HIGHLIGHTS This is the first anatomical investigation of Acmella bellidioides. The common name “arnica-do-campo” often applied to multiple species. Microscopy techniques were used characterize species’ structures. Peltate glandular trichome an marker for
neoseiulus californicus (mcgregor) is a predatory mite that can control spider mites. the effect of seven strawberry cultivars (including: ‘marak’, ‘yalova’, ‘aliso’, ‘gaviota’, ‘sequoia’, ‘camarosa’ and ‘chandler’) on the growth and development of n. californicus was studied in the laboratory conditions (27 ± 1 °c, 70 ± 5% rh and 16l: 8d photoperiod). there was significant difference in the nu...
Trichomes are differentiated epidermal cells on above ground organs of nearly all land plants. They play important protective roles as structural defenses upon biotic attacks such as herbivory, oviposition and fungal infections, and against abiotic stressors such as drought, heat, freezing, excess of light, and UV radiation. The pattern and density of trichomes is highly variable within natural...
Being an essential component in various metabolic activities, water is important for the survival of plants and animals. Cacti grown in arid areas have developed intrinsic water management systems, such as water collection through spines, water absorption through trichome, and water storage using mucilage. The water collection method of cactus is well-documented, but its water absorption and st...
A field experiment was conducted to study the relation of different plant characters and shoot fly resistance in sorghum. Leaf glossiness showed high positive correlation with shootfly oviposition and dead hearts. The oviposition percentage on 14 and 21 days after seedling emergence exhibited significant positive correlation with dead hearts. Leaf trichome density on adaxial and abaxial leaf su...
Adaptation of plants under drought and salinity stress depends directly on the type of soil texture. Therefore, in this research, the morpho-physiological variations of Stachys multicaulis, an Iranian wild endemic plant species, were investigated in different soil textures under drought and salinity stress. For this purpose, plants were cultivated in three different light, medium and h...

PII: S1360-1385(00)01597-1 In plants, the control of cell fate is a central issue during embryo development, meristem function and the transition from vegetative to reproductive phases. The regulation of cell fate requires a balance of cell proliferation, differentiation, intercellular co...
