TaANT11‐4A enhances grain yield by orchestrating photosynthesis and carbohydrate metabolism through direct transcriptional activation

Journal of Integrative Plant Biology, EarlyView.
TaANT11‐4A is a positive regulator of wheat grain size and yield, directly activating TaEGY2, TaAAE1, and TaAAE2 to enhance photosynthesis and carbohydrate metabolism. The favorable Hap2 haplotype increases TaANT11‐4A expression and grain size, providing a genetic resource for breeding higher‐yielding wheat varieties.

Total peptide spectral counts from photosystem complex subunits.

, 2013
Spectral counts result from quadruplicate analyses on Fe-replete (blue) and Fe-limited (red) cultures. Photosystem II requires 2–3 atoms of Fe per complex, Cytochrome (Cyt) b6f complex requires 6 Fe atoms per complex, and photosystem I requires 12 Fe ...

Near‐infrared confocal imaging reveals the spatial organisation of far‐red photosynthesis in Shark Bay microbial mats and Halomicronema sp.

Journal of Microscopy, EarlyView.
Abstract Far‐red light (FRL) cyanobacteria occupy spectrally filtered habitats where visible wavelengths are depleted but far‐red radiation persists. Shark Bay (Western Australia) stromatolitic microbial mats provide such a habitat, containing subsurface cyanobacterial communities in which chlorophyll d/f (Chl d/f)‐containing phototrophs coexist with ...

Photosystem I Reduction in Diatoms: As Complex as the Green Lineage Systems but Less Efficient

, 2016
Diatoms occupy a key branch in the evolutionary tree of oxygen-evolving photosynthetic organisms. Here, the electron transfer reaction mechanism from cytochrome c6 to photosystem I from the diatom Phaeodactylum tricornutum has been analyzed by laser ...

Comprehensive revision of Mallomonas sect. Peroneides stat. nov. (Chrysophyceae) integrating morphology and multigene phylogeny

Journal of Phycology, EarlyView.
Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

Nitric Oxide Alleviates Low-Light-Induced Photosynthetic Impairment by Improving Photosystem Coordination and Electron Transport in Tomato Seedlings

Plants
Low light is a major environmental constraint that limits crop productivity by restricting photosynthetic carbon assimilation and disrupting photosynthetic function. Nitric oxide (NO) is an important signaling molecule involved in plant stress responses;

Lhca5 interaction with plant photosystem I

, 2006
In the outer antenna (LHCI) of higher plant photosystem I (PSI) four abundantly expressed light-harvesting protein of photosystem I (Lhca)-type proteins are organized in two heterodimeric domains (Lhca1/Lhca4 and Lhca2/Lhca3).

Finding the sweet spot: An exploration of environmental factors to optimize Ulva carbohydrate content and composition

Journal of Phycology, EarlyView.
Abstract Green macroalgae from the Ulva genus are rich in polysaccharides of interest, including ulvan, starch, and cellulose. However, their content and structure are impacted by environmental factors, which poses challenges for industrial applications, especially in the context of climate change.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...
