Influência de fitorreguladores e nitrato de potássio na germinação de sementes e no crescimento de porta-enxerto de Citrus amblycarpa Influence of growth regulators and potassium nitrate on Citrus amblycarpa seed germination and growth of rootstocks

open access: yesScientia Agricola, 1994
Foram avaliados os efeitos de fitorreguladores (giberelinas e citocininas) e nitrato de potássio (KNO3), na germinação de sementes e na promoção do crescimento de "seedlings" do porta-enxerto 'Nasnaran' (Citrus amblycarpa Ochese).

PtoHY5 integrates photoperiodic signals with the ABA pathway to coordinate growth cessation and dormancy in Populus

open access: yesJournal of Integrative Plant Biology, EarlyView.
In Populus, short days deactivate the growth‐promoting protein PtoHY5, turning off a growth accelerator and activating an abscisic acid‐driven brake. This directly couples growth cessation with dormancy, underscoring the role of abscisic acid in synchronizing these transitions for winter survival.

Drought and salinity stress remodel Asian rice (Oryza sativa) leaf development through cell‐type‐specific regulatory programs

open access: yesNew Phytologist, EarlyView.
Osmotic stressors induce developmental and physiological changes in rice (Oryza sativa) seedlings, which are modulated by cell‐type‐specific gene expression and regulatory networks. We exposed plants to two levels of drought and salinity stress and measured the effects of these stressors on developing leaves by measuring physiological traits, ion ...

Biogenic Synthesis and Spatial Distribution of Endogenous Phytohormones and Ginsenosides Provide Insights on Their Intrinsic Relevance in Panax ginseng

open access: yesFrontiers in Plant Science, 2019
Ginseng, the root and rhizome of Panax ginseng C. A. Mey., is a well-known and valuable traditional Chinese medicine. The pharmacological activities of ginseng are mainly attributed to the presence of ginsenosides, which are considered to be critical ...

Revisiting the Molecular Roadmap for Sugar Crops: Genome Reading, Trait Writing and Variety Redesigning

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...

Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

MYB Factors: Hubs of Plant Stress and Hormone Crosstalk

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT MYB transcription factors function as main regulatory hubs that integrate environmental signals with multi‐hormonal pathways to synchronize plant growth, metabolism and stress responses. This review delineates the regulatory roles of MYB in the signalling pathway of salicylic acid, jasmonic acid, ethylene and abscisic acid signalling.

ERF Transcription Factor NaERFIDOG Regulates JA‐Induced Defence and Growth Inhibition in Nicotiana attenuata Upon Alternaria alternata Infection

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Jasmonate (JA) regulates defence responses in plants. However, JA‐induced defence often results in growth inhibition. This process is largely mediated by MYC2, the master regulator of JA signalling. Nevertheless, the underlying molecular mechanisms have not yet been fully uncovered.

Evolution‐Inspired Engineering of Diterpene Biosynthesis via Chloroplast Genome Modification

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Terpenes constitute the largest and most structurally diverse class of plant secondary metabolites, with critical roles in plant‐environment interactions and broad industrial applications. Although nuclear genome engineering of terpene pathways has been extensively explored, chloroplast genome engineering remains largely undeveloped, with all ...

The involvement of gibberellins in phytochrome-controlled flowering of Pharbitis nil

open access: yesActa Societatis Botanicorum Poloniae, 2014
The seedlings of Pharbitis nil, a sesitive short-day plant (SDP), were cultivated under special photoperiodic conditions: 72-h-long darkness, 24-h-long white light with low intensity, 24-h-long inductive night.
