TOR-dependent regulation of the yeast homolog of the juvenile Batten Disease-associated gene <i>CLN3</i>

TOR-dependent regulation of the yeast homolog of the juvenile Batten Disease-associated gene CLN3

Vijaykumar Pillalamarri1, Samuel W.M. Gatesy1, Amanda E. Grassel1, Lucienna Wolf1, Justin P. Whalley2 and David M. Mueller1,*

This study identifies conditions and genes that induce BTN1 expression in yeast. We show that BTN1 expression is regulated by translational control and by the mTOR1 pathway. An understanding of when and why BTN1 expression will aid in understanding the expression of CLN3, which may be helpful in the treatment of this devastating disease.

VapA/Scs2 sustains polarized growth in <i>Aspergillus nidulans</i> by maintaining AP-2-mediated apical endocytosis

VapA/Scs2 sustains polarized growth in Aspergillus nidulans by maintaining AP-2-mediated apical endocytosis

Xenia Georgiou1, Sofia Politi1, Sotiris Amillis1 and George Diallinas1,2,*

To explore the functional significance of ER–PM contact sites in filamentous fungi, we identified and genetically characterized all Aspergillus nidulans proteins homologous to Snc2/VAP, Ist2, or tricalbins.

Genetic make-up and regulation of the L-lysine biosynthesis pathway in <i>Vibrio natriegens</i>

Genetic make-up and regulation of the L-lysine biosynthesis pathway in Vibrio natriegens

Elly Straube1, Johannes Radde1, Thi Van Anh Tran1, Negin Keihani Yazdi1, Rubén Crespo Blanco1, Ha Thanh Le2, Cláudio J.R. Frazão1 and Thomas Walther1,*

This study analysed the make-up and regulation of the biosynthetic pathway for L-lysine and related L-aspartate family amino acids (AFAAs) in Vibrio natriegens DSM759 to provide a comprehensive basis for future metabolic engineering endeavours aiming at developing this strain into an amino acid overproducer.

Regulation of extracellular vesicles for protein secretion in <i>Aspergillus nidulans</i>

Regulation of extracellular vesicles for protein secretion in Aspergillus nidulans

Rebekkah E. Pope1, Patrick Ballmann2, Lisa Whitworth3 and Rolf A. Prade1,*

This study reveals that Aspergillus nidulans boosts extracellular vesicle production when ER-trafficked enzymes are induced, uncovering how fungi remodel their secretome through vesicle-mediated secretion to adapt to changing environments and biofilm formation.

Transcriptomic response to different heme sources in <i>Trypanosoma cruzi</i> epimastigotes

Transcriptomic response to different heme sources in Trypanosoma cruzi epimastigotes

Evelyn Tevere1,a, María G. Mediavilla1,a, Cecilia B. Di Capua1, Marcelo L. Merli1, Carlos Robello2,3, Luisa Berná2,4 and Julia A. Cricco

This study uncovers how the Chagas disease parasite adapts to changes in heme, an essential molecule for its survival, providing transcriptional clues to heme metabolism and identifying a previously unreported heme-binding protein in T. cruzi.

Sir2 regulates selective autophagy in stationary-phase yeast cells

Ji-In Ryua, Juhye Junga, and Jeong-Yoon Kim

This study establishes Sir2 as a previously unrecognized regulator of selective autophagy during the stationary phase and highlight how cells dynamically control organelle degradation.

Luminal acetylation of microtubules is not essential for <i>Plasmodium berghei</i> and <i>Toxoplasma gondii</i> survival

Luminal acetylation of microtubules is not essential for Plasmodium berghei and Toxoplasma gondii survival

Thrishla Kumar1,a, Katharina Röver2,a, Johannes F. Stortz3,a, Annika M. Binder2,a, Benjamin Spreng2, Madlen Konert2, Markus Meissner1, Friedrich Frischknecht2,4 and Elena Jimenez-Ruiz1,*

Acetylation of α-tubulin at lysine 40 is not essential for cytoskeletal stability in Plasmodium berghei or Toxoplasma gondii, suggesting redundancy and plasticity in microtubule regulation in these parasites.
