“…Çıtak and Dural (2020) reported that some species of the genus Iberis had parenchymatous cells in the root center [15]. The contour of the stem cross-sections was rounded with collenchymatic ridges that were ovoid or polygonal in the family Brassicaceae [15][16][17][18], while they were rectangular-and irregular-shaped in Diplotaxis harra [10]. The rounded-shaped cross-section of the stem in D. tenuifolia was observed with the general characteristics of the primary stem.…”

The present study deals with the morphological, anatomical, and palynological properties of Diplotaxis tenuifolia. The stem cross-sections had a single-layered epidermis, parenchymatous cortex, vascular bundles, and parenchymatic pith cells. An equifacial mesophyll type was observed in the leaves with multiple-layered palisade tissue, but the spongy parenchyma was reduced. Vascular bundles were small except for the midrib. The cross-sections of the fruit had a single exocarp, 3-or 4-layered mesocarp, and single-layered endocarp. Transverse sections of the seed showed the presence of layers of epidermis, parenchyma, and endosperm.

“…The macro-and micromorphology of the seeds were determined as the most distinctive characters for distinguishing the eight Iberis taxa. The seed colour and size, and ornamentation provided great potential for distinguishing seed morphological variations at species level as in previous studies (Barthlott 1984, Khalik & van der Maesen 2002, Pinar et al 2007, Ghaempanah et al 2013, Atçeken et al 2016, Karaismailoğlu & Erol 2018, Karaismailoğlu 2019, Gönen et al 2019). In the current study, the light brown-yellow seed colour in I. saxatilis subsp.…”

“…The features of the seed coat, such as surface sculpturing, anticlinal and periclinal wall cells, and epidermal cell shape have been determined as useful in the delimitation of taxa within some genera in the family Brassicaceae (Moazzeni et al 2007, Atçeken et al 2016, Gabr 2018, Karaismailoğlu & Erol 2018, Karaismailoğlu 2019, Gönen et al 2019. In this research, the seed coat ornamentation, which was reticulate, reticulate-rugose and reticulate-papillate can be considered essential diagnostic features at species level.…”

“…For example, reticulate-rugose seed coat is distinctive in I. odorata, while reticulate-papillate is unique in I. simplex. In Brassicaceae, reticulate surface ornamentation is the most common character at the generic level (Zeng et al 2004, Moazzeni et al 2007, Atçeken et al 2016, Karaismailoğlu & Erol 2018, Karaismailoğlu 2019, Gönen et al 2019 as it was confirmed since six of the eight taxa studied show reticulate seed coat. In taxonomy, epidermal cell shape on the seed surface is important at generic and also subgeneric level in the family Brassicaceae (Karaismailoğlu 2019).…”

“…This study examined the utility of using the fruit and seed micromorphology of Iberis species in Turkey. The sculpturing of surfaces has been used for problems in taxonomy to observe relationships of species in Brassicaceae , Khalik et al 2002, Pinar et al 2007, Atçeken et al 2016, Karaismailoğlu & Erol 2018, Karaismailoğlu 2019, Gönen et al 2019. The outcomes showed that the seed micromorphology was more useful than fruit micromorphology to separate Iberis taxa in Turkey.…”

Background: This paper investigates whether the fruit and seed micromorphology of eight Turkish Iberis (Brassicaceae) species can be used as a further aid in their taxonomic delimitation. Questions: Are the micro-morphological characters of the fruits and seeds of Iberis useful to support the taxonomic delimitation of its species? Studied species / data description /Mathematical model: The eight species of Iberis present in Turkey were examined. The fruit and seed characteristics were obtained and statistical analysis was performed using UPGMA. Study site and dates: Fifteen localities in Turkey, from 2015 to 2019. Methods: Samples of fruit and seed of eight species of Iberis were collected, stored, and later measured and described with aid of light and scanning electron microscopies. Results: All eight species had different fruit and seed characters; particularly differing from each other with respect to fruit and seed size, seed shape and seed ornamentation. Two fruit ornamentation types were evident, smooth and striated. The seed coat surface were separated into three types: reticulate, reticulate-rugose and reticulate-papillate, being reticulate the most common. Further differences were noted for the seed surface epidermal structures, notably species had rectangular, tetragonal, or pentagonal patterning. An identification key was constructed based on a similarity analysis. Conclusions: Fruit morphology, seed dimensions, colour, and epidermal cell patterning are useful microcharacters that enabled species-level determinations in the Iberis species sampled.

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

Alyssum nezaketiae is a local endemic species in gypsum habitats of Çankırı province in Turkey. In this study, I used field collected specimens of A. nezaketiae in a scanning electron microscopy examination of vegetative and reproductive structures of A. nezaketiae. The objective of the study was to investigate the micromorphological properties that define the species and that represent its adaptation(s) to the extreme environmental conditions posed by gypsum habitats. The epidermis had one to two rows at transverse sections of leaf and stem. Cortex was composed six to eight rows parenchyma cells at stem. A number of adaptations to xeric habitats were observed, including: dense silvery lepidote hairs on leaves and stems, small leaves, stomata on the lower surfaces of the leaves occurring in stomatal crypts, intense lignification in the central cylinder of the stems, and bundles of sclerenchyma in the pith region of stems. These can be interpreted as gypsophytic characteristics associated with physiological drought. Micromorphological properties of plant parts are discussed in relation to environmental conditions and possible constraint factors occurring in these gypsum habitats. Furthermore, these micromorphological studies contribute important taxonomic characters that are needed to help identify a species whose habitat is under threat from a variety of human activities.
