Submit Manuscript | http://medcraveonline.com main component of flower color is anthocyanin, a type of flavonoid [1]. Numerous genes involved in anthocyanin biosynthesis have been analyzed in various plants, and their biosynthesis pathways determined [2,3]. In addition to anthocyanins, flavonols and organic acids also play a role in flower color as ‘co-pigments’ [4]. Fragrant cyclamen cultivars...

Description A perennial herb with a subterranean, digitately branched rhizome producing stems up to 1.50 m in height with linear lanceolate sheating leaves (5-30 cm long and 8-20 mm wide) that are alternate, smooth and pale green. Flower stems shorter than leaf stems and bearing a few flowers, each surrounded by a thin bract and situated in axils of large greenish yellow obtuse bracts, which ar...

In dioecious plants, females typically invest more biomass in reproduction than males and consequently experience stronger life-history trade-offs. Sexual dimorphism in life history runs counter to this pattern in Silene latifolia: females acquire less carbon and invest more biomass in reproduction, but males pay a higher cost of reproduction. The species is sexually dimorphic for many traits, ...

In tropical dry forests most plants are deciduous during the dry season and flush leaves with the onset of the rains. In Costa Rica, the only species displaying the opposite pattern is Bonellia nervosa. To determine if seasonal changes in light availability are associated with the leaf and reproductive phenology of this species, we monitored leaf production, survival, and life span, as well as ...

We isolated a novel pungent principle from the flower buds of myoga. Based on an interpretation of the HR-MS, EI-MS, IR, UV, and NMR data, this compound was (8betaH)-14,17-cyclolabda-12,14(17)-diene-15,16-dial (mioganal, 1). We determined the threshold value of mioganal to be 5.6x10(-5) g/ml, which is about eight times greater than that of 8beta(17)-epoxy-12(E)labdene-15,16-dial (miogadial), th...

A cDNA clone, MdMADS1, containing MADS domain was isolated from the Fuji apple. The gene was expressed in all floral organs and young fruits but not in leaves. The expression was higher at the early stages of flower and fruit developments, suggesting that MdMADS1 plays a major role in the initiation of reproductive organ developments.

Eukaryote-associated microbiomes interact with their hosts in multiple manners, thereby affecting the hosts' phenotype, physical condition and behaviour. In plants, bacteria have numerous functions, with variable net effects, both in natural and agricultural systems. However, information about the composition and diversity of the bacterial communities associated with different aboveground plant...

To investigate the effects of nutrient-solution concentrations of potassium (K) and calcium (Ca), as well as different ratios of K/Ca, on growth and flowering of lisianthus (Eustoma grandiflorum) under soilless culture conditions, a factorial experiment was conducted with two factors including two K levels (300 and 400 mg/L) and three Ca levels (80, 100 and 160 mg/L). Results showed that K= 400...
