Hydroponic food production in greenhouses is challenged by reduced exposure to ultraviolet (UV) light and beneficial soil microorganisms, which predisposes plants to antioxidant deficiencies and disease susceptibility. The objective of this study was to investigate the effects of UV light exposure and compost tea treatment on hydroponically grown plants. Garnet Giant mustard greens were hydroponically grown in both indoor and outdoor greenhouse settings, with and without UV light blocking and supplementation of compost tea. Plants grown outside in greenhouses produced more dry mass than those grown indoors. Compost tea supplementation boosted nitrogen and mineral accumulations in the absence of UV-blocking. Increased UV exposure resulted in more red pigmentation and higher antioxidant activities of the mustard greens, while compost tea supplementation reduced antioxidant activities. Compost tea treatment increased beneficial bacteria and decreased fungal pathogens. Overall, exposure to UV radiation and beneficial microorganisms improved the performance and nutrient profile of the mustard greens.

“…The genus Leptolyngbya , a filamentous cyanobacteria, is widely distributed in surface soil, freshwater, brackish water, and seawater, and is well adapted to low-inorganic-carbon environments [ 18 ]. In addition, Leptolyngbya has a wide range of uses such as alloprotein production [ 19 ], biological nitrogen fixation [ 20 ], green manure and nutrient regulator for rice fields [ 21 ], and the removal of heavy metals from water bodies [ 22 ]. It is worth noting that Leptolyngbya also has a high-affinity and high-capacity CCM, which may help it to better adapt to intense white light irradiation to avoid phototoxicity, suggesting that Leptolyngbya ’s CCM has novel properties [ 23 ].…”

Cyanobacteria, one of the most widespread photoautotrophic microorganisms on Earth, have evolved an inorganic CO2-concentrating mechanism (CCM) to adapt to a variety of habitats, especially in CO2-limited environments. Leptolyngbya boryana, a filamentous cyanobacterium, is widespread in a variety of environments and is well adapted to low-inorganic-carbon environments. However, little is currently known about the CCM of L. boryana, in particular its efficient carbon fixation module. In this study, we isolated and purified the cyanobacterium CZ1 from the Xin’anjiang River basin and identified it as L. boryana by 16S rRNA sequencing. Genome analysis revealed that L. boryana CZ1 contains β-carboxysome shell proteins and form 1B of Rubisco, which is classify it as belonging to the β-cyanobacteria. Further analysis revealed that L. boryana CZ1 employs a fine CCM involving two CO2 uptake systems NDH-13 and NDH-14, three HCO3− transporters (SbtA, BicA, and BCT1), and two carboxysomal carbonic anhydrases. Notably, we found that NDH-13 and NDH-14 are located close to each other in the L. boryana CZ1 genome and are back-to-back with the ccm operon, which is a novel gene arrangement. In addition, L. boryana CZ1 encodes two high-affinity Na+/HCO3− symporters (SbtA1 and SbtA2), three low-affinity Na+-dependent HCO3− transporters (BicA1, BicA2, and BicA3), and a BCT1; it is rare for a single strain to encode all three bicarbonate transporters in such large numbers. Interestingly, L. boryana CZ1 also uniquely encodes two active carbonic anhydrases, CcaA1 and CcaA2, which are also rare. Taken together, all these results indicated that L. boryana CZ1 is more efficient at CO2 fixation. Moreover, compared with the reported CCM gene arrangement of cyanobacteria, the CCM-related gene distribution pattern of L. boryana CZ1 was completely different, indicating a novel gene organization structure. These results can enrich our understanding of the CCM-related gene arrangement of cyanobacteria, and provide data support for the subsequent improvement and increase in biomass through cyanobacterial photosynthesis.
