigiensis (Bt) proteins released from Bt protein‐expressing genetically engineered rice. To assess the effects of leachates extracted from Cry1Ca‐expressing transgenic rice (T1C‐19) straw on the microalga Chlorella pyrenoidosa, we ...
A July study revealed the first evidence directly linking consumption of rice containing arsenic to genetic damage in humans. Such findings are especially alarming because rice is a major part of the diet in certain communities, such as those with an Asian heritage, and because rice is a staple for infants and young children, ...
With a reliable and custom summary of environmental regulations that addresses ONLY THOSE REGULATIONS THAT HAVE THE POTENTIAL TO IMPACT YOU AND YOUR BUSINESS, you can address issues upfront and aggressively, resulting in more time available to run your business effectively and without environmental compliance issues. Tracking Environmental Regulations Un often be a backburner chore for ...
Intrusion of saline water and soil salinity is a major threat of climate change to agriculture. Rice is the most important crop affected by salinity in the coastal area of Bangladesh. The objective of this paper is to develop tools for ex ante cost-benefit assessment, with an integration of knowledge of farmers, industry experts and scientists to develop new salinity and drought resistant (SDR) ...
A major challenge in rice (Oryza sativa L.) production is to achieve the dual goal of increasing food production and saving water. This study aimed to investigate if alternate wetting and drying regimes could improve root and shoot growth and consequently increase grain yield and water use efficiency (WUE). Two rice varieties were field-grown at Yangzhou, China in 2005 and 2006. Three irrigation ...
Improving the cooking and eating quality of grain has always been an important consideration in most rice (Oryza sativa L.) breeding programs. In this study, an established rice doubled-haploid (DH) population consisting of 219 lines from anther culture of the F1 of indica variety PSB Rc10 and japonica variety Nipponbare was used to identify the quantitative ...
In Brazil, rice (Oryza sativa L.) varieties adapted to different ecological regions are available on the market. However, these varieties exhibit highly similar morphologies, which makes their identification difficult. In this study we identified microsatellites in and around genes that are useful for the identification of the main rice varieties cultivated in Brazil. Thirteen microsatellites ...
In an attempt to improve salt tolerance of rice, we introduced katE, a catalase gene of Escherichia coli, into japonica rice cultivar, Nipponbare. ...
The tested material (six genotypes) was generated by crossing fine varieties of rice viz. Basmati-370 and Basmati-385 with three coarse varieties of rice viz. NIAB-IRRI-9, Jhona-349 and NIAB-Rice-1. The mutants (seven mutants) were derived by gamma irradiation of rice varieties, Basmati-370 and Basmati-385. ...
Drought-Tolerant (DT) rice technology is a potential tool to improve productivity in regions with insufficient or variable water supply. The impacts of DT rice adoption are analysed using the Arkansas Global Rice Model to demonstrate that DT rice would benefit the early investors in developing and adopting DT varieties. ...
