SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1) encodes a MADS-box protein that plays an essential role in integrating multiple flowering signals to regulate the transition from vegetative to reproductive development in the model plant Arabidopsis. Although SOC1-like genes have been isolated in various angiosperms, its orthologs in Orchidaceae, one of the largest families of flowering plants, ...

BACKGROUND AND AIMS Increasing evidence challenges the conventional perception that orchids are the most distinct example of floral diversification due to floral or prezygotic isolation. Regarding the relationship between co-flowering plants, rewarding and non-rewarding orchids in particular, few studies have investigated whether non-rewarding plants affect the pollination success of rewarding ...

BACKGROUND Sexually deceptive orchids of the genus Ophrys mimic the mating signals of their pollinator females to attract males as pollinators. This mode of pollination is highly specific and leads to strong reproductive isolation between species. This study aims to identify candidate genes responsible for pollinator attraction and reproductive isolation between three closely related species, O...

Abstract Tropical xero-epiphytic orchids undergo a photosynthetic mechanism called ‘Crassulacean Acid Metabolism’, modification of Calvin–Benson cycle. This anabolic process aids in the long-term retention organically fixed CO 2 , imprinting them as active sequestrators and fixers gaseous . The malate decarboxylation competence enzymes—phosphoenolpyruvate carboxykinase (PEPCK), Nicotinamide Ade...

All orchids have showy flowers and many are therefore popular as exotic houseplants as well as contributing significantly to eco-tourism. A special attribute of some orchid genera is the production of edible tubers, an attribute that can contradict eco-tourism if harvesting is not done sustainably. Such is the case in the Southern Highlands where for example, Kitulo Plateau has been gazetted to...

The selection and validation of proper distinguishing characters are of crucial importance in taxonomic revisions. The modern classifications of orchids utilize the molecular tools, but still the selection and identification of the material used in these studies is for the most part related to general species morphology. One of the vegetative characters quoted in orchid manuals is leaf arrangem...

Spring temperature increases could differentially affect flowering times and pollinator flight periods, leading to asynchrony and reduced pollination. A specialist orchid-bee study combining herbarium, museum and field data shows that bee flight dates are advancing faster than orchid flowering, which could lead to significant future uncoupling.

Root endophytic fungi are essential to the life cycle of orchids. Many them act as growth promoters host plant and mycorrhizal endophytes indispensable seed germination. This study aimed evaluate cultivable fungal richness five native orchids rupestrian grasslands (campos rupestres) in Serra do Cipó, Brazil. Healthy roots were sampled isolated, from which total DNA was extracted Internal Transc...

Family Orchidaceae has 25.000 to 30.000 species which are divided into 5 subfamilies. Moon orchids and earth examples of plants from the family. Orchid cooperatives in Indonesia have high economic value. In cultivation orchids, there obstacles that occur, namely drought can inhibit growth. Drought stress causes a slow increase leaf area affects stomata or photosynthesis reduce speed plant produ...
