One possible explanation was that the experimental conditions varied between the assays for basal defense and DCA-mediated immunity. In contrast to the analysis of DCA-mediated immunity , there was no pre-treatment with compound or mock solution before being sprayed with pathogen in the basal defense assays . It was observed in other experiments that this type …

Citrus are rarely grown from seed and virtually all commercial citrus is propagated by grafting
Several transcription factors were differentially expressed in this study. GO enrichment showed the molecular function GO term ‘DNA-binding transcription factor activity’ was significantly enriched. In addition to the MYB77 transcription factor gene described earlier, a GRAS transcription factor gene, HAM3, was DE in this study. GRAS transcription factors were previously found to play a role …
Tubes were brought to water holding capacity before planting
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 …

All other cultural practices were standard for wheat production in the area
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, …

Students learn about the carbon cycle and soil carbon sequestration while building compost piles
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 …
Moving the conversation into the policy realm is vital
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 …

Pasture area is grazed rotationally and managed for optimal plant biomass communities
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 …
Iron deficiency leads to an enhancement of different ROS detoxification strategies
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 …
The Mycobacterium genus is often associated with HMW PAH biodegradation
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 …

Species from xeric environments also tend to be over-represented in drought tolerance studies
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 …
