Functional synergy and genomic linkage of glyphosate resistance traits in Canada fleabane.

Background: Glyphosate resistance in Conyza canadensis (Canada fleabane) has been primarily attributed to non-target-site resistance (NTSR) mechanisms such as vacuolar sequestration, though these have not been formally elucidated. While a target-site mutation at EPSPS2 (P106S) was recently identified, it failed to account for many resistant cases. These findings underscore the need to re-evaluate the genetic basis of glyphosate resistance in this species.

Cannabinoid Distribution and Clearance in Feeding Spent Hemp Biomass to Dairy Cows and the Potential Exposure to Δ-THC by Consuming Milk.

Spent hemp biomass (SHB) is the byproduct of the cannabinoid extraction from hemp. Despite having an excellent nutritional profile, it cannot legally be used as a feed ingredient in livestock mainly due to the presence of Δ-tetrahydrocannabinol (Δ-THC), which could accumulate in animal products, posing a risk for consumers. This study investigated the accumulation and clearance of cannabinoids in milk and tissues of dairy cows fed SHB and the risk for people consuming the milk from those cows.

Changes in microbial community structure during adaptation of kombucha symbiotic culture of bacteria and yeast to fermentation of sweet and acid whey.

Whey is a liquid byproduct from the dairy industry that is not fully utilized and can be problematic to dispose of. Based on its composition, there is potential to upcycle whey into fermented beverages for human consumption. Most focus to date has been upon alcoholic fermentation to generate alcohol for distillation, or use of kefir grains to make acidic beverages.

Multidisciplinary evaluation of plant growth promoting rhizobacteria on soil microbiome and strawberry quality.

The natural soil environment is considered one of the most diverse habitats containing numerous bacteria, fungi, and larger organisms such as nematodes, insects, or rodents. Rhizosphere bacteria play vital roles in plant nutrition and the growth promotion of their host plant. The aim of this study was to evaluate the effects of three plant growth-promoting rhizobacteria (PGPR), Bacillus subtilis, Bacillus amyloliquefaciens, and Pseudomonas monteilii for their potential role as a biofertilizer.

Light Spectra and Root Stocks Affect Response of Greenhouse Tomatoes to Long Photoperiod of Supplemental Lighting.

Plant biomass and yield are largely dictated by the total amount of light intercepted by the plant (daily light integral (DLI)-intensity × photoperiod). It is more economical to supply the desired DLI with a long photoperiod of low-intensity light because it uses fewer light fixtures, reducing capital costs. Furthermore, heat released by the light fixtures under a long photoperiod extended well into the night helps to meet the heating requirement during the night.

Alternating Red and Blue Light-Emitting Diodes Allows for Injury-Free Tomato Production With Continuous Lighting.

Plant biomass is largely dictated by the total amount of light intercepted by the plant [daily light integral (DLI) - intensity × photoperiod]. Continuous light (CL, 24 h lighting) has been hypothesized to increase plant biomass and yield if CL does not cause any injury. However, lighting longer than 18 h causes leaf injury in tomato characterized by interveinal chlorosis and yield is no longer increased with further photoperiod extension in tomatoes.
