silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...

in this study, genetic diversity of 20 wheat genotypes was evaluated using 126 simple sequence repeats (ssr) alleles, covering all three wheat genomes. a total of 1557 allelic variants were detected for 126 ssr loci. the number of alleles per locus ranged from 4 to 19 and the allelic polymorphism information content (pic) varied from 0.66 (xgwm429) to 0.94 (xgwm212 and xgwm515). the high­est po...

12W932-349 is a soft red winter wheat (Triticum aestivum L.) cultivar registered for Ontario, Canada. It has high grain yield with good pastry quality and moderately resistant to Fusarium head blight. well adapted the growing areas of Ontario.

Vacuoles isolated from pea (Pisum sativum), and wheat (Triticum aestivum) leaf protoplasts contained considerable activities of electrophoretically highly mobile exoamylases. Vacuoles from spinach (Spinacia oleracea) leaf and photoautotrophic Chenopodium rubrum suspension culture cell protoplasts were devoid of amylolytic activity. Endoamylase activity was in all cases associated primarily with...

Ethylene evolution from etiolated barley (Hordeum vulgare), wheat (Triticum aestivum), and rye (Secale cereale) seedlings during coleoptile growth followed a rhythmic pattern, with a period of about 16 h for barley and wheat and 12 h for rye seedlings. Leaf emergence disturbed the established rhythm of ethylene evolution.

Kernel texture (‘hardness’) is an important trait that determines end-use quality of wheat (Triticum aestivum L. and Triticum turgidum ssp. durum [Desf.] Husn.). Variation in texture is associated with the presence/absence or sequence polymorphism of two proteins, puroindoline a and puroindoline b. This work describes the flanking and coding region sequences of puroindoline genes from 25 access...

Etiochloroplasts isolated from greening wheat (Triticum aestivum L. cv Norin 61) seedlings synthesized a membrane polypeptide of 15 kilodaltons. One-dimensional peptide mapping with Staphylococcus aureus V8 protease revealed that the 15 kilodaltons polypeptide is the subunit 5 of photosystem I reaction center complex.

From leaves of Triticum aestivum a new O-glycosylflavone has been isolated together with chlorogenic acid and its 3'-methyl ether and 6 C-glycosylflavones. The structure of the new flavonoid was determined by 1D and 2D NMR techniques and other spectral evidence as 5,7-dihydroxy-3',4',5'-trimethoxyflavone-7-O-beta-rutinoside.

In vitro assays using recombinant enzymes enabled three cDNAs encoding ent-copalyl diphosphate synthases to be identified in wheat (Triticum aestivum): TaCPS1, TaCPS2, and TaCPS3. The phylogenetic tree and expression analyses suggest that TaCPS3 is responsible for gibberellin biosynthesis, while TaCPS1 and TaCPS2 are possible functional homologs of diterpene cyclase genes OsCPS2 and OsCPS4 invo...
