Brassinosteroid biosynthesis and signalling in Petunia hybrida
Brassinosteroids (BRs) are steroidal plant hormones that play an important role in the growth and development of plants. The biosynthesis of sterols and BRs as well as the signalling cascade they induce in plants have been elucidated largely through metabolic studies and the analysis of mutants in Arabidopsis and rice. Only fragmentary details about BR signalling in other plant species are know...
متن کاملEffects of Glycerol and Salicylic Acid on Freezing Tolerance of Iranian Petunia (Petunia hybrida L.)
The aim of this study was to investigate the effects of glycerol (GL) and salicylic acid (SA) on freezing tolerance of Iranian Petunia (Petunia hybrida). For this purpose, a factorial experiment based on completely randomized design with three replications was conducted under controlled conditions. The first factor was temperature (0 and -4 °C) and the second factor was spraying with anti-stres...
متن کاملThe S-Ribonuclease Gene of Petunia hybrida
To determine the ability of isolated S-locus promoter sequences to direct organ-specific gene expression, we used microprojectile bombardment to introduce chimeric S-allele/&glucuronidase genes into different tissues of Petunia hybrida for transient expression. Histochemical staining showed that S-locus/B-glucuronidase fusions were expressed in pistil, ovary, and petal tissue. No expression of ...

به منظور بررسی هتروزیس و ترکیب پذیری لاین های اینبرد اطلسی برای صفات زینتی، تلاقی های مستقیم و متقابل بین چهار والد اطلسی با اسامی L5 (P1)، L8 (P2)، L11 (P3) و L17 (P4) انجام و در سال دوم هیبرید های F1 حاصل به همراه والدین در قالب طرح بلوک های کامل تصادفی با سه تکرار کاشته شدند. صفات ارتفاع بوته تا اولین گل، تعداد گل روی بوته، تعداد روز تا گلدهی، قطر گل، قطر لوله گل، طول لوله گل، طول جام گل، م...
متن کاملStylar peroxidase and incompatibility reactions in Petunia hybrida.
Self-, cross- and non-pollinated styles of Petunia hybrida were treated with 3-3'-diaminobenzidine for the ultrastructural localization of peroxidase activity. Wall peroxidases were absent in cross-pollinated styles, but they were detectable as an osmiophilic deposit on the cell walls of the outer portion of the transmitting tissue in self- and non-pollinated styles. The cell layer showing pero...
