PREMISE OF THE STUDY Investigations of inflorescence architecture offer insight into the evolution of an astounding array of reproductive shoot systems in the angiosperms, as well as the potential to genetically manipulate these branching patterns to improve crop yield and enhance the aesthetics of horticultural species. The diversity of inflorescences in the economically important family Oleac...

Among the wild-type ecotypes of Arabidopsis thaliana whose shape of inflorescence is categorized as raceme, the ecotype Landsberg harboring the erecta (er) mutation shows a corymb-like inflorescence, namely, a compact inflorescence with a flattened arrangement of flower buds at the tip. The fact that the ER gene encodes a receptor-like protein kinase implies the presence of a signaling cascade ...

Inflorescence development is a key factor of plant productivity, as it determines flower number. Therefore, understanding the mechanisms that regulate inflorescence architecture is critical for reproductive success and crop yield. In this study, a new mutant, vegetative inflorescence (mc-vin), was isolated from the screening of a tomato (Solanum lycopersicum L.) T-DNA mutant collection. The mc-...

in order to evaluate the effect of harvest time on fruit weight, oil content and fruit bearing in the next year in some cultivars of olive (conservalea, amygdalolia, karidolia, koroneiki, arbequina, zard and rouwghani), an experiment was performed as a split plot in time based on crd (completely randomized design) with three replications at olive research station (tarrom–zanjan) during 2013 and...

Gibberellins (GAs) are plant hormones that play fundamental roles in plant growth and development. Gibberellin 2-oxidase (GA2ox) plays a direct role in determining the levels of bioactive GAs by catalyzing bioactive GAs or their immediate precursors to inactive forms. In this study, a GA2ox gene, designated JcGA2ox6, was isolated from Jatropha curcas. JcGA2ox6 is expressed in all tissues of adu...

seventeen iranian shallot genotypes from ashtian, arak, boroujerd, dashtearjan, doshmanziari, divandareh, khomein, khansar, sepidan, siakhdarengoon, sahne, kangavar, koohrang, koohmaresorkhi, nahavand, harsin and yasouj areas were evaluated for their morphological traits. corms were collected from the mentioned regions and planted based on a complete block design. quantitative and qualitative t...

The size and number of flowers displayed together on an inflorescence (floral display) influences pollinator attraction and pollen transfer and receipt, and is integral to plant reproductive success and fitness. Life history theory predicts that the evolution of floral display is constrained by trade-offs between the size and number of flowers and inflorescences. Indeed, a trade-off between flo...

BACKGROUND AND AIMS The inflorescence of grass species such as wheat, rice and maize consists of a unique reproductive structure called the spikelet, which is comprised of one, a few, or several florets (individual flowers). When reproductive growth is initiated, the inflorescence meristem differentiates a spikelet meristem as a lateral branch; the spikelet meristem then produces a floret meris...
