TL;DR: It is shown that in cold, plants become more susceptible to viruses, and RNA silencing‐based phenotypes of transgenic plants are lost, suggesting that the two classes of small RNAs are generated by different nuclease complexes.

TL;DR: R meliloti strain 41 (Rm41) was shown to harbor two indigenous plasmids with molecular weights of 140 Mdal (pRmc41a) and more than 300 Mdal(pRme41b), respectively using a heat-treatment procedure, derivatives of Rm41 defective in nodulation (Nod-) or nitrogen fixation (Fix-) have been readily obtained as discussed by the authors.

TL;DR: The results of this study correlate well with transcription data of nodule-specific expression of plasmid sequences, and are designated as “common” nod genes because mutations in them can be complemented by plasmids derived from different Rhizobium strains.

TL;DR: A circular genetic map of the R. meliloti 41 chromosome is presented and a new approach in the evaluation of conjugational mapping data which may be applicable to other Gram-negative bacteria is described.

TL;DR: This study attempts to identify genes controlling and driving the process of tuber initiation and growth by implementing large-scale transcriptional changes using the newly developed POCI array and will greatly enhance analysis of transcriptional control mechanisms in a wide range of potato research areas.
