... defense priming via systemic acquired resistance (SAR), or induced systemic resistance (ISR), affects tomato development and growth. We found that defense priming can promote, rather than inhibit, plant development, and that defense priming and growth trade-offs can be uncoupled. Cytokinin response...

... signaling, have never been shown to be involved in ovule initiation. Here, we provide molecular and genetic evidence that points to DELLA proteins as novel players in the determination of ovule number in Arabidopsis and in species of agronomic interest, such as tomato and rapeseed, adding a new layer...

... , but appears to be conserved in diverse higher plant species. In this Review, we highlight the commonalities and differences between CLAVATA-WUSCHEL pathways in different species, with an emphasis on Arabidopsis , maize, rice and tomato. We focus on stem cell control in shoot meristems, but also briefly...

... spatial and temporal resolution in order to test its function in leaf formation and phyllotaxis. Using amplified femtosecond laser pulses, we ablated the internal tissues in young leaf primordia of tomato ( Solanum lycopersicum ) without damaging the overlying L 1 and L 2 layers. Our results show...

... of the genome in the absence of mitosis. In tomato, very high ploidy levels (up to 256C) are reached during fruit development, concomitant with very large cell sizes. Using cellular approaches (fluorescence and electron microscopy) we provide a structural analysis of endoreduplicated nuclei at the level...

... of mutants in the tomato ( Solanum lycopersicum ) CIN-TCP gene LANCEOLATE ( LA ) led us to hypothesize that a threshold LA-like activity promotes leaf differentiation. Here, we examined the relationship between LA activity, leaf maturation, and final leaf size and shape. Leaves of diverse shapes from various...

In tomato, prolonged leaf patterning enables...

... ), from the meristem by a superficial incision leads to defects in dorsoventral patterning of the isolated primordium. (A) Tomato apex immediately after isolation of I 1 by an ablation of the superficial L 1 layer (black arrowheads). (B) Semi-thin section of a tomato apex immediately after isolation...

... leaf dorsiventral symmetry affects leaflet formation in species with compound leaves is largely unknown. In four non-allelic dorsiventrality-defective mutants in tomato, wiry, wiry3, wiry4 and wiry6 , partial or complete loss of ab-adaxiality was observed in leaves as well as in lateral organs...

...Lilac Pnueli; Lea Carmel-Goren; Dana Hareven; Tamar Gutfinger; John Alvarez; Martin Ganal; Daniel Zamir; Eliezer Lifschitz ABSTRACT Vegetative and reproductive phases alternate regularly during sympodial growth in tomato. In wild-type ‘indeterminate’ plants, inflorescences are separated by three...

...Andrea Mazzucato; Anna Rita Taddei; Gian Piero Soressi ABSTRACT Among the different sources of genetic parthenocarpy described in tomato, the mutation referred to as parthenocarpic fruit ( pat ) is of particular interest because of its strong expressivity and because it confers earlier ripening...
