This study aims to unravel the molecular-physiological basis of salt response in ancient emmer and spelt wheats. Effects of prolonged salt exposure (0, 75, and 150mM NaCl) on 18 modern and ancient tetraploid and hexaploid wheat genotypes were initially investigated in a pot experiment. Responses of a selection of four genotypes in a field experiment and expression of SOS1 and NHX1 ion-transporter genes in a hydroponic experiment were then assessed under 150mM NaCl. Salinity led to suppressions in relative water content (RWC), chlorophyll, carotenoids, K+ , grain yield, and biomass, though it increased Na+ , proline, H2 O2 , malondialdehyde, and activity of antioxidative enzymes. Accumulation of Na+ in the ancient emmer genotypes was substantial. But, emmer genotypes suffered less from salinity, as they maintained chlorophyll, biomass, and grain yield/plant. Emmer outranked durum, bread, and spelt wheats in terms of expression of SOS1 and NHX1 ion-transporter genes, confirming possession of an enhanced Na+ compartmentalization capability.

In this study, we investigated the impacts of exogenously supplemented sodium nitroprusside (SNP), a NO donor, on drought tolerance and physio-biochemical mechanisms mediated by NO that influence nutrient contents and growth of gazania (Gazania rigens ). In a lath house, plants at the four-leaf stage were treated with a foliar spray of SNP (100μM) under two watering conditions: (1) 50% field capacity (drought stress);and (2) 100% field capacity (normal-watering). Results revealed that water deficiency significantly reduced gaseous exchange, chlorophyll pigments, water relations, NO, and proline contents. However, supplementation with NO increased proline levels and antioxidant enzyme activities, leading to improved photosynthesis, water relations, and drought tolerance by reducing lipid peroxidation and hydrogen peroxide levels. Furthermore, enhanced NO levels from SNP treatment promoted the accumulation of essential nutrients resulting in improved growth and biomass in gazania plants. Our results indicated that SNP supplementation increased gaseous exchange (21-53%), chlorophyll pigments (30-70%), water status (12-31%), antioxidant enzyme activities (19-52%), nutrient uptake (22-36%), and flower yield (49%), potentially mitigating the negative effects of water deficiency in gazanias under drought stress.

Members of the bHLH IIIf subfamily play an important role in trichome development, and ZabHLH22 , ZabHLH110 , ZabHLH161 , and ZabHLH194 , which belong to this subfamily, were selected as candidate genes. Chromosomal localization analysis showed that 165 of 195 ZabHLHs were unevenly distributed on 31 chromosomes, and 30 ZabHLHs were localized to unanchored scaffolds. The expansion of ZabHLHs mainly includes dispersed replication and whole-genome duplication or segmental replication. Fourty-seven cis -acting elements were predicted in the promoters of ZabHLHs , with hormone-responsive elements being the most abundant. Expression profiles of four candidate genes were analyzed in two Z. armatum cultivars. Trichome development is regulated by hormones such as methyl jasmonate, salicylic acid, and auxin. The qRT-PCR results indicate that four candidate genes respond to the stress induced by these three hormones.
