Abstract Arabidopsis sepals coordinate flower opening in the morning as ambient temperature rises; however, underlying molecular mechanisms are poorly understood. Mutation of one heat shock protein encoding gene, HSP70-16 , impaired sepal stress responses (HSR), disrupting lipid metabolism, especially cuticular lipids, leading to abnormal opening. To further explore, what extent, lipids play ro...

BACKGROUND Stelis (Orchidaceae) encompasses approximately 1100 species of epiphytic orchids distributed throughout the Neotropics, with the highest diversity in Andean South America. Sixty-two species were recorded previously in Mexico. METHODS We formally describe here Stelis zootrophionoides as a new species from Chiapas, Mexico. To determine its systematic position, we conducted a morpholo...

BACKGROUND AND AIMS The first documented observation of pollination in Pleurothallidinae was that of Endrés, who noticed that the 'viscid sepals' of Specklinia endotrachys were visited by a 'small fly'. Chase would later identify the visiting flies as being members of the genus Drosophila. This study documents and describes how species of the S. endotrachys complex are pollinated by different D...

Phalaenopsis has a zygomorphic floral structure, including three outer tepals, two lateral inner tepals and a highly modified inner median tepal called labellum or lip; however, the regulation of its organ development remains unelucidated. We generated RNA-seq reads with the Illumina platform for floral organs of the Phalaenopsis wild-type and peloric mutant with a lip-like petal. A total of 43...

We studied the suitability of municipal solid waste compost (MSWC) application to submerged rice paddies in the perspective of metal pollution hazards associated with such materials. Experiments were conducted during the wet seasons of 1997, 1998 and 1999 on rice grown under submerged condition, at the Agriculture Experimental Farm, Calcutta University at Baruipur, West Bengal, India. The treat...

the purpose in this research was to study the effects of vermicompost and poultry manure on yield and yield components of the medicinal plant coriander (coriandrum sativum l.) in the shahr-e- ghods region. a factorial experiment using the randomized complete block design with three replications was conducted in the islamic azad university of shahr-e- ghods. the first factor was three levels of ...
