- We demonstrate the modulation of coherent acoustic phonons (CAPs) and their response to high excitation densities in AlGaN/GaN heterostructures under ultrafast near-band gap optical excitation. Displacively excited CAPs induce a strain-modulated piezoelectric field, modulating the transmission of the probe beam through the bulk Franz-Keldysh effect, and manifest as a phase flip when photon energy approaches the intrinsic bandgap. A large initial amplitude of CAP is observed in GaN, followed by a rapid decay arising from screening by the piezoelectric field. In the AlGaN/GaN heterostructure, the top strained layers enhance CAP-piezoelectric coupling. Additionally, the higher thermal conductivity of the top layers and the intrinsic nature of the GaN layer in the heterostructure play a significant role in maintaining phonon coherence due to reduced phonon-phonon scattering and phonon-impurity scattering, respectively. The excited acoustic phonons are long-lived, with high amplitude, exhibiting cosinusoidal displacive behavior that persists due to the interplay between strain waves, piezoelectric field modulation, deformation potential coupling, and thermoelastic expansion. Observed phonon frequencies between 40 and 80 GHz are governed by the acoustic transit time and pump wavelength. We also observe Brillouin frequency components in the range 100-120 GHz, with a significantly long decay time. Furthermore, inhomogeneous plasma distribution modifies the phonon frequency and induces coupled phonon oscillations, which are observed as a beating pattern with frequency content in the sub-THz and THz regimes. These experimental conditions are analogous to high-field transport under electrical injection, where the carrier excitation mechanism differs but the energy release to the phonon subsystem resembles that under optical excitation. This work presents a pathway for the development of on-demand coherent phonon sources without a superlattice structure, thereby opening up the possibility of understanding plasmon-phonon interactions in AlGaN/GaN heterostructures for solid-state applications. - Source: PubMed

Bhat Shazan AhmadGanguly SwaroopSaha Dipankar - DNA methylation is a key regulator of tissue-specific gene expression, cell differentiation, and development. In mammals, DNA methylation predominantly occurs as 5-methylcytosine (5mC) at CpG dinucleotides. DNA methylation is a dynamic and reversible process. Increasing evidence indicates that 5-hydroxymethylcytosine (5hmC), an oxidation product of 5mC, plays important roles in chromatin organization and gene regulation. Aberrant 5hmC levels have been associated with various neurological disorders and cancer types. Despite its biological relevance, accurate quantification of 5hmC at single-CpG resolution remains challenging due to its low abundance and methodological limitations of existing detection approaches. - Source: PubMed

- Stem lodging poses a major challenge to modern maize production by significantly reducing yield, impairing grain quality, and complicating mechanical harvest. Our previous work identified ZmmiR528 as a key post-transcriptional regulator of lignin biosynthesis and lodging resistance, highlighting its potential as a breeding target. However, strategies to leverage this gene in breeding programs have remained unexplored. In this study, we characterized stem lodging resistance in a diverse panel of 263 maize accessions under field conditions and performed sequencing of the and loci. An association analysis identified a single-nucleotide polymorphism (SNP) in the promoter that was significantly correlated with the stem lodging resistance index. Accessions carrying the -C allele at this locus demonstrated a significantly higher stem lodging resistance index and greater stem lignin content than those with the -T allele. Luciferase assays indicated that the -C haplotype conferred lower transcriptional activity than the Pro-T haplotype. Consistent with this, stem-loop RT-qPCR revealed that mature ZmmiR528 abundance was significantly lower in accessions harboring the -C allele. We subsequently developed a cleaved amplified polymorphic sequence (CAPS) marker based on this SNP and validated its efficacy in a panel of ten diverse inbred lines. Collectively, our findings identify a novel functional promoter allele that enhances lodging resistance by repressing ZmmiR528 expression, thereby providing a validated molecular tool for breeding lodging-resistant maize. - Source: PubMed
