Shrubs inhibit plant diseases by intercepting light in alpine meadows

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change is disproportionately impacting mountain ecosystems, leading to widespread shrub expansion into alpine meadows. Shrub encroachment alters the albedo, carbon budget and warming rate in alpine grasslands, but it remains challenging to predict how shrub ...

Regulation of Expression of Proteinase Inhibitor Genes by Methyl Jasmonate and Jasmonic Acid [PDF]

Plant Physiology, 1992
Gel electrophoretic analysis of the proteinase inhibitor proteins induced in tomato leaves by airborne methyl jasmonate (EE Farmer, CA Ryan [1990] Proc Natl Acad Sci USA 87: 7713-7716) revealed the new appearance of inhibitors I and II and two other, higher molecular mass proteins (63.5 and 87 kilodaltons). Northern analysis of methyl jasmonate-induced

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Rice JASMONATE RESISTANT 1 is involved in phytochrome and jasmonate signalling [PDF]

Plant, Cell & Environment, 2008
ABSTRACTJasmonic acid (JA) is an important negative regulator of light‐regulated coleoptile elongation in rice. We isolated rice JASMONATE RESISTANT 1 (osjar1) mutants from the Tos17 mutant panel by BLAST search. In far‐red and blue lights, osjar1 coleoptiles were longer if compared with the wild type (WT), indicating that OsJar1 participates in the ...

Inducible tomato defences persist in detached leaves, despite differential plant variety and gene‐dependent expression

Ecological Entomology, EarlyView.
Short‐ and long‐term expression of PPO‐D, PI‐IIc and PR‐1a were assessed in intact plants and detached tomato leaves of two varieties infested with Tetranhycus urticae. Tomato defences were induced in both intact and detached leaves, but the induction levels varied with plant variety and gene assessed.

The competitive interplay of 12‐oxophytodienoic acid (OPDA), protein thiols, and glutathione

The FEBS Journal, EarlyView.
12‐Oxophytodienoic acid (OPDA) is a phytohormone involved in plant growth and stress defense. Due to its cyclopentenone moiety, OPDA can form Michael adducts with thiol‐containing compounds such as glutathione and cysteine residues of proteins, resulting in alterations of the cellular redox regulatory network.

Salt glands in exo‐recretohalophytes: Development, physiological functions, and prospects for improving crop salt tolerance

Journal of Integrative Plant Biology, EarlyView.
This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

Enhancing essential oil production in rosemary (Rosmarinus officinalis L.) with salicylic acid and methyl jasmonate and its relationship to spectral indices

Folia Horticulturae
Rosemary is a widely used herb known for its diverse health benefits, attributed to its essential oil content. However, cultivating rosemary requires careful attention to environmental conditions, particularly in regions with unpredictable climates such ...

2R,3R-Butanediol, a Bacterial Volatile Produced by Pseudomonas chlororaphis O6, Is Involved in Induction of Systemic Tolerance to Drought in Arabidopsis thaliana

Molecular Plant-Microbe Interactions, 2008
Root colonization of plants with certain rhizobacteria, such as Pseudomonas chlororaphis O6, induces tolerance to biotic and abiotic stresses. Tolerance to drought was correlated with reduced water loss in P.

The GmGT‐2F, a trihelix transcription factor, regulates seed oil content by directly activating GmAGAL transcription in soybean

Journal of Integrative Plant Biology, EarlyView.
In soybean, the trihelix transcription factor GmGT‐2F positively regulates the expression of the α‐galactosidase gene GmAGAL, thereby modulating seed oil content. The cyclophilin GmCYP2 interacts with GmGT‐2F and suppresses GmAGAL activation. Haplotype diversity analysis of GmGT‐2F, GmCYP2, and GmAGAL identified favorable haplotype combinations ...
