“…Our study demonstrated that moderate drought stress (50% Field Capacity, FC) reduced plant height (PHG) and leaf area (LAG) particularly on the generative phase, while severe drought stress (35% FC) had effect on both variables (PHV and LAV) since the vegetative phase (Figures 1A, 1B, and 1D), that similarly on curly chili presented by Widuri et al (2020). The study also found that other leaf parameters, such as cell area (CA) and stomatal length (SL) were detected to decrease in the generative phase (Figure 1D), that accordance with research in birdeye chili by (Lestari et al 2023). However, drought had less effect on chlorophyll contents throughout both the vegetative (CHLV) and generative phases (CHLG) (Figures 1A and 1D).…”

“…Each replication consisted of three plants, with one plant per polybag. Drought was imposed by maintaining the media water content at 50% Field Capacity (50% FC) (Equal to 1.46 MPa) as moderate drought stress and 35% FC (2.25 MPa) as severe drought stress, respectively (Okunlola et al 2017;Lestari et al 2023). The 80% FC (0.47 MPa) was used as a control to prevent the chili plants' roots from being submerged (Mardaninejad et al 2017).…”

“…The macropores of the media contain oxygen, while the micropores contain water (Lopez and Barclay 2017). The water content at field capacity was determined referred to Lestari et al (2023). The planting media was saturated with a particular volume of water.…”

“…The moisture content at field capacity was calculated as the difference in the weight of the media at field capacity and oven-dried media (7200 g/polybag-3200 g/polybag=4000 g/polybag). The weight of planting medium at 80% FC and 35% FC is calculated based on the volume of water at field capacity using the formula described by Lestari et al (2023) as follows: (i) Weight of medium at FC 80% (g/polybag) = (80% × water content at field capacity) + weight of oven-dried media. (ii) Weight of medium at FC 50% (g/polybag) = (50% × water content at field capacity) + weight of oven-dried media.…”

“…From each slide, three representative images were selected to observe the stomata length (SL) and cell area (CA). Leaf area (LA) was calculated using ImageJ (https://imagej.nih.gov/ij/) from a scan of the leaf blade recorded using a flatbed scanner HP Scanjet G3010 (Hewlett-Packard, California, USA) (Lestari et al 2023). The imageJ application was also used to estimate stomatal length (SL) in µm; choose and trace an outline around the perimeter of at least 50 pavements, including guard cells, to estimate the size of each cell.…”

Abstract. Istiqomah I, Isnansetyo A, Murwantoko, Handayani DP, Lestari YN, Taslihan A, Permana IGN, Wijayanti E. 2023. Antibiotic resistance of emerging pathogenic bacteria of hybrid grouper farming in Indonesia. Biodiversitas 24: 2493-2501. A hybrid grouper is among the main coastal farming species in Asian countries, yet vibriosis is still a significant issue. Therefore, a knowledge of pathogenic strains responsible for recent cases is essential for developing appropriate control measures. The purpose of the study was to describe emerging bacterial pathogens associated with hemorrhagic disorder, skin wounds, and mortality in cantang hybrid grouper farms in Indonesia. A total of 30 bacterial strains were recovered from the kidney of diseased grouper on TCBS agar. Based on the ability to induce clinical signs and mortality of grouper juveniles owing to intraperitoneal bacterial infection at 106 CFU/fish, the bacteria were divided into three groups: pathogenic (n=11), low-pathogenic (n=2), and non-pathogenic (n=17). The pathogenic strains were putatively identified as Photobacterium damselae subsp. damsela (n=8), Vibrio alginolyticus (n=1), Vibrio harveyi (n=2), and Vibrio azureus (n=2) based on the biochemical characteristics and 16S rRNA and DNA gyrase B subunit gene sequences. The pathogenic bacteria were sensitive to erythromycin, gentamycin, oxytetracycline, and kanamycin. However, it still has various resistant patterns to ampicillin, fosfomycin, chloramphenicol, streptomycin, rifampicin, and enrofloxacin. This study demonstrated the emergence of pathogenic P. damselae subsp. damselae, Vibrio alginolyticus, V. harveyi, and V. azureus in grouper aquaculture in Indonesia with multiple antibiotic resistance, which needed to further studies.

Drought, exacerbated by climate change, represents a growing challenge for agriculture, significantly impacting on crops such as chili peppers (Capsicum), essential in the global diet. This work evaluated the response to water stress by suspending irrigation in Siete Caldos chili pepper plants (Capsicum frutescens). Control plants were watered every 48 h, while stress was induced in the test plants by withholding irrigation for 14 days, followed by an evaluation of recovery through rehydration on day 15. Growth parameters such as the fresh weight of the aerial part, root length, and number of flower buds showed significant differences between the two groups from the eighth day onwards. However, physiologically and biochemically stress-induced decreased relative water content, membrane stability, and chlorophyll content, coupled with increased electrolyte leakage, proline content, and antioxidant activity (catalases and peroxidases), were observed starting on the third day. These effects were more severe on day 14. At the molecular level, the expression of stress response genes (AP2, LOX2, CAT, CuSOD, MnSOD, and P5CS) was quantified at days 3, 14, and 15, revealing differences in transcript levels between the treatments. Finally, rehydration in the stressed plants resulted in the recovery of the evaluated parameters and a survival rate of 100%. Therefore, chili pepper has tolerance mechanisms that allow it to withstand a period of 14 days without irrigation, without reaching its permanent wilting point, and it can recover if conditions improve. This study underscores the complexity of plant responses and tolerance mechanisms to drought, providing insights into the behavior of semi-domesticated species.
