Upland cotton has high yield and Island cotton has superior fiber properties. To introgress the good fiber quality from Island cotton into an Upland cotton variety, a high-density genetic linkage map, with 2,292 loci and covered 5,115.16cM of the cotton genome, was developed from an interspecific population.

The effects of pepc gene expression on Cyanobacteria photosynthesis have not been reported. This study found that PSI activity of Anabaena was inhibited and dark reduction of P700⁺ was stimulated in reverse mutant (down-regulated pepc), indicating enhanced cyclic electron flow around PSI and increased tolerances of temperature, pH and salinity .

In soybean-soybean mixed culture, transgenic soybean plants were much more competitive. In soybean-maize culture, transgenic soybean had no impact on maize growth, whereas soybean physiological traits could be easily affected by the mixed maize. Therefore, genetic modification of root traits might be a more suitable strategy for improving crop production.

This work shows that exogenous Ca²⁺ could help to protect the peanut photosynthetic apparatus from severe photoinhibition under heat and HI stress by accelerating the repair of Photosystem II center proteins.

It is largely a mystery that how immobile sperm cells of flowering plants get into fusions with the egg and central cells. Through live-cell imaging of the embryo sac, we show a dramatic release and re-adhesion of one sperm cell, modifying gamete associations and ensuring the success of double fertilization.

Rice spikelet has a distinct morphology, and its development determines rice grain yield. In this study, we showed that a monocot-specific MADS-box protein, OsMADS32 may interact with PI-like proteins OsMADS2 and OsMADS4 via its K domain in specifying lodicules and stamens development.
