Threatened cockatoo adapts foraging strategy to survive habitat loss from fire

Ibis, EarlyView.
Fire regimes are changing across the globe as a result of human‐induced climate change. For granivorous bird species, changes in fire regimes can affect seed availability and the persistence of populations. We investigated the foraging behaviour of Glossy Black Cockatoos Calyptorhynchus lathami halmaturinus, a resource specialist, following large‐scale

MODIFIED ATMOSPHERE PACKAGING OF BEDDING PLANTS AND PLUG SEEDLINGS

HortScience, 1993
Poor post-production handling of bedding and seedling plants by mass-market outlets causes substantial quality reductions and product losses. Modified atmosphere packaging (MAP) may be a means to extend postharvest longevity and ease bedding plant handling.

Coniferyl aldehyde from the phenylpropanoid pathway targets pyruvate kinase in Dactylobotrys graminicola to confer sheath rot resistance in hulless barley

Journal of Integrative Plant Biology, EarlyView.
Hulless barley resists the newly identified sheath rot disease caused by the necrotrophic fungal pathogen Dactylobotrys graminicola by releasing coniferyl aldehyde, a natural compound that disrupts energy production in the fungus. ABSTRACT Dactylobotrys graminicola (Dgr), a necrotrophic fungal pathogen, has recently been identified as the causative ...

The ZmRACK1–ZmCDPK7–ZmAPX1 module regulates plant antiviral immunity

Journal of Integrative Plant Biology, EarlyView.
In maize, ZmRACK1 acts as a scaffold protein that bridges the cyclin‐dependent kinase ZmCDPK7 and the ascorbate peroxidase ZmAPX1, promoting ZmAPX1 activity to mitigate MCMV infection. Upon viral infection, P31 obstructs formation of the ZmRACK1‐ZmCDPK7‐ZmAPX1 complex, inhibiting ZmCDPK7‐mediated ZmAPX1 activity and promoting reactive oxygen species ...

Melatonin seed priming: A climate‐smart, green strategy to enhance abiotic stress tolerance in plants

Journal of Integrative Plant Biology, EarlyView.
This review synthesizes how melatonin seed priming preconditions seeds to enhance tolerance against diverse abiotic stresses. It highlights the underlying mechanisms and proposes an integrative roadmap of advanced molecular and breeding tools to design next‐generation, stress‐smart plants.

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

Journal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

Low-Damage Grasp Method for Plug Seedlings Based on Machine Vision and Deep Learning

Agronomy
In the process of plug seedling transplantation, the cracking and dropping of seedling substrate or the damage of seedling stems and leaves will affect the survival rate of seedlings after transplantation.

Ex vitro recovery of rough lemon (Citrus jambhiri) hybrids and identification with SSR markers

The Indian Journal of Agricultural Sciences, 2020
Rough lemon (Citrus jambhiri Lush) is one of the leading citrus rootstock around the world besides sour orange. In the present studies, rough lemon was crossed with X 639 and Swingle citrumelo at Department of Fruit Science, PAU Ludhiana during 2015-16.

Systemic acquired resistance: an emerging role for jasmonates in local signal biogenesis, translocation and distal signal decoding

New Phytologist, EarlyView.
Jasmonate signalling underpins establishment of plant systemic acquired resistance (SAR). Activation of the hypersensitive response (HR) not only contains the pathogen but establishes broad spectrum resistance in unchallenged leaves. The strong burst of reactive oxygen/nitrogen species initiating the HR results in lipid peroxidation (illustrated by ...
