“…The leaf surface has glandular hairs on stem and leaf cells are filled with druse crystals. Ecological and anatomical comparative adaptability studies in Astragalus semnanensis were carried out by Rabizadeh et al (2019). They reported that adaptability of leaf surface is in the form of long and dense hairs.…”

“…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. Those published thus far reveal the presence of gypsum crystals on the trichomes and glandular hairs on stems as well as leaves (Rabizadeh, 2020a; Rabizadeh, 2020b; Rabizadeh, Zare‐Maivan, & Kazempour, 2019).…”

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.

“…by Abd El-Maboud and Abd Elbar (2020). In several reports, xerophytic features such as the organization of leaves, the presence of a protective outer layer of the epidermis and cuticle and the characteristics of stomata, the presence of gypsum crystals on stems, trichomes and glandular hairs as well as leaves have been interpreted by the anatomical and ultrastructural features of the plant, in the adaptation of gypsophiles to changing environmental conditions (Rabizadeh et al, 2019;Rabizadeh, 2020a;Rabizadeh, 2020b).…”

Jipsli Habitatlarda Doğal Olarak Yetişen Onobrychis germanicopolitana Hub.-Mor. & Simon (Fabaceae)'nın Ultrayapısal Bulguları ve Uyarlanabilir Yanıtları Ayşenur KAYABAŞ 1* ÖZET: Onobrychis germanicopolitana Hub.-Mor. & Simon, Çankırı'da jipsli alanlara endemik çok yıllık bir bitkidir. O. germanicopolitana'nın vejetatif ve generatif organları üzerindeki taramalı elektron mikroskobu (SEM) gözlemleri, bitkinin jipsli habitatların belirli koşullarına adaptasyonlarını gösteren ultrayapısal özellikler hakkında ayrıntılı bilgiler sunmuştur. Yaprakların ultrayapısal çalışması, üst yüzeyde daha fazla stoma varlığı ile amfistomatik olduklarını, yoğun yüzey tüylerine sahip olduklarını ve palizat parankimasının (~110 µm) sünger parankimasından (~60 µm) daha geniş olduğunu ortaya çıkarmıştır. Gövdenin enine kesitlerinde sekonder yapı görülmüş ve kambiyum açıkça ayırt edilmiştir. Kök, bir korteks ve periderm ile çevrili büyük vasküler silindirin varlığını göstermiştir. Kaliksin tabanındaki tüy yoğunluğu oldukça fazladır ve kaliks epidermisinin dış yüzeyi altıgen hücrelerden oluşmuştur. Veksillumun dış yüzeyi girinti ve çıkıntı şeklinde kutikular çizgilere sahiptir. Diğer adaptasyon özelliklerine ek olarak, yaprak, gövde ve meyvelerde bol miktarda bulunan tüyler papiller çıkıntılara sahiptir. O. germanicopolitana'nın detaylı betimsel ultrayapısal özellikleri ilk kez bu çalışmada bilgi ve referans kaynağı olarak verilmiştir.
