高度で精密な生物機能の発現と調節の観点から、酸素・窒素と似て非なるイオウ・リンなどの第3周期以降の重ヘテロ元素を含む有機重ヘテロ元素化合物の触媒合成を基盤とした新しい化学領域を開拓した。安価なイオウ単体の直接利用法・塩基を使わない省エネルギー反応・可逆反応による有機重ヘテロ元素化合物の合成などの新しい合成方法論を提供した。加えて、一般に有機溶媒中で行われる遷移金属触媒反応を水中均一系で実施して、合成ペプチド・タンパク質の触媒的な化学修飾に展開した。これらの知見を基に酵素やタンパク質の動的挙動に着目して、生体親和性が高く柔軟な構造として2種の異なる複素環を1または3原子のヘテロ原子リンカーで連結した「非対称ビス複素環構造」を分子設計して、 in vivo で活性を有する新しい医農薬剤の開発研究を実施した。このような医農薬剤開発のアプローチは世界的に見て例がなく先導的である。

Cladosporium species are active in protecting plants against different biotic and abiotic stresses. Since these produced a wide range of secondary metabolites responsible for the adaptation to new habitats, plant health performance, they great interest, especially biostimulants agriculture. sp. produces protein hydrolysates (PHs), class biostimulants, by cultivation on medium with keratin waste...

Abstract The aim of this study was to find alternatives (even partial) mineral nitrogen fertilization reduce its harmful accumulation in the edible parts fennel. Fennel ( Foeniculum vulgare ) is a perennial plant Apiaceae family grown for shoots, leaves, and seeds. present work conducted two successive seasons, 2018/2019 2019/2020, at farm Agricultural Botany Department, Faculty Agriculture, Ai...

The use of biostimulants in crop production can be an economically viable option for farmers and enable them to meet the increasing quality standards agricultural products consumer expectations sustainability environmental protection. aim this study was determine effect foliar application on course physiological processes pea (Pisum sativum L.) plants.

Drought is a major constraint for agricultural production worldwide and likely to become aggravated by global warming. It can induce land degradation, exorbitant food prices menace livelihoods. Approaches retaining optimal yield, especially in rainfed staple crops such as cowpea [Vigna unguiculata (L.) Walp] are paramount. Biostimulants vermicompost leachate (VCL), seaweed extract [Kelpak® (KEL...

ABSTRACT Biostimulants currently available on the market include those containing seaweed extract. There is sufficient scientific evidence to conclude that applying biostimulants agricultural crops can positively impact plant growth and yield. However, results differ between plants species environmental conditions. As such, present study aimed assess effects of doses application times a biostim...

Peppers (Capsicum annuum) are one of the most widely cultivated vegetable crops, with per capita consumption bell and chile peppers being 11.4 7.7 pounds in 2017. Biostimulants an emerging sustainable alternative to enhance plant health by increasing photosynthetic activity, stress tolerance, nutrient uptake through various modes action. The effects different biostimulant applications largely r...
