THE GENETIC RESOURCES AND THEIR UTILIZATION OF PYRUS PYRIFOLIA IN CHINA
Acta Horticulturae, 2002The collection, conservation, and assessment of genetic resources of Pyrus pyrifolia, as well as the utilization in the bud sport selection and the cross breeding of those in China are reviewed based mainly on the present data from Chinese literature.

The role of Ca2+ and Ca2+ channels in the gametophytic self-incompatibility of Pyrus pyrifolia
Cell Calcium, 2016In S-RNase-based self-incompatibility, S-RNase was previously thought to function as a selective RNase that inhibits pollen whose S-haplotype matches that in the pistil. In this study, we showed that S-RNase has a distinct effect on the regulation of Ca2+-permeable channel activity in the apical pollen tube in Pyrus pyrifolia.

cAMP activates hyperpolarization-activated Ca2+ channels in the pollen of Pyrus pyrifolia
Plant Cell Reports, 2011Many signal-transduction processes in plant cells have been suggested to be triggered by signal-induced opening of calcium ion (Ca(2+)) channels in the plasma membrane. Cyclic nucleotides have been proposed to lead to an increase in cytosolic free Ca(2+) in pollen.

Shoot regeneration from cultured leaves of Japanese pear (Pyrus pyrifolia)
Plant Cell, Tissue and Organ Culture, 1998Several experiments were conducted to investigate in vitro regeneration of adventious shoots from cultured leaves of Japanese pear (Pyrus pyrifolia). A protocol was developed and regeneration achieved from six cultivars. Leaves harvested from shoot cultures which had been preconditioned on B5 medium with 5 μM thidiazuron plus 0.25 μM gibberellic acid ...

Fast loading ester fluorescent Ca2+ and pH indicators into pollen of Pyrus pyrifolia
Journal of Plant Research, 2011Loading of Ca(2+)-sensitive fluorescent probes into plant cells is an essential step to measure activities of free Ca(2+) ions in cytoplasm with a fluorescent imaging technique. Fluo-3 is one of the most suitable Ca(2+) indicators for CLSM. We loaded pollen with fluo-3/AM at three different temperatures. Fluo-3/AM was successfully loaded into pollen at

[Region optimization of SSC model for Pyrus pyrifolia by genetic algorithm].
Guang pu xue yu guang pu fen xi = Guang pu, 2010Genetic algorithm is widely used in NIRS data optimization, which is not limited by searching space. The region selecting by genetic algorithms (R-SGA)was applied in building calibration model of soluble solid content (SSC)of Pyrus pyrifolia, and the number of variables used to build calibration was further reduced from 2 075 to 690 in all of 3 models.

SHOOT ORGANOGENESIS FROM LEAF EXPLANTS IN JAPANESE PEAR (PYRUS PYRIFOLIA)
Acta Horticulturae, 2004The effect of benzyladenine (BA) and thidiazuron (TDZ) in combination with -naphthaleneacetic acid and indole-3-butyric acid (IBA) on in vitro shoot regeneration from leaf segments of several Japanese pears was investigated. A regeneration protocol was developed and regeneration was achieved from six cultivars: – ‘Kosui’, ‘Hosui’, ‘Niitaka’, ‘Wasekaso’,
