Summary: Vascular shrubs growing along the draw-down zones of saline lakes have to develop adaptive mechanisms to cope with high salinity, erratic environmental conditions, and other stresses. Microbial endophytes from these plants play an important role in plant growth, health, and survival under stressful conditions. In this study, bacterial endophytes were isolated from shrubs growing along the draw-down zone of Lake Bogoria, and their potential for biocontrol of the bean root rot pathogen, Fusarium solani, was examined. Two isolates showed promising results in controlling the pathogen and promoting plant growth.

Summary: Salinity has a negative impact on crop production, affecting soil properties and ecological balance. Plant growth-promoting bacteria, such as Bacillus subtilis NA2, play a key role in controlling phytopathogens and abiotic stress. In a study comparing four wheat varieties under salt stress, plants primed with Bacillus subtilis NA2 showed improved growth and increased levels of carotenoids, anthocyanin, ascorbic acid, soluble proteins, chlorophyll contents, and peroxidase activity. Levels of malondialdehyde, hydrogen peroxide, catalase, and ascorbate peroxidase decreased. The study suggests that Bacillus subtilis NA2 can be beneficial for wheat yield under salinity stress by improving plant defense mechanisms.

Summary: The potential of plant growth-promoting endophytic fungi (PGPEF) in mycoremediation has gained attention. Two PGPEF isolates from Eupatorium triplinerve leaves were selected based on their ACCD activity and high Cd tolerance. These isolates exhibited IAA and GA production, phosphate solubilization, and siderophore production under Cd stress. Molecular identification confirmed them as species of Colletotrichum. FESEM-EDAX and AAS analyses further demonstrated their Cd bioaccumulation ability in mycelial cells and their impact on rice seedling growth. Successful root colonization was observed, and the detached leaf experiment confirmed their applicability on field-scale as non-pathogenic PGPEF candidates.

Summary: This study investigates the effects of cerium oxide nanomaterials (CeO2 NMs) on maize, and finds that CeO2 NMs can alleviate the impact of salt stress on maize. 10 mg/L CeO2 NMs can improve the salt tolerance of maize by maintaining the homeostasis of sodium and potassium ions, enhancing photosynthetic efficiency, and reducing reactive oxygen species levels. Transcriptomic analysis shows that CeO2 NMs eliminate salt-induced reactive oxygen species, facilitate leaf cell elongation. Additionally, CeO2 NMs increase the richness and diversity of rhizobacteria.

Summary: Carrot psylla females exhibited differential preferences towards different carrot germplasm, with wild accessions 21793 and 20465 being highly preferred. Volatile emissions from infested carrot cultivars differed qualitatively and quantitatively compared to intact plants, with certain volatiles like apiol, fl-asarone, myristicin, and sabinene showing associations with psylla growth and survival. Exogenous application of myristicin and sabinene led to a significant reduction in psylla oviposition and nymph survival. This study provides valuable information for developing new control strategies against carrot psylla.

Summary: This study evaluated genetic variation in wheat genotypes under salt stress to identify novel salt-tolerant resources for wheat improvement. The results showed that wheat genotypes exhibited different morphological and ionic traits under salt stress, but four genotypes showed consistent tolerance and proper Na+ and K+ discrimination in leaves. These tolerant genotypes maintained stable relative water content, chlorophyll, and photosynthesis rate, resulting in higher dry matter production under salt stress. Biomass, shoot K+, root Ca2+, and shoot K+/Na+ were identified as the most effective parameters for screening salt-tolerant wheat germplasm.
