Data from: Solanum lycopersicum CLASS-II KNOX genes regulate fruit anatomy via gibberellin-dependent and independent pathways
<p>The pericarp is the predominant tissue determining the structural characteristics of most fruits. However, the molecular and genetic mechanisms controlling pericarp development remain only partially understood. Previous studies have identified that CLASS-II KNOX genes regulate fruit size, shape, and maturation in Arabidopsis thaliana and Solanum lycopersicum. Here we characterized the roles of the Solanum lycopersicum CLASS-II KNOX (TKN-II) genes in pericarp development via a detailed histological, anatomical, and karyotype analysis of the TKN-II knockdown (35S:amiR-TKN-II) fruits. We identify that 35S:amiR-TKN-II pericarps contain more cells around their equatorial perimeter and fewer cell layers than the control. In addition, the cell sizes but not the ploidy levels of these pericarps were dramatically reduced.</p> <p>Further, we demonstrate that fruit shape and pericarp layer number phenotypes of the 35S:amiR-TKN-II fruits can be overridden by the procera mutant, known to induce a constitutive response to the plant hormone gibberellin. However, neither the procera mutation nor exogenous gibberellin application can fully rescue the reduced pericarp width and cell size phenotype of 35S:amiR-TKN-II pericarps. Our findings establish that TKN-II genes regulate tomato fruit anatomy, acting via gibberellin to control fruit shape but utilizing a gibberellin-independent pathway to control the size of pericarp cells.</p>
Evaluación del potencial ecotoxicológico de extractos del género Piper en semillas y crecimiento de plántulas de Lactuta sativa (lechuga), Solanum lycopersicum (tomate) y Theobroma cacao (cacao)
<p>El uso intensivo de agroquímicos en la agricultura tiene un grave impacto en la salud de los seres humanos y en el ambiente, al causar un deterioro de los suelos, propagar enfermedades agrícolas debido a la contaminación de los cultivos, aguas y suelos, y estar asociado con la pérdida aproximada del 70% de las especies vegetales. Por lo anterior, es necesario buscar nuevas alternativas, como productos a base de sustancias naturales que permitan hacer control biológico, que sean más accesibles, no generen un riesgo para los organismos y que puedan ser degradados fácilmente. Un ejemplo son las especies de plantas del género Piper que tienen efecto antifúngico frente al hongo fitopatógeno (Moniliophthora roreri) que ataca la planta de cacao, pero que para establecer su potencial como biofungicida, aún no tienen estudios ecotoxicológicos. La investigación tuvo como objetivo evaluar el efecto de cuatro extractos etanólicos del género Piper (P. peltatum (hojas y tallos), P. eriopodon, y P. pesaresanum) en la germinación y crecimiento de lechuga, tomate y cacao; así como establecer la relación de estos resultados con el contenido de fenoles y flavonoides. Se realizaron bioensayos de germinación en semillas de lechuga, tomate y cacao en cajas de Petri, dejando en incubación durante 7 días con disoluciones de los extractos a 1000 y 500 ppm (CE90. y CE50), para después realizar conteo de semillas germinadas y mediciones de las longitudes de raíces, tallos y brotes. Adicionalmente, en microplaca de 96 pozos se realizó la cuantificación del contenido de fenoles y flavonoides presentes en los extractos mediante las pruebas de Folin-Ciocalteu y AlCl3. Se determinó que la germinación para las tres semillas se vio afectada mayoritariamente por los extractos a la mayor concentración, sin embargo, los extractos que presentaron menor toxicidad fue P. peltatum y P. pesaresanum a la concentración de 500 ppm. Así mismo, el extracto que presentó menor inhibición en las medidas de raíces, tallos y brotes fue P. eriopodon (20-30%). Finalmente, P. eriopodon y P. peltatum fueron los extractos con mayor contenido de fenoles con valores de 50 y 30 mg AG/g extracto, respectivamente, y P. peltatum presentó los mayores valores de flavonoides con valores de 38 y 33 mg QE/g para los extractos de tallos y hojas, respectivamente. Los resultados comprobaron que es posible postular a los extractos de P. peltatum (hojas y tallos), P. eriopodon, y P. pesaresanum a concentraciones de 500 ppm como alternativa para el control de hongos fitopatógenos debido a que no representa una toxicidad alta frente a las especies evaluadas.</p>

Fig. 3. Biosynthetic pathway of ketocarotenoids and ketocarotenoid esters. CRTZ and CRTW are the bacterial carotenoid hydroxylase and oxygenase enzymes respectively. The PYP gene facilitates the esterification with fatty acids to generate ketocarotenoid esters. Phoenicoxanthin and astaxanthin accumulate within the genotypes assessed and esterified forms of these have been observed in this work.
