This page gives the information that I have collected from my own literature searches and from others posting on the internet. Please let me know if you feel anything is not clear or is not addressed at all as I am continually updating/modifying it as I get feedback.
Bold print in quotes does not mean that the bold print appeared in the original; the bold print was added by me (H. Kuska) for emphasis. Information in color indicates that a link is present for further information.

The first scientific paper that discussed this virus is:
Title: IDENTIFICATION AND PARTIAL CHARACTERIZATION OF SIX NEW VIRUSES OF CULTIVATED ROSES IN THE USA.

The Rose rugosa leaf distortion virus (RrLDV) was detected in cv. Charles Albanel, a rugosa hybrid that was growing in St. Paul, Minnesota.

H.Kuska comment:
This paper is mainly of interest to plant virologists.

A more recent paper which should be useful to general rosarians has appeared:
Title: SYMPTOMS, TRANSMISSION, AND DETECTION OF FOUR NEW ROSE VIRUSES.
Authors: Mollov , D.(1), Lockhart, B.(1) and Zlesak, D.C.(2)
Authors affiliation:

Rose Symptoms
The disease is characterized by leaf distortion and stunting. Pale circular lines can be observed on early spring growth, see pictures of diseases leaves in Figure 4 in the 2015 publication.
------------------------------------------------------------------------------------------------------
Transmission of the virus
The 2015 paper reported that the disease could be transferred to a healthy cv. Marie Bugnet rugosa hybrid by grafting it to a diseased cv. Charles Albanel rugosa hybrid rose. No other modes of transmission were reported as being tested for.
-------------------------------------------------------------------------------------------------------------
Concerning whether the virus is a temperature sensitive virus.
Since this virus is reported to show symptoms throughout the season, it appears that it is not a temperature sensitive virus.

Similarity to Rose Yellow Leaf Virus (RYLV)
The 2015 paper paper states: "Both RrLDV and RYLV are the only known members of the family Tombusviridae known to infect roses. ......... Despite genomic sequence similarity between both viruses, the RT-PCR assays developed for the detection of RrLDV and RYLV are specific and can discriminate between the viruses."
A recent paper states: "Rose yellow leaf virus (RYLV), a pathogen whose nearly complete nucleotide sequence has been determined recently [25], is considered an isolate of RrLDV (and not a member of a separate species) on the basis of the high sequence identity shared by their corresponding
proteins (90 %, 95 %, 82 %, and 86 %, respectively, for RdRp, CP, MP1 and MP2) [33]."
