Infection Processes Differ Among Botrytis cinerea, Cladosporium cladosporioides and Neopestalotiopsis macadamiae in Macadamia Flowers

open access: yesPlant Pathology, EarlyView.
Light and scanning electron microscopy revealed the distinct infection mechanisms of Botrytis cinerea, Cladosporium cladosporioides and Neopestalotiospis macadamiae at different flower stages in macadamia. ABSTRACT Botrytis cinerea, Cladosporium cladosporioides and Neopestalotiopsis macadamiae are the foremost causative agents of the flower blight ...

Dactyliform appendage contributes to delayed selfing in the diminutive orchid Stigmatodactylus sikokianus

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 894-900, July 2025.
Understanding plant reproductive strategies is vital for conserving endangered species. This study reveals a novel self‐pollination mechanism in the diminutive orchid Stigmatodactylus sikokianus, facilitated by the movement of a finger‐like appendage beneath the stigma.

Decrease of sexual organ reciprocity between heterostylous primrose species, with possible functional and evolutionary implications [PDF]

open access: yes, 2017
Background and Aims Heterostyly is a floral polymorphism that has fascinated evolutionary biologists since Darwin's seminal studies on primroses. The main morphological characteristic of heterostyly is the reciprocal placement of anthers and stigmas in ...

A point mutation in IAA34 confers resistance to the auxin herbicide 2,4‐D in Sisymbrium orientale

open access: yesPest Management Science, Volume 81, Issue 7, Page 3523-3531, July 2025.
A point mutation in domain IV of SoAux/IAA34‐R provides resistance to 2,4‐D. Abstract BACKGROUND Sisymbrium orientale has evolved resistance to 2,4‐D in Australia due to a 27 bp deletion in SoIAA2. However, one population of Sisymbrium orientale resistant to 2,4‐D (R1) did not contain the SoIAA2Δ27, suggesting another 2,4‐D resistance mechanism was ...

Biological Flora of Britain and Ireland: Cytisus scoparius*

open access: yesJournal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Understanding Flower Frost Tolerance in Almond (Prunus dulcis): The Role of Phenology, Cultivar and Sugars Content

open access: yesJournal of Agronomy and Crop Science, Volume 211, Issue 4, July 2025.
ABSTRACT Freezing temperatures during the flower and fruitlet stages are considered one of the most limiting factors for almond cultivation. Understanding the minimum temperature that reproductive organs can resist without damage is crucial for adapting the crop to different environmental conditions and for breeding cultivars with enhanced tolerance to

OsPRK1/2/3‐mediated reactive oxygen species signaling is required for pollen tube germination in rice

open access: yesJournal of Integrative Plant Biology, Volume 67, Issue 7, Page 1965-1981, July 2025.
The rice pollen‐specific receptor‐like kinases OsPRK1, OsPRK2, and OsPRK3 play a crucial role in reactive oxygen species (ROS)‐mediated pollen hydration and germination. Triple mutants display male sterility due to decreased ROS levels and impaired pollen hydration, and their germination phenotype can be partially restored by exogenous application of ...
