In vitro propagation of Pyrus pyrifolia

Scientia Horticulturae, 1984
Abstract A micropropagation method for an adult seedling tree of Pyrus pyrifolia Burm. f. is described. Shoot cultures were established and multiplied on media containing benzylamino purine and naphthaleneacetic acid, rooted on media containing naphthaleneacetic acid and phloroglucinol, and transplanted to potting mix. Addition of phloroglucinol to

Screening of Pyrus pyrifolia genotypes for resistance to Alternaria alternata

Scientia Horticulturae, 2020
Abstract Black spot disease (BSD) caused by the fungus Alternaria alternata is one of the most devastating diseases in pear. Most cultivated sand pear (Pyrus pyrifolia Nakai) and its hybrids are susceptible to this disease, and the main measures for the disease control are bagging and spraying of fungicides.

The role of Ca2+ and Ca2+ channels in the gametophytic self-incompatibility of Pyrus pyrifolia

Cell Calcium, 2016
In 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, 2011
Many 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.
