Chlorophyll (CHL) is present in many plant organs, and its metabolism is strongly regulated throughout plant development. Understanding the fate of CHL in senescent leaves or during fruit ripening is a complex process. The stay-green (SGR) protein has been shown to affect CHL degradation. In this study, we used the conserved sequences of STAY-GREEN domain protein (NP_567673) in Arabidopsis thal...

Iron (Fe) deficiency in plants limits crop growth and productivity. Molecular mechanisms that plants use to sense and respond to Fe deficiency by coordinated expression of Fe-uptake genes are not fully understood. The C940-fe chlorotic melon (Cucumis melo) mutant known as fefe is unable to upregulate Fe-uptake genes, however, the FeFe gene had not been identified. In this study, we used two F2 ...

Iron (Fe) is an essential mineral that has low solubility in alkaline soils, where its deficiency results in chlorosis. Whether low Fe supply and alkaline pH stress are equivalent is unclear, as they have not been treated as separate variables in molecular physiological studies. Additionally, molecular responses to these stresses have not been studied in leaf and root tissues simultaneously. We...

Although intact fruits of unripe cantaloupe (Cucumis melo L.) produce very little ethylene, a massive increase in ethylene production occurred in response to excision. The evidence indicates that this wound ethylene is produced from methionine via 1-aminocyclopropanecarboxylic acid (ACC) as in ripening fruits. Excision induced an increase in both ACC synthase and the enzyme converting ACC to et...

Genetic assessment was carried out on three Italian melon accessions by sequence and structural analysis of the internal transcribed spacer 1 (ITS1) from three populations belonging to two Cucumis melo L. varieties (madras and tendral). Alignment of the 18S-5.8S-26S sequences from three melon accessions showed that there were three single-nucleotide polymorphisms (SNPs) and one short insertion-...

Cucumis melo L. (C. melo) is a fruit with many medicinal properties and consumed in various countries. It utilised for chronic eczema to treat minor burns scrapes. The present study was conducted evaluate the antioxidant activity of methanolic extract Linn (MECM). A coarse powder prepared from seeds extracted methanol (absolute) by hot continuous percolation process accordance standard protocol...
