“Asfixia” dos oceanos

A redução de oxigénio nos oceanos é o fator com mais impacto negativo nos organismos marinhos. Esta é a principal conclusão de um estudo publicado na revista Nature Ecology and Evolution, liderado por membros do Laboratório Marítimo da Guia do Centro de Ciências do Mar e do Ambiente, polo da Ciências ULisboa, segundo comunicado de imprensa emitido esta segunda-feira.

In vitro germination of seeds in order to develop cotyledons under sterile conditions to be used as source material for genetic transformation and plantlet regeneration purposes, and subsequent production of tomato plants edited with CRISPR-Cas9.

Germinação de sementes in vitro no sentido de obter cotilédones como explante para transformação genética e regeneração de plântulas, levando à produção de tomateiros editados geneticamente com CRISPR-Cas9.

We invite you to look at Nature. Find those secret corners, pieces that were left over, the apparently abandoned spots of a garden (yours or nearby). You may be surprised by finding a web of interactions. If you look at natural systems, you rarely find plants growing in evenly spaced out straight lines – instead, polycultures are Nature’s way of cultivating. Moreover, besides plants, there is an intricated web of life and relationships between them, animals (especially insects) and fungi. In all these relations, there is competition, parasitism, and symbiosis.

The soils in the city are generally eroded and polluted, so when it comes to urban gardening, soil regeneration is one of the main challenges.
