African marigold, being tall enough and producing large flowers suitable for preparing garlands, is the most cultivated cultivar of marigold in Nepal. Besides, pinching other improved cultural techniques, a number chemicals, hormones phyto-hormones are tested found to impart varying response marigold. This review has its importance standardizing type concentration plant growth regulators Online...

Despite the bewildering ability of higher plants to change their development with respect to the environment, there appear to be only a few hormones that function to organize growth and development. With the recent identification of three plant hormone receptors, the molecular identities of all the major plant receptors are now known. Some plant hormones such as cytokinins, ethylene, and brassi...

Recently published evidence suggests that hyperinsulinemia, insulin-like growth factors, and abnormal glucose intolerance may promote mammary carcinogenesis (1-6) and that women with type 2 diabetes are at increased risk for postmenopausal breast cancer (1, 3). Insulin and insulin-like growth factors are major determinants of proliferation and apoptosis (5, 6). Steroid hormones are also importa...

The objective of this study was to investigate the effects of indole-3-acetic acid (IAA) and kinetin (KIN) on Mucor indicus growth, cell wall composition, and ethanol production. A semi-synthetic medium, supplemented with 0-5 mg/L hormones, was used for the cultivations (at 32 °C for 48 h). By addition of 1 mg/L of each hormone, the biomass and ethanol yields were increased and decreased, respe...

Temperate woody plants suffer environmental stresses caused by seasonal changes. Seasonal changes affect tree cambium activity, resulting in the annual periodicity of growth. In present study, we provide a model for plant hormone coordination monolignol biosynthesis to cope with poplar species. First, 27 core lignin-related genes were identified Populus tomentosa, and co-expression lignifying t...

In the last two decades it has become clear that hormones and gene mutations in endocrine signaling pathways can exert major effects on lifespan and related life history traits in worms, flies, mice, and other organisms. While most of this research has focused on insulin/insulin-like growth factor-1 signaling, a peptide hormone pathway, recent work has shown that also lipophilic hormones play a...

Cisplatin is an effective anti-cancer drug which has been successfully utilized in the treatment of many cancer types. However, cisplatin has shown only limited efficacy in the majority of breast tumors, and is not generally included as a monotherapy in this disease. The potential role of hormones in chemoresistance in breast cancer has received little attention. This review focuses on two clas...

Genetic and molecular approaches have enabled the identification of regulatory genes critically involved in determining cell types in the pituitary gland and/or in the hypothalamus. Here we report that Otx1, a homeobox-containing gene of the Otx gene family, is postnatally transcribed and translated in the pituitary gland. Cell culture experiments indicate that Otx1 may activate transcription o...

BACKGROUND Bryophytes represent a very diverse group of non-vascular plants such as mosses, liverworts and hornworts and the oldest extant lineage of land plants. Determination of endogenous phytohormone profiles in bryophytes can provide substantial information about early land plant evolution. In this study, we screened thirty bryophyte species including six liverworts and twenty-four mosses ...

Twenty-one Simmental crossbred bulls (311 -+ 11 kg, 9 mo of age) were used to determine the effect of feeding 10, 12 or 14% CP on concentrations of hormones in blood and the relationship of these hormones to composition of gain. Six bulls were slaughtered on d 0 to provide an estimate of initial carcass composition (9-11 rib section). Remaining bulls were assigned to dietary treatments. Blood s...
