Maternal drought stress induces abiotic stress tolerance to the progeny at the germination stage in sunflower

Discrimination of Mung Bean (<i>Vigna Radiata</i> L.) Genotypes Exposed to PEG-Induced Water Deficit Reveals the Selection Criteria for Improved Breeding from Germination to Seedling Development

“…The inter-cluster distance was greater than the intra-cluster distances, suggesting that the diversity between clusters was greater than the other clusters. It was revealed that the most divergent cluster was Cluster I as it had the highest inter-cluster distance compared with other clusters, which ranged from 16 to 16.5, indicating that the genotype in Cluster I was distinctly different from others. However, the highest distance was obtained between Clusters I and III (16.50), signifying the extensive genetic divergence between these two clusters, which was followed by Clusters I and II (16.35), as well as Clusters I & IV (16.33).…”

“…It contains an essential source of plant protein (24-26%) for the vegetarian diet. Its cultivation largely depends on monsoon rains, but low rainfall particularly during March-May impedes its normal growth and development [16]. So far, the genetic variation present in the diverse gene pool is utilized inadequately in different studies of mung bean germplasms.…”

Impact of climate perturbations on seeds and seed quality for global agriculture

“…Instead, strong seed dormancy in sunflower is considered to be a serious constraint in seed production [17]. The dormancy of sunflower seeds is partly due to an inhibitory action of the envelopes ( pericarp and seed coat), but exposing seeds to different treatments can reduced it, and improve germination [18]. Thus, primary dormancy is caused by the physiological, morphological and/or physical characteristics of the seeds, which are genetically determined.…”

“…One the one hand, drought stress during seed development can decrease seed vigor [53][54][55]. On the other hand, it has also been shown to improve seed vigor of the progeny [18,56,57] (Figure 2). This detrimental/beneficial effect on seed germination probably relies on the level and duration of drought stress but also on the time window at which drought stress is applied on the mother plant, as evidenced by Vancostenoble et al [18].…”

Editorial: Seed-environment interactions

“…With the change of global climate, including drought and water shortage, high temperature or extreme cold, acid rain, ozone and ultraviolet radiation, etc. ( Li et al., 2011 ; Leisner et al., 2017 ; Lamichhane et al., 2018 ; Nguyen et al., 2021 ; Vancostenoble et al., 2022 ), the soil environment has also undergone great changes, such as the increase of saline-alkali land in the north, and the severe acidification of the soil in parts of the south ( Footitt and Cohn, 1992 ; Olsson and Kellner, 2002 ; Roem et al., 2002 ; Lowell et al., 2021 ). In this context, what physiological and molecular changes occur or what coping strategies are activated during the interaction of seeds with the environment, as seeds are self-sufficient biological entities capable of persevering in harsh environments?…”
