Possible role of growth regulators in adaptation to heat stress affecting partitioning of photosynthates in tomato plants

Abstract


The formation of polyribosomes and total dehydrogenase activity in rye grains from different harvest years (with different viability) were studied. It was found using actinomycin D and cordycepin that grain aging was related to a lower ability for RNA synthesis and polyribosome formation. At least part of the stored form of RNA (preformed mRNA) in the embryos of both aged non-viable grain was able to form complexes with ribosomes.
