In vitro flowering and fruiting in tomato (Lycopersicon esculentum Mill.)
In vitro flowering and fruiting were induced in plants regenerated from calli of leaf explants of Lycopersicon esculentum var. Pant 11. MS medium supplemented with 2 mg/l BAP displayed the best response followed by MS with 2 mg/l BAP, 1 mg/ l ABA and 0.5 mg/l IAA. Flower buds were developed both directly from callus and regenerated plantlets from leaf explants under 16 h (39.3 μmol m-2s-1) phot...

Five-week-old tomato plants (Lycopersicon esculentum) cv. Perkoz grown in pots containing garden soil in a growth chamber were submitted to 50 or 150 mM NaCl for 1 h, 2 and 5 days. Tomato leaf anatomy generally did not change after short time salinity, except 5-day-treatment with 150 mM NaCl, where changed cell shape (shrunk and deformed) simultaneously with increased volume of intercellular sp...
متن کاملPrecocious meiotic centromere separation of a novel yeast chromosome.
In Saccharomyces cerevisiae, a reciprocal translocation between chromosome II and a linear plasmid carrying a centromere (CEN6) has split chromosome II into two fragments: one, approximately 530 kilobase pairs (kbp) in size, has the left arm and part of the right arm of chromosome II; the other, a telocentric fragment approximately 350 kbp in size, has CEN6 and the rest of the right arm of chro...
متن کاملمطالعه اندامزایی گل در گوجهفرنگی (Lycopersicon esculentum Mill.)
گوجهفرنگی از مهمترین گیاهان باغی و عضوی از تیره سیبزمینی است. با وجود اهمیت این گونه به عنوان یک مدل ژنتیکی، اطلاعات اندکی از روند نمو گل در این گونه در دسترس است. در مطالعه حاضر، اندامزایی گل در گوجهفرنگی توسط میکروسکوپ نوری بازتابشی مطالعه شد. گلها پنج پر بودند و آغازش حلقههای گل با الگوی رو به محور و بدون همپوشانی صورت گرفت. آغازش اندامها در هر یک از حلقههای کاسبرگ، گلبرگ و پرچم به ...
متن کاملTissue Culture Studies in Tomato (lycopersicon Esculentum) Var. Moneymaker
A protocol was developed for callus induction and regeneration in tomato (Lycopersicon esculentum) var. Moneymaker. Hypocotyl and leaf disc explants of tomato were used as a starting material for callus induction. Explants were cultured on MS medium having different concentrations of hormones. Maximum callogenesis from hypocotyls was obtained on MS medium supplemented with IAA (2 mg/l), NAA (2 ...
