Temperature, But Not Ethephon, Influences Fruit pH of Processing Tomato

Influences of irrigation interval,nitrogen fertilization and plant spacing on tomato fruit yield and quality

Rigid facial motion influences featural, but not holistic, face processing

We report three experiments in which we investigated the effect of rigid facial motion on face processing. Specifically, we used the face composite effect to examine whether rigid facial motion influences primarily featural or holistic processing of faces. In Experiments 1-3, participants were first familiarized with dynamic displays in which a target face turned from one side to another; then ...

Ripening-regulated susceptibility of tomato fruit to Botrytis cinerea requires NOR but not RIN or ethylene.

Fruit ripening is a developmental process that is associated with increased susceptibility to the necrotrophic pathogen Botrytis cinerea. Histochemical observations demonstrate that unripe tomato (Solanum lycopersicum) fruit activate pathogen defense responses, but these responses are attenuated in ripe fruit infected by B. cinerea. Tomato fruit ripening is regulated independently and cooperati...

Tomato hydroxymethylglutaryl-CoA reductase is required early in fruit development but not during ripening.

The activity of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) and the level of its mRNA have been determined at various stages of tomato fruit development. The HMGR reaction makes mevalonate, a necessary component in the synthesis of all isoprene containing compounds, such as sterols and carotenoids. A cDNA clone encoding the active site region of HMGR has been isolated from a tomato l...

In vitro synthesis and processing of tomato fruit polygalacturonase.

The in vitro processing of tomato fruit polygalacturonase (PG) (poly[1,4-alpha-d-galacturonide]glucanohydrolase, EC 3.2.1.15) was studied. Complete chemical deglycosylation of a mixture of mature, purified PG 2A and PG 2B isozymes (45 and 46 kilodaltons; respectively) with trifluoromethane sulfonic acid yielded a single polypeptide of 42 kilodaltons. Similarly, N-terminal amino acid sequencing ...
