Proteomic analysis of tomato (Lycopersicon esculentum) pollen.
In flowering plants, pollen grains are produced in the anther and released to the external environment with the primary function of delivering sperm cells to the female gametophyte. This study was conducted to identify proteins in tomato pollen and to analyse their roles in relation to pollen function. Tomato is an important crop which is grown worldwide and is an excellent experimental system....
متن کاملMeiosis in sesquidiploid hybrids of Lycopersicon esculentum and Solanum lycopersicoides.
We have synthesized diploid hybrids between Lycopersicon esculentum and Solanum lycopersicoides and have converted them to allotetraploids. Two sesquidiploids, having two complements of the former parent and one of the latter, have been obtained by backcrossing the former parent with the alloploid. In meiosis of the sesquidiploid the L. esculentum chromosomes exhibit strong preferential pairing...
متن کاملIn 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...
متن کاملMi-1.2 Transcripts Accumulate Ubiquitously in Resistant Lycopersicon esculentum.
The tomato Mi-1.2 gene confers resistance against both root-knot nematodes and the potato aphid. Plants are resistant to nematodes early in root development. However, plants as old as 4 weeks are susceptible to aphid infestation. We monitored Mi-1.2 expression at the transcriptional level in resistant (Mi/Mi) and susceptible (mi/mi) tomato cultivars by means of RT-PCR. Mi-1.2 transcripts accumu...
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 ...
