Maize (Zea mays L.) is one of the staple foodstuffs of the cereal group which has a high percentage of carbohydrates, protein, and others. In 2050, maize is expected to double in demand, however, productivity must be balanced with the support management of diseases and pests of maize. Common maize disease is Downy mildew caused by Peronosclerospora spp., this disease attacks the leaves and seeds with 100% damage. This research aimed to determine the pathogenicity and resistance of Talenta, Pioneer 21, and Tamara maize varieties, by using in vivo leaf insertion and leaf spray methods. Fungal isolates were isolated from threshing conidia from maize leaves in the Sleman area field. Observation of fungal pathogenicity and maize resistance was measured based on symptom scale per two days of test and observation of leaf anatomy 45 days after planting. Calculation of fungal pathogenicity against maize varieties used growth analysis, disease incidence, disease severity, Area Under the Disease Progress Curve (AUDPC), and severity unit per time. The result of this research showed that Talenta was moderately resistant, Pioneer-21 was resistant, and Tamara was susceptible to Downy mildew. Downy mildew pathogenicity rate reached 0,07 units/day. Downy mildew infection reached epidermis tissue through stomata on maize leaves.

Abstract: Endophytic fungi were known in bioethanol industries due to their role in secreting secondary metabolites in the form of cellulolytic enzymes, which were known to be superior to bacteria. The secretion of metabolic enzymes depended on the host they invaded. Herbal plants were recognized as habitats for various endophytic fungi. Betel leaf (Piper betle L.) was one such herbal plant known for its high metabolite content. The aim of this study was to identify endophytic fungi living on betel leaf, conduct cellulolytic tests on the identified fungi, and determine which fungi exhibited the highest cellulolytic activity. The study yielded three species of endophytic fungi from betel leaf: Fusarium graminearum, Fusarium oxysporum, and Colletotrichum coccodes. All three samples showed positive results, producing cellulase enzymes characterized by the presence of a clear zone around the colonies. F. oxysporum was identified as the highest producer of cellulase enzymes, with a concentration of 0,033 U/ml.

Late leaf spot of groundnut is caused by the fungal pathogen of Cercosporidium personatum. Efforts to prevent this disease generally use synthetic fungicides that can cause environmental pollution. This study aims to identify the fungal pathogen of groundnut late leaf spot and study the antifungal effect of leaf extract of some plants for leaf spot intensity suppression. Late leaf spot pathogen was identified based on morphological characteristics of hyphae and conidia. The leaf extracts of butterfly pea (Clitoria ternatea), Mexican sunflower (Tithonia diversifolia), basil (Ocimum gratissimum), and sugar apple (Annona squamosa) at a concentration of 25% against C. personatum were evaluated in vitro based on growth inhibition. The growth and intensity of groundnut disease attacks were assessed for seven weeks by inoculating C. personatum and application of the leaf extracts. Results showed that the pathogen was identified as C. personatum with conidia characteristics of cylindrical to obclavate, short and slightly curved with four septa, and 35.75 × 7.11 µm in size. The percentage of inhibition of C. personatum in vitro reached 94.03% by leaf extract of C. ternatea, 88.56% by T. diversifolia, 87.20% by O. gratissimum, and 84.10% by A. squamosa. Treatment of C. ternatea increased plant height up to 12.85% and reduced the most optimal percentage of the infected leaves up to 61.53%. C. ternatea leaf extract was found to be the most effective extract to suppress C. personatum infection by 77.94%, while T. diversifolia, O. gratissimum, and A. squamosa reduced disease severity by 70.15%, 65.43%, and 57.76%, respectively.

Lansium domesticum Corr. known as duku, langsat, and kokosan is a popular fruit in Indonesia, particularly in South Sumatra. Furthermore, the fruit is cherished in this region because of the nice smell, sweet taste, and high economic value. Until now, South Sumatra local duku is rarely investigated, even though information on the genetic diversity of the germplasm is useful in supporting breeding and conservation programs. Therefore, this study aimed to determine the genetic diversity and phylogenetics of local duku and langsat (Lansium domesticum) based on matK gene DNA barcoding. DNA genome was extracted using Tiangen Plant Genomic DNA Kit DP305, then amplified using GoTaq Green Master Mix (Promega) and primers 3F_KIM-F and 1R_KIM-R. The product was sequenced by 1st Base Singapore and seven amplification results had a DNA size of 900 bp. The results showed that the matK gene is capable of determining Lansium domesticum interspecies. According to the DNA sequence phylogenetic analysis conducted using the maximum likelihood method, all the DNA samples were designated as Lansium domesticum Corr. with a fairly high genetic variation, indicated by DNA sequence differences caused by gene mutations.

ARTICLE HIGLIGHTS- Sorghum nutrition varies across varieties and growing seasons- Dry season increases starch and amylose content in some varieties- Rainy season enhances protein levels in sorghum grains- Genotype-environment interaction affects sorghum nutritional quality- Sorghum adaptation supports food diversification and climate resilienceABSTRACTSorghum (Sorghum bicolor (L.) Moench) is a potential staple food in Indonesia, offering an alternative to rice and corn due to its adaptability to marginal lands and drought tolerance. However, research on the impact of environmental factors, particularly different growing seasons, to the nutritional composition of sorghum varieties are still lacking. This study aimed to analyze the proximate contents of tannin and amylose in six sorghum varieties cultivated in two different planting seasons (wet and dry seasons). A Completely Randomized Design with three replications was applied in this experiment. The tested varieties included three newly developed superior varieties (Bioguma, Samurai, and Kawali) and three local varieties (Black Bonteb, Red Glutinous Sorghum, and KD4). The results showed that proximate composition varied across varieties and seasons. Starch content was generally higher in the dry season, with the highest observed in Kawali (64.16%) and Bioguma (63.11%), while the lowest was in Black Wareng (11.99%). Similarly, protein content peaked in Black Wareng (7.68%) and Red Glutinous Sorghum (7.37%), but was the lowest in Samurai (4.48%). Tannin levels also fluctuated by season, where Bioguma, KD4, and Kawali exhibited higher tannin content in the dry season, whereas Samurai, Red Glutinous Sorghum, and Black Bonteb had lower tannin levels. Notably, amylose content was significantly higher in Red Glutinous Sorghum (4.72%) and Black Bonteb (4.62%) across both seasons, contributing to their fluffier texture when cooked. These findings highlight the influence of environmental conditions on sorghum nutritional quality, reinforcing its potential for food diversification, including processed sorghum flour as a substitute for wheat flour.

Oil palm is the main vegetable oil-producing crop in Indonesia. Leaf spot disease is one of the major diseases that attacks oil palm seedlings at all seedling stages. In Indonesia, leaf spot disease in oil palm nurseries is most commonly caused by the genus Curvularia with an infection intensity of up to 60–70%. The control of leaf spot disease usually uses chemical fungicides but its continuous use can cause the development of resistant pathogen fungi and have a long-term negative impact on the environment. False elder (Peronema canescens Jack) leaves have bioactivity as an antimicrobial control disease caused by fungal infections. In this study, Curvularia was isolated from oil palm seedlings infected with leaf spot disease from oil palm nurseries in South Sumatra. Effectiveness testing of P. canescens leaves conducted by a Completely Randomized Design method with five treatments and three replications. The fungi that caused leaf spot disease in oil palm were identified as Curvularia eragrostidis. P. canescens leaf water extract at 25% concentration was very ineffective to quite effective in controlling disease severity based on the average number of spots and diameter of spots in oil palm with the values 36.25–59.50% and 12.50–27.78%. P. canescens leaf water extract could reduce the average number of spots and diameter of spots started on day 30 after being sprayed three times with P. canescens leaf water extract so that it could be used as an alternative to control C. eragrostidis leaf spot disease in oil palm that is more friendly to the environment.
