Regulation of Development of the Storage Root of Sugarbeet
… cambial activity in sugarbeet, the role of the gibberellins in cell division and expansion has been studied. Analyses of endogenous gibberellin-like substances of sugarbeet and mangold shoots and storage roots through the vegetative developmental period have revealed that the activity of the …

Evaluation of Methods for Control of Vegetation in Utility Corridors
… (chemicals that suppress the production of gibberellins, the plant hormones that control stem elongation). Choosing the appropriate control method is a decision that vegetation program managers should take based on many factors, like costs, environmental impacts, existing agreements with the …

The Control of Spore Germination in Anemia Phyllitidis (L.) Swartz and Other Ferns
… In one family of ferns, the Schizaeaceae, the gibberellins overcome this light requirement and induce dark-germination. Fern gametophytes produce antheridium-inducing substances. The Anemia substance, antheridogen-B, is demonstrated to induce germination in two genera of the Schizaeaceae, …

Functional genomics through metabolite profiling and gene expression analysis in Arabidopsis thaliana
… acid, indole-3-acetic acid, salicylic acid, gibberellins, and other plant constituents into methyl esters, thereby regulating the biological activity of these molecules and, consequently, myriad important physiological processes. Our research aims to decipher the function of proteins …

Investigating the evolution of cytochromes P450 involved in GA biosynthesis
… no labdane-related diterpenoids other than gibberellins, whereas rice produces a wide range of such natural products as antibiotic phytoalexins or allelochemicals. While rice contains several kaurene oxidase homologs, only OsKO2 (CYP701A6) is required for gibberellin biosynthesis. Here, we …

Evaluation of Masculinization Treatments to Produce Feminized Hemp Seed (Cannabis sativa L.)
… the inhibition of ethylene and/or addition of gibberellins before flower initiation in female plants. The hemp industry uses silver thiosulfate (STS) to masculinize hemp, but spraying silver poses environmental concerns. This study compared STS to three other ethylene-inhibiting agents: …

Respuestas fúngicas a señales ambientales: Funciones de las proteínas CarO, OpsA, CutA y AcyA en Fusarium fujikuroi
… of biotechnological interest, such as gibberellins, bikaverin, and carotenoids. Production of these metabolites is regulated by nitrogen availability and, in a specific manner, by other environmental signals, such as light in the case of the carotenoid pathway. A complex regulatory …

Dormancy and sprout control in root and tuber crops
… Consistent with sprout stimulation by gibberellins (GAs) in potato, 10 mM GA3 enhanced sprout length and number in sweetpotato roots and sprout growth was decreased by 20 ml/L piccolo (GA synthesis inhibitor). Continuous application of 10 ppm ethylene or greater prevented sprouting in …

Phytohormones and the Culture of Agaricus bisporus (Lange) Pilat
… of the three groups of phytohormones (auxins, gibberellins and cytokinins). The fluctuation in levels of phytohormones in compost and casing soil were related to fluctuations in the population of bacteria and fungi. Phytohormones play a role in regulating the interaction between A. bisporus and …

The molecular basis for the initiation of fruit development and parthenocarpy
… to pollinated pistils. Dependencies on gibberellins during silique development were examined in mutants defective for gibberellin biosynthesis (ga1, ga4-1, ga5-1) or perception (spy-4, gai-1). Although exogenous GAs are effective at inducing parthenocarpy, mutant studies concluded that …

Seed dormancy and germination niches of Mediterranean species along an altitudinal gradient in Sardinia
… and dry after ripening) and hormones (gibberellins) on the thermal requirements for seed dormancy release and germination of the target taxa was assessed. To study and monitor the annual trend of local soil temperatures, close to the study species, 24 data-loggers were buried along the …

Germination niche of Sardinian endemic species in mountain riparian deciduous forests
… in part, by the plant hormones abscisic acid and gibberellins. Dormancy can be broken by some environmental stimuli, such as a cold and/or warm stratification and gibberellic acid (GA) treatment. As dormancy is present throughout the higher plants in all major climatic regions, adaptation has …

GENETIC DISSECTION OF PINE1 CONTROLLED STEM ELONGATION AND NEW INSIGHTS INTO LONG DAY FLOWERING IN ORYZA SATIVA
… Rice pine1 mutants are highly responsive to gibberellins (GA) as their internodes rapidly elongate proportionally to the exogenous GA concentration, contrary to WT stems whose growth is unaffected. To understand how PINE1 may be involved in the GA signalling pathway, we have generated single …
