OTS1 and OTS2 SUMO proteases link plant development and survival under salt stress
No full textHigh salinity is an important factor limiting agriculture as major crops are salt sensitive. Understanding salt stress signalling is key to producing salt tolerant crops. The small ubiquitin-like modifier (SUMO) is a crucial regulator of signalling proteins in eukaryotes. Attachment of SUMO onto substrates is reversible and SUMO-proteases which specifically cleave the SUMO-substrate linkages play a vital regulatory role during SUMOylation. We have identified two SUMO proteases OTS1 and OTS2 that act redundantly to regulate salt stress responses in Arabidopsis. ots1 ots2 double mutants show extreme sensitivity to salt. However during non-salt conditions, ots1 ots2 double mutants are phenotypically similar to wild-type plants in terms of growth and development. Overexpressing SUMO1 in the ots1 ots2 double mutants severally diminishes plant size as quantified by rosette diameter even under non-stressed conditions. This reduction in plant growth is reminiscent of ots1 ots2 double mutants under salt stress. Our data indicates that overSUMOylation of target proteins can have severe effects on plant growth and that SUMO proteases like OTS1/2 are key to maintaining cellular balance of SUMOylation. We propose that upon environmental stress the hyperSUMOylation of key target proteins act to retard growth to survive stress periods. Addendum to: Conti L, Price G, O'Donnell E, Schwessinger B, Dominy P, Sadanandom A. Small ubiquitin-like modifier proteases OVERLY TOLERANT TO SALT1 and -2 regulate salt stress responses in Arabidopsis

Plastics recycling and sampling
No full textThis is the author accepted manuscript. The final version is available from AusIMM via the link in this record.This contribution examines the effect of feedstock sampling before the sorting stage of PET bottle recycling. Batches of waste PET bottles may contain non-PET bottles which need to be removed by sorting. Any residual presence of PVC is detrimental for the quality of products manufactured from recycled PET. The maximum tolerated concentration of PVC in
cleaned PET is extremely low, which places high demands on the recovery of PVC achieved by sorting. To be confident of attaining the desired PET quality after sorting, acceptance sampling of truckloads of PET bottles may take place prior to sorting. It is shown that accounting for sampling uncertainty requires that the sorting process achieves a consistently
high recovery of PVC bottles
