Exploring The Role Of Stigmatic Exudate In The Water Lily (Nymphaceae) Pollination Mechanism Using N. Ampla (Salisb. Dc.), Luis Uribe
Theses and Dissertations
Water lilies are the only known plant group that uses hyperactive nectar glands to divest pollinators of their pollen. The nectar in Nymphaea ampla is thought to contain secondary metabolites that increase pollen deposition possibly by modifying pollinator behavior. This was explored utilizing visitation and fecundity data from the field coupled with survival and behavioral experiments in the laboratory. Replacing nectar with water reduced seed set in N. ampla which was attributed to reduced visitation in water-bearing flowers and not to effects on pollinator detention time. Exposure to nectar did not reduce survivability in Apis mellifera. Pollen and nectar foragers …
Larvicidal Effect Of Secondary Metabolites Of Three (Diptera:Culicidae)Fungi Againstcx.Quinquefasciatus, Ali A. H. Abdul Al-Ameer
Larvicidal Effect Of Secondary Metabolites Of Three (Diptera:Culicidae)Fungi Againstcx.Quinquefasciatus, Ali A. H. Abdul Al-Ameer
Al-Qadisiyah Journal of Pure Science
The larvicidal effect of secondary metabolites of Verticillum lecanii,Pencillium chrysogenum and Aspergillus niger against filaria vector Cx.quinquefasciatus was investigated. efficacies have been tested at four different concentrations of secondary metabolites of mentioned fungi (25,50,75,100)ppm .larvicidal efficacy demonstrates that larval mortality was related to concentration, exposure time and larval age. Higher mortality was observed at high concentration, moreover mortality increased when exposure time increased , additionally , the older larvae were more resistant to fungal filtrate. Also, it was perceptible that larvae of Cx.quinquefasciatus have a chieved higher mortality for V.lecanii, at the concentration (100ppm )after 24 ,48,and 72 hrs for …

Plants produce an enormous diversity of secondary metabolites, but the evolutionary mechanisms that maintain this diversity are still unclear. The interaction diversity hypothesis suggests that complex chemical phenotypes are maintained because different metabolites benefit plants in different pairwise interactions with a diversity of other organisms. In this synthesis, we extend the interaction diversity hypothesis to consider that fruits, as potential hotspots of interactions with both antagonists and mutualists, are likely important incubators of phytochemical diversity. We provide a case study focused on the Neotropical shrub Piper reticulatum that demonstrates: 1) secondary metabolites in fruits have complex and cascading effects for …

Moringa oleifera is a widely used crop that produces seeds with a plethora of benefits encompassing health and nutrition. Secondary metabolite compounds were determined in the seeds of Moringa oleifera that possess nutritional and pharmacological benefits. Although various phytochemical researchers reported the presence of secondary metabolites in M. oleifera seeds, there is a lack of research on the genes encoding for enzymes that catalyze the synthesis of secondary metabolites in the seeds of M. oleifera. In the present study, RNA sequencing was used to analyze the transcriptome of the mature seed embryos of M. oleifera. Biological pathway analysis …
