Abstract Reduced height ( Rht ) genes are widely used in modern wheat breeding although some confer higher susceptibility to Fusarium head blight (FHB) caused by F. graminearum and other species. Our objective was test whether the recently identified Rht24b dwarfing allele has a neutral effect on FHB response as reported previously from single mapping population when unrelated winter cultivars ...
The extensive use of two alleles (Rht-B1b and Rht-D1b) at the Rht-1 locus in wheat allowed dramatic increases in yields, triggering the so-called "Green Revolution." Here, we found that a new natural allelic variation (Rht-B1i) containing a single missense SNP (A614G) in the coding region significantly increased plant height against the genetic background of both Rht-D1a (11.68%) and Rht-D1b (7...
Grain hardness is one of the most important quality characteristics of wheat (Triticum aestivum L.). It is a significant property of wheat grains and relates to milling quality and end product quality. Grain hardness is caused by the presence of puroindoline genes (Pina and Pinb). A collection of 25 genotypes of wheat with unusual grain colour (blue aleurone, purple and white pericarp, yellow e...
Dopamine is a key neuromodulatory transmitter in the brain. It acts through dopamine receptors to affect changes in neural activity, gene expression, and behavior. In songbirds, dopamine is released into the striatal song nucleus Area X, and the levels depend on social contexts of undirected and directed singing. This differential release is associated with differential expression of activity-d...
In soybean, an environmentally stable male sterility system is vital for making hybrid seed production commercially viable. Eleven male-sterile, female-fertile mutants (ms1, ms2, ms3, ms4, ms5, ms6, ms7, ms8, ms9, msMOS, and msp) have been identified in soybean. Of these, eight (ms2, ms3, ms5, ms7, ms8, ms9, msMOS, and msp) have been mapped to soybean chromosomes. The objectives of this study w...
Mantle cell lymphoma (MCL) has a rather poor prognosis and currently no truly effective therapy. Gene translocation-mediated constitutive expression of Cyclin D1 seems to play the key role in the pathogenesis of MCL. Here we report that whereas three out of four MCL cell lines expressed the recently identified, highly oncogenic Cyclin D1b isoform, in addition to the canonical Cyclin D1a , eight...
BACKGROUND The evolution and correlation between the aortic neck and distally located iliac necks after endovascular treatment of abdominal aortic aneurysms (AAAs) was studied. METHODS Of 179 patients who had undergone AAA repair between 2003 and 2007, 61 received the same radiologic follow-up and were included in this retrospective study. Data for 61 aortic necks and 115 iliac arteries were ...
سختی دانه یکی از مهم ترین ویژگی های کیفی گندم نان است که نقش اساسی در قدرت جذب آب توسط آرد و اندازه ذرات آن دارد. سختی دانه گندم تحت کنترل مکان ژنی (ha) روی کروموزوم 5d می باشد. در این تحقیق با آزمون مکانیکی بوسیله دستگاه کشش و فشار (ct) و آزمون مکانیکی نوری (nir) بوسیله دستگاه اینفراماتیک سختی ارقام با منشا های متفاوت مورد بررسی قرار گرفت و تنوع آللی ژن های پیوروایندولین، آلل هایpina-d1b،pina-...
