Black meristematic fungi are cosmopolitan and able to adapt to extreme fluctuations of ultraviolet radiation, temperature, and moisture and grow in exposed habitats such as stone surfaces. In a survey on fungi associated with fruit rots, leaf spots, canker, gummosis, dieback and trunk diseases of grapevine and walnut trees in Kurdistan Province (Iran), some black meristematic fungal isolates re...

Integrative systems biology proposes new approaches to decipher the variation of phenotypic traits. In an effort to link the genetic variation and the physiological and molecular bases of fruit composition, the proteome (424 protein spots), metabolome (26 compounds), enzymatic profile (26 enzymes), and phenotypes of eight tomato accessions, covering the genetic diversity of the species, and fou...

The plant hormone ethylene is involved in many developmental processes, including fruit ripening, abscission, senescence, and leaf epinasty. Tomato contains a family of ethylene receptors, designated LeETR1, LeETR2, NR, LeETR4, and LeETR5, with homology to the Arabidopsis ETR1 ethylene receptor. Transgenic plants with reduced LeETR4 gene expression display multiple symptoms of extreme ethylene ...

Episodes of water deficit (WD) during the crop cycle of tomato may negatively impact plant growth and fruit yield, but they may also improve fruit quality. Moreover, a moderate WD may induce a plant "memory effect" which is known to stimulate plant acclimation and defenses for upcoming stress episodes. The objective of this study was to analyze the positive and negative impacts of repeated epis...

We isolated the 5’ upstream promoter regions of the fruit-type sucrose synthase (SS) gene from tomato and Japanese pear by inverse PCR. The 5’ region of the tomato SS gene (TOMSSF) contained an intron approximately 1.6 kbp long in the 5’untranslated region, whereas the equivalent 5’ region in the Japanese pear SS gene (PypSUS1) had no intron. Each region was fused to the β-glucuronidase (GUS) g...

Plants were grown in two glasshouse compartments under two vapour pressure de®cit (vpd) levels: low vpd was obtained by increasing air humidity with a fogging system, and high vpd was obtained during sunny hours in a greenhouse where air humidity was not controlled. The mean value, of the six driest hours of the day concerning the growing period of the fruits considered, was 1.6 kPa under low v...

The shedding of plant organs is a highly coordinated process essential for both vegetative and Research with model plants, namely floral organ abscission in Arabidopsis and leaf, flower and fruit abscission of tomato, and seed shattering in rice has provided new insights in to the molecular mechanisms underlying abscission. However, little is known about how these mechanisms that take place in ...
