In their findings, as root biomass increased beyond a certain threshold it negatively impacted grain yields, perhaps due to increased costs of maintaining a large root system. This point appears worthy of detailed study as it may point to which root system traits will be beneficial in a given environment and how they might impact …

Cultivars Sonora, Foisy, and Chiddam Blanc de Mars were selected. The primary criterion was the total root biomass with Sonora ranked among the highest, Foisy was intermediate, and CBdeM had a low total root biomass. Additionally, the three also have other contrasting phenotypes for traits such as drought tolerance, plant height, days to heading, awn type, …

Food is a powerful frame through which to make the climate change problem more concrete and “close to home,” as it implies both a social and essential daily activity. The garden, meanwhile, provides a useful metaphor for the complex global climate system. The curriculum directly connects climate science to community and local action in the …
Civic engagement advances the idea of creating “public commons” through urban agriculture, an idea related to ecological economics and explored in David Bollier’s book Think Like a Commoner: A Short Introduction to the Life of the Commons. A commons “integrates economic production, social cooperation, personal participation, and ethical idealism into a single package;” it is …

The program uses an “integrated systems approach” to delivering hands-on education in nutrition, ecology, sustainability, and land stewardship . In practice, this consists of educating students in a garden classroom elective for elementary and middle school, hosting a high school farm elective course where students visit local farms, and preparing and preserving food from the …
Transcriptomic and proteomic studies in Fe deficient plants have also reported increases in root transcript and protein abundances, respectively, of enzymes related to the glycolytic and TCA cycle pathways, among others. Iron deficiency also induces an accumulation of organic acids, mainly malate and citrate, in roots. The induction of C metabolism in roots of Fe-deficient plants …
Approximately 20 g of Ottawa sand was spread across the soil and the lid was placed on the Petri dish and sealed with parafilm to maintain optimal growth conditions. A sandy loam control soil containing no PAH contamination was prepared in the same manner every 20 samples. The samples were placed in a growth chamber …
In the absence of major decomposition pathways, PAHs are removed from the atmosphere by dry and wet deposition, which is considered the major source of PAHs in soil . Although PAHs are considered amongst the most widespread organic pollutants in numerous environmental matrices such as soils, sediments, water, and wastewater, the ultimate sink of atmospheric …

The combination of these approaches is useful for the identification of genes and traits under selection in natural settings, but so far few studies have taken this approach. Eckert et al. tested the association of SNPs with five phenotypic traits and 11 environmental variables across 10 P. lambertiana populations around Lake Tahoe. This study identified six …
The region of Araraquara has the largest insect Las+ population in summer, while Bebedouro has the smallest, during the whole year. The Asian citrus psyllid is the only known vector of the bacterium, ‘Candidatus’ Liberibacter asiaticus , that causes huanglongbing or citrus greening disease. This insect acquires CLas from an infected citrus tree while feeding …
