Plant Direct, Volume 9, Issue 5, May 2025.ABSTRACT Iron–sulfur clusters are involved in many biological processes, including photosynthetic electron transport in the chloroplast and respiratory electron transport in the mitochondrion. Iron–sulfur cluster biosynthesis requires iron–sulfur carriers such as nitrogen‐fixation‐subunit‐U [NFU]‐type proteins.

Chromosome Segregation in Closed Mitosis Under an Excess of Nuclear Envelope
Biology of the Cell, Volume 117, Issue 5, May 2025.This study investigated the impact of Nem1‐Spo7/lipin‐mediated nuclear envelope (NE) size regulation during closed mitosis in Saccharomyces cerevisiae. Nem1 depletion resulted in persistent chromatin protrusions, particularly at the rDNA locus, leading to lagging chromosome XII's right arm sisters during late anaphase.

Journal of Time Series Analysis, Volume 46, Issue 3, Page 582-595, May 2025.Estimating parameters of functional ARMA, GARCH and invertible processes requires estimating lagged covariance and cross‐covariance operators of Cartesian product Hilbert space‐valued processes. Asymptotic results have been derived in recent years, either less generally or under a strict condition.
