Scientific information on the A genome species of Gossypium is limited due to their decline as crop species and low levels of marker polymorphism. As the A subgenome of the allotetraploid species of Gossypium is contributed by A genome progenitors, studies on the A genome will help us understand the evolution of polyploids. We compared DNA marker order along the chromosomes of A, D and At genom...

NAC proteins are plant-specific transcription factors that play essential roles in regulating development and responses to abiotic and biotic stresses. We show that over-expression of the cotton GhNAC2 under the CaMV35S promoter increases root growth in both Arabidopsis and cotton under unstressed conditions. Transgenic Arabidopsis plants also show improved root growth in presence of mannitol a...

Reniform nematode (Rotylenchulus reniformis) is a major pest of cotton in the southeastern United States. The objective of this study was to examine the variation of reniform nematode populations from cotton-growing locations in the United States where it is prevalent. Multivariate analysis of variance and discriminant analysis were used to determine the variability of morphology in males and i...

In the Sudano-sahelian zone, which includes Northern Cameroon, the inter-annual variability of the rainy season is high and irrigation is scarce. As a consequence, bad rainy seasons have a massive impact on crop yield. Traditional insurances, which would mitigate such impact, suffer from asymmetric information. They are based on crop damage assessment leading to high transaction costs compared ...

Abstract Background In plants, 14-3-3 proteins, also called GENERAL REGULATORY FACTORs (GRFs), encoded by a large multigene family, are involved in protein–protein interactions and play crucial roles various physiological processes. No genome-wide analysis of the GRF gene family has been performed cotton, their functions flowering largely unknown. Results this study, 17, 31, 17 genes were ident...

A new phenylbutanone glucoside, dorycnioside, was isolated from the methanol extract of the aerial parts of Dorycnium pentaphyllum subsp. herbaceum Vill. (Rouy) and identified as 4-(4'-O-beta-D-glucopyranosyl-3',5'-dimethoxyphenyl)-2-butanone (1). In addition, two known phenylbutanone glucosides, five flavonoids, one cyanogenic glucoside, one cyclitol and one hydroquinone glucoside were also is...

In resource-poor environments, adjustment in plant biomass allocation implies a complex interplay between environmental signals and plant development rather than a delay in plant development alone. To understand how environmental factors influence biomass allocation or the developing phenotype, it is necessary to distinguish the biomass allocations resulting from environmental gradients or onto...

Abstract Background Plant pollen has diverse morphological characteristics that can be consistently passed down from generation to generation. Information on morphology is thus immensely important for plant classification and identification. In the genus Gossypium , however, in-depth research lacking, with only few reports limited cotton species. To evaluate diversity of in we therefore conduct...
