Monoseeding Increases Peanut (<i>Arachis hypogaea</i> L.) Yield by Regulating Shade-Avoidance Responses and Population Density

We aimed to elucidate the possible yield-increasing mechanisms through regulation of shade-avoidance responses at both physiological and molecular levels under monoseeding. Our results revealed that monoseeding decreased the main stem height but increased the main stem diameter and the number of bra...

Our results revealed that monoseeding decreased the main stem height but increased the main stem diameter and the number of branches and nodes compared to the traditional double- and triple-seeding patterns. The chlorophyll contents were higher under monoseeding than that under double- and triple-seeding. Further analysis showed that this, in turn, increased the net photosynthetic rate and reallocated higher levels of assimilates to organs. Monoseeding induced the expression patterns of Phytochrome B (Phy B) gene but decreased the expression levels of Phytochrome A (Phy A) gene. Furthermore, the <i>bHLH</i> transcription factors (<i>PIF 1</i> and <i>PIF 4</i>) that interact with the phytochromes were also decreased under monoseeding. The changes in the expression levels of these genes may regulate the shade-avoidance responses under monoseeding. In addition, monoseeding increased pod yield at the same population density through increasing the number of pods per plant and 100-pod weight than double- and triple-seeding patterns. Thus, we inferred that monoseeding is involved in the regulation of shade-avoidance responsive genes and reallocating assimilates at the same population density, which in turn increased the pod yield.Tingting ChenJialei ZhangXinyue WangRuier ZengYong ChenHui ZhangShubo WanLei ZhangMDPI AGarticle<i>Arachis hypogaea</i> L.monoseedingshade-avoidance responsesphytochromesBotanyQK1-989ENPlants, Vol 10, Iss 2405, p 2405 (2021)
