Field testing of strategies for fire blight control in organic fruit growing [PDF]

open access: yes, 2008
In organic fruit growing effective control strategies are needed to prevent blossom infections by the fire blight pathogen Erwinia amylovora. Many potential control agents are under discussion and have been tested in vitro and in vivo.

Changing Rainfall Drives Locally Asynchronous Reproduction of Tropical Birds via Modular Trophic Pathways

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
In low‐latitude mountains, we found insectivorous bird communities switched from breeding before to after the dry season at a threshold in dry‐season insects. Localized breeding season reversal of insectivores across wet‐to‐dry gradients magnified short‐term effects of drought and contrasted with the seasonal stability of nectar‐fruit consumers.

Effects of control sprays on russetting of Bartlett pears

open access: yesCalifornia Agriculture, 1973
Russet (small, corky, brown spots on 1 the surface of fruit) makes pears less attractive to buyers and so reduces prices paid for fresh fruit even though it does not affect the eating or keeping quality.

Integrative phylogenomics and morphology reveal the evolution and biogeography of Encephalartos (Zamiaceae)

open access: yesJournal of Systematics and Evolution, Volume 64, Issue 2, Page 295-312, March 2026.
We aimed to conduct phylogenetic analyses of Encephalartos, a cycad genus endemic to Africa, using 3545 single‐copy nuclear genes extracted from transcriptome data, covering 64/65 of the recognized species, along with inference of divergence times using two secondary calibration points.

Genomewide prediction to target russet formation in apple

open access: yesFruit Research
Russet formation in apple (Malus domestica Borkh.) is a superficial skin disorder that detracts from fruit appearance and is likely controlled by many small-effect quantitative trait loci (QTLs). Genomewide prediction has been reported to be an effective
