NAC (NAM, ATAF, and CUC) transcription factors are important regulator in abiotic stress and plant development. However, knowledge concerning the functions of plant NAC TFs functioning in stress tolerance and the underlying molecular basis are still limited. In this study, we report functional characterization of the NAC TF, PbeNAC1, isolated from Pyrus betulifolia. PbeNAC1 were greatly induced...

in order to micropropagate of four vigorous rootstocks of pear, including pyrus betulifolia, konjuni, dargazi and gh1, effects of basic plant culture media (ms, ql and modified ql), cytokinins and auxins on productivity, proliferation and rooting were studied in seed and plant improvement institute, karaj. the highest amount of productivity for all rootstocks was observed in ql medium. among pe...

Drought is one of the major abiotic stresses limiting advancement pear industry in arid and semiarid regions China. Currently, production seedlings mainly depends on grafting propagation rootstocks from Pyrus betulaefolia Bunge calleryana Decne. However, limited information available drought stress potential these rootstocks. Here, we conducted pot experiments with controlled watering condition...

Bud exudates from twelve clones o f Populus nigra originating from seven countries were analyzed by gas chromatography-mass spectrometry and the principal compounds identified. Specimens o f P. nigra var betulifolia differed in bud exudate composition from the other speci­ mens analyzed, and were more similar in exudate composition to P. deltoides than were the other specimens. The range o f bu...

The oriental aphid Schizaphis piricola (Matsumura) is recorded for the first time in Europe, on the ornamental pear tree Pyrus calleryana in landscaped areas in Madrid (Spain). Data on the morphology of the forms on primary host (apterous and alate fundatrigeniae and fundatrices), and their biology and distribution are given. The keys for identifying species of Schizaphis (Schizaphis) in the Ib...

Ficus palmata, Pyrus pashia and Ficus auriculata are the popular wild edible fruits of Uttarakhand. The present study aimed to evaluate their total phenolic, flavonoid contents, antioxidant and antiproliferative activities by using two solvents namely 80% aqueous methanol and acetone. The results showed highest phenolic and flavonoid contents in the Ficus palmata acetone extract, while lowest i...
