Solution Transfer

Our understanding of nutrient transfer between host and flowering parasitic plants is usually based mainly on physiological concepts, with little information on haustorial structure related to function. The aim of this paper is to study the haustorial interface and possible pathways of water and solute transfer between a number of host and parasites.Haustorial tissues were fixed in glutaraldehyde and embedded in glycol methacrylate (LM), or fixed in glutaraldehyde then OsO4 and embedded in Spurr’s resin (TEM).Our study shows that lumen to lumen continuity occurs between tracheary elements of a host and four S.W. Australian species of aerial mistletoes (Fig. 1), and some root hemiparasites (Exocarpos spp. and Anthobolus foveolatus) (Fig. 2). On the other hand, haustorial interfaces of the root hemiparasites Olax phyllanthi and Santalum (2 species) are comprised mainly of parenchyma, as opposed to terminating tracheads or vessels, implying that direct solution transfer between partners via vessels or tracheary elements may be limited (Fig. 3).

Resistant Genotypes

The dodders (Cuscuta spp.) are parasitic plants that feed on the stems of their host plants. Cuscuta campestris is one of the most damaging parasitic plants for the worldwide agricultural production of broad-leaved crops. Its control is limited or non-existent, therefore resistance breeding is the best alternative both economically and environmentally. Common vetch (Vicia sativa) and bitter vetch (Vicia ervilia) are highly susceptible to C. campestris, but no resistant genotypes have been identified. Thus, the aim of this study was to identify in V. sativa and V.ervilia germplasm collections genotypes resistant to C. campestris infection for use in combating this parasitic plant. Three greenhouse screening were conducted to: (1) identify resistant responses in a collection of 154 accessions of bitter vetch and a collection of 135 accessions of common vetch genotypes against infection of C. campestris; (2) confirm the resistant response identified in common vetch accessions; and (3) characterize the effect of C. campestris infection on biomass of V. sativa resistant and susceptible accessions. Most common vetch and bitter vetch genotypes tested were susceptible to C. campestris. However, the V. sativa genotype Vs.1 exhibited high resistance. The resistant phenotype was characterized by a delay in the development of C. campestris posthaustorial growth and a darkening resembling a hypersensitive-like response at the penetration site. The resistant mechanism was effective in limiting the growth of C. campestris as the ratio of parasite/host shoot dry biomass was more significantly reduced than the rest of the accessions. To the best or our knowledge, this is the first identification of Cuscuta resistance in V. sativa genotypes.

Attachment Strategies

Aims: We explored the relation between mothers’ protective attachment strategies and those of their school-age children. Methods: In total, 49 child–mother dyads participated in a short longitudinal study when the children were 5.5 and 6.0 years old. Their strategies were first assessed with the Preschool Assessment of Attachment (PAA) and then with the School-age Assessment of Attachment (SAA). Mothers were assessed with the Adult Attachment Interview (AAI). The Dynamic-Maturational Model of Attachment and Adaptation (DMM) was used to classify the assessments. Results: The validity and precision of the DMM-AAI were supported: Mothers’ AAI classifications were related to their referral group (normative or clinical) and measures of stress and distress. The DMM categories were more associated with risk than the Ainsworth categories. Types A, C and A/C were differentiated by trauma, triangulation and depression. Mothers’ and children’s protective attachment strategies were related, with B mothers having B children and A or C mothers having children using the same or opposite strategy. Children whose classification changed from the PAA to the SAA had mothers with complex traumas. Conclusion: When psychosocial treatment is needed, knowing whether mother and child use the same or different strategies and whether mothers have complex trauma can affect treatment success.
