The infectious full-length cDNA clone of zucchini yellow mosaic virus (ZYMV) isolate PA (pZYMV-PA), which was isolated from pumpkin, was constructed by utilizing viral transcription and processing signals to produce infectious in vivo transcripts. Simple rub-inoculation of plasmid DNAs of pZYMV-PA was successful to cause infection of zucchini plants (Cucurbita pepo L.). We further engineered th...

This work establishes that cessation of root elongation of intact squash (Cucurbita pepo L.) plants is an early result of boron deficiency. Root elongation is slowed by 6 hours and is virtually stopped as early as 24 hours after boron is first withheld from the nutrient solution. As root elongation ceased, cell elongation progressed distally into the region normally occupied by the apical meris...

Cucurbita pepo L. plants were grown in plastic pots with 2 kg washed sand per pot at three levels of potassium and sodium nitrate supplies to investigate the effects of nitrate supply on nitrate reductase activity and nitrate reductase expression in the leaves of the plants. Results demonstrated that starvation leads to decrease nitrate reductase activity and nitrate reductase expression. Suppl...

Amaç: Bu çal??mada moleküler markörler kullan?larak çerezlik kabaklarda (Cucurbita pepo L.) safl?k düzeylerinin tahmin edilmesi amaçlanm??t?r.Yöntem ve Bulgular: Dominant kodominant markör teknikleri (simple sequence repeats, SSR inter-simple ISSR) yard?m?yla S0 (hiç kendileme yap?lmam??), S1, S2 S3 kademesindeki kabaklar?n düzeyleri ile heterozigotluk aras?ndaki ili?ki edilmi?tir. analizleri s...
