Six-rowed barley originated from a mutation in a homeodomain-leucine zipper I-class homeobox gene.
Increased seed production has been a common goal during the domestication of cereal crops, and early cultivators of barley (Hordeum vulgare ssp. vulgare) selected a phenotype with a six-rowed spike that stably produced three times the usual grain number. This improved yield established barley as a founder crop for the Near Eastern Neolithic civilization. The barley spike has one central and two...
متن کاملLysine Catabolism in Barley (Hordeum vulgare L.).
Lysine catabolism in seedlings of barley (Hordeum vulgare L. var. Emir) was studied by direct injection of the following tracers into the endosperm of the seedlings: aspartic acid-3-(14)C, 2-aminoadipic acid-1-(14)C, saccharopine-(14)C, 2,6-diaminopimelic acid-1-(7)-(14)C, and lysine-1-(14)C. Labeled saccharopine was formed only after the administration of either labeled 2,6-diaminopimelic acid...
متن کاملشناسایی نشانگرهای AFLP پیوسته به ژن کنترل کننده تعداد ردیف بذر در جو
Formation of the two- and six-rowed types in barley is predominantly controlled by alleles at a single locus (vrs1) which is located in long arm of chromosome 2H. This gene is a key character on the study of barley domestication and yield. Near-isogenic lines (NILs) of barley were produced from crosses between Kanto Nakate Gold (tow-rowed) and Azumamugi (six-rowed). The selected lines were used...

متن کاملHigh Resolution Analysis of Meiotic Chromosome Structure and Behaviour in Barley (Hordeum vulgare L.)
Reciprocal crossing over and independent assortment of chromosomes during meiosis generate most of the genetic variation in sexually reproducing organisms. In barley, crossovers are confined primarily to distal regions of the chromosomes, which means that a substantial proportion of the genes of this crop rarely, if ever, engage in recombination events. There is potentially much to be gained by...
