Plant mitochondria use two pathways for the biogenesis of tRNAHis
All tRNA(His) possess an essential extra G(-1) guanosine residue at their 5' end. In eukaryotes after standard processing by RNase P, G(-1) is added by a tRNA(His) guanylyl transferase. In prokaryotes, G(-1) is genome-encoded and retained during maturation. In plant mitochondria, although trnH genes possess a G(-1) we find here that both maturation pathways can be used. Indeed, tRNA(His) with o...
متن کاملtRNAHis-guanylyltransferase establishes tRNAHis identity
Histidine transfer RNA (tRNA) is unique among tRNA species as it carries an additional nucleotide at its 5' terminus. This unusual G(-1) residue is the major tRNA(His) identity element, and essential for recognition by the cognate histidyl-tRNA synthetase to allow efficient His-tRNA(His) formation. In many organisms G(-1) is added post-transcriptionally as part of the tRNA maturation process. t...
متن کاملAn exceptional role for flowering plant physiology in the expansion of tropical rainforests and biodiversity.
Movement of water from soil to atmosphere by plant transpiration can feed precipitation, but is limited by the hydraulic capacities of plants, which have not been uniform through time. The flowering plants that dominate modern vegetation possess transpiration capacities that are dramatically higher than any other plants, living or extinct. Transpiration operates at the level of the leaf, howeve...
متن کاملThe Proleptic Accusative as an exceptional Exceptional Case Marking construction
This paper presents a detailed analysis of the so-called proleptic accusative. This construction type is rare, but attested in a number of different languages. Here, we discuss data from Middle Dutch in particular, which enables us to shed new light on the matter. We show that the proleptic accusative is crucially different from complex cases of raising. Instead, we explore two novel and compet...
متن کاملNon-canonical Translation in Plant RNA Viruses
Viral protein synthesis is completely dependent upon the host cell's translational machinery. Canonical translation of host mRNAs depends on structural elements such as the 5' cap structure and/or the 3' poly(A) tail of the mRNAs. Although many viral mRNAs are devoid of one or both of these structures, they can still translate efficiently using non-canonical mechanisms. Here, we review the tool...
