| Abstract |
Using quantitative assays for autophagy, we analyzed 4 classes of atg mutants, discovered new atg2 phenotypes and ATG gene interactions, and proposed a model of autophagosome formation in plants. Plant and other eukaryotic cells use autophagy to target cytoplasmic constituents for degradation in the vacuole. Autophagy is regulated and executed by a conserved set of proteins called autophagy-related (ATG). In Arabidopsis, several groups of ATG proteins have been characterized using genetic approaches. However, the genetic interactions between ATG genes have not been established and the relationship between different ATG groups in plants remains unclear. Here we analyzed atg2, atg7, atg9, and atg11 mutants and their double mutants at the physiological, biochemical, and subcellular levels. Involvement of phosphatidylinositol 3-kinase (PI3K) in autophagy was also tested using wortmannin, a PI3K inhibitor. Our mutant analysis using autophagy markers showed that atg7 and atg2 phenotypes are more severe than those of atg11 and atg9. Unlike other mutants, atg2 cells accumulated several autophagic vesicles that could not be delivered to the vacuole. Analysis of atg double mutants, combined with wortmannin treatment, indicated that ATG11, PI3K, and ATG9 act upstream of ATG2. Our data support a model in which plant ATG1 and PI3K complexes play a role in the initiation of autophagy, whereas ATG2 is involved in a later step during the biogenesis of autophagic vesicles. |

Attention Score in Context
This research output has an Altmetric Attention Score of 5. 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 07 July 2020.
All research outputs
#6,313,173
of 23,577,654 outputs
Outputs from Plant Cell Reports
#607
of 2,232 outputs
Outputs of similar age
#126,372
of 443,996 outputs
Outputs of similar age from Plant Cell Reports
#14
of 29 outputs
Altmetric has tracked 23,577,654 research outputs across all sources so far. This one has received more attention than most of these and is in the 73rd percentile.
So far Altmetric has tracked 2,232 research outputs from this source. They receive a mean Attention Score of 4.1. This one has gotten more attention than average, scoring higher than 72% of its peers.
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 443,996 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 71% of its contemporaries.
We're also able to compare this research output to 29 others from the same source and published within six weeks on either side of this one. This one is in the 48th percentile – i.e., 48% of its contemporaries scored the same or lower than it.
