Differential Impact of Acclimation and Acute Water Deprivation in the Expression of Key Transcription Factors in Soybean Roots

Abstract

Soybean (Glycine max) is one of the major world commodities. In order to increase the soybean yields, it has been searched drought-tolerant cultivars, once the drought is the major constraint to soybean grown. Therefore, it is crucial to elucidate the molecular mechanisms associated with drought tolerance. Here, the in silico approach allowed us to identify 12 genes belonging to six different transcription factor families in soybean that have been associated with key events on drought response. The expression pattern of each gene was investigated by qPCR in root samples of drought-sensitive and drought-tolerant cultivars undergoing drought stress in potbased (PSys) and hydroponic (HSys) cultivation systems. GmaxMYC2-like 2 was induced under abrupt drought conditions in HSys in both cultivars, whereas GmaxAREB1-like 1 Fábia Guimarães-Dias and Anna C. Neves-Borges contributed equally to this work.

Jasmonic Acid Boosts Physio-Biochemical Activities in Grewia asiatica L. under Drought Stress

“…Several species have been found to suffer negative effects from moderate drought stress, including Phaseolus vulgaris [ 53 ], Vaccinium corymbosum [ 54 ], Malus domestica [ 55 ], and Punica granatum [ 56 ]. Following 20 days of water restriction, as we reported, severe drought stress resulted in plant growth reduced by five times in G. asiatica plants, which was also previously reported in sunflower [ 57 ], soybeans [ 58 ], and Zanthoxylum acanthopodium [ 59 ].…”
