  1. Research has primarily focused on understanding the perspectives and experiences of US based crowdworkers, leaving a notable gap to those within the Global South. To bridge this, we conducted a survey with 100 crowdworkers across 16 Latin American and Caribbean countries. To understand the tensions between the crowdworking economy abroad. In our study we found crowd work being the stepping stone to financial and professional independence among those we surveyed along with the tensions within data extraction among crowdworkers.

  2. Abstract In plants, light-dependent activation of de novo fatty acid synthesis (FAS) is partially mediated by acetyl-CoA carboxylase (ACCase), the first committed step for this pathway. However, it is not fully understood how plants control light-dependent FAS regulation to meet the cellular demand for acyl chains. We report here the identification of a gene family encoding for three small plastidial proteins of the envelope membrane that interact with the α-carboxyltransferase (α-CT) subunit of ACCase and participate in an original mechanism restraining FAS in the light. Light enhances the interaction between carboxyltransferase interactors (CTIs) and α-CT, which in turn attenuates carbon flux into FAS. Knockouts for CTI exhibit higher rates of FAS and marked increase in absolute triacylglycerol levels in leaves, more than 4-fold higher than in wild-type plants. Furthermore, WRINKLED1, a master transcriptional regulator of FAS, positively regulatesCTI1expression by direct binding to its promoter. This study reveals that in addition to light-dependent activation, “envelope docking” of ACCase permits fine-tuning of fatty acid supply during the plant life cycle.
