Adventitious root (AR) formation in plants originates from non-root organs such as leaves and hypocotyls. Auxin signaling is essential for AR formation, but the roles of other phytohormones are less clear. In Arabidopsis, at least two distinct mechanisms can produce ARs, either hypocotyls part general architecture or wounded during de novo regeneration (DNRR). previous reports, gibberellin acid (GA) appeared to play reverse both types since GA treatment blocks etiolation-induced hypocotyls, whereas synthesis mutants apparently displayed reduced DNRR detached leaves. order clarify this contradiction, we employed biosynthesis inhibitor paclobutrazol (PBZ) found that PBZ had positive effects on Arabidopsis. Consistently, negative mechanisms, while loss promoted under our conditions. Our results show rescue declined difficult-to-root leaf explants erecta receptor mutants. Furthermore, transcriptional profiling revealed altered GA, brassinosteroids, auxin responses, which included up-regulation LBD16 well known its pivotal role initiation.

Food products are important sources of both endogenous and exogenous chiral molecules, whose distribution must be strictly controlled to ensure preserve food quality safety. Indeed, as an example, pesticides often administered racemic mixtures plants, while one enantiomer is active, the other may have unknown effects on human body could potentially pose a danger consumers. Therefore, information about naturally occurring artificially added compounds can help assess traceability. This work focuses most relevant findings research in field liquid chromatography safety quality, following success previous reviews published this topic. To avoid overlapping with reports, analysis covers last three years (2020-2023).

Bio-stimulants are crop supplements that have the potential to foster robust growth, increase productivity, and enhance quality of yields, even in face climate change abiotic stresses. Recent studies shed light on benefits plant bio-stimulants across horticultural perennial crops. However, their utilization is limited agricultural land, hydroponic systems, soilless media, fertigation systems. Uncertainties exist regarding safety, durability, inconsistent results glasshouse field applications. To expand global bio-stimulant market, it essential implement innovative strategies improve safety overall quality. In this context, we present a comprehensive review addresses key challenges developing bio-stimulants, along with practical insights constructive ideas for enhancing value By adopting these suggested improvements, production can be widely integrated into hydroponics improving growth disease prevention, given inherent bio-stimulation biocontrol properties. This article critically examines nanotechnology, encapsulation approaches, novel assessment methods efficacy, facilitate integration organic active components, application techniques, achieve precise delivery. Introducing products expected crucial promoting sustainable, high-value, intensive production.
