“…Besides environmental issues, edaphic elements also have remarkable influence on plant growth and development [32] as soil nutrient availability is one of the absolute needs of plants [33,34]. But imbalances or deviations of these prime requirements from the optimum levels create stresses causing disruption in the physiological functioning, break down the hormonal balance and ultimately assert negative impact on crop yield and produce quality [35,36,37].…”

This study evaluated the exogenous application of PGRs substitute chemical fertilization without compromising the growth and yield of tomato in fluctuated day-night temperature and humidity stressed late winter. Two-factor experiment comprising chemical fertilizers at 100, 110, 90 and 80 % of recommended doses besides control and PGRs of GA3; NAA, 4-CPA and SA @ 50 ppm including control was conducted where treatments were assigned in triplicates. Results revealed no significant variation among the fertilizer doses (80% to 110% of recommendation) regarding growth and yield contributing traits while among the PGRs, GA3 @ 50 ppm produced maximum number of flower clusters plant-1 (16.85), flowers (8.80) and fruits (5.79) cluster-1, single fruit weight (67.83 g) and fruit yield (6.61 kg plant-1) of tomato that was statistically identical with the findings of SA. But significant reduction in yield was noted in NAA and 4-CPA (1.20 kg and 1.21 kg plant-1, respectively). Interestingly, GA3 and SA in combination with any doses of the studied fertilizers maximize the tomato morphological and reproductive traits while fertilizer plus NAA and 4-CPA interaction gave the inferior results. Further, correlation matrix and PCA findings revealed that five fertilizer doses have no distinctiveness whereas GA3 and SA has distinct position than other PGRs with the maximum dependent variables those were contributed positively in the total variations. The study findings suggested that 20% fertilizer requirement could be reduced with the substitution of GA3 and SA @ 50 ppm for successful cultivation of tomato in late winter having the extreme environmental issues.

“…Plants are sessile organisms that cannot escape from HS like animals and thus have evolved a set of stress response mechanisms involving signalling cascade caused by inward flux of calcium (Saidi et al 2011; Mittler et al 2012), plant hormone signal transduction and reactive oxygen species (ROS) signal transduction and so on, to prevent heat damage and enhance their thermotolerance (He et al 2005; Pucciariello et al 2012; Arnao and Hernández‐Ruiz, 2018; Masaaki et al 2021; Akanksha et al 2023). These response pathways enhance thermotolerance by regulating a series of HS‐responsive genes or transcription factors (TFs).…”

High‐temperature stress (HS) is a major abiotic stress that affects the yield and quality of plants. Cathepsin B‐like protease 2 (CathB2) has been reported to play a role in developmental processes and stress response, but its involvement in HS response has not been identified. Here, overexpression, virus‐induced gene silencing (VIGS)and RNA‐sequencing analysis were performed to uncover the functional characteristics of SlCathB2‐1 and SlCathB2‐2 genes for HS response in tomato. The results showed that overexpression of SlCathB2‐1 and SlCathB2‐2 resulted in reduced heat tolerance of tomato to HS while silencing the genes resulted in enhanced heat tolerance. RNA‐sequencing analysis revealed that the heat shock proteins (HSPs) exhibited higher expression in WT than in SlCathB2‐1 and SlCathB2‐2 overexpression lines. Furthermore, the possible molecular regulation mechanism underlying SlCathB2‐1 and SlCathB2‐2‐mediated response to HS was investigated. We found that SlCathB2‐1 and SlCathB2‐2 negatively regulated antioxidant capacity by regulating a set of genes involved in antioxidant defence and reactive oxygen species (ROS) signal transduction. We also demonstrated that SlCathB2‐1 and SlCathB2‐2 positively regulated ER‐stress‐induced PCD (ERSID) by regulating unfolded protein response (UPR) gene expression. Furthermore, SlCathB2‐1 and SlCathB2‐2 interacting with proteasome subunit beta type‐4 (PBA4) was identified in the ERSID pathway using yeast two‐hybrid (Y2H) analysis and bimolecular fluorescence complementation (BiFC) screening. Overall, the study identified both SlCathB2‐1 and SlCathB2‐2 as new negative regulators to HS and presented a new HS response pathway. This provided the foundation for the construction of heat‐tolerant molecular mechanisms and breeding strategies aiming to improve the thermotolerance of tomato plants.

This study presents a comprehensive analysis of the influence of ENSO events on soil moisture, rainfall, and soybean crop yields, alongside an evaluation of trends and their correlations with soybean crop yield. Marathwada and Vidarbha regions, contributing 39% of India's soybean production, were found to be highly susceptible to El Niño events especially western and central parts of this region. El Niño negatively affected crop yield, with reductions ranging from − 12% to -70%, including − 7% to -40% rainfall decreases and − 2% to -6% lower soil moisture. During a very strong El Niño year, Marathwada experienced a 40% rainfall deficit and a 70% crop yield decline, while Vidarbha had a 7% rainfall deficit and a 57% crop yield reduction. Soil moisture trends indicated declining levels in Vidarbha during critical soybean growth months (June and August), whereas Marathwada showed no significant trend. Rainfall trends revealed an increase in September in Marathwada, affecting crop maturity, while Vidarbha had a beneficial rainfall trend in July, promoting crop growth and soil moisture. Correlations between soil moisture, rainfall, and soybean yield varied, with Marathwada exhibiting correlations of 0.58 for soil moisture and 0.56 for rainfall, and Vidarbha displaying a correlation of 0.29 for soil moisture and 0.53 for rainfall.
