Abstract:
... Leaf length and width are two of the most important components of rice (Oryza sativa L.) plant architecture and directly contribute to yield. The genetic effects of leaf length and width are controlled by quantitative trait loci (QTLs). In this study, a double haploid (DH) population derived from a cross of O. sativa subsp. japonica cultivar ‘Maybelle’ and subsp. indica cultivar ‘Baiyeqiu’ (‘BYQ’) ...

environmental factors; habitats; land restoration; lichens; organic matter; sand; sand fraction; secondary metabolites; soil pH; soil stabilization; species diversity; thin layer chromatography; usnic acid; Manitoba
Abstract:
... Many lichen secondary metabolites have functions related to the environmental conditions of lichen habitats but few studies have compared soil characteristics with lichen species composition or their secondary products. The goal of this study was to investigate the relationship between soil characteristics with lichen species composition and secondary metabolites. Five locations were chosen in Man ...

Quercus garryana; alleles; allelic variation; animals; climate change; ecosystems; flora; gene flow; genetic markers; habitats; loci; population structure; risk; temporal variation; tree and stand measurements; trees; British Columbia
Abstract:
... Garry oak (Quercus garryana Douglas ex Hook.) is a deciduous tree whose ecosystem is listed “at risk” throughout its range in British Columbia (BC), Canada, under the Canadian Species at Risk Act. Garry oak ecosystems host the most diverse flora for coastal BC, yet they account for less than 0.3% of the province’s land coverage. Due to the loss and degradation of Garry oak habitat, many associated ...

4. Species delimitation of some Argyreia (Convolvulaceae) using phenetic analyses: insights from leaf anatomical data reveal a new species

Subject:
Argyreia; cluster analysis; leaves; new species; peeling; principal component analysis; scientific illustration; species identification; taxon descriptions
Abstract:
... Argyreia Lour. is one of the most taxonomically complex genera of the morning glory family (Convolvulaceae). The number of named species is now 135, and new species are regularly being described. There are several species complexes that are morphologically similar and difficult to tell apart. Therefore, the aim of this study is to explore the species identification criteria for Argyreia, especiall ...

Abstract:
... Perforation formation in Aponogeton madagascariensis (Mirb.) H.Bruggen (lace plant) is an excellent model for studying developmentally regulated programmed cell death (PCD). In this study, we isolated and identified two lace plant vacuolar processing enzymes (VPEs) and investigated their involvement in PCD and throughout leaf development. Lace plant VPE transcript levels were determined during sev ...
