“…Hemerocallis (daylily) has been cultivated as an edible, medicinal and ornamental plant for many centuries in its natural Far Eastern range. In Europe and North America, introduced Hemerocallis have only received major horticultural attention in the past 120 years (Rodriguez‐Enriquez and Grant‐Downton, ). The first report of a mysterious foliar disease, ‘spring sickness’, appeared in the 1970s in the USA, and it became increasingly problematic in cultivated hybrids, yet no similar disease has been reported from the natural range of Hemerocallis .…”

Plant pathology has a long-standing tradition of classifying microbes as pathogens, endophytes or saprophytes. Lifestyles of pathogens are categorized as biotrophic, necrotrophic or hemibiotrophic. Botrytis species are considered by many to be archetypal examples of necrotrophic fungi, with B. cinerea being the most extensively studied species because of its broad host range and economic impact. In this review, we discuss recent work which illustrates that B. cinerea is capable of colonizing plants internally, presumably as an endophyte, without causing any disease or stress symptoms. The extent of the facultative endophytic behaviour of B. cinerea and its relevance in the ecology and disease epidemiology may be vastly underestimated. Moreover, we discuss the recent discovery of a novel Botrytis species, B. deweyae, which normally grows as an endophyte in ornamental daylilies (Hemerocallis), but displays facultative pathogenic behaviour, and is increasingly causing economic damage. We propose that the emergence of endophytes 'gone rogue' as novel diseases may be related to increased inbreeding of hybrid lines and reduced genetic diversity. These observations lead us to argue that the sometimes inflexible classification of pathogenic microbes by their lifestyles requires serious reconsideration. There is much more variety to the interactions of Botrytis with its hosts than the eye (or the plant pathologist) can see, and this may be true for other microbes interacting with plants.

Hemerocallis spp. commonly known as daylilies and night lilies, are among the most popular ornamental crops worldwide. In Eastern Asia, H. citrina is also widely cultivated as both a vegetable crop and for medicinal use. However, limited genetic and genomic resources are available in Hemerocallis. Knowledge on the genetic diversity and population structure of this species-rich genus is very limited. In this study, we reported transcriptome sequencing of H. citrina cv. 'Datonghuanghua' which is a popular, highyielding variety in China. We mined the transcriptome data, identified and characterized the microsatellite or simple sequence repeat (SSR) sequences in the expressed genome. From ∼14.15 Gbp clean reads, we assembled 92,107 unigenes, of which 41,796 were annotated for possible functions. From 41,796 unigenes, we identified and characterized 3,430 SSRs with varying motifs. Forty-three SSRs were used to fingerprint 155 Hemerocallis accessions. Clustering and population structure analyses with the genotypic data among the 155 accessions reveal broader genetic variation of daylilies than the night lily accessions which form a subgroup in the phylogenetic tree. The night lily group included accessions from H. citrina, H. lilioasphodelus, and H. minor, the majority of which bloom in the evening/night, whereas the ∼100 daylily accessions bloomed in the early morning suggesting flowering time may be a major force in the selection of night lily. The utility of these SSRs was further exemplified in association analysis of blooming time among these accessions. Twelve SSRs were found to have significant associations with this horticulturally important trait.

A n o t a c i j aLietuviško viendienės genties augalų morfologinių ir dekoratyvių savybių aprašo iki šiol nebuvo. Šis morfologinių savybių aprašas, paruoštas atsižvelgiant į tarptautinių organizacijų -Naujų veislių apsaugos sąjungos UPOV (Union pour la Protection des Obtentions Végetales), Amerikos viendienių draugijos AHS (American Hemerocallis Society) ir tarptautinės biologinės įvairovės BI (Bioversity International) -reikalavimus ir yra reikalingas lietuviškų viendienių veislių morfologinėms augalo dalims aprašyti.Reikšminiai žodžiai: morfologinės savybės, viendienės. ĮVADASViendienė (Hemerocallis L.) -žolinis daugiametis dekoratyvus augalas, tinkantis įvairios paskirties želdynuose. Jas Hemerocallis vardu pavadino K. Linėjus (C. Linanaeus) apie 1735-1737 m. (Рycинoвa, 2005); graikiškai hemera -diena, kallos -grožis (Jankevičienė, 1998). J. Pabrėža pirmasis lietuviškai pavadino šį augalą viendienės vardu. Viendienės Lietuvoje dar vadintos lelijomis (dėl panašumo į lelijų žie-dus), kalavijais, kasočiais, teleponais (Dzūkija), aplelijomis (Šiaurės rytų Lietuva) ir kitais vardais (Andriušytė ir kt., 2008; Bertašiūtė ir kt.,
