Stress caused by pathogens strongly damages plants. Developing products to control plant disease is an important challenge in sustainable agriculture. In this study, a heat-killed endophytic bacterium (HKEB), Bacillus aryabhattai, used induce defense against fungal and bacterial pathogens, the main pathways HKEB activate are revealed. The induced high protection different through salicylic jasmonic acid pathways. We report presence of gentisic for first time. These results show that HKEBs...

Broussonetia papyrifera has a high lignocellulose content leading to poor palatability and low digestion rate of ruminants. Thus, dynamic profiles fermentation characteristics, microbial community structure, potential function, interspecific relationships B. mixing with wheat bran in different ratios: 100:0 (BP100), 90:10 (BP90), 80:20 (BP80), 65:35 (BP65) were investigated on ensiling days 5, 15, 30, 50. The results showed that adding increased the degradation hemicellulose, neutral...

Abstract Pineapple, Ananas comosus L. Merr., cultivars differing in resistance to fusariose were examined for the phytotoxic effect of culture nitrate (CF), and fusaric acid (FA) isolated from Fusarium subglutinans (Wollew & Reinking) Nelson, Toussoun Marasas. The possibility using these substances on F 1 hybrids as selection agents was also evaluated. assessed pineapple plantlets tissue by placing them wounded leaf segments. level under natural conditions measured greenhouse field...

Banana is a major tropical fruit crop but banana production worldwide seriously threatened due to Fusarium wilt. oxysporum f. sp. cubense ( Foc ), the causal agent of wilt (also referred as Panama disease) an asexual, soil inhabiting facultative parasite. isolates can be classified into three races that are not defined genetically, for their pathogenicity different cultivars. Despite mycotoxins being some best studied virulence factors phytopathogenic fungi and these have been useful...

Fertilization is an important measure to quickly supplement the soil nutrients required for plantation productivity. However, response patterns of microbial community and functional taxa in Larix root, rhizosphere, bulk short-term consecutive fertilization have rarely been reported. In this study, we assessed on days 0, 5, 15, 30 after first inorganic three years fertilization. The bacterial 16S fungal ITS high-throughput sequencing technology were used monitor changes composition potential...

Pineapple producing countries lack good quality propagation material to expand cultivars into new areas. Previously, research protocols may increase the offer of high plantlets and speed introduction pineapple cultivars. The present work is evaluate morpho-physiological changes in [Ananas comosus (L.) Merr. 'MD-2'] during acclimatization phase. Plantlets were acclimatized under 80% relative humidity, 25.5 °C temperature photosynthetic photon flux 400-500 µmol m-2 s-1 as average for 45 d...

The jacalin-related lectins (JRLs) are widely distributed in plants and involved plant development multiple stress responses. However, the characteristics of HvJRL gene family at genome-wide level roles JRLs barley’s response to low-nitrogen (LN) have been rarely reported. In this study, 32 genes were identified unevenly both ends seven chromosomes barley. proteins generally exhibited low sequence similarity but shared conserved jacalin domains by analysis. These classified into subfamilies...

Bananas and plantains ( Musa spp.) are among the most important crops in world providing staple food for hundreds of millions people. However, banana production has been devastated by fungal infestations caused Fusarium oxysporum f. sp. cubense (Foc). Despite fact that there is very little known on role microbial metabolites molecular mechanism Foc infections, it proposed toxins fusaric acid beauvericin produced play an during pathogenesis. The aim this contribution was to study toxic...

Abstract Among the most important crops in developing countries are banana and plantain. However, production is threatened by increasingly virulent forms of Fusarium wilt, therefore, intensive breeding programmes being carried out worldwide. As conventional field studies resistance to this disease time‐consuming destructive, an easy‐to‐do procedure was previously developed differentiate field‐grown resistant susceptible cultivars at leaf level. Such a involved vitro treatment fungal culture...

En trabajos previos se desarrolló un método para la diferenciación a nivel foliar de resistencia cultivares banano marchitez por <em>Fusarium</em>. El presente estudio realizó con el objetivo evaluar rápida enfermedad mediante utilización del filtrado cultivo <em>Fusarium oxysporum</em> f. sp. <em>cubense</em> raza 1 GCV [01210] y 2 [0124/125]. Se procedió obtención filtrados hongo durante crecimiento <em>in vitro</em> patógeno. determinó...

Many host genes induced during compatible plant–pathogen interactions constitute targets of pathogen virulence factors that act to suppress defenses. In order identify Nicotiana tabacum L. for pathogen-induced proteins involved in susceptibility the oomycete Phytophthora parasitica var. nicotianae, we used SuperSAGE technology combined with next-generation sequencing transcripts were differentially upregulated a interaction. We identified gene (NtPIP) was rapidly only Virus-induced silencing...

Protease secretion is crucial for degrading nematode cuticles using nematophagous fungus Purpureocillium lilacinum , but the pattern of protease remains poorly understood. This study aimed to explore degradation mechanism proteases by investigating characteristics under various carbon and nitrogen sources, different (C:N) ratios in P. . The results showed that corn flour as a source yeast extract specifically induced lilacinum. produced significant amounts gelatinase casein enzyme at C:N...

Paper mulberry ( Broussonetia papyrifera ) is a high-quality silage protein feed material that can help address shortages and support livestock development.
