Tetralobulate glandular trichomes are present on the foliage of many solanaceous species. Resistance of many of these species to insects is conditioned by the ability of trichomes to rupture upon contact and to rapidly polymerize their contents, resulting in entrapment of insects in hardened trichome exudate. In the wild potato, Solanum berthaultii, polymerization of trichome exudate is initiat...

The production and distribution of plant trichomes is temporally and spatially regulated. After entering into the flowering stage, Arabidopsis thaliana plants have progressively reduced numbers of trichomes on the inflorescence stem, and the floral organs are nearly glabrous. We show here that SQUAMOSA PROMOTER BINDING PROTEIN LIKE (SPL) genes, which define an endogenous flowering pathway and a...

Lavandula dentata L., popularly known as lavender, is considered to be a medicinal plant that has great economic potential. The aims of the present study were characterize morphology L. grown in Paraíba do Sul, Rio de Janeiro, Brazil and determine content chemical composition its essential oil. Morphology was determined using optical microscope, digital calliper measuring tape. fresh material c...

Abstract Background Cotton stem trichomes and seed fibers are each single celled structures formed by protrusions of epidermal cells, were found sharing the overlapping molecular mechanism. Compared with fibers, cotton more easily observed, but mechanisms underlying their development still poorly understood. Results In this study, Gossypium hirsutum ( Gh ) G. barbadense Gb) to differ greatly in...

Barleria albostellata C.B. Clarke (grey barleria, Acanthaceae) is an indigenous shrub to South Africa and has been relatively understudied. This a valuable medicinal plant with wide spectrum of antibacterial anti-inflammatory activities. Detailed studies on the floral pollen morphology B. are rare. study was conducted observe flower grains using stereomicroscopy scanning electron microscopy (SE...

In this study, the main features of trichomes, nutlet, and pollen A. orientalis, which growing in four different provinces Turkey, were examined as detail results illustrated. orientalis carries both peltate capitate well non-glandular ones. However, subtypes glandular trichomes recognized. The shape nutlets is obovate, oblong-obovate nutlet surface sculpturing alveolate. grains euprolate (P/E ...

Orv'za gluniaepatula is a perennial wild rice species, endemic to tropical America, previously known as the Latin American race of Orrza rufipogon. In Costa Rica, it is found in the northern region of the country, mainly in the wetland of the Medio Queso River, Los Chiles, Alajuela. It is diploid, of AA type genome and because of its genetic relatedness to cultivated rice it is included in the ...

Miers, considered official botanical source plant Guduchi other two species such malabarica (Lam.) Hook. f. &Thomson and crispa (L.) & Thomson are a different parts India. it looks very similar morphological characters, micrometric differentiation ...

Large areas of cultivated land in China, Japan and Thailand have been contaminated with lead (Pb), zinc (Zn) and cadmium (Cd) to the extent that demonstrable effects on human health have been reported. The extent of contamination virtually prohibits either removal of soils or agricultural utilization. Phytoremediation, the use of plants to extract toxic metals from soils, is one of the only via...
