Green medicine, or pharmaceuticals made from plants, has gained widespread interest since they are thought to be more trustworthy and safe than expensive synthetic drugs with side effects. Miliusa species include Saccopetalum tomentosum (S. tomentosum). Plants of S. abundant in tropical subtropical areas, particularly mainland Asia. In examining phytochemical pharmacological features, ten were ...

The relationship between sucrose (Suc) and ascorbate (AA) metabolism was investigated in harvested broccoli (Brassica oleracea L. var. italica) florets. Decreases in both Suc and AA content were observed in broccoli florets 48 h after all the leaves were excised, but none were observed when the plants were kept intact or with leaves attached in a room at 20 degrees C. In harvested broccoli plan...

Background: Salinity is a major environmental limiting factor, which affect agricultural production. The two Manilkara seedlings (M. roxburghiana and M. zapota) with high economic importance, could not adapt well to higher soil salinity and little is known about their proteomic mechanisms. Objectives: The mechanisms responsible ...

Mutations in the AGAMOUS (AG) gene of Arabidopsis thaliana result in the conversion of reproductive organs, stamens and carpels, into perianth organs, sepals and petals. We have isolated and characterized the putative AG gene from Nicotiana tabacum, NAG1, whose deduced protein product shares 73% identical amino acid residues with the Arabidopsis AG gene product. RNA tissue in situ hybridization...

Ethylene is required for climacteric fruit ripening. Inhibition of ethylene biosynthesis genes, 1-aminocyclopropane-1-carboxylate (ACC) synthase and ACC oxidase, prevents or delays ripening, but it is not known how these genes are modulated during normal development. LeHB-1, a previously uncharacterized tomato homeobox protein, was shown by gel retardation assay to interact with the promoter of...

Perianth development is specifically disrupted in mutants of the PETAL LOSS (PTL) gene, particularly petal initiation and orientation. We have cloned PTL and show that it encodes a plant-specific trihelix transcription factor, one of a family previously known only as regulators of light-controlled genes. PTL transcripts were detected in the early-developing flower, in four zones between the ini...

background: transient and stable transformation of host plants are the common techniques to produce transgenic plants. however, the main drawback of stable transformation is the fact that it takes quite a long time to produce a transgenic line. while, transient gene expression is a quick method to produce recombinant proteins in plants.  objective: the main goal of the present study was to eval...

The research was aimed tostudy themorphological and anatomical characteristics as well habitatand geographical distributionof speciesPeltariaangustifolia DC., This study indicated that the plant specimens are perennial glabrous herbs, distinguished by presence of distinct basal cauline leaves, simple corymb inflorescence. Flowers perianth consists four obovate sepals, spathulate petals, with he...

The role of lipoxygenase (lox) in senescence of Alstroemeria peruviana flowers was investigated using a combination of in vitro assays and chemical profiling of the lipid oxidation products generated. Phospholipids and galactolipids were extensively degraded during senescence in both sepals and petals and the ratio of saturated/unsaturated fatty acids increased. Lox protein levels and enzymatic...
