The Biology and Ecology of Rosa x hybrida (Rose)

Histological analyses of the fungal endophytes in Rosa hybrida.

Endophytes are fungi that cause asymptomatic infections in leaves and stems of healthy plants. This study evaluated the presence of endophytic fungi on leaves of Rosa hybrida collected in Bogota, (Colombia) using histological techniques and light microscopy. Histological preparations showed fungal mycelium with few cells in the vascular tissue. Colonization of mesophyll cells was not observed. ...

Sucrose is an early modulator of the key hormonal mechanisms controlling bud outgrowth in Rosa hybrida

Sugar has only recently been identified as a key player in triggering bud outgrowth, while hormonal control of bud outgrowth is already well established. To get a better understanding of sugar control, the present study investigated how sugar availability modulates the hormonal network during bud outgrowth in Rosa hybrida. Other plant models, for which mutants are available, were used when nece...

Gas Concentration in the Root Zone of Rosa hybrida L. Grown in Different Growing Media

The subject of this study was to get more information about the root zone, mainly the gas composition in growing media, which is used in hydroponic systems. Besides the plant growth parameters of roses, yield and nutrient uptake, the results of the gas concentrations in the root zone are presented. Gas sampling at 2 or 3 heights from root zone did function well, results ranged from 530 ppm to 1...

Interplay of sugar, light and gibberellins in expression of Rosa hybrida vacuolar invertase 1 regulation.

Our previous findings showed that the expression of the Rosa hybrida vacuolar invertase 1 gene (RhVI1) was tightly correlated with the ability of buds to grow out and was under sugar, gibberellin and light control. Here, we aimed to provide an insight into the mechanistic basis of this regulation. In situ hybridization showed that RhVI1 expression was localized in epidermal cells of young leave...
