“…It is possible that BRs play an important role in downregulating some responses to ABA, or when BRs are lacking, may amplify or modify the ABA signal. However, another study suggested that ABA and BR both enhance drought tolerance in sorghum (Sorghum vulgare) (Xu et al, 1994).…”

“…It has been shown that BRs play a role in down-regulating some responses to ABA, or when BRs are lacking, may amplify or modify the ABA signal. However, another study suggested that ABA and BRs both enhanced drought tolerance in sorghum (Xu et al, 1994). Taken together, these researches implicate that the complex interactions between BRs and ABA may exist in plants.…”

“…Our ordered seed weight measurements suggest instead that the increases in seed weight resulted from enhanced filling of the seed with sucrose and other sugars transported to them from the leaves. Spray application of epibrassinolide to sorghum plants at the heading and grain filling stages has been reported to have similar effects (Xu, 2007). However, it is also possible that the weak pAS activity in the seed coat also had an effect on the weight (Schruff et al, 2006).…”

Genes controlling hormone levels have been used to increase grain yields in wheat (Triticum aestivum) and rice (Oryza sativa). We created transgenic rice plants expressing maize (Zea mays), rice, or Arabidopsis thaliana genes encoding sterol C-22 hydroxylases that control brassinosteroid (BR) hormone levels using a promoter that is active in only the stems, leaves, and roots. The transgenic plants produced more tillers and more seed than wild-type plants. The seed were heavier as well, especially the seed at the bases of the spikes that fill the least. These phenotypic changes brought about 15 to 44% increases in grain yield per plant relative to wild-type plants in greenhouse and field trials. Expression of the Arabidopsis C-22 hydroxylase in the embryos or endosperms themselves had no apparent effect on seed weight. These results suggested that BRs stimulate the flow of assimilate from the source to the sink. Microarray and photosynthesis analysis of transgenic plants revealed evidence of enhanced CO 2 assimilation, enlarged glucose pools in the flag leaves, and increased assimilation of glucose to starch in the seed. These results further suggested that BRs stimulate the flow of assimilate. Plants have not been bred directly for seed filling traits, suggesting that genes that control seed filling could be used to further increase grain yield in crop plants.
