New Perspective on the Use of α-Bisabolol for Weed Control.

The indiscriminate use of synthetic herbicides reduces its effectiveness. Bioherbicides produced with metabolites emerge as an alternative to managing weeds. We aimed to analyze the phytotoxic potential of the essential oil of (EOVA) and the α-bisabolol molecule, its main component.

KI Increases Tomato Fruit Quality and Water Deficit Tolerance by Improving Antioxidant Enzyme Activity and Amino Acid Accumulation: A Priming Effect or Relief during Stress?

A water deficit can negatively impact fruit yield and quality, affecting critical physiological processes. Strategies to mitigate water deficits are crucial to global food security. Iodine (I) may increase the efficiency of the antioxidant system of plants, but its role against water deficits is poorly understood.

Soybean Plants Exposed to Low Concentrations of Potassium Iodide Have Better Tolerance to Water Deficit through the Antioxidant Enzymatic System and Photosynthesis Modulation.

Water deficit inhibits plant growth by affecting several physiological processes, which leads to the overproduction of reactive oxygen species (ROS) that may cause oxidative stress. In this regard, iodine (I) is already known to possibly enhance the antioxidant defense system of plants and promote photosynthetic improvements under adverse conditions. However, its direct effect on water deficit responses has not yet been demonstrated.

Nitrogen sources and CO concentration synergistically affect the growth and metabolism of tobacco plants.

The initial stimulation of photosynthesis under elevated CO concentrations (eCO) is often followed by a decline in photosynthesis, known as CO acclimation. Changes in N levels under eCO can have different effects in plants fertilized with nitrate (NO) or ammonium (NH) as the N source. NO assimilation consumes approximately 25% of the energy produced by an expanded leaf, whereas NH requires less energy to be incorporated into organic compounds.

Biomass Accumulation and Cell Wall Structure of Rice Plants Overexpressing a Dirigent-Jacalin of Sugarcane () Under Varying Conditions of Water Availability.

A sugarcane gene encoding a , , was induced under drought stress. To elucidate its biological function, we integrated a -overexpression construction into the rice Nipponbare genome via -mediated transformation. Two transgenic lines with a single copy gene in T were selected and evaluated in both the T and T generations.

Structural and functional changes in coffee trees after 4 years under free air CO2 enrichment.

Background And Aims: Climate forecasts suggest that [CO2] in the atmosphere will continue to increase. Structural and ecophysiological responses to elevated air [CO2] (e[CO2]) in tree species are contradictory due to species-dependent responses and relatively short-term experiments. It was hypothesized that long-term exposure (4 year) to e[CO2] would change canopy structure and function of Coffea arabica trees.

Reference genes for normalization of qPCR assays in sugarcane plants under water deficit.

Background: Sugarcane ( spp.) is the main raw material for sugar and ethanol production. Among the abiotic stress, drought is the main one that negatively impact sugarcane yield.

Physiological and transcriptional analyses of developmental stages along sugarcane leaf.

Background: Sugarcane is one of the major crops worldwide. It is cultivated in over 100 countries on 22 million ha. The complex genetic architecture and the lack of a complete genomic sequence in sugarcane hamper the adoption of molecular approaches to study its physiology and to develop new varieties.
