It is being confirmed previously the atmospheric nitrogen fixing ability of the cold adapted Pseudomonas migulae S10724 strain at the fluctuating temperatures. Therefore, net house bioinoculation experiment was performed to determine the effectiveness of inoculation of strain S10724 on the growth enhancement of native green gram (Vigna radiata L. Wilczek). The strain significantly (p < 0.05) stimulated the growth of roots (45.3 %) and shoots (45.6 %) of green gram plants. Furthermore, other growth related parameters viz. fresh and dry weight was also found to be increased significantly. Treated plants typically showed more obvious modifications in their biochemical status also. The total chlorophyll and nitrate reductase activity was increased in S10724 inoculated plant as compared to the control one. Moreover, in vitro seed germination assay revealed that the germination was increased in S10724 strain treated seeds by 22 % at 25 °C while 25 % at 12 °C unlikely to respective controls. The results suggest that P.migulae S10724 strain is a potential plant growth promoting bacterium for legume under fluctuating temperature ranges and therefore, could be used effectively as a low cost bioinoculant in Himalayan agricultural belt successfully.

Thermopile sensor arrays provide a sufficient counterbalance between person detection and localization while preserving privacy through low resolution. The latter is especially important in the context of smart building automation applications. Current research has shown that there are two machine learning-based algorithms that are particularly prominent for general object detection: You Only Look Once (YOLOv5) and Detection Transformer (DETR).

not only damages plant leaves directly but also causes a sooty blotch due to the honeydew secreted by the nymphs and adults. This pest is widespread and seems to be spreading from low latitude to higher latitude areas where winters are typically colder, indicating an increase in its cold tolerance. Changes in temperature help insects to anticipate the arrival of winter, allowing them to take defensive measures in advance.

The fall armyworm, , is one of the most notorious pest insects, causing damage to more than 350 plant species, and is feared worldwide as an invasive pest species since it exhibits high adaptivity against environmental stress. Here, we therefore investigated its transcriptome responses to four different types of stresses, namely cold, heat, no water and no food. We used brain samples as our interest was in the neuroendocrine responses, while previous studies used whole bodies of larvae or moths.

Background/objectives: Cold stress poses a significant threat to Asian rice cultivation, disrupting important physiological processes crucial for seedling establishment and overall plant growth. It is, thus, crucial to elucidate genetic pathways involved in cold stress tolerance response mechanisms.
Methods: We mapped , a ()-type homolog of rice, to a low-temperature seedling survivability (LTSS) QTL and used genomics, molecular genetics, and physiological assays to assess its role in plant resilience against low-temperature stress.
