“…When wheat is infected with Puccinia striiformis f. sp. tritici ( Pst ) at high temperature, plants silenced with TaWRKY70 are highly susceptible to Pst , with decreased expression of ethylene and SA‐response genes TaPIE1 and TaPR1 , but unchanged of JA‐response genes AOS , indicating that TaWRKY70 acts as a positive regulator in the crosstalk between SA and ethylene signals (Wang et al ., 2020).…”

Summary Jasmonate (JA) and abscisic acid (ABA) are two major phytohormones involved in pathogen resistance. However, how their biosynthesis is regulated is not well understood. We silenced NaWRKY70 in wild tobacco Nicotiana attenuata and determined its role in regulating genes involved in the production of JA, ABA and the phytoalexin capsidiol in response to the fungal pathogen Alternaria alternata using techniques including electrophoretic mobility shift, chromatin immunoprecipitation, transient overexpression and virus‐induced gene silencing. Silencing NaWRKY70 dramatically reduced both basal and A. alternata‐induced jasmonoyl‐isoleucine (JA‐Ile) and ABA. Further evidence showed that NaWRKY70 directly binds to the W‐boxes of the promoters of NaAOS and NaJAR4 (JA biosynthesis), NaNCED1 and NaXD1‐like (ABA biosynthesis), and NaMPK4 (ABA signaling) to activate their expression, while binding but repressing the expression of NaCYP707A4‐like3 (ABA degradation). Additionally, NaWRKY70 regulates capsidiol production through its key enzyme genes NaEASs and NaEAHs, and interacts with its regulator NaERF2‐like to enhance their expression, whereas ABA negatively regulates capsidiol biosynthesis. Our results highlight the key role of NaWRKY70 in controlling both JA‐Ile and ABA production, as well as capsidiol production, thus providing new insight into the defense mechanism of plant resistance to A. alternata.

“…The PCA also confirms that the high germination ability of H. iraquensis is the primary characteristic distinguishing it from other species, while synchrony, without acronym calculated in H. salicornicum is the primary characteristic for the separation of this species from the others. Some scholars recently used PCA as an auxiliary tool to improve the discussion about clustering of species and treatments, involving both seed germination (Bhatt et al, 2019c; Calone et al, 2020; Liu et al, 2020; Wang et al, 2020) and morphophysiological characteristics (dos Santos et al, 2019; Pompelli et al, 2019; Adar et al, 2020; Corte-Real et al, 2020; Prabu et al, 2020).…”

Seed mass, dormancy and germinability variation among maternal plants of four Arabian halophytes

et al. 2022

Coastal desert vegetation of the Arabian Peninsula is almost entirely dominated by halophytes. Natural populations provide a genetic resource for ecological remediation and may also have direct economic value. High intrapopulation variation of seed traits is presumed to increase population persistence in the unpredictable climatic conditions of this hyper-arid desert. We investigated whether intrapopulation variation of seed mass, dormancy and germinability of four species was attributable to maternal individuals. Arthrocnemum macrostachyum, Halothamnus iraquensis, Haloxylon salicornicum and Seidlitzia rosmarinus are commonly distributed Arabian halophytes with differing seed weight variation. All species exhibited a higher germination when exposed daily to 12 h light, compared to seeds in darkness. A higher germination was correlated with a shorter germination time. For H. iraquensis and S. rosmarinus, a shorter germination time was negatively correlated with germination synchrony. H. salicornicum showed the highest intrapopulation variation of seed traits, followed by A. macrostachyum, S. rosmarinus and H. iraqensis. We found that individuals within populations of all the studied species showed variability in germination but the extent of variation was species-specific. The variation in seed mass and germination among the individuals of the studied species may facilitate a temporal distribution of germination, which may reduce the risk of seed bank exhaustion. The results of this study could assist conservation and management by improving the efficiency of seed collection from wild populations of these species.

“…They found that stress-responsive candidates had better protective mechanisms for adapting to climate change. Moreover, other drought-resistant oil crops, such as safflower and Jatropha curcas, represent alternatives for biodiesel production (Wang et al, 2020;Yesilyurt et al, 2020). However, in addition to feedstock availability, other aspects which cannot be circumvented when promoting the cultivation of these new types of crops include technology feasibility and the planting habits, capabilities and willingness of local farmers.…”
