investigation into total phenolics and their spectrum in the buds and corms of saffron crocus and a study of polyphenol oxidase changes in the apical bud during different stages of growth and development showed that changes in the growth and development of the apical bud may be related to changes in the composition of phenolics in the corm. a sudden intense change in content and kind of phenoli...

Indole-3-acetic acid stimulates ethylene production in the nodal region of pea stems, and the gas inhibits bud growth. At all concentrations of IAA there is a close correlation between the intensity and duration of ethylene production and the bud inhibition which results. Kinetin reverses the inhibitory actions of ethylene and IAA on bud growth. It is concluded that auxins suppress bud developm...

gladiolus is one of the flowers that used on cut flower and garden plants. an experiment was conducted to study the effects of chemical treatments on the vase life of gladiolus cut flower cv. ‘rose supreme’ with ten chemical treatment using complete randomize design with 3 replications. gladiolus cut flower was harvested when the 2-3 lowest bud had start showing color then cut flower were treat...

Two experiments were conducted to characterize changes associated with ontogenetic aging in coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and to identify possible maturation "markers" for this species. In the first experiment (Experiment 1), scions of ages 1, 4 and 9 years were collected from four seed zones in field progeny tests and grafted onto 1-year-old rootstocks. In Experime...

Sugar has only recently been identified as a key player in triggering bud outgrowth, while hormonal control of bud outgrowth is already well established. To get a better understanding of sugar control, the present study investigated how sugar availability modulates the hormonal network during bud outgrowth in Rosa hybrida. Other plant models, for which mutants are available, were used when nece...

BACKGROUND To function in diverse cellular processes, the dynamic behavior of microtubules (MTs) must be differentially regulated within the cell. In budding yeast, the spindle position checkpoint (SPOC) inhibits mitotic exit in response to mispositioned spindles. To maintain SPOC-mediated anaphase arrest, astral MTs must maintain persistent interactions with and/or extend through the bud neck....

BACKGROUND Morbidity due to Buruli ulcer disease (BUD), a cutaneous infection caused by Mycobacterium ulcerans, has been increasingly recognized in rural West Africa. The source and mode of transmission remain unknown. METHODS To identify BUD risk factors, we conducted a case-control study in 3 BUD-endemic districts in Ghana. We enrolled case patients with clinically diagnosed BUD and obtaine...

The fine structure of bud formation of Metschnikowia krissii was studied by means of ultramicrotomy and transmission electron microscopy. Bud protrusion and development were observed by scanning electron microscopy. Bud formation in this yeast takes place by an extension of a small localized area of the existing parent wall. The parent cell and its bud are initially separated by the plasmalemma...

In the budding yeast Saccharomyces cerevisiae, a prospective mother normally commences the formation of a daughter (the bud) only in the G(1) phase of the cell division cycle. This suggests a strict temporal regulation of the processes that initiate the formation of a new bud. Using cortical localization of bud site components Spa2 and Bni1 as an indicator of bud site assembly, we show that cel...

n page 897, Luedeke et al. show that, like the plasma membrane, the ER can be compartmentalized into distinct membrane domains. In budding yeast, this separation restricts the diffusion of ER membrane proteins between the bud and the mother cell. The mRNAs of many bud-specific membrane proteins are actively transported into the bud. To keep these mRNAs and proteins in the bud, they must be kept...
