Seed coat color in soybean is determined by four alleles of the classically defined / (inhibitor) locus that controls the presence or absence as well as the spatial distribution of anthocyanin pigments in the seed coat. By analyzing spontaneous mutations of the / locus, we demonstrated that the / locus is a region of chalcone synthase (CHS) gene duplications. Paradoxically, deletions of CHS gen...

Abstract: IAC 2051 is a common bean (Phaseolus vulgaris L.) cultivar with carioca-type seed coat, mean 1000 weight of 300g, indeterminate semi-upright type II growth habit, slow post-harvest coat darkening, resistance to Fusarium wilt, bacterial blight, and three races anthracnose, yield 2729 kg ha-1.

Seed treatments are frequently applied for the management of early-season pests, including seed-borne pathogens. However, to be effective against internal pathogens, active ingredient must able penetrate seed coat. Tomato seeds were focus this study, and objectives (1) evaluate three coumarin fluorescent tracers in terms uptake (2) quantify coat permeability relation lipophilicity better elucid...

to study seed dormancy and the after-ripening period in barley genotypes (57 dutch genotypes and two iranian cultivars (gorgan and valfair)), an experiment of randomized complete block design (two replications) was conducted at the research farm of collage of agriculture and natural resources, university of tehran in 2004-2005. in the growing stage of zgs92, panicle was collected. the percentag...

To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatment with GA3, KNO3, or thiourea. Treatments with 7,500 ppm KNO3 after 120 days of stratification were more effective, yielding 64.54% germination of seeds with coat. In seeds without coat, 500 ppm G...

seed hardiness in annual medics plays an important role in soil seed bank reserve to ensure ley farming system sustainability. to study the level of seed hardiness in annual medic (medicago scuttelata var.rabinson) at different fertilizing treatments and growing conditions (irrigated and dry farming system), an experiment was conducted at two research stations (sararod, research institute and s...

UDP glycosyltransferases (UGTs) play an indispensable role in regulating signaling pathways and intracellular homeostasis plants by catalyzing the glycosylation of metabolites. To date, molecular characteristics potential biological functions UGT gene family pomegranate (Punica granatum L.) remain elusive. In this study, a total 120 PgUGT genes were identified genome. Phylogenetic analysis reve...

A comparative study of proteome and transcriptome changes during Medicago truncatula (cultivar Jemalong) seed development has been carried out. Transcript and protein profiles were parallel across the time course for 50% of the comparisons made, but divergent patterns were also observed, indicative of post-transcriptional events. These data, combined with the analysis of transcript and protein ...

Yellow seeds are a favorable trait for Brassica crops breeding due to better quality than their black-seeded counterparts. Here, we compared the Brassica napus seed coat transcriptomes between yellow- and brown-seeded near-isogenic lines (Y-NIL and B-NIL) that were developed from the resynthesized yellow-seeded line No. 2127-17. A total of 4,974 differentially expressed genes (DEG) were identif...

A computer vision system was used to evaluate seed coat and cotyledon cracks in soybeans. White light in the front-lighting mode with a black background for the soybeans was the best condition for acquiring video images of soybeans suitable for subsequent processing. Image processing algorithms were developed using the software supplied with the vision system computer. Crack detection was most ...
