Possible Role of Biogenic Amines in Plant–Animal Relations
Published in Akula Ramakrishna, Victoria V. Roshchina, Neurotransmitters in Plants, 2018
The first information about biogenic amines in plants appeared in the middle of the twentieth century. At the beginning, Werle and Raubb (1948) published a list of plants containing histamine. Later, similar information was revised for catecholamines (Roshchina 1991, 2001). Even Stanley and Linskens (1974) attracted attention to histamine being found in pollen, mainly of wind-pollinated species Agrostis alba, Alopecurus pratensis, Bromus erectus, Corylus avellana, Cynosurus cristatus, Dactylis glomerata, Gelsemium sempervirens, Lolium perenne, Phleum pratense, Poa pratensis, Secale cereale, Zea mays, as well as of some insect-pollinated species Syringa vulgaris, Tilia platyphyllos, and T. cordata (Marquardt and Vogg 1952). Later, pollen Acer platanoides L., Anemone ranunculoides L., Anthriscus sylvestris L., Betula verrucosa Ehrh., Corylus avellana L., Larix decidua Mill., Hippeastrum hybridum L., Narcissus pseudonarcissus L., Picea excelsior (excelsa) L., Pinus sylvestris L., Philadelphus grandiflorus Willd., Phleum pratense L., Plantago major L., Populus balsamifera L., Quercus robur L., Rubus odoratus L., Syringa vulgaris L., Taraxacum officinale L., Tilia cordata Mill., Tussilago farfara L., Tulipa sp., and Urtica dioica L. were collected (from different ecosystems: grasslands, meadow, parks, groves) during June−August, and greenhouse plants Aloe vera L., Epiphyllum hybridum L., Hibiscus rosa-sinensis L., Hippeastrum hybridum were studied (Roshchina 2014; Roshchina and Yashin 2014). Dopamine and histamine play roles in signaling at the interaction of pollen and pistil during fertilization (Roshchina and Melnikova 1998).

This study clearly demonstrated that the synthesized IH-AgNPs are non-toxic and biocompatible towards normal CHO cells and are potent cytotoxic against cancer cell lines. Our results are in line with the many previous reports portrayed the anticancer activity of AgNPs synthesized using different plant extracts. AgNPs synthesized using Olax scandens showed effective cytotoxicity against different cancer cells including B16F10, A549 (human lung carcinoma) and MCF-7 (human breast cancer) and they showed biocompatibility towards normal cells including CHO, H9C2 (rat cardiomyoblast), and HUVEC (human umbilical vein endothelial cells) [5]. AgNPs from Panax ginseng showed broad spectrum cytotoxicity against different cell lines including A549, HepG2 (Hepatic carcinoma) and MCF-7 cells [42]. AgNPs from Clerodendrum phlomidis showed significant cytotoxicity against HT29 (human colorectal adenocarcinoma) and EAC (Ehrlich ascites carcinoma) cells [57]. Biosynthesized AgNPs using Gymnema sylvestre and Rubus glaucus leaves showed effective cytotoxicity against HepG2 cell lines [58,59]. Biosynthesized AgNPs using Hydrastis canadensis, Gelsemium sempervirens, Phytolacca decandra, and Thuja occidentalis showed anticancer activity against A375 (skin melanoma) by arresting G2/M phase of cell cycle [60].
