The disaccharide Suc cannot be utilized directly; rather, it is irreversibly hydrolyzed by invertase to the hexoses Glc and Fru to shape plant growth. In this context, Glc controls the stability of the transcription factor Ethylene-Insensitive3 (EIN3) via the function of Hexokinase1 (HXK1), a Glc sensor. Thus, invertase, especially the major neutral cytosolic invertase (CINV), constitutes a key...

Tropical shrimp, like Litopenaeus vannamei, in land‐based recirculating aquaculture systems (RAS) are often kept at low water salinities to reduce costs for artificial sea salt and the amount of salty wastewater. Although these shrimp are tolerant against low salinities, innate immunity suppression and changes in the microbial composition in the water can occur. As especially Vibrio spp. are...

by Linlin Zhao, Sarah Richards, Franziska Turck, Markus Kollmann In order to successfully reproduce, plants must sense changes in their environment and flower at the correct time. Many plants utilize day length and vernalization, a mechanism for verifying that winter has occurred, to determine when to flower. Our study used available temperature and day length data from different climates to...

Botrytis rot is a serious disease of fruit and vegetables around the globe. We tested and found that frequencies above 5 kHz and mechanical vibrations and acoustic frequencies from cold‐storage devices increase the growth rate of botrytis rot, suggesting that acoustic output from storage units could promote the mold during transport, storage, or within grocery stores. Results open new...

BACKGROUND During the production of fresh‐cut products, crops are exposed to wounding stress, and as a stress response, phenolic antioxidants are synthesized. This stress response is elicited by extracellular adenosine triphosphate, released from wounded cells and recognized by receptors of unwounded cells. The phenolic antioxidants produced as a stress response are beneficial for human health....

Postharvest losses of whole and fresh‐cut fruits and vegetables cause significant reductions in food availability and an increase in economic losses/damages. Additionally, regulatory agencies are increasingly restricting the postharvest use of synthetic chemicals. This has strengthened the need to develop environmentally friendly approaches to postharvest management, such as utilization of...

by Akshit Puri, Kiran Preet Padda, Chris P. Chanway Lodgepole pine, a prominent Pinaceae tree species native to western North America, is well-known for its ability to thrive in highly disturbed and degraded areas. One such area is the Sub-Boreal Pine-Spruce xeric-cold (SBPSxc) region in British Columbia, Canada, which is characterized by weakly-developed, parched soils that lack an organic...

Ethylene is the key regulator of sex determination in monoecious species of the family Cucurbitaceae. This hormone determines which individual floral meristems develop as female or male flowers and the female flowering transition. The sex determination genes discovered so far code for ethylene biosynthesis enzymes, but little is known about the importance of ethylene signaling components. In this...

Fruit crops are subject to precocious fruit abscission, during which the phytohormone ethylene (ET) acts as a major positive regulator. However, the molecular basis of ET‐induced fruit abscission remains poorly understood. Here, we show that two ETHYLENE INSENSITIVE 3‐like (EIL) homologs in litchi, LcEIL2 and LcEIL3, play a role in ET‐activated fruitlet abscission. LcEIL2/3 were significantly...

There are many critical challenges in the use of primary and secondary cultures and their biological compounds in food commodities. An alternative is the application of postbiotics from the starter and protective lactic acid bacteria (LAB). The concept of postbiotics is relatively new and there is still not a recognized definition for this term. The word “postbiotics” is currently used to refer...

Peaches are vulnerable to cold temperature, showing the symptoms of chilling injury (CI). The occurrence of CI results in irreversible aroma loss, especially ‘peach‐like’ lactones loss during cold storage and subsequent shelf life. Methyl jasmonate (MeJA) treatment is effective in alleviating CI symptoms in peach fruit; however, its effect on peach aroma volatiles is still unknown. To explore the...
