“…ACC deaminases convert ACC in α-ketobutyrate and ammonia 70,71 , lowering ethylene levels in the plant 32 . Reduced ethylene levels can delay senescence 72 and improve plant resistance to stressful environments 73 and pathogen attacks 74 . Hence, the presence of acdS could also be favored by selection in intensive agriculture systems where plants are often under reduced stress.…”

The plant seed-borne microbiome comprises microorganisms vertically inherited from the mother plant. This microbiome is often linked to early-life protection and seedling growth promotion. Here, we compare the seed-borne bacteriomes of a commercial hybrid and a landrace maize variety. The landrace variety displays a more diverse seed-borne microbiome, featuring a variety of taxa across samples. In contrast, the microbiome of the hybrid variety is less diverse and more uniform across samples. Although both microbiomes lack a functional nitrogen fixation apparatus, we found a remarkably distinct presence of genes associated with phytohormone production and phosphate solubilization, particularly in the landrace variety. In addition, we recovered 18 metagenome-assembled genomes (MAGs), including four from potentially novel species. Collectively, our results allow a better understanding of the contrasting diversity between maize varieties and open important perspectives for designing synthetic microbial communities for agroecosystems.

“…The release of ethylene gas in fruits and vegetables causes them to ripen and undergo physical, chemical and biological changing, such as changes in the appearance in terms of shape and colour, changes in firmness and texture, changes in chemical composition which related to the taste and changes in nutritional value. It also facilitates the growth of microorganisms that leads to fruit spoilage 4–6 . Some evidence shows that a very low concentration of ethylene (approximately 20 ppm) is enough for initial ripening process of climacteric fruit, that is, banana, mango and tomato 7 …”

Ethylene is a type of gas that fruits and vegetables can produce naturally. The release of ethylene gas from fruits and vegetables causes them to ripen and undergo physical, chemical and biological changes, such as changes in the appearance in terms of shape and colour, changes in firmness and texture, changes in taste and changes in nutritional value. Furthermore, it also facilitates the growth of microorganisms. These changes lead to spoilage if the fruit or vegetables are left to over ripen. Therefore, the prevention and reduction of damage caused by the ripening of fruits and vegetables entail reducing or slowing down the release of ethylene gas produced by them. This research project aimed to study the properties of activated carbon and potassium permanganate (KMnO4) modified activated carbon, applied as a printing layer on plastic materials for bananas, in terms of their adsorption and decomposition of ethylene. Active and water‐based flexography printing inks were prepared from water‐based binder and ethylene adsorbing and scavenging agents (activated carbon and KMnO4 modified activated carbon) at various concentrations of active agents, that is, 0.0, 5.0, 7.5 and 10.0%w/v. Then, those inks were printed on polypropylene plastic substrate. The delayed ripening of fruits results showed that the plastic materials coated with modified activated carbon inks delayed the physiology disorder (colour and firmness changing about 250% and 226%) and prolonged the storage time up to 14 days when compared with control. In addition, the functional ink layer also presented a high efficiency of abrasion resistance of about 75 cycles of rubbing at 1.8 kg. The products that stem from this research can be applied as packaging for fruits and vegetables in the form of bags, stickers and product pads that can help extend the life and slow the ripening of fruits and vegetables.

“…The responses of harvested fruits, vegetables, and ornamental crops to endogenously produced and exogenously applied ethylene are numerous and varied, and they can be beneficial or detrimental depending on each case (Saltveit, 1999). In general, ethylene can influence the postharvest life of both climacteric and non climacteric fruit by affecting their quality attributes and the development of physiological disorders and postharvest diseases (Kader, 1985). Effects of ethylene on fruit external appearance, texture, flavor, and nutritive value have been extensively reviewed by different authors.…”

Ethylene as a Postharvest “Evil” and its Remedies in some Horticultural Crops

Postharvest is an agricultural operation starting from the time of harvesting till the commodity reaches to the ultimate user/consumer. The postharvest life of horticultural produces is different from other produces in having shortest shelf life. In some horticultural crops which we call climacteric, there is an increase rate of respiration mainly due to a very high synthesis of the ripening hormone (ethylene), which has both beneficial and detrimental ("evil") effects depending on the type of commodity. The effect of ethylene is accumulative so continuous exposure to a low concentration of ethylene throughout marketing can cause significant harm. In climacteric fruits exogenous C2H4 caused the peel and flesh to ripen out of phase, with the flesh ripening faster than the peel. In a study of cut flowers, exposure to ethylene at 100 µl l -1 reduced vase life by about 30%. In order to minimize this evil effect different vase solutions have been investigated. STS (silver thiosulfate) and 1-MCP (1-methylcyclopropene) can effectively protect flowers against exogenous ethylene. Pre-treatment of plants with 1 µl l -1 1-MCP for 2 h completely inhibited ethylene-induced petal abscission. Applications of Silver thiosulphate (STS) and 1-MCP have a great role to withstand the impact of ethylene. Thus they give relief for those concerned with horticultural crops which are sensitive to ethylene action. However more researches have to be done about the level and time of application of these chemicals and a new chemical against ethylene should be investigated.
