This document contains a list of 10 Islamic websites providing religious content and resources. The websites cover topics such as the Quran, Hadith, Islamic teachings and practices, and tools for finding mosques and prayer times. The document also mentions including video subtitles and Huseeyin Abi's farewell sermon on one of the listed sites.
The International Wheat Genome Sequencing Consortium (IWGSC) announced on January 7, 2016 in Bethesda, Maryland, USA the production of a whole genome assembly of bread wheat, the most widely grown cereal in the world, significantly accelerating global research into crop improvement.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like depression and anxiety.

1. The ABC model proposes that floral organ identity is specified by three classes of organ-identity genes (A, B, and C) that function in overlapping domains within a flower to determine the four whorls.
2. Class A genes like AP1 specify sepals and petals, class B genes like AP3 and PI specify petals and stamens, and the class C gene AG specifies stamens and carpels.
3. Studies on floral organ development mutants and gene expression patterns provided strong support for the ABC model, but it was later expanded to include class E genes like SEP that work together with the ABC genes to specify organ identity in each whorl.
This document discusses applying genomic selection to a rice breeding program using a synthetic population and recurrent selection. Key points:
- Genomic selection was tested on 343 rice families from a synthetic population with 10 cycles of recombination to estimate its feasibility. Various regression models were evaluated.
- Accuracy of genomic selection was found to depend on trait architecture, heritability, and marker selection. Flowering date saw improved accuracy when markers were selected based on linkage disequilibrium.
- The results indicate genomic selection is feasible for this rice breeding program, though further data across sites and years is still needed to develop stronger prediction models. Genomic selection could help increase selection intensity and reduce time in the recurrent selection scheme.
Plant dormancy is a survival mechanism where growth is temporarily suspended. There are two main types - seed dormancy and bud dormancy. Seed dormancy prevents germination during unsuitable conditions and allows for dispersal. It can be caused by hard seed coats or environmental factors. Bud dormancy suspends growth in perennial plants during winter. Hormones like ABA promote dormancy while gibberellins and cytokinins break dormancy. Temperature also influences seed germination and dormancy breaking. Dormancy ensures plant survival during unfavorable periods and promotes species survival.
This document discusses single nucleotide polymorphisms (SNPs). It defines SNPs as variations in DNA sequences that occur when a single nucleotide differs between members of a species. SNPs are the most common type of genetic variation. The document outlines the characteristics of SNPs, how they are used as genetic markers, and various methods for SNP genotyping, including direct sequencing, TaqMan assays, and microchips. It also discusses the advantages and applications of SNPs in areas like gene discovery, disease risk profiling, and genetic variation studies.

Overview on arabidopsis and rice genomeGopal Singh
This document summarizes the sequencing of the Arabidopsis and rice genomes. It describes that Arabidopsis was the first plant and third multicellular organism to have its genome sequenced, which was completed in 2000 through an international collaboration. The rice genome sequencing project began in 1997 and was completed in 2005, providing a 389Mb sequence with 95% accuracy. Both projects used BAC and PAC libraries to sequence the genomes. The Arabidopsis genome is 115Mb across 5 chromosomes, while the rice genome is larger at 400-430Mb across 12 chromosomes.
