BACKGROUND AND AIMS In andromonoecious taxa with separate floral types along the inflorescence, architectural or plastic effects can simulate floral sexual dimorphism. Both the primary and secondary sexual characteristics of the cyathia of the protogynous andromonoecious species Euphorbia nicaeensis were analysed according to their sex and arrangement on the inflorescence. METHODS The product...

The shapes of flowers and their organization into branching systems, called inflorescences, dictate much of plant diversity. Recent studies have identified key regulators in this diversity, revealing that the inflorescence architecture of Solanaceous species depends on sequential and temporal expression of the WUSCHEL-RELATED HOMEOBOX (WOX) gene EVERGREEN (EVG)/ COMPOUND INFLORESCENCE (S) and t...

Tomato is a major crop plant and several mutants have been selected for breeding but also for isolating important genes that regulate flowering and sympodial growth. Besides, current research in developmental biology aims at revealing mechanisms that account for diversity in inflorescence architectures. We therefore found timely to review the current knowledge of the genetic control of flowerin...

ABSTRACT In the last years, jambu has become popular and greatly appreciated, due to its remarkable taste. Thus, hydroponically cultivated is promising, since it achieves better yield production quality. The aim of this study was evaluate effect ionic concentration in nutrient solution on growth, productivity gas exchange jambu. experimental design completely randomized, with five treatments fo...

A survey was carried out in two states, six locations of south east Nigeria during the normal flowering period for three (3) consecutive years to evaluate intraspecific variations phenology African pear flowering. The different types species growing forest, distant and nearby farms, including homesteads were used. 60 trees 180 flowered branches sampled survey. Parameters collected include time ...

Cytokinins and gibberellins (GAs) play antagonistic roles in regulating reproductive meristem activity. Cytokinins have positive effects on meristem activity and maintenance. During inflorescence meristem development, cytokinin biosynthesis is activated via a KNOX-mediated pathway. Increased cytokinin activity leads to higher grain number, whereas GAs negatively affect meristem activity. The GA...

Yield is one of the most important yet complex crop traits. To improve our understanding of the genetic basis of yield establishment, and to identify candidate genes responsible for yield improvement in Brassica napus, we performed genome-wide association studies (GWAS) for seven yield-determining traits [main inflorescence pod number (MIPN), branch pod number (BPN), pod number per plant (PNP),...
