The SlPPC2 phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) gene from tomato (Solanum lycopersicum) is differentially and specifically expressed in expanding tissues of developing tomato fruit. We recently showed that a 1966 bp DNA fragment located upstream of the ATG codon of the SlPPC2 gene (GenBank AJ313434) confers appropriate fruit-specificity in transgenic tomato. In this study, we fur...

Tomato (Solanum lycopersicum) is a model plant for studying fleshy fruit development. Several genetic and molecular approaches have been developed to increase our knowledge about the physiological basis of fruit growth, but very few data are yet available at the proteomic level. The main stages of fruit development were first determined through the dynamics of fruit diameter and pericarp cell n...

MADS-domain proteins are important transcription factors involved in many biological processes of plants. In our study, a tomato MADS-box gene, SlFYFL, was isolated. SlFYFL is expressed in all tissues of tomato and significantly higher in mature leave, fruit of different stages, AZ (abscission zone) and sepal. Delayed leaf senescence and fruit ripening, increased storability and longer sepals w...

With the aim of determining whether grafting could improve salinity tolerance of tomato (Lycopersicon esculentum Mill.), and what characteristics of the rootstock were required to increase the salt tolerance of the shoot, a commercial tomato hybrid (cv. Jaguar) was grafted onto the roots of several tomato genotypes with different potentials to exclude saline ions. The rootstock effect was asses...

Messenger RNAs homologous to a cDNA clone (pTOM 13) derived from a ripe-tomato-specific cDNA library are expressed during tomato fruit ripening and after the wounding of leaf and green fruit material. Both responses involve the synthesis of the hormone ethylene. Accumulation of the pTOM 13--homologous RNA during ripening is rapid and sustained, and reaches its maximum level in orange fruit. Fol...

Phosphorus (P), an element required for plant growth, fruit set, fruit development, and fruit ripening, can be deficient or unavailable in agricultural soils. Previously, it was shown that over-expression of a proton-pyrophosphatase gene AVP1/AVP1D (AVP1DOX) in Arabidopsis, rice, and tomato resulted in the enhancement of root branching and overall mass with the result of increased mineral P acq...

to determine the relationship between yield and components of it and identify the effective traits on yield, 97 tomato landraces from west azarbaijan in iran (83 landraces) and iğdır in turkey (14 landraces) along with three commercial cultivars were studied using an alpha lattice design with two replications. the experiment was carried out at the agriculture and natural resources research cent...

The role of sucrose synthase (SuSy) in tomato fruit was studied in transgenic tomato (Lycopersicon esculentum) plants expressing an antisense fragment of fruit-specific SuSy RNA (TOMSSF) under the control of the cauliflower mosaic virus 35S promoter. Constitutive expression of the antisense RNA markedly inhibited SuSy activity in flowers and fruit pericarp tissues. However, inhibition was only ...

evaluating fertilizer quality is important in selecting the appropriate fertilizers for agricultural production. in this experiment, the effectiveness of composite inorganic fertilizer (cif), composite organic fertilizer (cof) and foliar spray of multi-nutrients (fsmn) on the growth, yield, and fruit quality of cherry tomato (lycopersicon esculentum mill.) were compared. the results showed that...

Plant cuticles on outer fruit and leaf surfaces are natural macromolecular composites of waxes and polyesters that ensure mechanical integrity and mitigate environmental challenges. They also provide renewable raw materials for cosmetics, packaging, and coatings. To delineate the structural framework and flexibility underlying the versatile functions of cutin biopolymers associated with polysac...
