Light quality and plant growth regulators influence pigment production in Alternanthera brasiliana calli

Alternanthera brasiliana is a medicinal plant with several popular use and high production of betalains. The aim of the present research was to establish a protocol for callus induction and betalain biosynthesis in A. brasiliana species, as well as to investigate the effect of different qualities of light in increasing betalain in A. brasiliana callus cultures. In this way, the callus initiation and the improvement of...

Simple sequence repeat (SSR) markers linked to drought tolerant traits in selected Sudanese rice (Oryza sativa L.) genotypes

Rice growth and productivity are affected by biotic and abiotic stresses; key among them being drought. Conventional breeding for drought tolerance is slowed down by the complex nature of mechanisms underlying this stress although molecular markers offer a promising approach. Plant exposure to drought stress leads to a significant effect in chlorophyll content and reduction in photosynthesis. In this study, 23 Sudanese...
