Germination timing influences plant fitness, and its sensitivity to temperature may cause it to change as climate shifts. These changes are likely to be complex because temperatures that occur during seed maturation and temperatures that occur post-dispersal interact to define germination timing. We used the model organism Arabidopsis thaliana to determine how flowering time (which defines seed...

The ABCC multidrug resistance associated proteins (ABCC-MRP), a subclass of ABC transporters are involved in multiple physiological processes that include cellular homeostasis, metal detoxification, and transport of glutathione-conjugates. Although they are well-studied in humans, yeast, and Arabidopsis, limited efforts have been made to address their possible role in crop like wheat. In the pr...

The development of alien addition lines is important for transferring useful genes from exotic species into common wheat. A hybrid of common wheat cv. 7182 (2n = 6x = 42, AABBDD) and Psathyrostachys huashanica Keng (2n = 2x = 14, NsNs) via embryo culture produced the novel intergeneric disomic addition line 59-11. The seed morphology of 59-11 resembled the parent 7182 and it exhibited extreme a...

Introduction Stand establishment is the first step in producing a good wheat crop, and most producers intend to obtain a uniform stand of wheat. However, intentions are not always the same as reality when it comes to wheat establishment. A study conducted in the early 1990s by the OSU Small Grains Extension Program compared producer perception of wheat seeding accuracy with actual field measure...

In order to study the effects of wild mustard competition and different levels of nitrogen on effective traits of wheat yield, this research was conducted in Ahvaz, south west of Iran. The study was consisted of a split plot experiment, on the basis of Randomized Complete Blocks Design with three replications. Different levels of nitrogen (90, 150 and 210 kgN.ha-1) were assigned in the main plo...

Targeted mutagenesis using programmable DNA endonucleases has broad applications for studying gene function in planta and developing approaches to improve crop yields. Recently, a genetic method that eliminates the need to emasculate the female inbred during hybrid seed production, referred to as Seed Production Technology, has been described. The foundation of this genetic system relied on cla...

There is a general belief that the quality of tomatoes ripened on vine is better than tomatoes ripened off the vine, influencing among other parameters, the price of this commodity. We compared the quality of hydroponic tomatoes ripened on and off vine by chemical, physical, and sensory evaluation to find what attributes are affected and to what extent. Lycopene, beta-carotene, total and solubl...
