With the proliferation of recommendation functions (RF) on e-Commerce websites, there is growing confusion about how various RF types affect consumers’ beliefs and behavior. Despite the importance of understanding the differential effects of RF types, research focusing on the comparison between provider-generated recommendations (PGRs) and user-generated recommendations (UGRs) has received litt...
Many plant growth regulators (PGRs) are known to alleviate the negative effects of drought stress in plants. However, limited research has been conducted to investigate the potential benefits of exogenous application of PGRs in wheat plants grown under drought stress. In the present study, effects of salicylic acid (SA) and chlormequat chloride (CCC) on drought-stress induced changes in morpho-...
The PE_PGRS33 protein is a member of the PE family, which encompasses the PE and the PE_PGRS subfamilies. Among PE_PGRS's, this protein is one of the most studied antigens and its immunomodulatory properties are influence by both PE and PGRS domains. However, the contribution of these domains to the host immune recognition of the PE_PGRS33 protein and their potential role in latent tuberculosis...
Plant growth regulators (PGRs), which are widely used in agriculture, have various effects on different morphological and physiological characteristics of wheat cultivars. To examine the effect of two PGRs [cycocel (CCC) and salicylic acid (SA)] on some morphological and physiological properties of bread (Roshan) and durum (Yavarous) wheat cultivars under different irrigation regimes [normal (a...
Intensified salinization of water and soil resources has promoted interest for research and approaches of improving crop yield under saline conditions. Reviewing the literature showed that the records on understanding of different aspects of salt stress and enhanced salinity tolerance in the world goes back to more than a century. Different approaches have been suggested to increase crop yield ...
Plant growth regulators (PGRs) are used to prevent reduction in wheat grain yield under limited moisture conditions. The effect of 3 PGRs including cycocel, salicylic acid and brassinoestroeid on yield and yield components of four wheat cultivars (Chamran, Shiroudi, Pishtaz and Sirvan) under well watered and water stress (withheld irrigation after flowering) was examined. The experiment was ca...
Geophytes are a very important group among ornamental plants, for which more and plant growth regulators (PGRs) being used to improve the quality, flowering intensity, vase life of flowers leaves. PGRs constitute large naturally occurring or synthetically produced organic chemical compounds. There many factors that influence efficiency PGRs, method their application plays key role in determinin...
High-temperature stress degrades the grain quality of rice; nevertheless, the exogenous application of plant growth regulators (PGRs) might alleviate the negative effects of high temperatures. In the present study, we investigated the responses of rice grain quality to exogenously applied PGRs under high day temperatures (HDT) and high night temperatures (HNT) under controlled conditions. Four ...
DNA fingerprinting techniques were used to type 273 isolates of Mycobacterium bovis from Australia, Canada, the Republic of Ireland, and Iran. The results of restriction fragment length polymorphism (RFLP) analysis with DNA probes from IS6110, the direct repeat (DR), and the polymorphic GC-rich sequence (PGRS) were compared with those of a new PCR-based method called spacer oligonucleotide typi...
