Temperate and tropical lotus display high levels of genetic differentiation corresponding to ecological adaptation. Those genes contained in the highly differentiated genomic regions include those involving circadian clock and energy metabolism. Some of these candidate genes could be useful for molecular breeding of lotus lineages with long florescence in temperate zone.

Since phosphorus and salt stresses change ABA concentrations throughout the plant, wild-type and ABA-deficient mutant tomatoes were reciprocally grafted to compare local versus long-distance ABA effects. Rootstock genotype affected stomatal conductance, leaf area and shoot biomass, while scion genotype affected root biomass, by changing local ABA concentrations in distal tissues.

Maize PPR protein Defective kernel 6 was involved in RNA editing in mitochondria NADH dehydrogenase3 to correct Nad3 codons to conserved amino acids. Mutation in Dek6 decreased the activity of mitochondria NADH dehydrogenase complex I and led to the defective kernel phenotype of dek6.

AGO18b negatively regulates determinacy of spikelet meristems on the tassel central spike in maize

This study demonstrated that maize Argonaute (AGO) protein AGO18b is specifically enriched in the inflorescence meristem and axillary meristems of the tassel, and functions as a negative regulator of spikelet number on the tassel central spike by interacting with the microRNA166-mediated regulatory pathway.
