[agglutination of Mesophyll Plastids and Obliteration of Phloem Sieve Tubes Are the Total Result of Seasonal Pauses in Photosynthate Export].

Chloroplast agglutination and sieve tube obliteration are related to the different plant tissues: the agglutination--to the leaf mesophyll, and the obliteration--to the axis phloem. Being equally produced by photosynthate export dynamics, both phenomena are synchronous and can be used for diagnostics of seasonal flashes and pauses of photosynthetic activity… (More)
