Evaluation of the altered enzymatic and pollen activity in sunflower on application of nanoparticles.
Plant Physiol Biochem
January 2025
Department of Agronomy, UAS, GKVK, Bengaluru, India.
Nanoparticles play a significant role in enhancing crop yield and reducing nutrient loss through precise nutrient delivery mechanisms. However, it is imperative to ascertain the specific plant physiology altered by these nanoparticles. This study investigates the effects of green-synthesized nanoparticles, specifically boron nitride and sulphur, on sunflower yield, seed quality, and physiological activities.

Division of Allergology and Clinical Immunology, Department of Medicine, University of Cape Town, Cape Town, South Africa.
Background: Ragweed is an invasive, highly allergenic weed predicted to expand its habitat with warming global temperatures. Several species have been identified in South Africa for well over a century; however, its presence remained undetected by allergists and aerobiologists until the development of an extensive aerospora monitoring system across South African urban areas since 2019. This paper presents the inventory of preliminary investigation of the airborne pollen and the taxonomic identification of ragweed species.

November 2024
State Key Laboratory of Complex Severe and Rare Diseases, Department of Allergy, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.
Background: Pollen is the most common outdoor allergen that causes allergic rhinitis and asthma, which seriously affects patient quality of life and extensive cross-reactivity occurs between pollen allergens.
Methods: The study enrolled 84 patients with respiratory allergies and at least one pollen allergy who visited the clinic. Specific-IgE was detected via immunoblotting in the sera of patients with positive respiratory allergies to pollen.
Effects and Related Mechanisms of Allelopathy of 's Pollens on Corn Pollens, Stigmas, and Yield.

, a worldwide malignant invasive weed, can inhibit corn seed germination, seedling growth, and yield through allelopathy. However, it is unclear whether it can inhibit activities of corn pollens and stigmas and, thus, decrease corn yield through allelopathy. Here, we studied the allelopathic effects and related mechanisms of 's pollens on corn pollens, stigmas, and yield.
