A Systematic Approach to Field Testing of Biological Products for Horticulture Is Required to Improve Food Security

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Food security challenges require immediate action to increase food production. Many biological products derived from plant, animal or microbial sources claim they sustainably increase yield, but there are concerns about biosecurity to be investigated before their introduction to the field.

Fluorescent proteins: A journey from the cell to extreme environments in material science

Photochemistry and Photobiology, Volume 102, Issue 2, Page 290-302, March/April 2026.
Applications of proteins and microorganisms as tools or effectors in material science. Abstract This review presents the progression from the use of fluorescent proteins (FPs) and chromoproteins as bioimaging labels and sensors to the strategic engineering of their properties for robust functionality in synthetic and non‐biological environments ...

Non‐ Conventional Agents Enhance Sweet Pepper (Capsicum annuum L. var. annuum) Defense against Aphis Gossypii, Thrips Tabaci, and Their Predators Chrysoperla Carnea and Orius Insidiosus

Global Challenges, Volume 10, Issue 2, February 2026.
ABSTRACT A study conducted in Egypt evaluated the effectiveness of chemical and microbial agents in enhancing sweet pepper (Capsicum annuum var. annuum) defenses against major pests Aphis gossypii and Thrips tabaci and their natural predators, Chrysoperla carnea and Orius insidiosus. Five foliar treatments were tested under greenhouse conditions during

The pio Operon Is Essential for Phototrophic Fe(II) Oxidation in Rhodopseudomonas palustris TIE-1 [PDF]

, 2006
Phototrophic Fe(II)-oxidizing bacteria couple the oxidation of ferrous iron [Fe(II)] to reductive CO2 fixation by using light energy, but until recently, little has been understood about the molecular basis for this process. Here we report the discovery,

Pea and canola enrich distinct rhizosphere bacterial communities even under intercropping

Ecosphere, Volume 17, Issue 1, January 2026.
Abstract Microorganisms have implications for plant health and agricultural production, yet we are just beginning to understand the complexity of plant–microbe interactions in multispecies environments. Studies conducted to date have shown that plants are able to control the makeup of their microbial communities, yet their ability to control these ...

Soil Phosphatase Enzyme Activity as Influenced by Agro‐Ecological Zones in Central Nepal

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Soil is a dynamic ecosystem that sustains a diverse community of organisms, enhancing its vitality and functions. Biochemical processes within the soil contribute to its active nature, with enzymes produced by organisms and plants playing roles in reactions. Phosphatases hydrolyze organic phosphorus to plant‐available phosphate ions.
