calcium crystals are evident in many parts of anther. there is little literature about differentiationof crystal-containing cells and crystal formation during anther development. petunia hybrid grandifloraflower buds collected at different developmental stages were fixed and studied. the results revealed thatyoung anthers are tetrasporangiate and in each of the four corners, the primary parieta...

Floriculture crops can lose their aesthetic quality due to water deficit during postproduction. Calcium is a secondary messenger in plant stress signaling, and the treatment of calcium has been proposed alleviate damage by various abiotic stresses. The objective this research was evaluate application methods delay wilting under deficiency three species bedding plants: viola (Viola cornuta), imp...

This experiment was conducted to investigate the effect of paclobutrazol as an anti-gibberellin on some morpho-physiological characteristics of Petunia × grandiflora ‘Bravo Blue’, and determine the optimum concentration of paclobutrazol for drought resistance in this plant. The experiment was carried out as factorial based on completely randomized design with three replications in greenhouse. T...

Over the last decade, the yeast two-hybrid system has become the tool to use for the identification of protein-protein interactions and recently, even complete interactomes were elucidated by this method. Nevertheless, it is an artificial system that is sensitive to errors resulting in the identification of false-positive and false-negative interactions. In this study, plant MADS box transcript...

Expressions of the genes involved in the cytokinin (CK) phosphorelay signaling circuitry in petunia (Petunia hybrida Vilm.) were investigated with regard to the large-flowered trait induced by the semidominant Grandiflora (G) gene. We isolated three cDNAs encoding type-A response regulators (RRs, PhRR1-3) and one cDNA encoding CK receptor histidine protein kinase (PhHK). Expression levels of Ph...

A novel ATP synthase subunit 9 gene (atp9) was identified in the mitochondrial genome of a Petunia somatic hybrid line (13-133) which was produced from a fusion between Petunia lines 3688 and 3704. The novel gene was generated by intergenomic recombination between atp9 genes from the two parental plant lines. The entire atp9 coding region is represented on the recombinant gene. Comparison of ge...

The main objective of this research is to investigate the anti-biofilm and anti-bacterial activity of Sesbania grandiflora (S. grandiflora) against Staphylococcus aureus. S. grandiflora extract were prepared and analyzed with UV -Vis spectroscopy, Fourier transform infrared spectroscopy, Dynamic light scattering. Biofilm forming pathogens were identified by congo-red assay. Quantification of Ex...

Floral scent has been extensively investigated in plants of the South American genus Petunia. Flowers of Petunia integrifolia emit mostly benzaldehyde, while flowers of Petunia axillaris subsp. axillaris emit a mixture of volatile benzenoid and phenylpropanoid compounds that include isoeugenol and eugenol. Flowers of the artificial hybrid Petunia hybrida, a cross between P. integrifolia and P. ...

BACKGROUND Chonemorpha grandiflora (Syn. Chonemorpha fragrans (Apocynaceae) is an endangered medicinal plant. It is used in different preparations, such as sudarsanasavam and kumaryasavam used in Kerala Ayurvedic system. C. grandiflora is used for the treatment of fever and stomach disorders. Phytochemical investigations have revealed the presence of steroidal alkaloids, such as chonemorphine a...
