Anion‐Selective Channels Formed by Synthetic 13‐Mer Chimeric α ‐Peptide‐Oligourea Foldamers

Chiranjit Dutta, Dandan Su, Pannaga Krishnamurthy, Zhaoxing Li et autres

ABSTRACT Attempts to design transmembrane channels with selective transport properties using advanced chemistry and computational tools have had limited success. Previously, we characterized 15‐mer α‐peptide‐oligourea chimeric foldamers that form anion channels with high Cl − selectivity. Here, we report the design and …

Innovative Self‐Assembly of 15‐Mer Chimeric α‐Peptide–Oligourea Foldamers toward Cl−‐Selective Ion Channels

Chiranjit Dutta, Pannaga Krishnamurthy, Dandan Su, Jianwei Li et autres

Constructing artificial ion channels is a challenging task. Herein, the de novo design of transmembrane ion channels made up of amphiphilic peptide–oligourea chimeric helices is described. They consist of an oligourea segment (7‐mer) attached to the C‐terminus of a short peptide (8‐mer). …

The translocation of a chloride channel from the Golgi to the plasma membrane helps plants adapt to salt stress

Sivamathini Rajappa, Pannaga Krishnamurthy, Hua Huang, Dejie Yu et autres

Abstract A key mechanism employed by plants to adapt to salinity stress involves maintaining ion homeostasis via the actions of ion transporters. While the function of cation transporters in maintaining ion homeostasis in plants has been extensively studied, little is known about …

All-organic transparent plant e-skin for noninvasive phenotyping

Yanqin Yang, Tianyiyi He, Pratibha Ravindran, Feng Wen et autres

Real-time in situ monitoring of plant physiology is essential for establishing a phenotyping platform for precision agriculture. A key enabler for this monitoring is a device that can be noninvasively attached to plants and transduce their physiological status into digital data. Here, …

WRKY9 transcription factor regulates cytochrome P450 genes CYP94B3 and CYP86B1 , leading to increased root suberin and salt tolerance in Arabidopsis

Pannaga Krishnamurthy, Bhushan Vishal, Amrit Bhal, Prakash P. Kumar

Abstract Salinity affects crop productivity worldwide and mangroves growing under high salinity exhibit adaptations such as enhanced root apoplastic barrier to survive under such conditions. We have identified two cytochrome P450 family genes, AoCYP94B3 and AoCYP86B1 from the mangrove tree Avicennia officinalis …

Functional characterization and expression profiling of glyoxalase III genes in date palm grown under abiotic stresses

Gerry Aplang Jana, Pannaga Krishnamurthy, Prakash P. Kumar, Mahmoud W. Yaish

Methylglyoxal (MG), a by-product of various metabolic processes, including glycolysis, is a highly reactive cytotoxic metabolite. The level of MG in the cell is maintained at a non-toxic level via MG detoxification pathways such as the universal glyoxalase system, including glyoxalase I/II/III …
