BACKGROUND AND AIMS Rheum, a highly diversified genus with about 60 species, is mainly confined to the mountainous and desert regions of the Qinghai-Tibetan plateau and adjacent areas. This genus represents a good example of the extensive diversification of the temperate genera in the Qinghai-Tibetan plateau, in which the forces to drive diversification remain unknown. To date, the infrageneric...

Cephalotes minutus (Fabricius, 1804) Myrmicinae Sebastiani et al. 433 (HARA) Containing approximately 75 genera and 1.300 species, Malpighiaceae is one of the most diverse families of tropical and subtropical lianas and shrubs worldwide, which is predominantly distributed within the neotropics (Anderson, 2013). In Brazil, Malpighiaceae is represented by 44 genera and approximately 561 species d...

Abstract— The Lathberry Clade includes seven species of Eugenia sect. Umbellatae (Myrtaceae) distributed from Puerto Rico through the Lesser Antilles. Members are trees and shrubs distinguished other Antillean by a combination dull twigs, glabrous leaves with raised midvein, glomerate or fasciculate inflorescences predominantly borne below on old wood, closely spaced ascending inflorescence bra...

Fruit has very attractive colour and mellow mouth melting pulp with black seed embedded in along tremendous nutritive property which attract growers from different part India to cultivate this crop originated Mexico Central & South America. It a long day plant beautiful night blooming flower that nick named as “Noble Woman”...

This paper describes the physical and tensile properties of corn bracts during a whole harvest period by using two cultivars, aiming to realize efficient peeling with minimum energy performance decrease incidence ear damage. The value range change rule were obtained combining mechanical experiments numerical statistics. Meanwhile, mathematical models established for depending on bract moisture ...


 Pinalia elata is an attractive endemic species of Peninsular Malaysia, known from only six localities within the Titiwangsa mountain range where it confined to montane vegetation. However, four these are now threatened by anthropogenic factors, raising concerns about ongoing survival this in wild. Despite efforts understand conservation status Malaysian orchid species, there remains much...

Dianthus berkayii belongs to sect. Fimbriati was described and illustrated as a new species from Erzincan Province in Eastern Anatolia, Turkey. In the current study morphological, palynological, molecular characters were compared discussed with its closely related species. The is similar D. crinitus fimbriate corolla, linear, acuminate, ± rigid leaves. Also vanensis rigid, curved divaricate But...

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...

Fleshy structures associated with the ovule/seed arose independently several times during gymnosperm evolution. are linked to protection and dispersal, present in all four lineages of extant gymnosperms. The ontogenetic origin fleshy could be different, spans from ovule funiculus Taxus baccata aril, integument Ginkgo biloba, modified bracts as case Ephedra species. This variability ontogeny is ...

Poinsettia is an economically important ornamental potted plant in which certain bract colour variants are often obtained by mutation breeding. Previously, poinsettia, we identified Bract1, a GST gene involved the sequestration and transport of anthocyanins to vacuole. This carries short, highly mutable 4-bp repeat its coding region. Loss one unit leads loss function for homozygous mutants, ant...
