ABSTRACT Sorghum is an economically important crop for human consumption, animal feed and biomass production. However, its productivity affected by abiotic biotic stresses. Drought one of the major global problems due to alarming climate change. Plant growth‐promoting rhizobacteria (PGPR) help crops improve their resilience survival in water‐scarce environments. Therefore, present study aimed investigate potential rhizobacterial isolates sorghum tolerance drought other stress. The bacterial sample from different soil roots genotype was isolated locations Ethiopia using serial dilution techniques. biochemical properties these were evaluated. PGPR traits analysed under temperatures, pH, salinity Furthermore, isolates' performance evaluated four concentrations PEG (6000): (10%, 15%, 25% 32.6%), which induces osmotic stress reducing water availability, thus mimicking effects sorghum. PCR detection genes associated with stress, such as phosphate solubilisation, nitrogen fixation, ACC (1‐aminocyclopropane‐1‐carboxylate) deaminase phytohormone production performed designed primers. In addition, identification molecular characterisation PGPRs 16S ribosomal RNA (rRNA) gene‐specific Serial techniques resulted 210 isolates. Biochemical analysis revealed that 68 exhibited while 50 showed ability solubilise phosphate. amplification identified involved several isolates, suggesting they have tolerance. Among examined, nifH gene 16 acdS 10 pgg 21 these, Pseudomonas ms22 isolate a high promote growth greenhouse performance. our findings suggest harnessing could pave way environmentally friendly efficient agricultural practices conditions.

Some cereal crops can withstand harsh growing conditions, and, hence, be considered an important line of defense against food shortage under climate change. Sorghum ( bicolor (L.) Monech) is the main crop for millions people, especially in sub-Saharan Africa and South Asia. This performs well input constraints (e.g., limited water) exhibits high resilience to adverse conditions temperature, drought, waterlogging), making it a star combating hunger However, sorghum other similar are not tolerant absolute terms. Climate change could push these beyond limits they tolerate, jeopardizing security people around world. In this research, we analyzed current status production, trends, factors controlling yield using empirical approaches. Especially Africa, cultivated widely unfavorable sub-optimal levels. Our findings raise multiple concerns as highlight opportunities sustainability cultivation future with seems increase persistently despite global warming due improved inputs approach, offering hope that adaptation approaches fruitful, Africa. A combination interventions including adequate use fertilizers technology adoption cultivars), efficient management (e.g. irrigation), better agronomic practices, key boosting ensuring warmer climate.

The effects of combined (HT) during flowering stage were investigated. main objective was to assess foliar spray melatonin under both individual HT at stage. Drought stress imposed by withholding irrigation, whereas exposing plants an ambient temperature (AT)+5°C temperature. drought+HT first, followed exposure AT+5°C duration or 10 days. results showed that had a significant negative effect compared with alone. However, spraying 100 µM on challenged increase in total chlorophyll content [drought: 16%, HT: 14%, drought+HT: 11%], F v /F m 15%, 13%], relative water 10%, 2%, 8%], proline 26%, 17%, 14%] their respective control. Additionally, positively influenced stomatal trichome characteristics control plants. Also, osmotic adjustment found be significantly increased melatonin-sprayed plants, which, turn, resulted number fruits, fruit set percentage, yield. Moreover, also enhanced quality fruits through lycopene content, carotenoid titratable acidity, ascorbic acid Overall, this study highlights usefulness effectively mitigating drought, HT, stress, thus leading tolerance tomato.
