Cell‐type‐specific gating of gene regulatory modules as a hallmark of early immune responses in Arabidopsis leaves

New Phytologist, EarlyView.
Summary In plants, multiple cell types contribute to immunity, but what division of labor exists among cell types when immunity is activated? We compared, at single‐cell resolution, the response of Arabidopsis thaliana leaf cells during pattern‐triggered and effector‐triggered immunity (PTI/ETI), sampled at 3 and 5 h after infection with Pseudomonas ...

The environmentally responsive plant epigenome: insights from jasmonate signaling

New Phytologist, EarlyView.
Summary The environmental responsiveness of the plant epigenome is essential for spatiotemporally precise gene regulation, enabling plants to adapt to external cues. Elucidating the mechanisms underlying this responsiveness is therefore fundamental to deciphering the molecular logic of plant‐environment interactions.

Variation in herbivore defense strategies among plant species differing in elevational distribution and the role of temperature in defense

New Phytologist, EarlyView.
Summary Temperature influences the distribution and performance of both plants and insect herbivores. Consequently, plant–herbivore interactions are likely to vary across thermal gradients, which could affect the evolution of plant defense. Furthermore, temperature fluctuations may elicit immediate changes in defense.

Discrete and cell‐specific hypoxic responses in Arabidopsis roots resolved by single‐nuclei transcriptomics

New Phytologist, EarlyView.
Summary With the intensification of unpredictable flooding events because of global warming, there is a need to understand how root cells perceive and respond to oxygen deprivation. The use of high‐throughput single‐nuclei RNA‐sequencing (snRNA‐Seq) allows the examination of gene expression profiles in discrete cell types.

Fruit respiration: putting alternative pathways into perspective

New Phytologist, EarlyView.
Summary Over the past century, research has significantly advanced our understanding of fruit respiration, from (eco)physiological processes to molecular mechanisms. This review focuses on the functional relevance and regulatory roles of mitochondrial alternative respiratory pathways (ARPs) during fruit growth and ripening.

Methyl jasmonate and cis jasmone induce apoptosis in Pc-3 and LncaP prostate cancer lines

, 2005
Methyl jasmonate (MJ) and cis jasmone (CJ), lipid-derived plant stress hormones, were studied for their effects against both hormone dependent (LNCaP) and hormone independent (PC3) human prostate cancer cell lines. Both 2 mM MJ or CJ inhibited the growth

Quiescence of postharvest pathogens: a fungal inhibition process or an immune response of the unripe host fruit?

New Phytologist, EarlyView.
Summary Postharvest pathogens can infect fresh produce both before and after harvest, by direct or wound‐enhanced penetration, remaining quiescent until ripening. Biotrophic‐like postharvest pathogens persist beneath host cells and can remain in a state of quiescence.

Decoding plant defense signaling using the defenseless mutant

New Phytologist, EarlyView.
Summary Can plants live without defenses? Mutant analysis in Arabidopsis thaliana has identified numerous regulators of biotic, abiotic, and hormone‐based defenses, but the redundancy among separate defense pathways remains unexplored. We constructed an Arabidopsis mutant, defenseless, lacking six canonical defense pathways using abi1‐1 (abscisic acid),
