“…Akar adventif berperan membantu transportasi gas, air, serta serapan hara ketika tergenang. Hal tersebut sesuai dengan hasil penelitian Nguyen et al (2018) menjelaskan bahwa akar adventif yang muncul di daerah batang ketika terjadi genangan dapat meningkatkan hormon auksin (IAA) dan giberelin (GA) namun dapat menurukan sitokinin dan asam abisat (ABA). Hal ini merupakan salah satu bentuk adaptasi tanaman untuk kelangsungan hidup tanaman di bawah cekaman genangan.…”

Maize is an important crop in Indonesia that is utilized for food, feed, and industry. Waterlogging is one of the abioticstresses challenging maize production in recent years due to climate changes. Vegetative-phase screening methods may benefitplant breeding programs because potential genotypes can be identified at earlier stage with lower cost. This study consistedof two experiments. The first experiment was carried out at the Sawah Baru experimental station of Bogor AgriculturalUniversity (IPB), Bogor, from June to September 2017 using an alpha lattice design with three replications and four blockswithin each replication. The second experiment conducted in a greenhouse at Cikabayan experimental station of IPB, Bogor,from December 2017 to January 2018 using a randomized complete block design with three replications. Genetic materialused were 21 maize genotypes from the Indonesia Cereal Research Institute (ICERI) and IPB, including 19 hybrids and 2inbred lines. The results showed that the dry root weight under normal conditions had significant positive correlation withgrain yield under waterlogging stress, and therefore is potential for early screening. Adaptive genotypes in waterloggingstress selected based on dry root weight are DKLx30, DKLx11, MGoldx37, MGOldx41, and IPB L15-1xMR14. Predictedmean yield across these genotypes was 0.57 ton ha-1 higher yield than the overall mean in waterlogging stress condition.Selected hybrids can be further evaluated for variety release.

“…Plants can adapt to WL with changes in morphology, anatomy, and metabolism [4]. Development of a shallow root system and formation of aerenchymatous adventitious roots are the main morphological/anatomical changes [5,6], and are controlled by plant hormones such as ethylene, auxin, abscisic acid (ABA), cytokinin, jasmonates (JAs), and gibberellin (GA) [4]. In rice, lysigenous aerenchyma and a barrier to radial O 2 loss form in roots to mitigate WL stress by supplying O 2 to the root tip [7].…”

Background: Waterlogging is one of the major abiotic stresses limiting wheat product. Plants can adapt to waterlogging with changes in morphology, anatomy, and metabolism. Many genes and proteins play critical roles in adaptation to waterlogging. Results: the iTRAQ-based proteomic strategy was applied to identify the waterlogging-responsive proteins in wheat. A total of 4,999 unique proteins were identified in two wheat varieties, XM55 (waterlogging-tolerant) and YM158 (waterlogging-sensitive), at anthesis under waterlogging or not. Sixteen proteins were differentially accumulated between XM55 and YM158 under waterlogging with cultivar specificity. Of these, 11 proteins were up-regulated and 5 proteins were down-regulated. The up-regulated proteins included Fe-S cluster assembly factor, heat shock cognate 70, GTP-binding protein SAR1A-like, and CBS domain-containing protein. The down-regulated proteins contained photosystem II reaction center protein H, carotenoid 9,10 (9',10')-cleavage dioxygenase-like, psbP-like protein 1, and mitochondrial ATPase inhibitor. In addition, 9 proteins were responsive to waterlogging with non-cultivar specificity. These proteins included 3-isopropylmalate dehydratase large subunit, solanesyl-diphosphate synthase 2, DEAD-box ATP-dependent RNA helicase 3, and 3 predicted or uncharacterized proteins. Conclusions: This study revealed that the proteins were differential accumulated between the two contrast waterlogging wheat varieties in response to waterlogging, which provide valuable insights into wheat response to waterlogging stress. These differentially accumulated proteins might be applied to develop waterlogging tolerant wheat in further breeding programs.

“…According to recent anatomical studies in Arabidopsis thaliana, founder cell 62 division gives rise to AR primordial (ARP), which then develops into a new root 63 (Della Rovere et al, 2013). Similar to that of primary or lateral roots (LRs), the 64 indeterminate growth of AR depends on cell division and elongation, which are 65 affected by various environmental conditions (Nguyen et al, 2018). AR formation is 66 regulated by almost all major plant hormones, with auxin strongly promoting the 67 process (Elmongy et al, 2018).…”

20 Adventitious root (AR) formation is critical for the efficient propagation of 21 elite horticultural and forestry crops. Despite decades of research, the cellular 22 processes and molecular mechanisms underlying AR induction in woody plants 23 remains obscure. We examined the details of AR formation in the apple (Malus 24 domestica) M.9 rootstock, the most widely used dwarf rootstock for intensive 25 production, and investigated the role of polar auxin transport in post-embryonic 26 organogenesis. AR formation begins with a series of founder cell divisions and 27 elongation of interfascicular cambium adjacent to vascular tissues. This process 28 was associated with a relatively high indole acetic acid (IAA) content and 29 hydrolysis of starch grains. Exogenous auxin treatment promoted cell division, 30 as well as the proliferation and reorganization of the endoplasmic reticulum and 31 Golgi membrane. By contrast, treatment with the auxin transport inhibitor 32 N-1-naphthylphthalamic acid (NPA) inhibited cell division in the basal region of 33 the cutting and resulted in abnormal cell divisions during early AR formation. In 34 addition, PIN-FORMED (PIN) transcripts were expressed differentially 35 throughout the whole AR development process, with the up-regulation of 36 MdPIN8 and MdPIN10 during induction, an up-regulation of MdPIN4, MdPIN5 37 and MdPIN8 during extension, and an up-regulation of all MdPINs during AR 38 initiation. This research provides a deeper understanding of the cellular and 39 molecular underpinnings of the AR process in woody plants. 40 41
