Scanning electron imaging of mellitophilous and allergenic pollen grain of arid and northern irrigated agroecological zones of Pakistan

Abstract

Palynomorphic studies of 65 common mellitophilous and 16 allergenic flora of Arid and Northern irrigated agroecological zones of Pakistan are carried out in this study by using field emission scanning electron microscope (FESEM).Mellitophilous pollen were extracted from honey samples of selected sites. For collection of local allergenic pollen, previously identified allergy-causing plants were selected. Pollen morphological examination was carried out under FESEM.Diverse range of pollen shapes ranging from monad to polyad and sculpturing ranging from psilate to echinate, scabrate to reticulate, bireticulate, or echinolophate were observed. Brassicaceae, Myrtaceae, Asteraceae, Rosaceae, and Poaceae were observed to be dominant allergenic and mellitophilous families of the selected sites.

“…The results of present investigation were collected using technique of García-Mozo, 2017;Noor & Ahmad, 2021;Sapiña et al, 2021). LM and SEM analysis has been used for study of pollen exine sculpturing (Bahadur et al, 2018;Guimarães et al, 2018).…”

“…Using microscopic techniques of LM and SEM Pollen morphology of allergenic plant family Poaceae was taken out in Pakistan first time which show pollen were porate and their exine ornamentation vary (Ullah, Ahmad, et al, 2021; Ullah, Zafar, et al, 2021). Noor and Ahmad (2021) studied Palyno‐morphic character of 16 allergenic flora of Northern and Arid irrigated agroecological zones of Pakistan.…”

“…minor allergenic plants species like families of Fagaceae, Salicaceae, or Ulmaceae showing typical pollen wall organization with compact endexine, intine, and ektexine while majority of allergenic plants species like Poaceae and Betulaceae the endexine is not detectable(Diethart et al, 2007). Using microscopic techniques of LM and SEM Pollen morphology of allergenic plant family Poaceae was taken out in Pakistan first time which show pollen were porate and their exine ornamentation varyUllah, Zafar, et al, 2021) Noor and Ahmad (2021). studied Palyno-morphic character of 16 allergenic flora of Northern and Arid irrigated agroecological zones of Pakistan.…”

Micromorphological considerations on Alyssum nezaketiae Aytaç & H. Duman (Brassicaceae), endemic to gypsum habitats from Turkey: An electron microscopic study

“…Abiotic stress responses of different gypsophyte were extensively studied at the phytochemical and molecular level. Macromorphological and complementary microscope‐based techniques are helpful in interpreting the response of plants to abiotic stress at the anatomical and ultrastructural level (Han et al, 2021; Khan & Khan, 2020; Kim, 2018; Mani, Rasangam, Selvam, & Shekhawat, 2021; Nazir et al, 2021; Nazish et al, 2019; Noor & Ahmad, 2021; Öztürk Çalı & Karavin, 2020; Sadia et al, 2020; Salem‐Fnayou, Bouamama, Ghorbel, & Mliki, 2011; Scocco, Mercati, Tardella, & Catorci, 2016). While plant adaptation to changing environmental conditions can be associated with the organization of leaves, presence of a protective outer layer of the epidermis and cuticle, and properties of the stomata (Salem‐Fnayou et al, 2011), few reports described the anatomical and ultrastructural changes that characterize gypsophytes.…”

“…Supporting macromorphological features with LM and SEM microscope-based processes is very beneficial in interpreting the response of plants to environmental stress (Kim, 2018;Khan and Khan, 2020;Sadia et al, 2020;Han et al, 2021;Mani et al, 2021;Nazir et al, 2021;Noor and Ahmad, 2021). There are recent studies with SEM of members of the Fabaceae family, but SEM studies that interpret adaptation to abiotic stress are insufficient (Bacchetta et al, 2020;Shaheen et al, 2020;Abusaief and Boasoul, 2021;Guerrero et al, 2021;Kashyap et al, 2021;Soares et al, 2021).…”
