The fungicidal properties of plant seed peptides from Heuchera sanginea (Hs-AFP1), Raphanus sativus (EA-AFP2), and Impatiens balsamina (Ib-AMP3) were determined for the non-germinated and germinated conidia of Aspergillus flavus and Fusarium moniliforme. These peptides were weakly lethal for germinated but not for non-germinated conidia of A. flavus. Both non-germinated and germinated conidia of F. moniliforme were susceptible to these peptides. Overall, F. moniliforme was more susceptible than A. flavus to the peptides. The peptides bound strongly to chitin, mannan, galactocerebrosides, and sphingomyelin. Binding results varied for ergosterol, cholesterol, and beta1,3-glucan.

Article Synopsis
  • The text discusses the difficulty in accurately detecting rice seed germination rates due to the similarity between germinated and non-germinated seeds.
  • It introduces a new model called Rice Seed Germination-YOLOV8 (RSG-YOLOV8), which utilizes advanced techniques like CSPDenseNet, a dynamic attention mechanism, and structured feature fusion to enhance detection efficiency and accuracy.
  • Experimental results show that RSG-YOLOV8 achieves a mAP50 score of 0.981, surpassing the previous standard set by YOLOv8 by 4%, establishing a new benchmark in the field.

Departamento de Biología Vegetal y Ecología, Facultad de Biología, Universidad de Sevilla, Profesor García González s/n, E-41012, Sevilla, Spain.

Background And Aims: Crithmum maritimum is a wild, edible halophyte with large potential as a cash crop for salinized soils. However, its tolerance during seed germination appears to be highly site-specific and contradictory, whereas little is known on salinity tolerance during early seedling growth. This study aimed to characterize variation in the responses of germination and early seedling growth in diverse C.

Faba bean is a promising source of ingredients for the production of meat analogs. However, sensory properties of faba bean, especially the bitter taste of the protein concentrate, restrict its use. Our aim was to assess the feasibility of two types of faba bean ingredients-flour (from germinated, gently heat-treated beans) and groat (from non-germinated, roasted beans)-in combination with pea protein isolate and oat fiber concentrate for producing meat analogs using high-moisture extrusion.

Introduction: Previous studies have shown that the velvet bean, an indigenous legume in Indonesia, possesses high protein content and bioactive compounds. However, the utilization of velvet beans in tempe production remains underexplored.

Methods: This study aims to address this research gap by investigating the physicochemical properties and sensory profiles of tempe made from velvet beans, both individually and in combination with soybean.
