“…Moreover, during drought, heat, and salt stress, the EL values, MDA, and proline levels were signi cantly higher in the treated plant of Geumgangmil than in the control. The ndings are consistent with previous research ndings [90,92,93]. Genotype, treatments, and their interaction produce a signi cant effect on RWC, EL, MDA, proline, and the putative TaMATE genes (Table S3-S5).…”

To explore the response of multidrug and toxic compound extrusion (MATE) proteins to drought, heat, and salt stress in wheat, a genome-wide identification and expression study was performed. 20 MATE genes located on 4 of the 12 chromosomes were identified and categorized into four (I-1V) subfamilies, based on phylogenetic analysis. Wheat MATE family expansion was primarily driven by whole-genome duplication (WGD) and tandem events. In the same subfamily, gene exon-intron structures and motif composition are more similar. TaMATE genes had cis-acting elements that were implicated in stress and defense response. Tae-miR5175e was identified as the highly expressed miRNA that targets TaMATEs by miRNA prediction. When compared to controls, the relative expression patterns of seven TaMATE genes were substantially elevated during drought stress. TaMATE2, 10, 13, and 14 expression levels considerably elevated after 15 days (d) of heat stress, whereas TaMATE2, 14, 18, and 20 expression levels were highly upregulated following 15 d of salt stress treatment, indicating the crucial role of TaMATEs under these abiotic stress conditions. Furthermore, drought, heat, and salt stress decreased wheat water content, but increased malondialdehyde (MDA), electrolyte leakage (EL), and proline content, whereas the expression of the 7 putative MATE genes was correlated with physio-biochemical indicators of these stress conditions. The findings contribute to a better understanding of the complexities of MATEs and present a theoretical base for future MATE gene discovery and application in wheat and other crop species.

“…Severe weather incidents analysed for the period 1964-2007 were shown to profoundly affect crop harvest worldwide due to drought and heat (Lesk et al ., 2016). This has been reported in rice (Peng et al, 2004; Guo et al , 2019), maize (Liu et al , 2020), wheat (Liu et al , 2016), soybean (Zhao et al , 2017), tomato (Singh et al , 2017), and cotton (Singh et al , 2007). Predicted increase of temperatures in the future will deepen problems with crop yield (Zhao et al, 2017), which encourages scientific efforts in the production of thermotolerant (or stress-tolerant) cultivars.…”

Brassica napus is the second most important oilseed crop worldwide. Increasing average temperatures and extreme weather have a severe impact on rapeseed yield. We determined the response of three cultivars to different temperature regimes (21/18 °C, 28/18 °C and 34/18 °C), focusing on the plant appearance, seed yield, seed quality, seed viability, and embryo development. Our microscopic observations identified that embryo development is affected by high temperatures. We noticed an acceleration of its development, in addition to pattern defects. Reduced fertilization rate, increased abortion rate, and preharvest sprouting would be responsible for the low seed yield at the high-temperature regime. Hormone profiling indicates that reduced auxin levels in young seeds may cause the observed embryo pattern defects. Moreover, reduced seed dormancy may result from low ABA and IAA levels in mature seeds. Glucosinolates and oil composition measurements suggest reduced seed quality. These identified cues help understand seed thermomorphogenesis and pave the way to the development of thermoresilient rapeseed plants.

“…Proses aerobik yang bersifat bolak-balik dalam proses pembentukan ATP dapat menghasilkan gerak dan panas sehingga akan mempengaruhi pembentukan bunga (Hanafiah, 2014). Menurut Liu et al, (2020) tekanan panas yang dihasilkan dapat merangsang pembungaan. Namun, jika berlebihan justru menyebabkan polinasi menjadi terhambat (Wu et al, 2020).…”

Pengaruh Dosis Rhizobium dan Pupuk Kandang Kambing pada Pertumbuhan dan Hasil Tanaman Kacang Tanah (Arachis hypogea L.)

Kacang tanah (Arachis hypogea L.) merupakan tanaman pangan yang memiliki nilai ekonomis tinggi. Ada banyak produk turunan yang dihasilkan diantaranya tepung, pasta, kue, selai, mentega, susu, permen, aneka minuman, bumbu, sambal, oncom, pakan ternak dan lain-lain. Namun, sampai saat ini produktivitas kacang tanah masih tergolong rendah. Hal tersebut dikarenakan kacang tanah dibudidayakan di lahan yang kurang subur sehingga tidak mendapat unsur hara dalam jumlah yang cukup. Inokulum rhizobium (legin) dan pupuk kandang kambing adalah bahan organik yang dapat memperbaiki sifat fisik, kimia dan biologi tanah. Tujuan penelitian ini untuk mempelajari interaksi antara rhizobium dan pupuk kandang kambing terhadap pertumbuhan dan hasil kacang tanah. Penelitian ini dilaksanakan di Kebun Percobaan Jatimulyo, Fakultas pertanian, Universitas Brawijaya pada bulan Febuari-Mei 2020. Penelitian ini merupakan percobaan faktorial yang disusun menggunakan Rancangan Acak kelompok (RAK) dengan 9 perlakuan yang diulang sebanyak 3 kali. Data hasil penelitian dianalisis menggunakan analisis ragam (ANOVA) dan diuji menggunakan F table pada taraf 5%. Apabila ditemukan pengaruh nyata dilanjutkan dengan uji Beda Nyata Jujur (BNJ) taraf 5%. Hasil penelitian menunjukkan bahwa perlakuan legin 15 g kg -1 benih memberikan respon pertumbuhan lebih baik dibandingkan perlakuan lainnya. Pemberian legin 15 g kg -1 benih dan pupuk kandang kambing 10 ton ha -1 memberikan hasil panen paling baik dengan hasil 3,6 ton ha -1 . Secara umum, pemberian legin dan pupuk kandang kambing tidak memberikan pengaruh nyata terhadap variabel pertumbuhan dan hasil kacang tanah.
