Polyploidy is a pivotal process in plant evolution as it increase gene redundancy and morphological intricacy but due to the complexity of polysomic inheritance we have only few genetic maps of autopolyploid organisms. A robust mapping framework is particularly important in polyploid crop species, rose included (2n = 4x = 28), where the objective is to study multiallelic interactions that contr...

BACKGROUND Conventional cut-offs for hypertension are arbitrary, and vascular complications can occur below these values, particularly in diabetes. AIM To evaluate systolic blood pressure (SBP) distribution in diabetes and control populations, comparing hypertension prevalence using either conventional cut-offs (140 and 160 mmHg) or age-adjusted centile (75(th) and 90(th)) cut-offs derived fr...

Effects of exogenously applied methyl jasmonate (MeJA) and sucrose on vase life and non-structural carbohydrate concentration in petals and leaves of cut ‘First Red’ roses were investigated. Roses were placed in sealed plastic containers and received MeJA vapour treatment (0.1 μL MeJA L-1) for 24 h at 20°C. Flowers were then placed in individual bottles containing 0 or 2% (v/v) sucrose solution...

The most popular fragrant cut rose cultivar in Japan is ‘Yves Piaget’, but its petals often become malformed after harvest. These flowers, referred to as “incurved flowers”, are characterized by curving toward the adaxial side which prevents normal flowering and significantly decreases flower quality. It has been reported that jasmonic acid (JA) affects petal growth, could suppress emergence of...
