- Abstract:
- ... • During harvest, fleshy berry tomato fruits (Solanum lycopersicum) were wounded at their stem scar. Within 3 d, this wound was rapidly sealed by a process covering the wound site with a membranous layer which effectively protects the tomato fruit from excessive water loss, nutrient elution and the entry of pathogens. • Chemical analysis of the de novo synthesized stem scar tissue revealed the pre ...

- Abstract:
- ... • Hereditary symbioses between fungal endophytes and grasses are relatively recent in the history of plant life. Given < 80 million yr of co‐evolution, symbioses are likely to have impacted plant microevolutionary rather than macroevolutionary processes. Therefore, we investigated the microevolutionary role of the fungal endophyte Neotyphodium lolii in the adaptive differentiation of its host spec ...

We partitioned daytime g (gday) and gnight responses by describ ...

The high heat capacity of thick leaves can damp this rapid change in temperature. However, little is known about the extent to which increased leaf thickness can reduce thermal damage, or how thick leaves would need to be to have biological significance. We evaluated quantitati ...

However, the regulation of the shikimate pathway is still far from being understood. We hypothesized that 3‐deoxy‐d‐arabino‐heptulosonate 7‐phosphate synthase (DAHPS) is a key enzyme regulating flux throu ...

The symbiont (Sinorhizobium meliloti) and the root knot‐nematode pathogen (Meloidogyne incognita) induce the formation of new root organs, the nodule and the gall, respectively. • Using laser‐assisted microdissection, we specifically monitored, at the cell ...
