The distribution of the flavanones naringin and neohesperidin has been analyzed during the development of the leaves, flower buds, and fruits of Citrus aurantium. These flavonoids are at maximum concentration in the organs studied during the logarithmic phase of growth, gradually decreasing until the organs reach maximum development. However, this decrease in the naringin and neohesperidin conc...

Introduction and objective: Otitis externa, commonly called ear disease, is characterized by inflammation of the external ear canal. The aim of this study was to evaluate the antimicrobial potential of Cassia fistula flowers, leaves and bark extracts against Staphylococcus aureus, Proteus mirabilis, Escherchia coli, Pseudomonas aeruginosa, Acinetobacter sp., and Candida albicans, pathogens caus...

Floral longevity (FL) determines the balance between pollination success and flower maintenance. While a longer floral duration enhances the ability of plants to attract pollinators, it can be detrimental if it negatively affects overall plant fitness. Longer-lived leaves display a positive correlation with their dry mass per unit area, which influences leaf construction costs and physiological...

various plant organ segments including segments from roots (root tip, and root collar), stems, leaves, and also seeds of several hyoscyamus species (i.e. h. pusillus, h. arachnoideus, annual and biennial h. niger from two distinct geographical regions) were cultured on ms media with various growth regulator combinations, to assess the ability of flower production. statistical assessments showed...

Two cDNAs (PhERS1 and PhETR2) encoding ethylene receptor homologues were cloned and characterized from petunia. Genomic Southern blot analysis revealed that small families of PhERS1-related and PhETR2-related genes exist in petunia. PhERS1 and PhETR2 are constitutively expressed in stem, flower bud, flower, and roots, with a very low level in leaves. High levels of both PhERS1 and PhETR2 transc...

Alloplasmic lines of Brassica napus with rearranged Arabidopsis thaliana mitochondrial DNA are male sterile and vegetatively altered compared with B. napus cv. Hanna. The CMS lines contain pure nuclear and plastid genomes from B. napus. Cross-sections of leaves revealed elevated starch accumulation and a higher number of chloroplasts per cell area in CMS plants compared with B. napus. The incre...

Rafflesia is a biologically enigmatic species that is very rare in occurrence and possesses an extraordinary morphology. This parasitic plant produces a gigantic flower up to one metre in diameter with no leaves, stem or roots. However, little is known about the floral biology of this species especially at the molecular level. In an effort to address this issue, we have generated and characteri...

Liriope platyphylla Wang et Tang (L. platyphylla) is named Liriope muscari with Binomial name and called big blue lilyturf, lilyturf, border grass and monkey grass with common name [1]. It is widely used as one of the 50 fundamental herbs in traditional Oriental medicine; the species is one member of low, herbaceous flowing plats, which grows commonly in the shady forests of East Asia including...

Such aposematic signaling has been hypothesized to be widespread in plants, however, it has up...
