Heavy Metal Stress Alters the Response of the Unicellular Cyanobacterium Synechococcus elongatus PCC 7942 to Nitrogen Starvation

open access: yesLife, 2020
Non-diazotrophic cyanobacteria are unable to fix atmospheric nitrogen and rely on combined nitrogen for growth and development. In the absence of combined nitrogen sources, most non-diazotrophic cyanobacteria, e.g., Synechocystis sp.

A TIR-NLR gene from Arabidopsis Pla-1 confers resistance to geminivirus infection. [PDF]

open access: yesPlant J
SUMMARY Geminiviruses are single‐stranded DNA viruses that infect many plant species and cause serious losses in agronomically important crops. An earlier study showed that the Arabidopsis thaliana ecotype Pla‐1 is resistant to infection by diverse geminivirus species and mapped the major resistance locus Geminivirus Resistance of Pla‐1 1 (GRP1) to ...

Jasmonates enhance plants tolerance grown in Cd‐contaminated environments: A comprehensive overview

open access: yesAnnals of Applied Biology, EarlyView.
Jasmonates (JAs) enhance plant tolerance to cadmium (Cd) stress by activating antioxidant defences but may reduce Cd uptake, limiting their effectiveness for phytoremediation. This review compiles studies that evaluated the effects of JA application on plants grown in Cd‐contaminated environments. Abstract Cadmium (Cd) is a toxic heavy metal and one of

‘Candidatus Phytoplasma solani’: From infection to all‐round characterisation of distinct tuf‐type strains with different virulence in tomato plants

open access: yesAnnals of Applied Biology, EarlyView.
‘Candidatus Phytoplasma (Ca. P.) solani’ is associated with bois noir (BN) of grapevine and stolbur of solanaceous plants and is primarily transmitted by Hyalesthes obsoletus Signoret. Four tuf‐a and five tuf‐b1 ‘Ca. P. solani’ strains were transmitted to tomato plants (cv. Micro‐Tom) by using bait‐plants and by capturing H.

Manganese Toxicity in Sugarcane Plantlets Grown on Acidic Soils of Southern China. [PDF]

open access: yesPLoS ONE, 2016
Ratoon sugarcane plantlets in southern China have suffered a serious chlorosis problem in recent years. To reveal the causes of chlorosis, plant nutrition in chlorotic sugarcane plantlets and the role of manganese (Mn) in this condition were investigated.
