Availability Zone is an isolated location inside of an Azure Region, and has its own independent power source, network, and cooling. The physical and logical separation of Availability Zones within an Azure region protects applications and data from zone-level failures. Availability Zone data transfer pricing is based on Availability Zones.

The following table summarizes the applicable charges for this configuration. Item Price (USD) Private Service Connect endpoint (load balancer) used to access services in another VPC network All global external HTTP(S) load balancer or internal HTTP(S) load balancer pricing applies Traffic between a Private Service Connect NEG and the managed service $0.01 per GB processed, both egress and ingress Serverless VPC AccessServerless VPC Access is priced as follows. Resource Price Serverless VPC Access connector Charged by the number of instances in your connector. See the pricing for your instance type: f1-micro: N1 shared-core machine types

Network egress Charged at Compute Engine networking rates. Serverless VPC Access connector instances are distributed across zones for increased reliability. The rate is based on which connector instance handles the request and whether the destination resource is in the same zone. Egress to a connector from a serverless resource such as a function, app, or service is not charged. You can view your Serverless VPC Access costs in theGoogle Cloud console by filtering your billing reports by the label keyserverless-vpc-access.Network telemetryNetwork logs generate charges. You are charged for the following products:
Prices are per GB egressed to the internet directly or through Carrier Peering, and are in addition to other network egress fees. For example, for workloads behind a supported Google Cloud load balancer, the data processing fee meters the bits egressed to the internet through the enrolled load balancer endpoints but does not meter the associated inter-region or inter-zone traffic by the underlying workload. The charge is $0.05 per GiB egressed for the first 100 TiB and $0.04 per GiB for the next 400 TiB.

The following pricing applies to all zone types:public, private, and forwarding. All zone types are aggregated for purposes ofpricing. For example, if you have 10 public zones, 10 private zones, and 10forwarding zones, then your pricing is based on having 30 zones. All queries areaggregated as well, regardless of zone type.
* Managed zone pricing is calculated based on the number of managedzones that exist at a time, prorated by the percentage of the month they exist.This prorating is measured by hour. Zones that exist for a fraction of an hourare counted as having existed for the whole hour.
High-performance liquid chromatography analysis showed that BSO treatment led to a 94 and 96% reduction in GSH and hGSH content, respectively, in wild-type roots with nodules (Supplementary Table 4). Nodules on untreated, wild-type plants grown without cotyledons were pink and had typical indeterminate nodule histological organization (Figures 8A,B). A 46% reduction in nodule number was observed in BSO-treated wild-type plants (Supplementary Table 4). Microscopic analysis of BSO-treated nodules revealed a premature degradation of symbiotic structures at the base and center of the nodules, indicative of early senescence (Figures 8C,D). Cyp15a, TPP, PR1, and PR10 expression was upregulated and that of NF-YA1 downregulated in response to (h)GSH depletion in wild-type roots with nodules (Figure 7). Compared with untreated plants, BSO+GSH-treated plants had the same number of nodules and exhibited higher levels of GSH, but not hGSH, in roots with nodules (237 and 88%, respectively) (Supplementary Table 4). This change in thiol content coincided with the upregulation of NF-YA1, Cyp15a, TPP, PR1, and PR10 expression levels in BSO+GSH-treated plants relative to untreated plants (Figure 7). Nodules on the roots of BSO+GSH-treated plants did not show signs of early senescence in the nitrogen fixation zone (Figures 8E,F); however, some cells showed signs of degradation (Figure 8F).

The treatment of wild-type plants with 0.1 mM GSH for 2 weeks led to a twofold increase in GSH content in roots with nodules, but did not affect the hGSH level (Supplementary Table 6). Treatment with 0.1 mM GSH induced the expression of nodule development-related genes (EFD and NF-YA1) in wild-type plants (Figure 10). Meanwhile, treatment with 1 mM GSH elicited a threefold increase in the levels of both thiols (Supplementary Table 6). No prominent morphological differences between GSH-treated and untreated wild-type nodules were observed (data not shown). The expression levels of (h)GSH biosynthesis-related genes, defense response genes (PR1 and PR10), and that of the nodule senescence marker gene Cyp15a were not significantly changed in roots with nodules of GSH-treated wild-type plants (Figure 10).
Except for sym33-2, GSHS expression was significantly upregulated, and that of hGSHS downregulated in nodules of all genotypes and ages compared with that in uninoculated roots. This suggests that bacterial release is necessary for a hGSHS-to-GSHS switch in gene expression in nodule tissue, which is a requirement for nodule development. Meanwhile, GSH1, GSHS, and hGSHS expression was higher in sym40-1 and sym33-3 mutant nodules than in wild-type nodules (Figure 5A), suggestive of a change in thiol metabolism in these mutants associated with defense responses (Ivanova et al., 2015; Tsyganova et al., 2019b).
Taken together, these findings indicate that the GSH:hGSH ratio is an important factor in indeterminate nodule development and functioning. A high GSH:hGSH ratio is associated with bacterial release, the functioning of the nodule meristem, and likely also the differentiation of nitrogen-fixing cells. Indeed, in M. sativa, both GSH and hGSH are present in all organs; however, their ratio varies across organs, being highest in root meristems and lowest in mature leaves and the root elongation zone. GSH was associated with cell-cycle activation in cell suspension cultures, whereas hGSH was associated with differentiated cells (Pasternak et al., 2014).
Nodule development in sym40-1 plants stops after the differentiation of juvenile bacteroids (Tsyganov et al., 1998). Decreased (h)GSH content in nodules may also be associated with plant defense responses triggered by the perception of nodule bacteria as pathogens. Changes in (h)GSH content have been shown to affect defense responses during biotic stress in some legumes (Baldacci-Cresp et al., 2012; Chen et al., 2020). (h)GSH is essential for the growth of parasitic nematode worms that infect plant roots and force the differentiation of root cells into giant cells, forming galls. (h)GSH metabolism differs between galls and uninfected roots. (h)GSH-depleted M. truncatula plants are less affected by infection of root-knot nematodes (Baldacci-Cresp et al., 2012). Hypersensitive response-like cell death and hydrogen peroxide production around the area of nematode infection have been observed in (h)GSH-depleted Glycine max roots (Chen et al., 2020), resembling hydrogen peroxide accumulation in mutant sym40-1 nodules (Tsyganova et al., 2009).
A reduction in (h)GSH synthesis significantly decreased the nodule number in all genotypes tested (Supplementary Table 4). This agreed with that observed for M. truncatula, where the inhibition of (h)GSH synthesis was shown to reduce the number of nascent nodules and lateral roots and the expression of the early nodulin genes ENOD12 and ENOD40 without affecting the number of infection events (Frendo et al., 2005). These observations indicate that the decrease in nodule number observed in BSO-treated plants of all genotypes could be due, at least partly, to impaired meristem formation in root tissue. Interestingly, the nodule number did not differ between untreated and BSO+GSH-treated plants for all genotypes, except sym33-3 (Supplementary Table 4). This implies that additional factors may regulate nodule number in sym33-3 plants. For instance, the synthesis of salicylic acid (SA), a negative regulator of nodulation (Sun et al., 2006; Ding et al., 2008; Tsyganova and Tsyganov, 2018), could be increased in nodules of the sym33-3 mutant with the manifestation of defense responses. Indirect evidence for this possibility was provided by the high expression levels of the SA-induced gene PR1 in untreated and BSO+GSH-treated sym33-3 plants relative to other genotypes (Figure 7). That the GSH and hGSH levels in the roots with nodules of BSO+GSH-treated sym33-3 plants amounted to only 38 and 18% of those of untreated plants indicates that a minimal GSH level is essential for meristem functioning; however, the levels recorded in this mutant were insufficient to restore nodule numbers. 2ff7e9595c
