Nonhost resistance is the outcome of most plant/pathogen interactions, but it has rarely been described in Rosaceous fruit species. Apple (Malus x domestica Borkh.) have a nonhost resistance to Venturia pyrina, the scab species attacking European pear (Pyrus communis L.). Reciprocally, P. communis...

Arabinogalactan proteins (AGPs) are widely distributed in the plant kingdom and play a vital role during the process of plant sexual reproduction. In this study, we performed a comprehensive identification of the PbrAGPs expressed in pear pollen and further explored their influences on pollen tube...

Brown and black spots, caused by Stemphylium and Alternaria species, are important fungal diseases affecting European pear (Pyrus communis) in orchards. Both fungal genera cause similar symptoms, which could favor misidentification, but Alternaria spp. are increasingly reported due to the changing...

Erwinia amylovora causes a devastating fire blight disease in apples and pears. One of the main virulence determinants in E. amylovora is the hypersensitive response (HR) and pathogenicity (hrp)-type III secretion system (T3SS), which is activated by the RpoN-HrpL sigma factor cascade. However, the ...

This study was carried out on a cactus pear orchard grown in calcareous soil at El-Hammam region, Matrouh Governorate, over two consecutive seasons in 2020 and 2021. This work aimed to find the best mineral fertilization treatment for increasing the yield of plants, as it has yet to be studied...

Mode of reproduction in the genus Opuntia varies among species but often includes both vegetative and sexual reproduction, with the latter often facilitated by animal seed dispersal. In this multi-year study, we examined fruit and seed production and seed dispersal in the Mojave prickly pear (...

Opuntia is a genus of plants known as prickly pear cactus (nopales), with about 200 species, and is taxonomically complicated. The present study was focused on characterizing micromorphology and providing a phylogenetic hypothesis to place Opuntia setocarpa (described in 2017) in relation to other...

In the semi-arid forest of Wari (Ayacucho-Peru), the prickly pear (Opuntia ficus-indica) predominates among the plant species, and in this environment, the bedbud Paraedessa heymonsi and the spider Argiope sp. share the ecosystem. P. heymonsi infests prickly pear and Argiope sp. participates as a...

Fruit cracking is a physiological disorder and results in significant economic losses. Calcium (Ca) plays important roles in the pear fruit cracking process, however, the underlying molecular mechanism of fruit cracking induced by Ca is poorly understood. In the present study, using cracking...

In Iran, Arasbaran area is a very rich zone which has most of Iran\'s herbaceous species including medicinal, ornamental and edible products. Most of the trees in this area are oak, kikem, crimson, barberry, wild pomegranate, wild apples, wild pears and raspberries, and cucumbers, along with fruits ...
