| Abstract |
Rab protein family is the largest subfamily of small G protein family. As one of the most important families in plant, Rab family plays an important role in the process of plant growth and development. So far, the identification of 57 members of the Rab family in Arabidopsis has been completed. In cotton, the relevant family has not been reported. Here, we identified 87, 169, 136, 80 Rabs in the four sequenced cotton species, G. raimondii (D5), G. hirsutum acc. TM-1 (AD1), G. barbadense acc. 3-79 (AD2) and G. arboreum (A2), respectively. Biological information analysis showed that the number of amino acid is 200-300 aa among Rab family members in G. raimondii and the protein molecular weight is between 20 and 30 kDa, which is consistent with the characterization of the Rab protein itself. 87 GrRabs in G. raimondii are divided into eight groups. In each group, intron numbers and subcellular localization of Rab protein are basically the same. We mapped the distribution of GrRab genes on 13 chromosomes of G. raimondii except two genes. Among the 87 GrRabs in G. raimondii, we identified 60 pairs of GrRabs formed in whole genome duplication. Among all the gene pairs, the Ka/Ks values were less than 1. This indicates that it is the results of the purification selection and will help maintain the conservation of gene in structure and function. Further, 4 of the 87 GrRabs showed tandem duplication. They were GrRabA2a vs GrRabD1a and GrRabA2h vs GrRabD1b respectively. Expression patterns analysis of 169 GhRabs in G. hirsutum acc. TM-1 indicates that most Rab family members play a certain role in different tissues/organs and different growth stages of cotton, implying their potential function in the polar growth of pollen tube, root hair and fiber cell, as well as improving stress and disease tolerance. The systematic investigation of Rab genes in cotton will lay a foundation for understanding the functional roles of different Rab members in the polar growth and stress tolerance. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 04 June 2017.
All research outputs
#19,951,180
of 25,382,440 outputs
Outputs from Botanical Studies
#110
of 188 outputs
Outputs of similar age
#240,235
of 331,648 outputs
Outputs of similar age from Botanical Studies
#2
of 4 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 188 research outputs from this source. They receive a mean Attention Score of 4.5. This one is in the 36th percentile – i.e., 36% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 331,648 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 4 others from the same source and published within six weeks on either side of this one. This one has scored higher than 2 of them.
