In troduct ion The fruit skin (cuticle and epidermis) provides barrier protection against infection by pathogens. Most fungi are unable to penetrate healthy fruit skin and must enter through wounds. Fruit resistance to infection resulting from the biochemical action of tissues is not the result of a single compound or a single mechanism. Multiple systems with complex interactions may be involve...

Precision agriculture is a concept that encompasses various technologies aimed at optimizing the management of agricultural activities. The main aim this investigation to evaluate environmental and economic performance precision practices on production stone fruit crop (nectarine) using life cycle approach consider cradle-to-farm gate scope. results have been compared against traditional unifor...

Pea (Pisum sativum L.) lines G2 (dwarf) and NGB1769 (tall) (Sn Hr) produce flowers and fruit under long (LD) or short (SD) days, but senesce only under LD. Endogenous gibberellin (GA) levels were inversely correlated with photoperiod (over 9-18 h) and senescence: GA20 was 3-fold and GA1 was 10- to 11-fold higher in flowering SD G2 shoots, and the vegetative tissues within the SD apical bud cont...

North American pawpaw [Asimina triloba (L.) Dunal] is a temperate climate member of the Annonaceae used as an ornamental and specialty tree fruit crop. Micropropagation could provide a clonal propagation method for plant production and contribute to germplasm preservation. A pawpaw culture was established that has produced shoot-bud clusters for over six years when maintained on a plant growth ...

The transcriptomes of five pear cultivars, 'Hosui' (P. pyrifolia), 'Yali' (P. bretschneideri), 'Kuerlexiangli' (P. sinkiangensis), 'Nanguoli' (P. ussuriensis), and 'Starkrimson' (P. communis) were sequenced at seven key fruit developmental stages, from fruit setting to maturation and fruit senescence after harvesting. In total, 33,136 genes that could be mapped by reads, were analyzed. Most gen...

Fire blight is a devastating disease of rosaceous plants caused by the Gram-negative bacterium Erwinia amylovora. This pathogen delivers virulence proteins into host cells utilizing the type III secretion system (T3SS). Expression of the T3SS and of translocated and secreted substrates is activated by the alternative sigma factor HrpL, which recognizes hrp box promoters upstream of regulated ge...
