“…Statistical methods such as PCA have been used to evaluate the systematic usefulness of pollen data (Akhila and Beevy, 2015;de Abreu et al, 2015;da Luz et al, 2015;Mezzonato-Pires et al, 2015). In the present study, PCA was used to explore the relationships between taxa.…”

Pollen morphological characteristics of 7 taxa of the genus Aruncus L. (Rosaceae) were examined using scanning electron microscopy (SEM) to evaluate the taxonomic implication within the genus. Aruncus pollen grains were monad, tri-colporate with granular membranes, small in size (P = 8.33−12.57 µm, E = 8.93−14.40 µm), amb is sub-circular to circular, suboblate to prolate-spheroidal in shape (P/E = 0.68-1.70). The sexine ornamentation in all studied taxa was basically striate but existence of perforation (striate-perforate: A. dioicus, A. dioicus var. acuminatus, A. dioicus var. astilboides, A. dioicus var. pubescens, A. dioicus var. vulgaris; striate-pstilate: A. dioicus var. aethusifolius, A. gombalanus) and the widths of muri and grooves varied according to the taxa. In particular, relatively short, and sharply crested muri being a distinct feature of A. dioicus var. acuminatus. As a result, the various combination of each pollen characteristics could be useful to identify the some taxa of the genus Aruncus.

“…Pollen size and pollen shape also can further give information concerning species identification (Krachai and Pornpongrungrueng 2015;House 2016;Noedoost et al 2021). The study noticed that pollen size and shape were the characters that helped to distinguish the taxa at the species level (Akhila and Beevy 2015). Based on pollen shape, most species of Strobilanthes s.l.…”

“…Exine ornamentation is an important taxonomical feature for determining species. However, this feature is often highly characteristic, consistent within taxa (Raza et al 2020) and helps to distinguish the taxa at the species level (Akhila and Beevy 2015). The observation of pollen sculpture (especially exine ornamentation) using SEM made it possible to determine which types of apertural membrane were found in the pollen grains that would otherwise be difficult to identify using LM.…”

“…They can be used to solve the taxonomic problems of plant groups, such as identification, taxa delimitation, classification and relationship assessment (Yao and Zhang 2016;Al-Hakimi et al 2017;Tripathi et al 2017;Ruiz-Domínguez et al 2019;Chen et al 2019;de Souza et al 2019;Ragho 2020). The pollen morphological characters such as polar axis length (P), equatorial diameter (E), P/E ratio, pollen sculpture or exine ornamentation (Via do Pico and Dematteis 2013;Ferrauto and Pavone 2014;Sarwar et al 2015;Al-Hakimi et al 2018), pollen size, pollen shape, exine thickness (Akhila and Beevy 2015;Krachai and Pornpongrungrueng 2015;Noedoost et al 2021) are valuable for distinguishing and identification of many plant groups.…”

Abstract. Suratman, Suranto, Muzzazinah, Purnomo. 2022. Pollen morphological characters variation among species of Strobilanthes s.l. from Sumatra, Indonesia and its taxonomic implications. Biodiversitas 23: 4636-4648. The objective of this study was to evaluate pollen morphological characters variation and its taxonomic value among species of Strobilanthes s.l. from Sumatra. A total of 32 species from four genera previously recognized within the subtribe Strobilanthineae were used for pollen morphology observations using Light Microscope (LM) and Scanning Electron Microscope (SEM). A total of ten pollen morphological characters (both quantitative and qualitative) were observed in this study. In general, a great variation occurs in the majority of investigated pollen morphological characters. A similarity dendrogram among species of Strobilanthes s.l. based on pollen morphological character data revealed two major clusters. Cluster I consist of 25 species that differed from species in Cluster II in having pollen type I, pollen type II and pollen type III with a similarity coefficient of 0.61. Cluster II consists of seven species and has pollen type IV, pollen type V, pollen type VI and pollen type VII with a similarity coefficient of 0.46. An identification key to the species of Strobilanthes s.l. based on pollen morphology is also established for easy discrimination of the investigated taxa. This study revealed that pollen morphology was taxonomically useful character for identification and taxa delimitation of Strobilanthes s.l., especially at the species level. The results of this study also support earlier works through molecular studies, statistical analysis, gross morphology observations and leaf anatomy studies that all segregate genera of the subtribe Strobilanthinae should be merged under a single and well-defined genus as Strobilanthes s.l.

“…The sesame capsule is rectangular in shape, 2–3 cm in length, and 6–12 mm in diameter, with longitudinal ribs on the surface and microscopic hairs on the epidermis. Sesame seeds are black or white, the black ones are called black sesame and the white ones are called white sesame [ 9 , 10 , 11 ]. The different forms of sesame seeds during growth are shown in Figure 2 .…”

Sesame (Sesamum indicum L.), of the Pedaliaceae family, is one of the first oil crops used in humans. It is widely grown and has a mellow flavor and high nutritional value, making it very popular in the diet. Sesame seeds are rich in protein and lipids and have many health benefits. A number of in vitro and in vivo studies and clinical trials have found sesame seeds to be rich in lignan-like active ingredients. They have antioxidant, cholesterol reduction, blood lipid regulation, liver and kidney protection, cardiovascular system protection, anti-inflammatory, anti-tumor, and other effects, which have great benefits to human health. In addition, the aqueous extract of sesame has been shown to be safe for animals. As an important medicinal and edible homologous food, sesame is used in various aspects of daily life such as food, feed, and cosmetics. The health food applications of sesame are increasing. This paper reviews the progress of research on the nutritional value, chemical composition, pharmacological effects, and processing uses of sesame to support the further development of more functionalities of sesame.
