What are glandular trichomes?
Glandular trichomes are specialized hairs found on the surface of about 30% of all vascular plants and are responsible for a significant portion of a plant’s secondary chemistry.
What are Halophytic plants?
Halophytes are plants which naturally survive in salt-contaminated environments and can tolerate salinity concentrations as high as 1 M NaCl (Flowers and Colmer, 2008; Kumari et al., 2015). About 1% of the total flora of the world (both dicots and monocots) are halophytic plants.
What plants have salt glands?
Salt glands are found mostly on leaves of plants that grow on dry saline soils, on salt marsh grasses, and in a variety of mangroves, which are woody plants that inhabit tropical and subtropical intertidal zones (Flowers et al., 1986; Tomlinson, 1986).
What is Peltate trichome?
Peltate trichomes, consisting of a basal cell, a stalk cell and a 12-celled head, are distributed on the stem, leaf, corolla and outer side of calyx. Digitiform trichomes are just distributed on the outer side of corolla, consisting of 1 basal cell, 3 stalk cells and 1 head cell.
Is the trichome Septate?
The stalks of the trichome are septate. …
What is the most salt tolerant plant?

Are there plants that remove salt from soil?
Several halophyte species including grasses, shrubs, and trees can remove the salt from different kinds of salt-affected problematic soils through salt excluding, excreting, or accumulating by their morphological, anatomical, physiological adaptation in their organelle level and cellular level.
How do plants get rid of excess salt?
Plants that exclude salt prevent it from entering the membranes of their roots. In other plants that do end up containing excess salt, some accumulate it into older leaves so it can be shed with the leaves. Others excrete salt, in much higher concentration than seawater, through gland s on their leaves.
What do salt glands in plants do?
Salt glands are specialized adaptive structures found predominantly on the leaves and stems of halophytic species [1, 2]. They are considered to be efficient desalination devices capable of removing salts from the plant tissues via an energy-dependent secretion process [1].
Which plants are halophytes?
Some halophytes are:
- Anemopsis californica (yerba mansa, lizard tail)
- Atriplex (saltbush, orache, orach)
- Attalea speciosa (babassu)
- Panicum virgatum (switchgrass)
- Salicornia bigelovii (dwarf glasswort, pickleweed)
- Spartina alterniflora (smooth cordgrass)
- Tetragonia tetragonoides (warrigal greens, kÅkihi, sea spinach)
