Development and Validation of Gene-Based SSR Markers in the Genus .

Bioinformatics tools have been employed for the direct development of gene-based simple sequence repeat (SSR) markers. Through the analysis of 28,056 expressed sequence tag (EST) sequences, a total of 5,851 ESTs containing SSRs were identified, amounting to approximately 17.07 Mb.

Mercury-induced oxidative stress in Indian mustard (Brassica juncea L.).

Mercury, a potent neurotoxin, is released to the environment in significant amounts by both natural processes and anthropogenic activities. No natural hyperaccumulator plant has been reported for mercury phytoremediation. Few studies have been conducted on the physiological responses of Indian mustard, a higher biomass plant with faster growth rates, to mercury pollution.

Bioaccumulation and physiological effects of mercury in Pteris vittata and Nephrolepis exaltata.

Anatomical, histochemical and biochemical approaches were used to study mercury uptake and phytotoxicity as well as anti-oxidative responses in two species of ferns [Chinese brake fern (Pteris vittata) and Boston fern (Nephrolepis exaltata)], grown in a hydroponic system. The roots of both cultivars accumulated large amounts of mercury, but exhibited limited mercury translocation to shoots. Mercury exposure led to more pronounced phytotoxicity accompanied by stronger oxidative stress in the shoots of P.

Phytotoxicity of mercury in Indian mustard (Brassica juncea L.).

This study investigated the phytotoxicity of mercury to Indian mustard (Brassica juncea L.). Two common cultivars (Florida Broad Leaf and Long-standing) were grown hydroponically in a mercury-spiked solution.
