ncodes a carboxylesterase or triacylglycerol lipase and has been shown to physically interact with EDS1, and Cit. 373. 1. S1 x at is similar to UBQ10. The EDS1 like citrus gene was up regulated at the early stage and at the very late stage in only one of the four studies, and most of 15 hub genes that interact with the citrus EDS1 like gene were reference 4 also up regulated by the Las infection in some of the studies with the exception of Cit. 373. 1. S1 x at, Cit. 39054. 1. S1 s at and Cit. 10182. 1. S1 s at. Therefore, the finding that so many HLB responsive hub genes in cit rus connect to EDS1, which is critical for disease resistance in Arabidopsis and other plants, indicates that EDS1 mediated defense response mechanism might be im portant in citrus response to the HLB bacterial infection at least at early stage.

Cit. 12214. 1. S1 s at represents a transcription factor most closely related to Arabidopsis NAC096. Mapping this Probe set as the seed node to the HLB response network with the second degree neighbors resulted in an NAC096 subnet work. Two Inhibitors,Modulators,Libraries medium size hubs were identified in this subnetwork, Cit. 10032. 1. S1 x at and Cit. 15606. 1. S1 at, both of which were up regulated transcriptionally by the Las infection. Cit. 10032. 1. S1 x at represents a GA responsive GAST1 homolog and has been reported to be responsive to other hormones such as BR and ABA. Cit. 15606. 1. S1 at has interactions with 15 Probe sets and is closely related to At1g80130 which encodes Arabidopsis tetratricopeptide repeat like superfamily protein and is responsive to oxidative stress.

Given that both GA response and oxidative stress response have been implicated an important role in a relatively resistant variety Inhibitors,Modulators,Libraries US 897 in response to the Las Inhibitors,Modulators,Libraries infection at the very late stage, our preliminary analysis of the NAC096 subnetwork supports that transcriptional control involving hormone Inhibitors,Modulators,Libraries response and oxidative stress response might also be important even at the early stage of the HLB bacterial attack. Subnetwork analysis reveals transport process as a key component in the HLB response core subnetwork It is likely that the commonly up regulated genes can de fine a default or core response pathway for citrus plants to resist the attack by the HLB bacteria, we therefore attempted to address whether there is a common subnet work GSK-3 that could be affected by HLB.

We mapped 21 commonly up regulated Probesets into the HLB response network, resulting in the formation of the HLB core sub network. This subnetwork based on the first degree neighbors contains 123 Probesets and 181 inter actions. The hub gene analysis Idelalisib msds shows that the subnetwork has eight large hubs, all of which were up regulated, and four small hubs. Among six categories of biological processes analyzed in the HLB response network, transport and carbohydrate metabolic process were overpresented in this core subnetwork. The Probesets belonging to the three categories, carbo hydrate metabolic process, transport and hormone re sponse,
