SUMMARYAnther infertility under high temperature (HT) conditions is a critical factor contributing to yield loss in cotton (Gossypium hirsutum). Using large-scale expression profile sequencing, we studied the effect of HT on cotton anther development. Our analysis revealed that altered carbohydrate metabolism or disrupted tapetal programmed cell death (PCD) underlie anther sterility. Expression of the Gossypium hirsutum casein kinase I (GhCKI) gene, which encodes a homolog of casein kinase I (CKI), was induced in an HT-sensitive cotton line after exposure to HT. As mammalian homologs of GhCKI are involved in inactivation of glycogen synthase and the regulation of apoptosis, GhCKI may be considered a target gene for improving anther fertility under HT conditions. Our studies suggest that GhCKI exhibits starch synthase kinase activity, increases glucose content in early-stage buds and activates the accumulation of abscisic acid, thereby disturbing the balance of reactive oxygen species and eventually disrupting tapetal PCD, leading to anther abortion or indehiscence. These results indicate that GhCKI may be a key regulator of tapetal PCD and anther dehiscence, with the potential to facilitate regulation of HT tolerance in crops.

“…Cotton cultivars even ecotypes within species differ for their temperature sensitivity. Differences in phenological stages; time requirement varied for square; flower and boll maturation are strongly influenced by environment (Singh et al, 2007). Adding to the above fact, cotton cultivars respond differently to early sever heat stress due to differences in canopy development, crop growth cycle and adaptation mechanisms.…”

“…Conventional cultivars sown too early, heat stress effect reproductive development (Bibi et al, 2003) and cultivars shed their early reproductive parts completely and assimilates promoted excessive biomass production and affected the harvest index . Optimum temperature for efficient growth is reported to be 33 °C while significantly reduction in flower and boll retention has been recorded above 36 °C (Singh et al, 2007). However, optimum range for different sowing window is not well defined in the country and it varies among varieties as well.…”

Suitable cotton variety selection is imperative to cope with temporal variations for yield enhancement and sustainability under unpredictable climatic conditions. Cotton varieties including transgenic (Bacillus thuringiensis) and non-transgenic (non Bt.) were sown from 10-March to 21-June with 20 days interval for two growing seasons (2012 and 2013) consecutively while cotton sowing after wheat harvest is normal practice at farmers' field in Cotton-Wheat cropping system of Punjab-Pakistan. Phenology, growth indices, seed cotton yield (SCY) and its heat use efficiency of varieties were estimated on daily basis by using statistical models. Seed cotton yield (SCY) was significantly correlated with crop duration exhibiting delays in planting (21-June) impact on shortening of phenophases i.e. first square, flower, boll initiation and boll opening by 8, 7, 4 and 6 days, respectively compared with 10-May planting in first season while second season advanced 0-3 days owing to deviation in frequency of cold shock <11 °C and heat stress >35 °C. Long crop cycle varieties AA-802 and IR-3701 took 6-9 days more compared to short season NIAB-112. More heat units accretion 46, 33, 20 and 13 % to switch into next phenophase (first square, flower, boll initiation and boll opening) was computed in 10-May planting than 10-March due to excessive heat stress (>40 °C) during early phenophases while reduced variations observed in later phases. Reproductive stage initiation and accumulated higher thermal time delayed in late mature varieties compared to short one with lower root mean square error (RMSE) and higher coefficient of determination (R 2 ). Significant reduction in days after planting to attain maximum LAI, CGR, TDM and SCY-heat use efficiency (HUESCY) decreased with delay in planting with good statistical indices. Less impact of cold shock and heat stress on 21-April and 10-May plantings noted while 10-March and 21-June planting had higher incidence during early growth phases. Cotton varieties MNH-886 and NIAB-9811 (NIAB-Kiran) planted 30-March to 10-May exhibited higher resilience to variable weather conditions with fostered growth potential and yield. Variety NIAB-112 seemed heat tolerant and it can be recommend for early and especially for late plating while MNH-886 and NIAB-Kiran can be adopted at farmer's field in the region for maximizing cotton production under variable environment.

“…In general, the buds of cotton begin to appear at 40 to 45 d after seedling emergence, and the cotton plant reaches a peak in budding and flowering in late July; interestingly, in China, HT occurs most frequently in July. Thus, cotton is seriously subjected to yield decreases of approximately 110 kg ha 21 for each 1°C increase in ambient temperature (Singh et al, 2007), due to HT causing cotton pollen abortion, anther indehiscence, and boll shedding. However, few studies have focused on the molecular mechanisms of HT-induced reproductive sterility in cotton, although other crops, such as rice (Oryza sativa; Jagadish et al, 2007), wheat (Triticum aestivum; Saini et al, 1984), and barley (Hordeum vulgare; Oshino et al, 2007), have been investigated.…”

Sugar and Auxin Signaling Pathways Respond to High-Temperature Stress during Anther Development as Revealed by Transcript Profiling Analysis in Cotton

et al. 2014

Male reproduction in flowering plants is highly sensitive to high temperature (HT). To investigate molecular mechanisms of the response of cotton (Gossypium hirsutum) anthers to HT, a relatively complete comparative transcriptome analysis was performed during anther development of cotton lines 84021 and H05 under normal temperature and HT conditions. In total, 4,599 differentially expressed genes were screened; the differentially expressed genes were mainly related to epigenetic modifications, carbohydrate metabolism, and plant hormone signaling. Detailed studies showed that the deficiency in S-ADENOSYL-L-HOMOCYSTEINE HYDROLASE1 and the inhibition of methyltransferases contributed to genome-wide hypomethylation in H05, and the increased expression of histone constitution genes contributed to DNA stability in 84021. Furthermore, HT induced the expression of CASEIN KINASEI (GhCKI) in H05, coupled with the suppression of starch synthase activity, decreases in glucose level during anther development, and increases in indole-3-acetic acid (IAA) level in late-stage anthers. The same changes also were observed in Arabidopsis (Arabidopsis thaliana) GhCKI overexpression lines. These results suggest that GhCKI, sugar, and auxin may be key regulators of the anther response to HT stress. Moreover, PHYTOCHROME-INTERACTING FACTOR genes (PIFs), which are involved in linking sugar and auxin and are regulated by sugar, might positively regulate IAA biosynthesis in the cotton anther response to HT. Additionally, exogenous IAA application revealed that high background IAA may be a disadvantage for latestage cotton anthers during HT stress. Overall, the linking of HT, sugar, PIFs, and IAA, together with our previously reported data on GhCKI, may provide dynamic coordination of plant anther responses to HT stress.
