A polar gibberellin active in the dwarf rice (Oryza sativa L.) seedling and barley (Hordeum vulgare L.) half-seed assays was extracted from immature sour cherry (Prunus cerasus L.) seed and identified as gibberellin A(32) by gas-liquid chromatography and selected ion monitoring.

Tumorigenic strains of Agrobacterium spp. are responsible for crown gall disease of numerous plant species. We present here draft genome sequences of nonpathogenic Agrobacterium nepotum strain 39/7(T) (CFBP 7436(T), LMG 26435(T)), isolated from crown gall tumor on Prunus cerasifera, and tumorigenic Agrobacterium sp. strain KFB 330 (CFBP 8308, LMG 28674), isolated from galls on raspberry.

We present here the draft genome sequences of 14 Pseudomonas strains isolated from Prunus sp. plants in New Zealand and overseas. These new genomic data will be used to improve the detection of Pseudomonas strains found in imported plant material at the New Zealand border, improving the time involved in the process of biosecurity decision-making.

The genus Prunus, which contains 250–400 species, has ample genomic resources for the economically important taxa in group including cherries, peaches, and almonds. However, backbone of specifically position racemose relative to solitary corymbose groups, remains phylogenetically uncertain. Surprisingly, phylogenomic analyses resolve relationships are lacking. Here, we assemble transcriptomes f...

A new species belonging to the kinabaluensis group of the trachelid genus Utivarachna Kishida, 1940, U. lata sp. nov., is described from China. The male of U. fabaria Zhao & Peng, 2014 is described here for the first time based on specimens collected from Yunnan Province, China. The type material of U. gui (Zhu, Song & Kim, 1998) is re-examined and the species is redescribed.

It has been proposed that a pool of amino N, whose size is determined by aboveground N demand, cycles in the plant and regulates soil N uptake by exerting an inhibitory effect at the root level. Several experiments were carried out to study this hypothesis in almond trees [Prunus dulcis (Mill.) D.A. Webb]. Based on the evidence found, there is an association, at the whole tree level, between sa...

Sustainable water use is one of the greatest challenges of irrigated agricultural systems. This study presents the results related to the agronomic and physiological response to the deficit irrigation of almond trees (Prunus dulcis DA Webb Mill cv. Guara) under semiarid Mediterranean conditions in the Guadalquivir river basin (SW Spain). Two deficitirrigation strategies were tested: i) regulate...
