Isoprenoids constitute the largest class of plant natural products and have diverse biological functions including in plant growth and development. In potato (Solanum tuberosum), the regulatory mechanism underlying the biosynthesis of isoprenoids through the mevalonate pathway is unclear. We

Fluctuations in day length determine the time to flower in many plants and in potato are critical to promote differentiation of tubers. Day length is perceived in the leaves and under inductive conditions these synthesize a systemic signal that is transported to the underground stolons to induce

Sucrose (Suc) transporters belong to a large gene family. The physiological role of SUT1 proteins has been intensively investigated in higher plants, whereas that of SUT4 proteins is so far unknown. All three known Suc transporters from potato (Solanum tuberosum), SUT1, SUT2, and SUT4, are

In 1992 symptoms consisting of twig dieback, canker-like deformities, and often, mortality of all sizes of container-grown flowering dogwood trees (Cornus florida L.) was frequently observed in northern Florida where nursery production of dogwood is concentrated. Twigs, branches, growing points, and

Theobroxide, a novel active compound isolated from a fungus, has been reported previously to induce potato tuberization and flower bud formation in Pharbitis nil under non-inductive long-day conditions. Up to date, the action mechanism of theobroxide on flower-bud induction of P. nil, however, is

Viroid infection often leads to early flowering in the host plant. This report describes the targeting of the FRIGIDA-like protein 3 (FRL3) mRNA in tomato plants by a small RNA derived from the conserved left terminal region of the potato spindle tuber viroid (PSTVd). This targeting leads to the

Asexual and sexual reproduction occur jointly in many angiosperms. Stolons (elongated stems) are used for asexual reproduction in the crop species potato (Solanum tuberosum) and strawberry (Fragaria spp), where they produce tubers and clonal plants, respectively. In strawberry, stolon production is

Plant growth and development, particularly the induction of flowering, are tightly controlled by key regulators in response to endogenous and environmental cues. The FLOWERING LOCUS T (FT)/TERMINAL FLOWER 1 (TFL1) family of phosphatidylethanolamine-binding protein (PEBP) genes is central to plant

The phosphatidyl ethanolamine-binding proteins (PEBPs) function primarily in regulating flowering in plants. Here, we report a genome-wide identification of PEBPs and functional characterization of a novel FLOWERING LOCUS T homolog (NtFT5) in tobacco, Nicotiana tabacum. Seven new PEBPs were

A partial cDNA clone has been isolated which represents a gene that is induced in potato (Solanum tuberosum L.) leaves upon tuber initiation. The gene is also present in tobacco (Nicotiana tobacum L.) where it is induced upon flowering, and in tomato (Lycopericon esculentum, L.) where it is induced

Virus-induced flowering (VIF) uses virus vectors to express Flowering Locus T (FT) to induce flowering in plants. This approach has recently attracted wide interest for its practical applications in accelerating breeding in crops and woody fruit trees. However, the insight into VIF and its potential

Flowering dogwood (Cornus florida L., Cornaceae), is a small deciduous tree whose showy inflorescences, clusters of bright red fruits and red and purple leaves in autumn, make it a much appreciated ornamental. In June of 2008, severe outbreaks of a previously unknown blight were observed in several

The Arabidopsis flowering locus T (FT) gene encodes the mobile florigen essential for floral induction. While movement of the FT protein has been shown to occur within plants, systemic spread of FT mRNA remains to be unequivocally demonstrated. Utilizing novel RNA mobility assay vectors based on two
