“…ABC transporters mainly use the energy generated via adenosine triphosphate hydrolysis to perform reverse concentration gradient transmembrane transport. Their transport substrates include amino acids, nucleotides, sugars, and metal ions 38,39 . A few studies have investigated the role of ABC transporters in the accumulation of flavor‐related metabolites and the formation of unique flavor during tea withering.…”

BackgroundWithering is the first processing procedure of beauty tea, and there are few reports on the impact of withering methods on the quality of beauty tea and its regulatory mechanisms.ResultsThrough comparison of fresh tea leaves (FT) with the leaves at Indoor natural Withering 18h (IWT‐18) and Outdoor Solar Withering 6h (OWT‐6), which were collected at the end of the two withering processes, 17282 and 13984 differentially expressed genes (DEGs) were screened and 267 and 154 differential metabolites (DMs) were identified, respectively. Coexpression network revealed that a large number of DEGs and DMs were enriched in phenylpropanoid, flavonoid, and adenosine Triphosphate binding (ABC) transporter pathways, and the number of DMs and DEGs in IWT‐18 vs FT exceeded that in OWT‐6 vs FT. Both withering methods promoted a significant increase in content of phenylalanine and upregulation of β‐glucoside (BGLU) expression in the phenylpropanoid metabolism pathway. The five proanthocyanidins related to theaflavins in the flavonoid synthesis pathway was more significant accumulation in FT vs IWT‐18 than in FT vs OWT‐6. Meanwhile, both withering methods can affect the ABC transporter pathway to promote the accumulation of amino acids and their derivatives, but different withering methods affect different ABC transporter families. Outdoor withering with more severe abiotic stress has a greater impact on the ABCG family, while indoor withering has a more significant effect on the ABCC family. Sensory evaluation results showed that the dry tea of IWT‐18 was slightly better than that of OWT‐6 because of longer withering time and more thorough substance transformation.ConclusionIn conclusion, the formation of honey flavor in beauty tea may be closely related to the DEGs and DMs in these three pathways. Our research provides theoretical data support for further revealing the mechanism of quality formation during the withering process of beauty tea.This article is protected by copyright.

“…Plants often employ two defense mechanisms to deal with the toxicity of HMs, and these mechanisms have been comprehensively reviewed in recent literature (Zhao et al, 2022; Yan et al, 2022; Ghuge et al, 2023). One of them is to limit the uptake of metals into plant cells, also termed the exclusion mechanism (Dalvi and Bhalerao, 2013).…”

Due to anthropogenic activities, environmental pollution of heavy metals/metalloids (HMs) has increased and received growing attention in recent decades. Plants growing in HM‐contaminated soils have slower growth and development, resulting in lower agricultural yield. Exposure to HMs leads to the generation of free radicals (oxidative stress), which alters plant morpho‐physiological and biochemical pathways at the cellular and tissue levels. Plants have evolved complex defense mechanisms to avoid or tolerate the toxic effects of HMs, including HMs absorption and accumulation in cell organelles, immobilization by forming complexes with organic chelates, extraction via numerous transporters, ion channels, signaling cascades, and transcription elements, among others. Nonetheless, these internal defensive mechanisms are insufficient to overcome HMs toxicity. Therefore, unveiling HMs adaptation and tolerance mechanisms is necessary for sustainable agriculture. Recent breakthroughs in cutting‐edge approaches such as phytohormone and gasotransmitters application, nanotechnology, omics, and genetic engineering tools have identified molecular regulators linked to HMs tolerance, which may be applied to generate HMs‐tolerant future plants. This review summarizes numerous systems that plants have adapted to resist HMs toxicity, such as physiological, biochemical, and molecular responses. Diverse adaptation strategies have also been comprehensively presented to advance plant resilience to HMs toxicity that could enable sustainable agricultural production.
