The multidimensional regulation roles and mechanisms of calcium in fruit quality

Journal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

Reducing the Sinapine Levels of Camelina sativa Seeds Through Targeted Genome Editing of REF1. [PDF]

Plant Biotechnol J
ABSTRACT Sinapine (O‐sinapoyl choline) is the major phenolic metabolite typically found in the oil‐rich seeds of Brassicaceae such as Camelina sativa and Brassica napus. It imparts a bitter taste to the seeds as a defence mechanism against herbivores, but it also renders them less palatable to livestock.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Key amino acid residues govern the substrate selectivity of the transporter Xltr1p from Trichoderma reesei for glucose, mannose, and galactose

Engineering Microbiology
This research identified four amino acid residues (Leu174, Asn297, Tyr301, and Gln291) that contribute to substrate recognition by the high-affinity glucose transporter Xltr1p from Trichoderma reesei.

Reduced snow cover at the alpine treeline: resistance and recovery of saplings

New Phytologist, EarlyView.
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco

Plant Biotechnology Journal, EarlyView.
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

Rewiring Steroidal Metabolic Pathways for Diosgenin Production in Solanum nigrum

Plant Biotechnology Journal, EarlyView.
ABSTRACT Diosgenin is a key starting material for the synthesis of steroidal drugs, such as corticosteroids and sex hormones. While the primary commercial source of diosgenin is the tubers of Dioscorea spp., identifying alternative plant hosts capable of diosgenin biosynthesis could enhance its production.
