this study was aimed to study the ways of removing dormancy period and accelerating pre-sowing tuber germination to provide simple tools to apply by farmers. for this purpose, intact tubers, exposed tubers to released ethylene and sliced tubers were examined in respect to germination characters, bud length, starch, anthocyanin and chlorophyll contents and amylase activity. relative amount of an...

abstract the present research was done to evaluate proline, proteins and sugars of flower buds of pistachio trees during phonological stages. this study was conducted using a split-plot design with three replications considered time as main factor (5 stages) and cultivars (ahmad-aghaee, ouhadi, kaleh-ghochi and akbari) as secondary factor. the experiment was conducted at ferdowsi university of ...

primary bud necrosis (pbn) in grapevine is a physiological disorder that leads to death of fruitful buds and yield loss. the aim of this study was to determine the changes in soluble sugars and starch and their relationship to the incidence of the primary bud necrosis in askari grapevine. experiment was conducted in a vineyard that the vines were 15 years old, with a head system, vines spaced 2...

The transcription start site and DNA sequence elements required for the induction of Pax3 expression in differentiating P19 embryonal carcinoma cells have been localized. These elements consist of a promoter and additional elements located within 1.6 kbp 5' to the transcription start site. Sequence elements within this 1.6 kbp region are also sufficient to mediate the induction and dorsal restr...

Dormancy and subsequent regrowth of adventitious buds is a critical physiological process for many perennial plants. We have used the expression of hormone and cell cycle-responsive genes as markers to follow this process in leafy spurge (Euphorbia esula). In conjunction with earlier studies, we show that loss of mature leaves results in decreased sugar levels and increased gibberellin percepti...

New Guinea Impatiens (Impatiens hawkeri W. Bull) is an eye-popping landscaping plant of bright and colorful blooms. A highly efficient in vitro regeneration system via direct shoot organogenesis was established for the first time from hypocotyl with partial cotyledons Impatiens. Our results showed that explant sterilization method, basic medium type, AgNO3, sucrose growth regulators have signif...

BACKGROUND Previous studies have shown disparities between Black and Hispanic patients compared with other populations in response to asthma medications. OBJECTIVE The aim of this analysis was to assess the effect of budesonide/formoterol pressurized metered-dose inhaler (BUD/FM pMDI) and BUD on predefined criteria for asthma worsening, an asthma control metric generally aligned with definiti...

The most obvious phenotype of Ft/+ mice is a syndactyly of fore limbs characterised by a fusion of the tips of digits 1 to 4. The tempospatial expression of genes involved in limb development revealed that patterning of Ft/+ limb buds is not affected by the mutation. However, an upregulation of Bmp4 in the anterior-distal region of the limb bud at d12.0 of embryonic development is accompanied b...
