Ozone is a powerful oxidizing agent which is responsible for more damage to vegetation than any other air pollutant. In this study, leaf growth, photosynthesis, and carbohydrate content were analysed during the seed-filling growth stage of field-grown soybeans exposed to ambient air and 1.2 times ambient ozone concentration using a Free Air Concentration Enrichment (FACE) facility. By contrast ...

Soybeans represent a recent and powerful threat to tropical biodiversity in Brazil. Developing effective strategies to contain and minimize the environmental impact of soybean cultivation requires understanding of both the forces that drive the soybean advance and the many ways that soybeans and their associated infrastructure catalyse destructive processes. The present paper presents an up-to-...

Agriculture in Canada was substantively transformed in the past century. In absolute terms, agricultural production increased considerably. For example, production of wheat, a major Canadian crop, based initially on the improved variety Marquis, trebled from 1908 to 2008. New crops, such as canola—improved varieties of rapeseed—on the Prairies and soybeans in Ontario, are now widely grown. Simi...

BACKGROUND The Bean plataspid (Megacopta cribraria) (Hemiptera: Pentatomidae), native to Asia, is becoming an invasive species in North America; its potential spread to soybean producing areas in the US is of great concern. Ecological niche modelling (ENM) has been used increasingly in predicting invasive species' potential distribution; however, poor niche model transferability was sometimes r...

The Dectes stem borer, Dectes texanus LeConte (Coleoptera: Cerambycidae), is currently receiving increased attention as a pest of soybeans in the Great Plains of North America. Field surveys were conducted in 1999 and in 2008 to record the distribution of this pest in Kansas. These surveys documented an increase in the abundance of the pest and an expansion in the range of this insect westward ...

Soybean ranks among the "big 8" of the most allergenic foods, and with increasing consumption of soybean products, the incidence of soy-caused allergies is expected to escalate. Soybean and its derivatives have become ubiquitous in vegetarian and many meat-based food products, and as a result, dietary avoidance has become difficult. However, soybeans can be manipulated in a variety of ways to a...

Packaging types as influencing seed quality in some soybean [Glycine max (L.) Merr.] varieties during storage period | Ratna Wylis Arief, Robet Asnawi, Reny D. Tambunan, Nila Wardani, Dewi Rumbaina Mustikawati, Made Jana Mejaya Agricultural Journals

Small RNAs, including microRNAs (miRNAs) and phased small interfering RNAs (phasiRNAs; from PHAS loci), play key roles in plant development. Cultivated soybean, Glycine max, contributes a great deal to food production, but, compared to its wild kin, Glycine soja, it may lose some genetic information during domestication. In this work, we analyzed the sRNA profiles of different tissues in both c...

ONCEPTS for the partitioning of genetic variability for a mating population 'were developed by FISHER (1918) and have been extended under varying assumptions by numerous authors. Quantification of the nonallelic gene interactions was presented by COCKERHAM (1954) and HORNER, COMSTOCK and ROBINSON (1955). The comments in this paper are modifications of COCKERHAM (1954). Partitioning of genetic v...

Seed treatments with Bacillus cereus UW85 increased nodulation of soybeans in three field seasons and in three different sterilized soils in the growth chamber. In the field, 28 and 35 days after planting, UW85-treated plants had 31 to 133% more nodules than untreated plants. From 49 days after planting until seed harvest, there were no significant differences between nodulation of UW85-treated...
