In the present study, we seek to understand two important development processes with application in tomato production. We will characterize new mutants and natural allelic variations that affect fruit ripening and abscission. The study will be carried out on the tomato cultivar Micro-Tom, a model system for tomato genetics. Both groups in Brazil and Japan have developed extensive collecti…
Current plant breeding approaches have failed to harness the full potential of tolerance to abiotic stress available in wild crop relative species by genetic introgression to crop varieties. This difficulty is due to the highly complex polygenic traits involved in these stresses. Nevertheless, highly-tolerant crops are urgently needed in the face of scarcity of arable land and fresh water…
This project aims to deliver (i) new tomato lines with enhanced salt tolerance for breeding programs. (ii) Fundamental insights into a so far unknown pathway for salt tolerance that is highly relevant for field conditions. (iii) Marker genes and alleles for breeding programs to enhance and stabilize tomato crop yield under adverse growth conditions. (AU)
The aim of this work is to study the regulatory effects of the hormones abscisic acid (ABA) and gibberellins (GAs) in the biosynthesis of secondary metabolism compounds (terpenes and polyphenols) and accumulation of phosynthates in leaves, flowers and fruits of tomato. With this aim, mutants deficient in the biosynthesis of either ABA or GA introgressed into the Micro- Tom cultivar of tom…

The witches broom disease, caused by the basidiomycete Moniliophthora perniciosa [syn. Crinipellis perniciosa (Stahel) Singer; Marasmiaceae s.l.], is the most significant disease of cacao (Theobroma cacao). M. perniciosa can infect a variety of hosts, not only being restricted to cacao, allowing classification in three biotypes, C, L. and S. The C-biotype infects cacao and related species…
The substantial increase in productivity during the Green Revolution can be attributed to several factors, but the change in partition biomass between vegetative and reproductive organs was the major genetic determinant. However, this physiological interpretation of the genetic components of productivity is still little explored in plant breeding. It was previously shown in our lab that t…
Trichomes are epidermal structures that can be classified into two types: glandular or non-glandular, and they are mainly related to plant defense strategies. Little is known about the glandular trichome development pathway, since most of the studies are in Arabidopsis thaliana, a model in which this kind of trichome is absent. The Solanum genus has a wide variety of trichomes, especially…

De novo organogenesis relies on the capacity to regenerate in vitro the entire plant from single somatic cells and it is the most common pathway leading to in vitro plant regeneration. This capacity is frequently used in biotechnological breeding and in vitro plant tissue culture. Organogenesis is highly dependent on phytohormone perception and can be divided in acquisition of competence,…
The ability of certain plant tissues to regenerate new organs has been known for a long time and was used primarily in the domestication of plants that are propagated vegetatively. Later on, efforts to extend this regenerative capacity to in vitro propagation enabled a better understanding of the mechanisms controlling the post-embryonic plant organogenesis. Recent studies on cell signali…
Trichomes are specialized epidermic structures mostly responsible for plant herbivory protection. The Solanum genus has been used as a model to study trichome differentiation. The genus contains a large range of different types of trichomes, including glandular types. Glandular trichomes are called "biochemical factories", since they produce and accumulate specialized metabolites. The cul…
