Systemins and their hydroxyproline-rich glycopeptide systemin (ppHS) subfamily members are known to mediate antiherbivore defenses in some solanaceous taxa but not others; functions other than in defense remain largely unexplored. Nicotiana attenuata's ppHS is known not to function in herbivore defense. NappHS transcripts are abundant in flowers, particularly in pistils, and when two N. attenua...

in this research, during three consecutive years (2010-2012), a series of diallel crossing was performed among wild type barberry genotypes and iranian seedless barberry. setting of seed and fruit in the crossing have been studied and then seedling survival were evaluated in several cultural systems. results showed significant effects of pollen sources on setting of fruits, seed and seeded frui...

Fruit set involves the developmental transition of an unfertilized quiescent ovary in the pistil into a fruit. While fruit set is known to involve the activation of signals (including various plant hormones) in the ovary, many biological aspects of this process remain elusive. To further expand our understanding of this process, we identified genes that are specifically expressed in tomato (Sol...

The old calendar of pollens did not reflect current pollen distribution and concentrations that can be influenced by changes of weather and environment of each region in South Korea. A new pollen calendar of allergenic pollens was made based on the data on pollen concentrations obtained in eight regions nationwide between 1997 and 2009. The distribution of pollen was assessed every day at 8 are...

In this study, the effect of storage at different times and temperatures on in vitro olive pollen germination was investigated. Pollens Gemlik Domat cultivars GE119 GK138 genotypes were stored +4 °C, -20 -80 °C for 7, 35, 200, 365 days, respectively. status determined by petri agar method, choosing most suitable nutrient medium each olive. The media Gemlik, Domat, GE119, pollens 50 ml water + 1...

The differences between stylar protein of the Japanese pear (Pyrus pyrifolia (Burm.f.)) cultivars ‘Kosui’ (SS) and ‘Kikusui’ (SS) were compared by two-dimensional difference gel electrophoresis (2-D DIGE), and were labelled and visualized with different fluorescent dyes (IC3-OSu, IC5-OSu) on a single 2-D gel. The individual different expressed proteins spots were subjected to identification. Th...
