“…This close connection of tRNA composition and differentiation status has already been shown for wheat and mimosa tissues. [22] Another factor is the general difference in the culture conditions. Since cells in cell culture can uptake nutrients from the culture medium, they are, in contrast to real plants, not forced to perform photosynthesis to grow.…”

We report an efficient synthesis of the hypermodified natural tRNA modifications wybutosine (yW) and hydroxywybutosine (OHyW). We also describe the preparation of isotopically labeled analogues for precise quantification of yW and OHyW in different tissues including plant materials. The synthesis involved the formation of the unusual tricyclic ring structure of the bases by using a catalytic, intramolecular hydroamination reaction. The basis for the synthesis is also a stereoselective coupling reaction that allows the introduction of the fully substituted side chains to the tricyclic core structure. The isotopologues of yW and OHyW, together with other isotopically labeled tRNA modifications, were ultimately used in LC-MS quantification experiments to investigate the role of the modified bases in the translational process. Quantification was performed in the plant species Arabidopsis thaliana.

Quantitative Changes in Ribonucleic Acids of Potato Plants in Response to Photoperiod and Temperature1,2

Quantitative changes in 4S, ribosomal and tenaciously bound RNA occurred in response to various combinations of temp and photoperiod. Short days accompanied by low temp (SD/LT) elicited an increase in ribosomal RNA, whereas RNA decreased with time in a long day, high temp (LD/HT) regime. Plants exposed to a LD/HT regime had reduced levels of RNA even after 5 or 9 days of pretreatment in a SD/LT environment. It appears that the quantitative variations of RNA in the SD/LT and LD/HT regimes are due primarily to RNA synthesis rates rather than to changes in ribonuclease activity. Temperature had a marked influence on ribosomal RNA level in potato plants while the response to photoperiod was not as great.
