Regulation of Leaf Senescence by Cytokinin, Sugars, and Light. Effects on NADH-Dependent Hydroxypyruvate Reductase [PDF]

open access: yes, 1998
The aim of this study was to investigate the interactions between cytokinin, sugar repression, and light in the senescence-related decline in photosynthetic enzymes of leaves. In transgenic tobacco (Nicotiana tabacum) plants that induce the production of

Coexistence of Wolbachia with Buchnera aphidicola and a secondary symbiont in the aphid Cinara cedri.

open access: yes, 2004
Intracellular symbiosis is very common in the insect world. For the aphid Cinara cedri, we have identified by electron microscopy three symbiotic bacteria that can be characterized by their different sizes, morphologies, and electrodensities.

A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant

open access: yesNew Phytologist, EarlyView.
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of

Discrete and cell‐specific hypoxic responses in Arabidopsis roots resolved by single‐nuclei transcriptomics

open access: yesNew Phytologist, EarlyView.
Summary With the intensification of unpredictable flooding events because of global warming, there is a need to understand how root cells perceive and respond to oxygen deprivation. The use of high‐throughput single‐nuclei RNA‐sequencing (snRNA‐Seq) allows the examination of gene expression profiles in discrete cell types.

Optimization of carbon and nitrogen utilization for enhanced photosynthesis, biomass and yield by coexpression of phosphoenolpyruvate carboxylase, aspartate aminotransferase and glutamine synthetase in Brassica juncea

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Coexpression of genes involved in carbon (C) and nitrogen (N) metabolism offers a promising avenue for improving crop yield. This study investigated the impact of coexpressing phosphoenolpyruvate carboxylase [ZmPEPC (P)], aspartate aminotransferase [GmAspAT (A)] and glutamine synthetase [NtGS (G)] in Brassica juncea to enhance plant yield ...

Calmodulin‐Like Protein MfCML50 Interacts With Carveol Dehydrogenase in Medicago falcata to Regulate Cold Tolerance Through Mediating ROS Homeostasis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Low temperature triggers Ca2+ signalling and reprogramming of gene expression and metabolism in plants. However, how the Ca2+ signal is transduced to the downstream metabolic pathways remains unknown. The involvement of a cold‐induced calmodulin‐like protein, MfCML50, from Medicago falcata in regulation of cold tolerance was examined in the ...

ZmmiR1432‐ZmCML21‐ZmPMA2 Module Affects Maize Low Phosphate Tolerance via Regulating Organic Acid Secretion

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Phosphorus is indispensable in agricultural production. The growing global demand for food necessitates the development of crops with enhanced phosphorus utilisation efficiency. However, the molecular mechanisms coordinating phosphorus utilisation efficiency in plants remain incompletely characterised.

ZmTH1 Is Vital for Healthy Plant Growth and Promotes Cold/Drought Tolerance by Regulating Thiamin Diphosphate‐Dependent Metabolisms in Maize

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Vitamin B1 (VB1) plays a crucial role in sustaining plant health and enabling adaptive responses to environmental stress. The complex maize genome implies a sophisticated VB1 synthesis pathway, with the mechanisms by which VB1 benefits plants remaining elusive.
