![]() ![]() cristatum alien chromosomes into common wheat depends on cytological genetic technology and molecular markers to track the alien chromosome fragment. cristatum have been conducted to transfer desirable traits into common wheat 6, 8, 10, 11, 12, 13, 14, 15, 16. cristatum, wide crosses between common wheat and A. cristatum carries many useful traits, including resistance to barley yellow dwarf, wheat streak mosaic virus 5, leaf rust 6, and powdery mildew 7 as well as large spike phenotype 8, making it a powerful genetic reservoir for the improvement of wheat 6, 9.ĭue to the abundance of diversified genetic resources of A. In addition to its resistance to drought and cold and its moderate tolerance to salinity 2, 3, 4, A. In the tribe Triticeae, Agropyron cristatum is a wild relative of wheat and an elite gene donor for wheat improvement. Wild relatives of crops contain broad genetic diversity and serve as gene donors to crops 1. Altogether, this study provided a universal method of large-scale molecular marker development to monitor wild relative chromatin in wheat. These markers were successfully applied in the tracking of alien A. An application case of all EST-STS markers was validated on the A. ![]() cristatum genome, and the marker distribution density was approximately 1.28 cM. These markers covered more than 98% of the A. A total of 4956 randomly selected polymorphic EST-STS markers were further tested in eight wheat variety backgrounds, and 3070 markers displaying stable and polymorphic amplification were validated. cristatum P genome in the single-receipt wheat background. As a result, 6063 polymorphic EST-STS markers were specific for the A. cristatum expressed sequence tag-sequence-tagged site (EST-STS) markers for PCR amplification and experimental screening. cristatum unigenes with the Chinese Spring reference genome sequences, we designed 9602 A. Here, we reported a resource of large-scale molecular markers for tracking alien introgressions in wheat based on transcriptome sequences. cristatum chromatin introgressions in wheat. However, very few markers can be used to monitor A. Will we be interviewing ourselves this year? Who knows! Either way, we look forward to the hunt and hope to see many of you out and about as we work to complete the task list.Agropyron cristatum is a wild grass of the tribe Triticeae and serves as a gene donor for wheat improvement. Both of our teams have been runners-up for many years in a row and each year we’ve interviewed the winning team ( 2014, 2015, 2016). Myself and Emily Rose are representing Team Subtext, while our new editor Khai is from Team Kale of the Lord. The Geekiary has two teams on staff this year. Still not convinced this is for you? Check out my team’s video of some of our best items from the past 5 years: We’ve also had a huge kindness impact, if you’re into that sort of thing. If you’re new to the hunt, the testimonials may also be of interest to you. Gishwhes 2017 will take place August 5th-12th 2017 and has a long list of commandments and FAQ‘s that both new and old players may find enlightening. And apparently space themed too! We get an additional theme on top of the color, it seems. The winning trip is to Hawaii and the color theme for the year is purple. Gishwhes 2017 is unique as this year’s mascot is the non-binary Porcupanda. Each year features a new mascott, color scheme, and trip destination. Thousands of members participate in groups of 15 aiming for the top prize: a trip with their team mates and scavenger hunt host Misha Collins. Get your teams together and let’s compete and have some fun!įor those that aren’t aware, Gishwhes (The Greatest International Scavenger Hunt the World Has Ever Seen) is an international scavenger hunt that combines art, stunts, performance, charitable acts, and other tasks for a week long photo and video competition. Gishwhes 2017 registration is officially open. ![]()
