b-galactosidases have been detected in a wide range of plants and are characterized by their ability to hydrolyse terminal non-reducing b-D-galactosyl residues from b-D-galactosides. These enzymes have been detected in a wide range of plant organs and tissues. In a search for differentially expressed genes during the abscission process in citrus, sequences encoding b-galactosidase were identifi...

Despite problems of low fruit set, small fruit size and alternate bearing, the Hass cultivar dominates commercial avocado production worldwide. To increase yield and fruit size, gibberellic acid (GA3) (25 mg L−1) was applied at different stages of ‘Hass’ avocado tree phenology: (i) mid–late April (flower abscission), end of June–beginning of July (fruit abscission and beginning of the exponenti...

field trials with dizigotheeca elegantissima were conducted at the experimental farm of faculty of agriculture, azad university  jiroft  in growth seasons of 2012 year. the aim of this work was to study the effect of foliar application of gibberellic acid [ga3] and benzyladenine [ba] at 0, 50, 100 and 150 mgl-1 on the vegetative growth and photosynthetic pigments of d. elegantissima plants. mos...

Auxin, a vital plant hormone, regulates a variety of physiological and developmental processes. It is involved in fruit abscission through transcriptional regulation of many auxin-related genes, including early auxin responsive genes (i.e., auxin/indole-3-acetic acid (AUX/IAA), Gretchen Hagen3 (GH3) and small auxin upregulated (SAUR)) and auxin response factors (ARF), which have been well chara...

Wood vinegar is a substance, derived from cooling black carbon fire, which could be used instead of chemical materials in the agriculture industry as an organic compound. In order to study the effectiveness of pine wood vinegar on physiological and photosynthesis traits of cucumber, two experiments were conducted based on a completely randomized design with six treatments including 0, 1250, 200...

The effects of 1-methylcyclopropene (1-MCP) and naphthaleneacetic acid (NAA) on fruit set and the expression of genes related to ethylene biosynthesis and perception and cell wall degradation in apple (Malus ·domestica Borkh.) were studied when applied during the normal chemical thinning period. 1-MCP at 209 mg L had a small negative effect or no effect on the final fruit set, depending on the ...

MADS-domain proteins are important transcription factors involved in many biological processes of plants. In our study, a tomato MADS-box gene, SlFYFL, was isolated. SlFYFL is expressed in all tissues of tomato and significantly higher in mature leave, fruit of different stages, AZ (abscission zone) and sepal. Delayed leaf senescence and fruit ripening, increased storability and longer sepals w...
