Control of Carbon Assimilation and Partitioning by Jasmonate: An Accounting of Growth–Defense Tradeoffs

Plants, 2016
Plant growth is often constrained by the limited availability of resources in the microenvironment. Despite the continuous threat of attack from insect herbivores and pathogens, investment in defense represents a lost opportunity to expand photosynthetic

ARF6 integrates auxin and gibberellin signaling to promote stone cell lignification in pear via the HB49‐MYB169 module

New Phytologist, EarlyView.
Summary Stone cells originate from secondary cell wall thickening and contain abundant lignin. Their excessive accumulation compromises pear fruit quality, yet the endogenous hormonal mechanisms governing stone cell formation remain unclear. Here, co‐expression network analysis using transcriptome data – the flesh of 206 sand pear accessions sampled at

Inhibition of jasmonic acid‐isoleucine conjugating enzyme JAR1 shifts the local and systemic leaf signals and metabolic profiles in Arabidopsis

New Phytologist, EarlyView.
Summary Jasmonates (JAs)‐mediated pathways are central signaling hubs in plant defense responses. However, the identification of mobile and nonmobile signals involved in downstream systemic signaling is still less studied. Here, we investigate the role of the jasmonic acid‐isoleucine (JA‐Ile) conjugating enzyme, JAR1, in shifting wound‐induced local ...

Transcriptomic and hormonal dynamics in relation to adventitious rooting of two parental Petunia species highlight a coordinated activation of the jasmonate and auxin pathways and an important role of upper-shoot-derived auxin influx

Frontiers in Plant Science
IntroductionAdventitious rooting of cuttings is a key developmental process for the vegetative propagation of many crops that involves phytohormone-controlled reprogramming and redifferentiation of specific cells in the stem base.

Endophyte‐induced systemic spatial reprogramming of metabolism in Populus trichocarpa roots under drought

New Phytologist, EarlyView.
Summary Beneficial, facultative endophytes help plants thrive in challenging environments by altering their host's metabolism, but how these cellular scale metabolic changes propagate to the systems biology scale is unknown. In this work, we employed a high‐resolution chemical imaging approach to map metabolic changes at the Populus trichocarpa root ...

Genome-Wide Identification and Characterization of JAZ Protein Family in Two Petunia Progenitors

Plants, 2019
Jasmonate ZIM-domain (JAZ) family proteins are the key repressors in the jasmonate signaling pathway and play crucial roles in plant development, defenses, and responses to stresses.

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, EarlyView.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Integrated Transcriptomic and Metabolomic Analysis of Color Changes in Maize Root Systems Treated with Methyl Jasmonate

Biology
(1) Background: As a high-biomass cereal crop, maize provides substantial raw materials for food, animal feed, and processing industries. Plant root systems, vital for nutritional support, are directly vulnerable to diverse stressors that result in ...

The Advantaged Salt Inducible Suaeda salsa SsNRT2.5 and Its Promoter Significantly Enhance Nitrate Transport Efficiency and Salt Tolerance in Transgenic Arabidopsis and Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Efficient nitrogen (N) uptake is critical for crop yield, but soil salinization inhibits plant nitrogen acquisition. In this study, the nitrate (NO3−) transporter gene SsNRT2.5 and its promoter from the halophyte Suaeda salsa was investigated to elucidate the functional role in NO3− transport under salinity and low NO3−–N conditions.
