The present invention relates to novel plants, in particular to pepper plants capable of producing fruits which can be kept a longer period of time on the plant as well as being stored after harvesting under refrigerated conditions without exhibiting excessive softening. The invention thus refers to pepper plant which produces fruits with significantly increased fruit firmness at the harvesting stage, wherein said increased fruit firmness is controlled by a genetic determinant, monogenic, wherein said increased fruit firmness is defined as a fruit deformation under a 1 kg load force that is lower than that of a fruit from a control pepper plant which does not have the said genetic determinant.

Pepper plants producing fruits with improved properties

The present invention discloses composition and methods for reducing the weight loss and/or preserving the natural gloss of post-harvest edible plant matter. In particular, the methods comprising applying to the surface of the plant matter a composition comprising an edible wax having a melting temperature below 70&#xb0; C.; a hydrocolloid; a fatty acid; an emulsifier; and water, wherein said edible wax is present in a weight percent ranging from about 10% to about 25% of the total weight of the composition.

Edible coating for plant matter

The present invention relates to a rapid and large-scale production of tomato mutants by utilizing a miniature tomato plant which can be crossed with tomato commercial plants. Mutations are induced in the miniature tomato cultivars and desired mutants are subsequently identified in the resulting mutant tomato population.

Synchronous ripening of tomatoes

In accordance with the present invention, there are provided methods to modulate plant lignification. For example, the level of the enzyme phenylalanine ammonia-lyase (PAL), a key enzyme in the production of lignin precursors, can be increased or decreased, as desired, to increase or decrease lignification levels. Alternatively, the level of lignin precursors in the plant can be modulated either by enhancing the plant's ability to produce such precursors, or by causing the compounds which are required for the production of lignin precursors to undergo alternative chemical conversions (which prevent the incorporation of such compounds into lignin by diverting the lignin precursors to other chemical pathways). In addition, there is provided a method for producing plants having modified lignin composition and content, by converting a portion of the cinnamic acid in said plant to styrene. In another embodiment, there is provided a method for producing styrene and/or styrene derivatives, by contacting cinnamic acid or a cinnamic acid derivative with PAD under decarboxylation conditions.
