| fluttering of growing leaves as a way to reach flatness: experimental evidence on persea americana. | simple leaves show unexpected growth motions: the midrib of the leaves swings periodically in association with buckling events of the leaf blade, giving the impression that the leaves are fluttering. the quantitative kinematic analysis of this motion provides information about the respective growth between the main vein and the lamina. our three-dimensional reconstruction of an avocado tree leaf shows that the conductor of the motion is the midrib, presenting continuous oscillations and inducing ... | 2018 | 29343634 |

| epidemiology, pathology and identification of colletotrichum including a novel species associated with avocado (persea americana) anthracnose in israel. | anthracnose disease caused by colletotrichum species is a major constraint for the shelf-life and marketability of avocado fruits. to date, only c. gloeosporioides sensu lato and c. aenigma have been reported as pathogens affecting avocado in israel. this study was conducted to identify and characterize colletotrichum species associated with avocado anthracnose and to determine their survival on different host-structures in israel. the pathogen survived and over-wintered mainly on fresh and dry ... | 2017 | 29158592 |
| generation of composite persea americana (mill.) (avocado) plants: a proof-of-concept-study. | avocado (persea americana (mill.)), an important commercial fruit, is severely affected by phytophthora root rot in areas where the pathogen is prevalent. however, advances in molecular research are hindered by the lack of a high-throughput transient transformation system in this non-model plant. in this study, a proof-of-concept is demonstrated by the successful application of agrobacterium rhizogenes-mediated plant transformation to produce composite avocado plants. two ex vitro strategies wer ... | 2017 | 29053757 |
| management of fruit species in urban home gardens of argentina atlantic forest as an influence for landscape domestication. | home gardens are considered germplasm repositories and places for experimentation, thus they are key sites for the domestication of plants. domestication is considered a constant process that occurs along a continuum from wild to managed to domesticated populations. management may lead to the modification of populations and in other cases to their distribution, changing population structure in a landscape. our objective is focused on the management received in home gardens by perennial species o ... | 2017 | 29033964 |

| transcriptomic analysis of avocado hass (persea americana mill) in the interaction system fruit-chitosan-colletotrichum. | avocado (persea americana) is one of the most important crops in mexico as it is the main producer, consumer, and exporter of avocado fruit in the world. however, successful avocado commercialization is often reduced by large postharvest losses due to colletotrichum sp., the causal agent of anthracnose. chitosan is known to have a direct antifungal effect and acts also as an elicitor capable of stimulating a defense response in plants. however, there is little information regarding the genes tha ... | 0 | 28642771 |
| α-copaene is an attractant, synergistic with quercivorol, for improved detection of euwallacea nr. fornicatus (coleoptera: curculionidae: scolytinae). | the tea shot-hole borer, euwallacea fornicatus eichhoff, is an ambrosia beetle endemic to asia and a pest of commercial tea, camellia sinensis (l.) kuntze. recently, a complex of species morphologically similar to e. fornicatus has been recognized, which includes new pests established in israel and the usa, both in california and florida. collectively termed e. nr. fornicatus, these cryptic species carry symbiotic fusarium spp. fungi, some of which cause dieback disease in susceptible hosts, whi ... | 2017 | 28609448 |
| testing plant use of mobile vs immobile soil water sources using stable isotope experiments. | we tested for isotope exchange between bound (immobile) and mobile soil water, and whether there is isotope fractionation during plant water uptake. these are critical assumptions to the formulation of the 'two water worlds' hypothesis based on isotope profiles of soil water. in two different soil types, soil-bound water in two sets of 19-l pots, each with a 2-yr-old avocado plant (persea americana), were identically labeled with tap water. after which, one set received isotopically enriched wat ... | 2017 | 28556977 |
| control of anthracnose disease via increased activity of defence related enzymes in 'hass' avocado fruit treated with methyl jasmonate and methyl salicylate. | development of anthracnose disease caused by colletotrichum gloeosporioides penz. is one of the major issues within the avocado supply chain. exposure to methyl jasmonate (meja) and methyl salicylate (mesa) vapours at 10 and 100µmoll(-1) was investigated as an alternative solution to commercial fungicide - prochloraz® that is currently being used by the industry. the incidence of anthracnose disease was found to be significantly reduced in 'hass' avocado fruit treated with meja or mesa vapours, ... | 2017 | 28551220 |
| attraction of the euwallacea sp. near fornicatus (coleoptera: curculionidae) to quercivorol and to infestations in avocado. | the euwallacea sp. near fornicatus (euwallacea sp. 1 hereafter) feeds on many woody shrubs and trees and is a pest of avocado, persea americana mill., in several countries including israel and the united states. quercivorol baits are commercially available for euwallacea sp. 1 females (males do not fly), but their attractive strength compared to other pheromones and potential for mass trapping are unknown. we used sticky traps baited with quercivorol released at 0.126 mg/d (1×) and at 0.01×, 0.1 ... | 2017 | 28541523 |
| maintaining postharvest quality of cold stored 'hass' avocados by altering the fatty acids content and composition with the use of natural volatile compounds - methyl jasmonate and methyl salicylate. | low temperatures are often used to reduce metabolic processes and extend the storage life of fruit; however, in the case of avocado, a temperature below 3 °c will often result in the development of physiological disorders associated with chilling injury. the objective of this study was to investigate the ability of methyl jasmonate (meja) and methyl salicylate (mesa) vapours to alleviate chilling injury in 'hass' avocado fruit kept at 2 °c for 21 days followed by 6-7 days of shelf-life at 20 °c, ... | 2017 | 28447342 |
| cold disinfestation of "hass" avocado (persia americana) of three species of fruit fly (diptera: tephritidae)-ceratitis capitata, ceratitis rosa, and ceratitis cosyra. | the avocado industry is important in south africa, but access to certain markets is impeded by the presence of phytosanitary pests. one of the ways of securing entry to these markets is to demonstrate that a mitigating treatment will result in there being a negligible chance of accidental importation. in cold treatment comparative studies at 0 °c and 2 °c of immature stages of ceratitis capitata (wiedemann), ceratitis rosa karsch, and ceratitis cosyra (walker) in "hass" avocado, the third instar ... | 2017 | 28444314 |
