Cryptic invasion by Capsella rubella in Chile detected by ARMS–PCR 
blank image
Sergio A. Castro and Roberto Ovalle
pp. 623-629

Cryptic species are morphologically similar species that tend to be recognised as a single species. Because the genus Capsella contains two cryptic species (C. bursa-pastoris and C. rubella), our aim was to establish the presence or absence of these exotic taxa in continental Chile. Using molecular markers, we confirm that both species of Capsella are present in continental Chile, although they exhibit different abundances and ranges.

Intermediate morphophysiological dormancy allows for life-cycle diversity in the annual weed, Turgenia latifolia (Apiaceae) 
blank image
Miregul Nurulla , Carol C. Baskin , Juan J. Lu , Dun Y. Tan and Jerry M. Baskin
pp. 630-637

Understanding the timing of seed germination of weeds requires information about the responses of seeds to the environment. We investigated seed dormancy in the weed Turgenia latifolia and found that it consists of two components, one of which could be broken at high and/or low temperatures, and the other, need for embryo growth inside the seed before germination, required low temperature. These results are used to explain how the species can behave as both a winter annual and a short-lived summer annual.

Monophyly of Verbascum (Scrophularieae : Scrophulariaceae): evidence from nuclear and plastid phylogenetic analyses 
blank image
Farrokh Ghahremaninejad , Mehrshid Riahi , Melina Babaei , Faride Attar , Lütfi Behçet and Ali Sonboli
pp. 638-646

Using four selected molecular markers (nrDNA ITS and the plastid spacers trnS/G, psbA-trnH and trnY/T), we present a phylogeny of Verbascum and test previous infrageneric taxonomic hypotheses as well as its monophyly with respect to Scrophularia. Our results show that while molecular data unambiguously support the circumscription of Verbascum inferred from morphology, they prove to be of limited utility in resolving infrageneric relationships, suggesting that Verbascum ‘s high species diversity is due to rapid and recent radiation.

Pleopeltis pleopeltifolia (Polypodiopsida, Polypodiaceae), a poikilochlorophyllous desiccation-tolerant fern: anatomical, biochemical and physiological responses during water stress 
blank image
Ana Paula Lorenzen Voytena , Bruno Degaspari Minardi , José Bonomi Barufi , Marisa Santos and Áurea Maria Randi
pp. 647-656

Epiphytic plants do not have direct connections with the ground. They use trees (phorophytes) as a support, and they are subject to recurrent dry periods. Pleopeltis pleopeltifolia is a poikilochorophyllous desiccation-tolerant (DT) epiphytic fern that has the ability to revive from the air-dry state. So as to better understand the mechanisms of DT in ferns, we carried out a study to analyse changes associated with desiccation and rehydration in P. pleopeltifolia.

Temperature influences stomatal density and maximum potential water loss through stomata of Dodonaea viscosa subsp. angustissima along a latitude gradient in southern Australia 
blank image
Kathryn E. Hill , Greg R. Guerin , Robert S. Hill and Jennifer R. Watling
pp. 657-665

The environment and climate that a plant lives in influence its physical traits, and they, in turn, influence plant function. This study investigated the impact of environmental and climatic pressures on the stomata of Dodonaea viscosa subsp. angustissima, so as to discover what environmental and climatic pressures exert greatest influence on stomatal properties. We found that maximum temperature exerted the greatest pressure on the stomata of this species.

Do CO2, temperature, rainfall and elevation influence stomatal traits and leaf width in Melaleuca lanceolata across southern Australia? 
blank image
Kathryn E. Hill , Robert S. Hill and Jennifer R. Watling
pp. 666-673

Stomata are the interface between the atmosphere and leaf internal spaces, and their size and density can vary with a range of environmental factors. We investigated these responses using Melaleuca lanceolata and found a relationship between stomatal traits and temperature, as well as between leaf width and elevation, rainfall and temperature. Knowledge of leaf plasticity enhances our understanding of how plants respond to changing environmental conditions.

Lost in time and space: re-assessment of conservation status in an arid-zone flora through targeted field survey 
blank image
J. L. Silcock , A. J. Healy and R. J. Fensham
pp. 674-688

Lack of basic data to assess plant species against IUCN Red List criteria is a major impediment to assigning accurate conservation status throughout large areas of the world. We systematically re-assessed the conservation status of an arid-zone flora using herbarium records, expert interviews and targeted field survey. This approach facilitates robust conservation assessments across vast and poorly known regions, distinguishing species that have been lost in space and time from those that are at risk of becoming lost from our landscape.

Morpho-anatomical and molecular characterisation of ectomycorrhizae associated with Eucalyptus species growing in different areas of the Punjab Province, Pakistan 
blank image
Hira Bashir and A. N. Khalid
pp. 689-697

Ectomycorrhizal symbiosis with exotic Eucalyptus species is widespread, especially in the semiarid areas compared with arid regions of Punjab Province, Pakistan. This study aims to identify ectomycorrhizal symbionts based on morphotyping and sequence analysis of the rDNA internal transcribed spacer (ITS) region and to assess their potential to colonise different Eucalyptus species. Fungal symbionts are characterised as having a broader host range or narrower host range. Results showed that only three fungal species are evidently colonising the roots of Eucalyptus plantations in the Punjab Province, which reveals that exotic plant species have a narrow host range.

Molecular cloning, expression and sequence analysis of a phenylalanine ammonia-lyase gene from Poncirus trifoliata under iron deficiency 
blank image
Jian-Fu Li , Wen-Jun Zheng , Li Zeng , Jian-Fu Liu and Ming-Yuan Wang
pp. 698-704

The PAL gene was cloned from Poncirus trifoliata and the sequence analysed using bioinformatics. The expression of pal1 was up-regulated in response to Fe deficiency. Phenolics played a crucial role in alleviation of iron stress in P. trifoliata.
