#> [1] "© 2020, The Author(s).Aluminium (Al) toxicity is the single most important contributing factor constraining crop productivity in acidic soils. Hydroponics based screening of three rice genotypes, a tolerant (ARR09, AR), a susceptible (IR 1552, IR) and an acid soil adapted landrace (Theruvii, TH) revealed that AR accumulates less Al and shows minimum decrease in shoot and root biomass under Al toxicity conditions when compared with IR. Transcriptome data generated on roots (grown in presence or absence of Al) led to identification of ~1500 transcripts per genotype with percentage annotation ranging from 21.94% (AR) to 29.94% (TH). A total of 511, 804 and 912 DEGs were identified in genotypes AR, IR and TH, respectively. IR showed upregulation of transcripts involved in exergonic processes. AR appears to conserve energy by downregulating key genes of glycolysis pathway and maintaining transcript levels of key exergonic step enzymes under Al stress. The tolerance in AR appears to be as a result of novel mechanism as none of the reported Al toxicity genes or QTLs overlap with significant DEGs. Components of signal transduction and regulatory machinery like transcripts encoding zinc finger protein, calcieurin binding protein and cell wall associated transcripts are among the highly upregulated DEGs in AR, suggesting increased and better signal transduction in response to Al stress in tolerant rice. Sequencing of NRAT1 and glycine-rich protein A3 revealed distinct haplotype for indica type AR. The newly identified components of Al tolerance will help in designing molecular breeding tools to enhance rice productivity in acidic soils."

4 years ago Thank you for the speedy response. I have reached out to Elsevier via email to see if they can provide me more details on my API capabilities.
My hope is to develop a script that extract just the abstract information to a vector of character strings from an rscopus search. To start this code, I have created an if statement that creates the search, and extracts a list of just rscopus ID numbers:
Before I write a loop that can take each scopus ID and extract just the abstract, I want to test it with just one entry to make sure the function can provide just one abstract:
However, when I use this code, it comes NULL for the abstract information.
It should be stated that names(data) only retrieves the fields 'affiliation' and 'coredata'. Is there something that I have missed? I have attached Session_Info_9June2020.txt , for more detail.
