Fruit ripening is a coordinated series of biochemical changes that renders the fruit attractive to eat. The fruit may soften, develop colour, change starch or acid into sugar, become flavoursome, produce more ethylene, increase in sensitivity to ethylene, and respire more rapidly. This syndrome is under contemporary genetic control as illustrated by mutants with fruit that develop normally but ...

In grapevine, fruit abscission is known to occur within the first two to three weeks after flowering, but the reason why some berries in a cluster persist and others abscise is not yet understood. Ethylene sensitivity modulates abscission in several fruit species, based on a mechanism where continuous polar auxin transport across the pedicel results in a decrease in ethylene perception, which p...

To understand how auxin regulates sensitivity of abscission zone (AZ) tissues to ethylene, we used a polymerase chain reaction-based subtractive approach to identify gene transcripts in Mirabilis jalapa AZs that changed in abundance during the time the zones became competent to abscise in response to exogenous ethylene. Transcript expression was then examined in leaf and stem AZs over the perio...

Tropospheric ozone, a phytotoxic air pollutant, has inadvertently increased since industrial era and its effect on agricultural crops gained urgent scientific attention. The present study aims to evaluate the response of blackgram varieties (Vigna mungo L.) exposed elevated ozone stress (100 ppb) with antiozonant (Ethylene diurea at 300 ppm). was conducted during two seasons effectiveness ethyl...

Using a small-core single-mode fiber (SCSMF), a novel relative humidity (RH) sensor based on an SMF28-SCSMF-SMF28 fiber structure was proposed in this paper. By depositing a humidity sensitive material, such as poly (ethylene oxide) (PEO) on the bare SCSMF fiber, the proposed structure can act as an RH sensor with high sensitivity. Experiments demonstrated that the proposed RH sensor with PEO c...

Wheat (Triticum aestivum L.) is one of the most important staple crops. Most wheat varieties are sensitive to salt stress, which a major limitation for production. To develop salt-tolerant sustainable grain production, we used ethylmethylsulfonate mutagenize over 90,000 seeds cultivar Luyuan502. A total 2000 lines were identified after screening plants in salinized field. We further analyzed et...
