“…This could account for the low numbers of siliques and the numerous abortions observed in our study. The high yield losses of oilseed rape that we observed are in accordance with other studies (Bernhard et al, 1998;Manschadi et al, 2001;Mesa-García and García-Torres, 1986).…”

International audienceIn France, the fact that the holoparasitic plant Phelipanche ramosa has adapted to oilseed rape over the past two decades is deeply worrying, as it can cause over 80% yield losses. Its distribution area and the range of its host plants, whether they are cultivated plants or weeds, are expanding dramatically. As no natural regression of the infestation has been recorded so far, we undertook a detailed study of the different steps of the biological cycle of the P. ramosa/oilseed rape pathosystem to determine the adaptive traits that favour the parasite's success. We combined experimental approaches involving controlled conditions with in vitro and in pot co-cultivation on the one hand and a field trial on the other hand. These experiments allowed us to determine a 4-mm zone around host roots within which oilseed rape root exudates stimulate the germination of P. ramosa, the early action of host root exudates and the rapid fixation of the parasite on host roots. We also unveiled that P. ramosa was able to tune its biological cycle to that of oilseed rape. The important trophic relationships between the parasite and its host induced phenotypic (dwarfism, leaf chlorosis, silique abortion) as well as agronomical (90% yield losses) consequences on oilseed rape. Our results can constitute a relevant basis for further experimental studies. The research perspectives they open will focus on key-processes of the host-parasite relationship, and more particularly on the trophic relationships that are set up as far as carbon assimilates and minerals such as nitrogen are concerned.

“…Early plantings of pea are more severely infected 5. Delayed sowing is arguably the best‐documented traditional method for O. crenata avoidance 3, 78. However, delay of the sowing date implies shortening of the grain filling, which is detrimental to yield, particularly under Mediterranean conditions.…”

When people take drugs such as propranolol in response to trauma, it may dampen their bad memories – tempering recall of a traumatic event. We examined people's attitudes toward these drugs. Americans and New Zealanders read about a hypothetical assault inserting themselves into a scenario as a victim attacked while serving on a peace keeping mission (soldier role) or while walking home from a job as a restaurant manager (civilian role). Then they told us whether they should receive a memory dampening drug, and whether they would want to take a memory dampening drug. Subjects were negatively disposed towards a memory dampening drug, but Americans who adopted the soldier role were more in favor of having access to the drug than those who adopted the civilian role. We discuss the implications of these findings in relation to an increasing trend in ‘cosmetic neurology’, medicating with the goal of enhancement, rather than therapy.

“…Murdoch and Kebreab (2013) demonstrated that germination of Orobanche seeds cannot occur below a temperature of 4.9°C. Mesa-Garcia and Garcia-Torres found that O. crenata develops faster on broad bean roots under low winter temperatures (Mesa-García and García-Torres, 1986). However, unlike O. crenata, P. aegyptiaca parasitizes crops the year over at all temperatures.…”

Thermal Time Model for Egyptian Broomrape (Phelipanche aegyptiaca) Parasitism Dynamics in Carrot (Daucus carota L.): Field Validation

Carrot, a highly profitable crop in Israel, is severely damaged by Phelipanche aegyptiaca parasitism. Herbicides can effectively control the parasite and prevent damage, but for optimal results, knowledge about the soil–subsurface phenological stage of the parasite is essential. Parasitism dynamics models have been successfully developed for the parasites P. aegyptiaca, Orobanche cumana, and Orobanche minor in the summer crops, tomato, sunflower, and red clover, respectively. However, these models, which are based on a linear relationship between thermal time and the parasitism dynamics, may not necessarily be directly applicable to the P. aegyptiaca–carrot system. The objective of the current study was to develop a thermal time model to predict the effect of P. aegyptiaca parasitism dynamics on carrot growth. For development and validation of the models, data was collected from a temperature-controlled growth experiment and from 13 plots naturally infested with P. aegyptiaca in commercial carrot fields. Our results revealed that P. aegyptiaca development is related to soil temperature. Moreover, unlike P. aegyptiaca parasitism in sunflower and tomato, which could be predicted both a linear model, P. aegyptiaca parasitism dynamics on carrot roots required a nonlinear model, due to the wider range of growth temperatures of both the carrot and the parasite. Hence, two different nonlinear models were developed for optimizing the prediction of P. aegyptiaca parasitism dynamics. Both models, a beta function model and combined model composed of a beta function and a sigmoid curve, were able to predict first P. aegyptiaca attachment. However, overall P. aegyptiaca dynamics was described more accurately by the combined model (RMSE = 14.58 and 10.79, respectively). The results of this study will complement previous studies on P. aegyptiaca management by herbicides to facilitate optimal carrot growth and handling in fields infested with P. aegyptiaca.
