Zinc (Zn) deficiency is the most widespread micronutrient disorder in rice (Oryza sativa), but efforts to develop cultivars with improved tolerance have been hampered by insufficient understanding of genetic factors contributing to tolerance. The objective of this paper was to examine alternative evaluation methods and to identify the most informative traits that would provide realistic informa...

Tropospheric ozone concentrations are increasing in many Asian countries and are expected to reach levels that adversely affect crop production. Developing ozone-tolerant rice (Oryza sativa L.) varieties is therefore essential to prevent yield losses in the future. The aims of this study were to assess genotypic variation for ozone tolerance in rice, to identify quantitative trait loci (QTL) co...

legume cultivation and production including chickpea is one of the main agricultural objectives in iran. chickpea crop is a good sources of protein consumption for human diet and play a significant role in nitrogen fixation in cultivated soil and also self reliance for iran economy. chickpea cultivated as a non irrigated crop in lorestan and hamadan provinces in iran. several virus diseases inf...

Boron (B) toxicity is a nutritional disorder affecting crop production in many parts of the world. This study explored genetic factors associated with B tolerance in rice (Oryza sativa L.) through an integrated genome mapping and transcriptomic approach. Variation in B tolerance was first evaluated by screening a panel of 137 indica genotypes in B toxic conditions (+2 mM B), followed by genome-...

Tetranychid outbreaks have been detected since 2016 in southern highbush blueberries (SHB); however, it was not until 2019 that the red mite (SRM), Oligonychus ilicis (Acari: Tetranychidae) confirmed as pest causing severe bronzing and stunting, multiple Florida Georgia commercial blueberry plantings. To date, only three miticides (fenazaquin, fenpyroximate, acequinocyl) registered for use SHB ...

Bronzing of strawberry (Fragaria ×ananassa Duchesne) fruit that is not the result of arthropod feeding or chemical spray application occurs frequently in California’s central coast strawberry production region from late spring through midsummer, a period characterized by relatively high temperature, low relative humidity, and high solar irradiance. The cause of this phenomenon is not known, but...

European red mites are the most frequent mite in Uzbekistan apple orchards, and they may be found from early spring through harvest. The orange-colored adults of twospotted spider overwinter beneath bark trees or on weeds. In spring, populations typically cluster tree nearby areas broadleaf weeds, brambles, sucker growth. Damage. Twospotted induce bronzing leaves. Spider leave a characteristic ...

During leaf development, the formation of leaf adaxial-abaxial polarity at the primordium stage is crucial for subsequent leaf expansion. However, little is known about the genetic control from polarity establishment to blade outgrowth. The leaf margin, comprising elongated margin cells and hydathodes, is thought to affect leaf expansion. Here, we show that mutants with defective leaf polarity ...
