Sucrose synthase in wild tomato Lycopersicon chmielewskii and tomato fruit sink strength

Abstract

Here it is reported that sucrose synthase can be readily measured in growing wild tomato fruits (Lycopersicon chmielewskii) when suitable methods are adopted during fruit extraction. The enzyme also was present in fruit pericarp tissues, in seeds, and in flowers.In mature, nongrowing fruits, sucrose synthase activities approached nil values.Therefore, sucrose synthase can serve as an indicator of sink strength in growing tomato fruits.
