(Submitter supplied) Plant resistance inducers (PRIs) and nitrogen (N) nutrition are both factors known to act on plant defence but their interaction has been little studied and needs further research. The objective of the study was to further characterize this interaction on apple (Malus domestica) plantlets at the molecular level. The produced dataset allows the investigation of the molecular mechanisms underlying: i) the biotic resistance induced by ASM treatments on apple seedlings, ii) their response to different nitrogen (N) status (N limitation or subsequent N resupply), iii) the combination of both N status and ASM treatment.

(Submitter supplied) To preserve quality feature and ensuring availability of fresh fruit on the market, apples need to be stored. The low temperature applied during storage, beside avoiding important fruit loss, can also promote the development of serious chilling injury type of disorder, such as superficial scald. One of the strategies largely employed to prevent the development of this phenomenon is the control of the storage atmosphere, by lowering down the concentration of oxygen. more...

(Submitter supplied) EGCG, as an active oxygen scavenger, has a significant effect on inhibiting the greasiness of apples. However, the impact of greasiness on fruit storage and how EGCG eliminates this effect, as well as its influence on apple quality formation, have not been clarified. In this study, we found that exogenous application of EGCG effectively improved a series of nutritional growth indicators, including seedling growth status and photosynthetic activity. more...

(Submitter supplied) Plant-based diets could be a key source of microRNAs in animals. Plant microRNAs are cross-kingdom gene expression regulators that could modulate mammalian gene expression, influencing their physiology. Therefore, it is important to identify the microRNA expression profile of plant foods in order to identify potential target genes and biological functions in the mammalian host. Next-generation sequencing was applied to identify microRNAs in RNA samples derived from nuts (walnut and almond), vegetables (spinach) and fruits (orange, apple, olive, pear, and tomato). more...

(Submitter supplied) The low temperature normally applied to prevent fruit decay during the storage of apples, can also triggers the onset of a chilling injury disorder known as superficial scald. In this work, the etiology of this disorder and the mechanism of action of two preventing strategies, such as the application of 1-MCP and storage at low oxygen concentration in ‘Granny Smith’ and ‘Ladina’ apple cultivars was investigated. more...

(Submitter supplied) MicroRNA172 (miR172) plays a role in regulating a diverse range of plant developmental processes. However, its role in regulating anthocyanin biosynthesis is unclear. In this study, we show that transgenic apple plants over-expressing miR172 show a reduction in red colouration and anthocyanin accumulation in multiple tissue types. This reduction was consistent with decreased expression of APETALA2 homolog MdAP2_1a (a miR172 target gene), MdMYB10, and targets of MdMYB10, as demonstrated by both RNA-seq and RT-PCR analyses. more...

(Submitter supplied) Apple seeds were subjected to accelerated aging. After 7, 14, and 21 days of aging, embryos were isolated. Part of the embryos were shortly fumigated with nitric oxide (NO). After 48 h of embryos culture (aged embryos or aged embryos treated with NO), embryonic axes were used to extract the total RNA. RT-qPCR were done to analyze the changes in the expression of genes related to seed aging. Short-term (3 h) treatment of embryos isolated from accelerated aged apple seeds (Malus domestica Borkh.) with NO partially reduced the effects of aging. more...
